Awesome tutorial. Thank you! I just did this to mine and my memory temperatures are down 15-20C. Some additional tips: * After you detach the cables, it helps a lot to use a few pieces of tape to hold them back and keep them out of the way. * Don't try to cut the thermal pad with scissors - it squashes the edges. Just use a knife and ruler, it's easier. * The thermal pad has a smooth side with clear plastic, and a rough side with blue plastic. The smooth side is stickier, and you want to put this side down on whatever surface you're placing the pads on. Remove the clear plastic before applying the pads. You can leave the blue plastic on until you reassemble, to avoid getting dust and fingerprints on that side. * I drew the pieces out on paper before cutting to make sure everything would fit within the 85x45mm pad dimensions. I used 3 pads and had a little left over. * All the pieces are symmetric, except for the two with diagonals. Make sure you cut the diagonal pieces the right way round! I did them backwards so I had the rough side facing down, and they fell off during reassembly. * I repasted the GPU with Noctua NT-H1. To my surprise, GPU temps actually increased from ~65C before the mod to ~75C. I think this is because the GPU is no longer throttling on mem temps and can run at higher load (this is reflected in higher overall power use and GPU clocks), and the fans are also running more slowly than before. My fans used to run at 2700rpm constantly when the card was under load, but now they run at around 1400-1500rpm, so the GPU isn't being cooled as much. If I force them to run at 2700rpm using Afterburner, my GPU temps fall back to slightly less than before the mod, which is now I know the repaste was successful.
@@CryptoAtHome I'm curious about your GPU temps at idle and under load. It looks like your GPU is at 37C while mining, which seems amazingly low - mine is at 35C just idle and hits 75C mining. What’s the ambient temperature in the room, and do you have any additional heatsinks or fans on the card? My ambient is around 25C and I have a 2070 Super installed underneath which may be limiting airflow...
Right now it's getting hotter here and all the mining rigs are generating a ton of heat in my apartment which I'm having a very hard time evacuating. With current ambient temp and a whole mining rig nearby, I'm at 38 degrees idle for the gpu temp and 52 mining. I have 5 Noctua NF-A12 pulling and pushing air in the case at a constant high speed and the side of the case is open. 75 seems pretty high though. Was you gpu thermal paste really dry ? Did you change it ? Also , did you lower the gpu core speed to the minimum ? (-500 in Afterburner). Did you lower the power limit to maximum of 90 (or lower)? I had a small heatsink which I removed after doing the mod and I have one extra fan that is pushing air from the open side right onto the backplate.
@@CryptoAtHome Thanks for the additional information! I'm pretty sure the culprit was having the 2nd GPU below it, limiting airflow and increasing air intake temps for the 3090. With the 2nd GPU removed, my GPU temp is 54C when mining using the same settings as you (80% power, -502 core, +1056 mem, 70% fan). The remaining 2C is probably because I have the case closed vs yours open, and your extra fan. I'll have to improve my cooling for dual GPU or mount the 2nd GPU externally, or go water. For now I'm going to put some heatsinks and a fan on the 3090 backplate, and add a side fan to get more air between the two GPUs. The original GPU thermal paste was completely dry and I repasted with NT-H1.
Guys, if your gpu temps went up after this mod, its because original gpu side thermal pads are softer and thinner then Thermalright 1.5mm. So the heatsink doesn't have such a tight contact with gpu as with original pads. It has nothing to do with throttling or low frequencies. I would recommend to flatten Thermalright pads little bit for gpu side or use softer pads like Gelid Extremes. Also repaste gpu, use twice more thermal paste then you usually apply for cpu.
Since I want to reduce the overall VRAM temp and fan speed on my 3090 FE, I consider to try this mod out. Would you recommend using 1mm thermal pads for all parts instead of the 1.5mm pads?
Great video, thank you! I did this on my hottest running card and it went to become the coolest one, very happy! A few minor things: 1) The 4 torx screws holding the GPU chip are size 6, not 5. 2) The little magnetic screw caps are labeled D, E, F, G on the inside: They go on this way: F----------------D\. / RTX 3090 X G----------------E/. \ 3) Two of the 120x120mm pads will cover three cards Cheers!
@@CryptoAtHome I also stuck a few little aluminum heatsinks on the backplate which -- while it's not pretty -- reduced the memory temperature even further
Brilliant tutorial and the sizes were a huge help. If anyone is in doubt about doing this, just go ahead and do it. The only thing to really be careful of is the small wires, the rest of it is easy. My results with mining after 25 minutes with no over/under clocks: Before swapping pads - Memory temp - 112 Degrees Core temp - 55 Degrees Hashrate - 99-101 MH/s Power Usage - ~262W Gelid Extreme 2mm pads- Memory temp - 94 Degrees Core temp - 62 Degrees Hashrate - 107-108 MH/s Power Usage - ~339W Extreme Odyssey 1.5mm pads- Memory temp - 89 Degrees Core temp - 63 Degrees Hashrate - 108-109 MH/s Power Usage - ~340W Also getting about a 7-8% fps boost in Cyberpunk on max settings. I think what was happening before was my GPU was throttling based on the memory temps which is why the power usage was so low at ~262W. I think this also explains why the core temp is higher because of the higher power usage. Also I wasn't very comfortable leaving my card mining sitting at 110+ Degrees but 89 is totally fine. I would like to try the Gelid Ultimate pads though with their claimed 15 W/mK heat conductivity compared to the Gelid extreme's 12 W/mK and the Extreme Odyssey's 12.8 W/mK. But I can't find the Gelid ultimate anywhere in the UK If anyone from Nvidia sees this video your thermal pads are garbage and come off like old chewing gum with some silly mesh fabric on them. Cut that shit out Nvidia
Thanks, nice results. As for Gelid, I'm not convinced the higher model would make a meaningful difference. Maybe if one goes for the Fujipoly at 17 W/mK
I saw your news on notebookcheck, and my god, you're jst a small youtuber, yet you found a solution to reduce the heat of the rtx 3090 is very impressive, btw great tutorial vid
Haha thanks. Not sure what does being a small or a big youtuber changes though. If I'm a small youtuber who works as a Tech Lead in life and there is someone else which has 100 times more subscriber and delivers pizza, who would you trust more ? ;)
Love the thoroughness of this video. I am a bit shocked that you didn’t re-paste the GPU itself. I have always done this on my cards. The NVidia thermal paste is pretty terrible just like their pads. Nice job again.
Dude thank you so much for the in-depth tutorial. I followed it exactly as you explained and I am seeing the exact same improvements on my 3090. This video gave me the complete confidence to take apart a $1500 GPU and it worked perfectly! This was literally my first time taking apart a GPU haha
Thank you for the detailed process i did this because my 3090FE kept having fan Reving issues so bought the Kryptonite pads but that didn't fix it so bought 4 packs of 1.5mm pads some thermal Grizzly bubble gum and reapplied much better no more desktop crashes and hot spot sitting at a cool 54c while gaming.
thank you for the detailed guide. been debating about doing this on my 3090 fe since i got it on launch. finally bought the thermal pads and used your guide as a step by step guide.
Excellent tutorial, I've just done this to my 3090 FE and seeing 20-25C decrease in thermal junction temperature also. Now able to drop fan and getting: 95C TJT 56C GPU @ 55% Fan - 121MH/s
Just wanted to say thank you for the video. Did my thermal pads and thermal paste and ran the miner for about 6 min... Thermal junctions from 104-106 at 100% fan speed to.... 84 on the thermal junction with fans at 80%! Wasn't the the easiest thing to do when you look at the cost of the card but my only regret is not doing it sooner!
Fantastic video. I needed a video with this level of detail before trying it myself, and I'm happy to say I brought my memory temps down from 102c with a memory downclock to 88c with a modest overclock. Thanks!!
Thank you so much for this - I have great airflow in my case but Final Fantasy 14 still hit around 104 flippin degrees on the memory in HWmonitor with very noticeable fan noise. I did the mod precisely as instructed and now it seems to be at 86 with INAUDIBLE fans (on my custom curve in afterburner). You're awesome for this.
I’m a newbie and it was my first time ever taking apart a graphic card. I was able to get take it apart, take off the old thermal paste and pad, clean it, and reapply the new thermal pad and paste, and put it back together in 3 hours. I think I strip one of the magnet screw but it works. Drop the temperature from 105c to 90c for mining. Man that was scary and I thought I broke it 😂 thank you very much and very informative and on point.
Totally works! -20 deg C (or more!). I used the exact recommended thermal pad brand and size. 3 packages is plenty. Thanks for the detailed measurements of the thermal pad cut size. That saved me at least 30 mins of tediousness. I just can't believe it works so well! Even as I was putting the pads in, I'm thinking... there's no way this will help much. I was mining for 1 week on my stock 3090 FE. I could barely run +300 Memory. I was at 108C with lowered core(-150) and power at (82), fan at max. Getting 108Mh on NiceHash QM. Now I'm running +1350 Memory, Fan speed lowered to 65, with 88 deg C temps. 120 Mh! As some extra help, I use 2 oem CPU heatsinks (with the fans removed because of space) on top of the backplate. This helps remove another 2 - 4 degree C. Thanks again, great video!
Yeah I think we're all suprised how bad the original thermal dissipation is and how much better it is after replacing the pad with some cheap aftermarket ones. Enjoy your modded 3090 FE!
I got my RTX 3090 FE and haven't used it for over a year before finally putting it into my rig. It was a barely used unit anyway, it didn't even have the firmware update for resizable BAR installed when I got it. I heard about this problem but haven't looked into it until now. MSI Afterburner reported a thermal limit on the OSD when playing a game and it surprised me because the core was around 70C. I don't usually use the OSD because it can cause issues, but I'm glad I did. I loaded up AIDA64 only to find the VRAM was maxed out at 110C. I'm glad this doesn't look too difficult so I will definitely be trying it, along with using my Alphacool Apex thermal grease for the core. Probably easier than redoing the thermal paste on my laptop by the looks of things as far as disassembly. Thank you so much for making this video.
Another success story for me too: from 104 to 86 degrees. Another piece of advice for people doing this mod; I read on the original overclock thread that someone had good results just replacing the pads on the top of the PCB. I tried just replacing the top pads and only saw about 2-4 degrees difference. My advice is just do the whole PCB, even though the underside is daunting.
As far as I've seen, the best you can get doing one side is 8 degrees. But it doesn't make sense to do that because you'll have one side burning hot and throttling and the other would be fine. Either do the whole mod or don't imho.
@@CryptoAtHome I got almost 20 doing only the top side with Gelid ultimate 15W/mK, you might want to look into those pads for even better cooling. They are cheaper than the pads you used, at least in the US. It was hitting 110 but now holding at 92 degrees even at 100% power limit +1000 on the mem clock. Also have a couple tiny heatsinks on the back plate with a fan blowing on them, those didnt do anything for temps before I replaced the pads though.
OMFG! I just finished my mod. Same exact pads and placement as you and I am 24 degrees cooler at the same setting. I can up my memory now to over 1000 bump my power limit up to 80, same fan speed and I am getting 20 percent better hashrate. Oh and I can close my case side and still be 15 degrees cooler than before. I want to thank you so much for this video. A couple things I want to recommend. Don't put your pads on the backplate side until you have put the board back onto the cooler and reattached the IO plate. It's too easy for the pads to fall off.
Merci cher compatriote pour ce magnifique tutoriel ! I've done exactly as said in this video now my hashrate goes 116/118mhs fully stable, no incorrect shares, with temps of 45°max for core, and 82 for memory ! •My settings are -150 core, +900 mem, power limit 305w, fan 60% •I just prepared all my pads in advance thanks to the PDF in description, then when I started to open the GPU all I had to do was clean and put my already cut pads according to the description. My GPU is brand new so I managed to take back the original pads properly in case of RMA I can put them back inside. •As seen on other comments and posts, taking off the SLI cover before reassembly will let you gain more pressure on the PCB in order to have the best contact with the thermal pads, especially if you have the Thermalright pads. • I used the thermalright pads, I was afraid because I've seen later that the Gelid would be better. But if you follow the instructions it'll be OK. Press gently the pads with your fingertips. • I repasted the chip with MX4 paste, spread all over the chip and in the end a little drop more on the center of the chip (just in case)
I just finished doing this to mine. My vram temp is only down from about 105 to 96, which is a little disappointing after seeing what others have gotten, but it’s a definite improvement. My tip is to print the layout thats in the description at 64% scaling and it comes out the right size to use as a template.
I am seeing about the same results as you. Disappointed in the small drop in temperature but at least now I can get around a 115mh/s / 102 degrees (102 degrees / 99mh/s before mod).
Don't focus too much on the temps. Micron has changed the optimal temps of the GDDR6X to 105 degrees max so as long as you're not throttling then your mod is successful.
Liked and subscribed got a 3090fe was hitting 104c on memory just gaming followed your guide now hitting a max of 84c on memory absolutely blown away thanks for all the information and that led connection was a fiddly sausage but got there in the end thanks a million
Thank you so much!! Well made tutorial!! The best! My temps are similar at first hitting 110c after this following this video exactly I’m getting 88c running even higher OC and getting 111MH/s!
Thank you so much for this tuto ! Before the mod, my 3090 FE thermal throttled like always when doing stable diffusion works. Now, It never gets higher than 72 degree Celsius and I can even do batch rendering now ! Even if my room is higher than 30 degree !
Just wanna report back, I did this today! Before I would get 112 C when running OctaneBench, and would thermal throttle. I'm not even mining, but 3D render and gaming (with RT) would make it throttle. Seemed almost like a defect product. Now it stabilized at 86-88 C at 1700 RPM. Approx 25 C reduction. Had some concerns about it, since I have never opened a GPU before. Let alone one that costed me $2000 and took me 4 months to receive. Already sold my previous card, so I wouldn't have any backup if I screwed up either. I've been tinkering with a lot of tech lately though, so I had some confidence it should be fine. Thankfully that was the case. Took my time, used same tool set and thermal pads as you did. Easy knowing exactly which screwdrivers to use, dimensions of thermal pads and where they go when I had the visual reference. Thanks for the tutorial!
Yeah I've said many times that its not just us miners who can benefit from this, but also gamers and anyone doing anything remotely heavy on this freaking card. Enjoy your 3090 FE as it should have been from the start 👌🏻
@@CryptoAtHome Definitely. It really is unbelievable how they cheaped out on something so small in such an expensive card. Barely saw any reviewers mention VRM temps. Baffling oversight from Nvidia for their premium product. Maybe it's not as reported issue because so few people has the card.
It's not a reported issue because until not long ago, there was no way to see the memory junction temperature. This was made available long after release. Also, this problem is really minimal during gameplay which is what most reviewer checked.
hey peyton, question: before the mod did you by chance lose frames while gaming. For me it seems that my 3090 FE runs unnecessarily at max fan speed while playing a simple game like csgo. Then when I play something like Escape From Tarkov, my 3090 sounds like its going to take off. Not sure what it might be but its boiling down to a vram issue.
@@peytonbrandt3943 yeah its pretty odd, I've ran the 3090 FE with a 5950x the past year and the past few months i've been having an issue where if I sat idle on a game my PC would freeze and most of the time I would have to hard power off my PC. After reinstalling drivers, changing power usage to performance etc the issue was 98% remedied. But now when I play CSGO my gpu makes more noise than usual and I even lose frames/throttle when smokes, mollies, nades occur at once. Now with tarkov especially (just loading up) my GPU fans spins extremely fast to where I don't even feel safe playing on the card. I tried to devolt the card as well but reverted that due to instability. I've got an evga 850 platinum PSU with 32 gbs of ram. Not too sure what would randomly cause my card to throttle on any game I play it's starting to get irritating, but I may change thermal padding or get a 1000W PSU. I'll be downloading HWinfo today so I can get an idea if whether my vram chip is reaching 100 C as well, because that may be the overarching issue.
@@ushad Yeah, definitely try out HWinfo first. If that shows VRAM at 110°, then that’s obviously the issue. Don’t waste your money on a 1000w PSU, because 850w is totally fine.
@@peytonbrandt3943 ok so I did some testing and the idle freezing is still here. When running a less intensive game like csgo my 3090 FE runs louder than it should (normally it would be able to run 2-3 heavy title games at once while streaming obs. Now the card has shat itself completely. Now when running a less optimized game like escape from tarkov I would get 100 C right out the gate on the loading screen then in game HWinfo told me my max was 107 C. Do you think I should contact nvidia and begin an rma?
Thank you very much for this tutorial. Before I tried a heatsink and attached a fan, temps were 48core 102 on the memory junction. Now with new pads(same exact ones you used) temp is 51core and 86 memory junction. Running at -200 core/+1000mem 80% power. Could finally turn my fans down from 100% to 70%. Big thanks sir!
Just finished doing this with a repaste and while still stock it’s allowing more power drawing and lower fan speed which helps immensely. Hopefully the links I used from your guide helps your channel out.
i cant get 80mh without my fans sounding like a jet on an FE card i cant put the power higher than 60 without the mem temp at 110. is my card fucked up?
@@CryptoAtHome well I ordered everything I needed so I'll just be waiting that for now. Even when playing games tho I don't get why it is this hot. What if people used it to render videos/3d modeling/ other vram heavy work applications? That takes up alot more time than gaming alone and the card runs this hot by default? Thank you for your guidance with this video. Gonna hope this guy survives a long life.
Games don't have the same workload. It's short (few hours max) and it hammers the gpu core mostly. And this one is well cooled. Video editing is in between but again, you're not editing video for 24/7. On the other hand, mining is all about memory and it will push to the extreme limit, 24/7. Remember, there is a difference between using a lot of ram like video editing and making use of the highest frequency possible like in mining. Now these cards were never sold as mining cards so for gaming and editing, there is nothing to complain about.
This was the best tutorial I found on TH-cam. I placed the Thermal Pads exactly as you did and changed the GPU thermal grease as you mentioned in the description of this video. Before the temperature was 110 c° and now it is 89 running at 120 MH/S. Thank you so much!!
Well done. When I made this video I thought it was too long but I didn't want to cut any part as usually tutorials tend to skip on part they think is not important but some people might find helpful
@@umirza I did the x with dot method but am noticing +20 hot spot temps when under GPU stress loads compared to the GPU temp. I'm going to redo the pads and paste with the spread method.
@@Inboc85 I ended up going spread method based up the recommendation in the thermal paste instructions and its been a night and day difference between stock.
Just done mine and used spread technique very messy but gpu core temp the same as before and hot spot temp 81c memory down from 104c to 84c in bench tests 100% usage
Great tutorial! The PDF was super helpful for me. I mostly do machine learning on my 3090 and I saw about a 10c improvement in memory temps and I was able to bring the fan speed down 30% as well! Thanks very much!
@@CryptoAtHome Your video was excellent too, I wouldn't have figured it out my myself. Also in regards to your comment at the end about swapping out the pads again for Fujipoly thermal pads, did you ever do that? I'm not sure if it's worth it. I think the VRAM chips are rated for like 100c to be in spec. So you may see lower temps by doing the swap but I'm not sure you will see a performance or a lifespan improvement by doing that and it would be extremely expensive. But I would still be interested to see what the thermal improvement is (if any).
Thanks. Nah, I didn't try. Fujipoly pads are way overpriced and I doubt the difference in (maybe) slightly lower temps makes up for it. Plus its a one-time use pads as they're really brittle. All-in-all, the best choice seems to be the Gelid Extreme so far.
Great video. With stock pads I can mine at 116 Mh/s with GPU memory temp at a constant 106 degrees. Massively better than what you were getting but still makes me nervous, especially when thinking long term. Waiting on the same pads from aliexpress to arrive before making the same thermal pad change. This video gives me much greater confidence in doing it. 👍
Hi, thanks. I doubt you will see such massive change in your case as you had pretty good results. Theoretically 106 degrees is ok-ish as GDDR6X is rated up to 120°C and Nvidia deems it safe up to 110 degrees. But yeah once the summer is here and the heats goes up, it will probably reach the dreaded 110°C.
@@CryptoAtHome Exactly my thoughts. PC in man cave/garage where I keep the heating off when mining, so largely same temp as outdoors. Gets very hot in there in the summer so will be a different story then I suspect.
@@doitdeluxx I was hitting 112mhs with stock pads but bouncing off of 110C. I used slightly worse pads than these when I did this a month ago, only did the backplate, and now I hit 120mhs stable and don't go over 102c. If I take it back down to only get 110-112mhs I can keep temps under 100 after just the backplate and 11w/mk pads.
@@CryptoAtHome GDDRX data sheet on Micron shows operating temps between 0 to 95C (in.micron.com/products/ultra-bandwidth-solutions/gddr6x/part-catalog/mt61k256m32je-21). Long term 105C - 110C will have an impact on the VRAMs.
Thanks so much for this, just followed it using exactly the parts and tools you used (I looked for the 17W/mK from fujipoly and alphacool but they're much more expensive or out of stock, or both). I was running at 60% power limit an -502 on both core and memory (using afterburner) to get about 71MH and 95*C. Now on the same settings it's giving me 76MH at 80*C. So only a 16*C drop for me but I was about 75*C off ambient (assuming 20*C room temp) not 90*C so I wouldn't expect to get as much. I also replaced the thermal paste with what I had left over from my Noctua NH-D15 so that may be transferring a bit more heat and reducing the improvement in memory temps a little. Hopefully now my 3090 FE can pay itself off a bit quicker and last well, thanks! :D Edit: Now up at 95*C again which is as hot as I want it getting, that's at 80% power limit, -200 core clock, and +1000 memory clock, giving 115MH. That's a 62% improvement at same temperature and I've got some fine tuning to do yet fiddling around with clock speeds and maybe power limit up for down very slightly, so may squeeze just a little more out of it without breaking 95*C. Awesome improvement!
Yeah fujipoly pads are way overpriced unfortunately. And that will add to the cost so your ROI will be longer :/ Pretty cool improvements imo, even with "only 16°C" drop. I'd say that's very good already ;)
Just did this now to my 3090fe! I repasted the core and used the thermal pads you recommended, and my temps went from 65c -> 61c on the core and 104c -> 82c on the memory! I was really nervous at first but thanks to your guide, my card is now better than ever! 👍👍
Just wanted to thank you for this guide. I used this video to do the same mod to my Founder's Edition 3090 today, and did indeed see 20-25 degree drops in vram temps. Instead of undervolting, I can now overclock and keep the vram at a max of 90 degrees. Truly stunning that Nvidia released these cards in this state.
I just completed this by following your direction I really liked that you put the dimensions for the thermal paste that you cut. That by itself was very helpful! The only thing I did was also change my GPU thermal paste to Artic MX-5. Also I saw drastic drops in my memory junction. With my case closed while mining I'd hit 102 to 104. If I open my case and have a blower style fan blowing at the 3090 with a heat sink and a noctua 120 mm fan blowing on the heat sink I'd get 94 to 98. But now I get 84..with my case closed I get 88. Very happy with the results and your help thank you!
Thanks for the tutorial. Totally recommended. It took me a few hours (I was doing it slowly step by step) and some planning with the cutting templates but everything worked flawlessly and temps down about 15-20º. I also cleaned and applied NT-H1 to the GPU. I don't understand why nvidia used this low quality pads...
@@intech7863 Do you mean memory pads @ 1,5mm is not right? Didn't have any problem with them so far. GPU die temps was at least -5º I know because I took screenshots before and after in same scenario, time and configuration. But the test was minning eth not gaming.
@@jaimito061 1.5 is right just some vram pads size is wrong example V pads and pci-e pads on both side gpu and backplate must be cut perfect.And left strip pad on die side must be cut less wide then the this video .Since you not gaming no problem at all
@@ДенисВладимирович-с9ц from one forum i just paste here . -Hi, after doing the pad mod, the junction temp is good at max 84 C, but my cpu temps are more than 10C higher than before while my score in port Royal is lower. Is that normal? I first thought of to little paste on the gpu (see picture) and repasted with lots of mx4 in a cross. Makes no difference. ANSWER!! What thermal pads did you use on the GPU Core side? Those thermal pads are either too thick or too hard (not squishy enough). Are those 1.5mm pads? If those are thermalright pads, on the core side, try manually compressing them down about 0.3mm with a piece of glass on a flat, clean surface (do all of them together at once so the compression is identical. You will have to trim them again to size when you're done (especially the VRM pad at the top). If this ends up not working, try Gelid Extreme 1.5mm pads. Two other problems. 1) the VRM pad at the top is much too wide. It's covering small SMD rectangular caps next to the VRM's that sit higher than the VRM's. Trim that down so that those small SMD caps are not covered up. You can trim it after doing the compression I mentioned 2) the single chip VRAM pad on the left side is too large. This pad, if it's larger than the VRAM chip itself, will interfere with the edge of the heatsink. There is literally no room for error here. After you do the compression of all the pads, make sure you manually cut that so it's the exact same size as the VRAM chip and no larger! Do the same trim for the backplate single chip VRAM pad also. Or just swap out the pads for Gelid Extreme 1.5mm pads (and remember to trim the VRM strip pad perfectly and the single chip VRAM pads!) --Hi, I used Thermalright 1,5mm pads. Will try to make the pads fit the vram exactly, although the original pads are a lot bigger than the VRAM, as well. Thank you. --ANSWER!! The original pads are -extremely- squishy, far more squishy than any pad you can buy normally. They are more like some sort of putty or phase change material than an actual pad. So the tolerance for compression is extremely lenient. It is also this problem that makes aftermarket pads so tricky, to maintain the correct contact pressure on the core. From looking at people's tear-downs, it looks like the original pads compress by about 0.3mm (1.5mm to 1.2mm). But on the GPU core side, the thermalright pads only seem to maybe compress 0.1mm after mounting, and then there are not enough screws to make it compress more. And I think 1mm pads are too thin (no one has tested this on 3090 FE). The only screws that attach the PCB to the heatsink are the four GPU Leaf spring screws! Nothing more. This is a big problem. So you screw the leaf spring in down, to the end, but the pressure downwards is not enough. And there are no screws around the VRAM to help. The screws at the edge of the PCB (Backplate, Torx/philips) are useless for mounting pressure! Compare any AMD reference video card (r9 290X, Vega, etc). There are screws all over the PCB! And they screw the PCB into the heatsink. like 8 screws, not including the X-bracket! Then for Vega 64, six more screws for the backplate, hah!
Just completed replacing the thermal pads on my RTX 3090 FE. What difference! I'm now mining @ 121 MH/s with a GPU temp of 58, fan @ 75% and VRAM temp of 94. Thank you for this amazing step-by-step guide.
Not in the video but in the description, in the pinned comment and in at least one hundred replies to comments :D I almost want to reupload the damn thing to include a repaste haha.
Thanks for making this guide, after a rather stressful five and a half hours of really taking my time and working out every step one by one I was able to do the mod and have seen some of the best gains yet coming from the worst temperatures I had only seen reported by one other person. I don't mine but I do mostly 3D render and occasionally game so I really needed to do this, the highest I saw before the mod was 112 degrees which is crazy and I think that must have been with the stock fan curve as when I did another lot of testing before the mod yesterday I only got as high as 106 with a custom fan curve I set. Well now I've seen it get as high as just 82-84 degrees under rendering load which is crazy, that's almost a 30 degree drop compared to the worst temperatures I saw so I'm very happy. I did of course repaste it too and I used Arctic's new MX-5 with the spread method as it's nearly impossible to get TF8 or TFX in more than 2g tubes and there have been too many people reporting dried up tubes for me to justify potentially wasting £12 on a tube, a 20g tube of MX-5 is £22 which I bought to repaste a few things and turned out to be a good call as I had to clean off the paste from the die twice due to mistakes. You know what though the MX-5 is actually really good, it's got a higher density to it than MX-4 which someone on reddit had used on theirs and reported that their temps had not changed which is almost the same case with me, I actually saw some minor gains on the core temp, only by about 1-2 degrees max of a difference when rendering but I think that the TF8 or TFX really aren't the absolute only ones you can use. The only minor concern I see is that the backplate appears to be slightly bowed up in the middle and upon inspection of the stock pads under it when I first took it off they appear to be 1mm rather than 1.5mm but they weren't all making full contact with the chips. I think perhaps it's possible that the 1.5mm pads need to be rolled out a little to be around 1.25mm for the bowing to not happen. While I am very pleased with my gains I cannot help but be a bit concerned about the thickness of the pads on the memory chips causing other areas under the backplate to not be getting the full amount of contact they need so I might be losing some performance there. Overall it was an excellent result and as long as you take your time and don't rush things it'll go well. Also I used simple masking tape to pull off the little screw caps, you don't need anything stickier than that really. I also used little strips of it to hold the wires back so I had an easy time of getting the PCB back in, you don't need to use any tape sticker than that or you could end up tearing a cable trying to get it off.
Five and a half hour, boy did you take your time. Must have been the five longest hours of your life :D Well at the results are there, glad it all worked out. And yeah MX5 or 4 is a perfectly good choice, no need to rush and buy TFX or TF8. Enjoy !
@@CryptoAtHome What do you think about the issue with the bowing backplate? I think there could potentially be some performance loss if it's being pushed up in the middle by the memory chips pads.
I can't really say. I haven't noticed this bowing from my side but I can tell you that me and a lot of others have done this mod this way and its been flawless so far. All that with mining 24/7 so I don't think you have much to worry in your case. Also I wouldn't advise mix-n-match but if really you feel insecure about this, try it like this first and then you can always change the pads with 1.5 gelid pads which are softer and will squish unlike the thermalright pads.
I came from a forum where we are all fighting this problem together. Thank you very much for taking the trouble and clearly demonstrating all the stages of replacing thermal pads and giving advice. But why didn't you remove the old thermal paste and replace it with a new one? :)
Simple answer: I was still waiting for the paste to arrive and couldn't wait any longer :). In general GPU temps seem good anyway. But I haven't tried in gaming, which would push the core. Over just a few months, I went from my old 1070 to a 3070 FE to a Gigabyte Eagle 3080 to a 3090 FE. I've had the card only for a few weeks and as I said in another video, I'm a Tech Lead and don't find myself with enough time to play anything really.
Awesome tutorial. Made yesterday for my 3090 FE. I'm not a miner but I was facing FPS drops + 110 °C VRAMs OCCT Stress Test GPU = Stable @ 68 °C with FANs @ firmware RPM (Maybe 30% or 40% RPM) Tips for FAN connectors: Use a credit card to push the connector horizontally when connecting back. VRAMs decrease of 20°C is real with 1.5 mm pads. Used Arctic MX-6 for GPU. --- My 3090 FE was brand new when I bought it last year, I discovered that the cold plate was scratched (Thank you Nvidia for the quality control). Original pads were sticky + kind of fiber inside. Used Isopropanol 99,9% to wipe everything (and patience).
Thank you so much for the awesome tutorial. I followed your guide and did it myself, but unfortunately, I see hardly any improvement regarding VRAM temp. I am looking for a root cause and currently my interpretation is that the 1.5 mm Thermalright pads may be to slim for my card. Did you consider using 2 mm thermal pads? Why 1.5 mm?
No don't go for 2mm, you will have terrible contact. Some people are reporting better success with 1.5mm Gelid Extreme which are softer than thermalright pads.
Hi, thanks for your video. Work on my FE too. close case PL 78 OC mem : 350mhz fan : 78% auto T°: 100/102 Now : PL : 85 Oc Mem : 1200mhz fan : 55% T° : 88/90° yeah :D

Thanks for the video. Just to share my experience I only replaced the thermal pads on the front pcb (the easy side without the gpu) and it improves temps, but you'll still see throttling when mining. I can get around 95-105MH/s now using -90 Core, +950 memory, 90% power limit, 80% fan 1 and 50% fan 2. I can get about 116MH/s when fans are on max and monitors are off. Fan 1 speed makes the most significant difference on hashrates. Your case cooling will also determine whether or not you can sustain this rate and your hashrates will vary. I realize only doing one side wasn't the scope of this, but if anyone else considers only replacing one side you will still get throttling albeit with better speed so I'd consider it worthwhile.
@@MatthewTheCaveman Sorry don't really have the data cause the before was so abysmal I didn't bother. I'd assume that if full pad replacements are giving people -20C then replacing just the top side will be about -10C. It's obviously not that 1:1 but it's enough to improve hashrate performance over a long period of time and also stop it from throttling in games. Playing Hunt Showdown in 1440p at 162fps I max at 100C now at 114% power limit.
Yes, I think we saw the same information. Someone said, and I quote, "That isn't dry paste, it's a phase-change TIM tape after it's melted/set into place. Most machine-assembled sinks that need a really high W/mK use it because it's a convenient form for automation and as efficient as paste."
Thank you for making this video. My RTX 3090 FE has been on the loud side since I got it but for some reason Days Gone was really making the fans take off even though my GPU was only at 64 degrees. I checked the memory temperature because of this and it was topping at 104 degrees. I followed your video to replace the pads and also reapplied thermal grease. Now during the same game, the memory is topping out at 90 degrees (A 14 degree drop) plus it is much quieter now.
Thank you for making this video. I applied the pads and technique you did to my 3090 FE. I also applied Thermal Grizzly Kryonaut to the GPU Core. I'm seeing about a 14-16 deg C temperature drop. The best part is that the GPU fans don't have to run as high anymore. It was very noisy before and now...so silent!.
Followed your link and had the video rewinded multiple times but everything went smooth with major temperature drop. I was hitting 108 in gaming max now max is 68 degrees. Mining is great too now I’m new to that but it’s obviously helped ALOT
Just spent the last 2 hours doing this to my 3090 FE. Thank you very much for putting this together. The measurements you provided for the pads were extremely helpful and saved me a bunch of time.
Nice! I am getting the same results after replacing my thermal pads. I got my vram temps down to 82c at 100Mh/s on 3090 . I also put aluminum heat sinks attached with thermal pad on top of card with fan blowing over it. It definitely helped by 4 deg c.
Thanks for the video - extremely helpful, especially the dimensions… saw an immediate difference in temps! Anyone else notice that the old pads were really greasy? Serious pain in the rear to clean all that up…
Followed the video and added the same thermal pads. Wow 22 degree drop. Thanks Nvidia. I was using an extra 360mm radiator with a thermal pad for an 8 degree drop prior. Now it looks cool again and runs cool. Thank you so much for this video
I already had active cooling with heatsinks on the back and a NF-A12 pushing on them. Best result was 92C at 100% fans. I've just done both sides following your vid and I'm now at 82C with my fans at 75%. Also really enjoyed the teardown! Can't thank you enough! 😁
Cool :). It's funny though, when I did this video, I thought it would be viewed by only a few people. I didn't expect 20k people wanting to mod their card.
@@CryptoAtHome ngl I was so game to rip it open, and those temps had me seriously worried! Props man, congrats on the views (and for fixing Nvidia's bad design) FYI, down to 78C at 100% fans
Awesome video. Just ordered the pads. Got the 3090 FE last thuesday and have been mining now for almost 24 hours. I didn't have to lower the memory speed and am currently getting 104C max @ 107 MH/s. Still too high for my liking, so I'll use this video as a reference for when the pads arrive. Thanks a lot! WIll add my temp difference to this comment when I've done it
Just want to give you a shout out! My card would hit 110C on memory temp right away at stock settings. I also replaced thermal paste. Now it is mining without a problem and the highest I have got on the temp is 96 C while pushing it to 121 MH/s. Good work my friend!
Many thanks for this guide, i have successfully made the changes to the thermal pads and i am also getting -25 degrees. Everyone should do this! Couple of things to note; when pulling the PCB away make sure you prise it from one end as my GPU was really cemented to the cooling block and trying to pull the PCB away level wouldnt break the existing GPU thermal pad it just kept lifting the whole cooling system (first time poking round in a gpu so i was very scared of breaking it) You will need to reapply thermal paste but make sure it doesn't conduct electric (some do) Happy happy happy. GG
@@CryptoAtHome might of spoke soon, getting alot of instability now, currently trying to troubleshoot but even dropping my 3090 down to the settings I had it on before I modded the thermal pads is resulting in crashes. I had it mining at 90% power, +1000 MC, +100 cc, mem junc temp= 84-86 degrees C @ 122mh/s along side a 3070 at 50% power +1200mc, -500cc @ 62mh/s for 2 hours then it crashed. It then started crashing more often even when I reduced the 3090 settings back to 60% power +600mc -100cc which I had previously had the card running at with the 3070 for days without a problem 🤔 At the moment I can't figure out if it is a coincidence. Any ideas?🙏
@@kylee3084 Hmm not many ideas no :/. I've been running the modded card 24/7 since I did the mod more than one month ago now and it's been rock stable. Maybe one of the pads slipped when you turned the card and this particular memory chip is overheating causing the crash? 🤔
I did my 3090 FE today and it's been a total success. Thank you! I only use my GPU for 3D Rendering and If I run the redshift vulture benchmark about 3 times in a row I would blow past 100 degrees easy and I would just stop running it, I'm sure I would have eventually gotten to 110 degrees. I don't know After the pad install I get mostly 86 degrees. Wonderful! Just a couple of tips I discovered that might help. A. Take off the cover to the sli bridge cover thing on the PCB. It makes it easier to remove and reinstall the backplate. B, True the old pads are sticky but a plastic pry tool removes them quite easily. C. As another poster on here said, use scotch tape to hold the wires back during reassembly. So easy. I used thermal grizzly kryonaut and I seem to be getting better temps on the GPU as well.. it was really a problem before but the less things heating up the better. The LED light cable really is a nuisance. I wish I had a tip that would help with that but it really is a pain in the ass. The good news is that actually goes back in quite easy during reassembly. Thanks again for saving our cards CryptoAtHome. :) Super excited to start rendering again.
Nice ! Yes the led cable is a pain but that's why I shared an "easy" way on my other video. "The less things heating up the better". Well that's technically not correct. The heat produced by the gpu core, vram and vrm is the same. You're just improving heat conductivity/dissipation ;)
@@CryptoAtHome Haha.. I probably would have better said, the less things catching on fire the better. ;) I saw your other vid on the led, mine was still so snug in there that when it finally lifted out I swore it broke... All good though. Thanks again man! Hope your channel does well, look forward to more content.
Thanks, I appreciate it. I have another motherboard review coming up and then I need to come up with interesting videos . I'll see where my imagination takes me :)
Dude this mod is amazing! Did it last night and the results were insane and exactly as advertised! Thanks so much for making this vid! Shared results with a few discords I'm in and hopefully you'll get more views/subs. Pre mod: my best numbers were 110mh/s 96c mem 100% fan. Post mod: 123mh/s 80c mem 70% fan. Definitely a must if you're a 3090FE owner!
@@CryptoAtHome BTW, I attempted to buy the pads from your affiliate link but it took me to Amazon.fr and I am in US. I had to just search and buy them myself... If you can get/provide US affiliate links as well I'm sure you'll get more referrals. Also the LED cable was tough to get out even with the second vid. I had to lift it up and slightly to the left. Came out easy once I found the correct angle, if that helps anyone else.
I don't remember having to lift left but maybe this depends. Hopefully this helps some other people, thanks for the tips. And thanks for the affiliate link idea but I actually make no money from this :) I tried 3 times already to get in but once I reach the required limit, Amazon just closes my account and drops all earnings. Apparently I'm "too small"... But I'll keep trying. Maybe if I try Amazon US I'll get in 🤔
Thank you, I was getting a peak junction temp of 106c while playing Control with the fans maxed out at 2400rpm even though I had undervolted the card. It was the first time I had taken a card apart and I was a little nervous but I followed your video and hey presto! I have removed the undervolt and am now getting a peak temp of 94c and the peak fan speed of 1365rpm. My card is so much quieter now and I even feel I have the ability to push it a little.
@@intech7863 i heard the thermal pads were improved in the early part of the year, so I guess it depends when you got your 3090FE. I originally noticed the problem in warzone, but an undervolt sorted that out. However in control with everything turned up including ray tracing the peak junction temp were bad and the card was so loud. No issues now I replaced and 94c peak junction is fine, they cool a little once the fans ramp up a bit. It was always about the noise anyway and now the card is quiet, except for the coil whine.
@@curtismariani6303 i got the gpu 6 of june.Just install control but need more test on 1440p 94c memory but will try everything on max to see what will happen. Also more agresive fan curve improve temps. About coil whine i have a little i fix it by install 2 120mm fan braket below gpu at 1000rmp thats how coil whine is gone
Heya, thanks for the sub. I'm glad this helped you out. I just wish we all didn't have to lose time and money for something Nvidia could have done from the beginning...
Fantastic, great video, thanks. Mine was maxed at about 105MH/s (with the memory jn temp at 110)... I throttled it back (so I didn't cook my card) and was getting 100MH/s at 102 degC. After the mod, I'm running 122MH/s at 96 degC with the fans at 50% (20% lower than before). Afterburner set at Core -500MHz, Memory +1400MHz, Power Limit 90%. Quieter, faster, cooler. PC (monitor off) running at about 375W. Damn good, awesome. Poor that NVidia didn't do it!
Great video very informative and the dimensions to cut the pads saves a lot of time. I followed this in about 2.5 hrs and was able to assemble everything back together. I ended up also re applying the thermal paste with TF4. This easily knocked 15-18 C off my running temperature. I do not feel like my card is going to burst into flames. I would also recommend four pad packages as you can be a little less tactical with your cuts. Good job and good video!
Thanks, yes I saw people sharing the pictures of their thermal pad applied but nobody gives the dimensions so you're left on your own. I thought it would be helpful :) Thermalright Odyssey is pretty cheap so you can go with four pads and it won't ruin you. Enjoy!
@@CryptoAtHome Just an FYI you're missing one of the width measurement for the front of the PCB. It wasn't hard to infer what it should be. Also falkentyne posted that removing the NvLink cover before putting the backplate back on allows for more pressure to be applied to the memory modules. I removed mine and so didn't do any before or after measurements but it doesn't hurt to remove it and then reinstall once the backplate is back on.
Yeah I know about the width but I didn't know where to put it and assumed people would be able to infer as you did :) I saw his comment on Reddit but I'm not sure I want to remove it and risk losing it. I have a damn cat that snatches everything.
Fantastic video! My 3090 FE was struggling. I tried to keep it at 100C or below, but had to run low clocks and high fan speed just to get a hashrate around 100mh/s. Now, with these thermal pad mods, it is like a completely different card. I am running at a 90 PL, 1300 Mem Clock, -502 Core Clock, and a nice low 70% fan - and temps are sitting at a comfortable 88C and the hashrate sits around 123 mh/s. That said, I have tested higher OC settings keeping temps under 96C and managed over 126 mh/s and am confident I could go higher - I just don't want to throw to much wattage through the card.
@@CryptoAtHome Thanks for the tip. I have no plans to run it beyond my current settings (at 123 mh/s). I was just pointing out that it could handle the higher setting without overheating during a short test. The new thermal pads work great!
WOW, Till now, the longest and most detailed Video about Thermal pads on this card, thank you for that !!!!! i will try to do exactly the same by my 3090fe. Pray to god i will made it and it will work. Greetings
@@CryptoAtHome Yes, exactly the same, but i still have 100c on memory junction. I believe, this card isnt for mining yet. Yesterday i bought a 3070fe. No problem, runs on 70c with 63 mh. will buy more of them ;) the 3090 i will resale
I did this today. Before I was at 40 hash rate and 94 VRM. Anything over was 110 degrees on VRM. Now I'm at 88 VRM at 100% power and 111 hash. Not to mentions gaming performance is so much better. THANK YOU!
Heya. VRAM, not VRM, that's a different thing. Nice, you've got much better result but you shouldn't be at 100% power limit. You should lower it to around 90 and decrease the core overclock to -500. Consider subscribing to help me out :)
I replaced the pads today and my temps dropped as well by 20deg. But my gpu temp raised by 5. It's still better to have a gpu at 50deg than vram at over 100. Thanks for the video
Hi mate. I've done the mod on Sunday and tested the card until today. Everything works spot on, while before I couldn't even go to 95mhs without the card go to 100°, now I'm mining at 115mhs and the I get 81.5 median value over the last 3 days. Also this period is the hottest time it's been here in UK so I suspect on colder days the temps will be even better. My settings now are -200 core, +750 mems, 80% power limit, 70% fan speed. I couldn't see any increase to gpu temps, I used TF8 Thermaright paste and done the X and 4 dots. The cables were tricky but managed just fine with some clippers (for the led one). I used the pdf with the pads layout and there's one small issue there, the pads that had a diagonal (the 2 that are not rectangular shape) should be mirrored. The way they are now will end up with the sticky part on top so if you place the pads on the card itself it won't be ideal. Thanks a lot for the tutorial and goodluck to everyone who attempts this mod.
Yeah it's getting hot everywhere ( we're at 29°C here in Paris today) so our precious cards are gonna suffer. Good timing for doing the mod. As for the pdf layout, thanks for pointing that out. Unfortunately it's not mine. I provided the dimensions in the video and somebody made the pdf template afterwards, which I linked and credited.
@@CryptoAtHome Maybe I cut the pads on the wrong side. I cut them with the transparent face up so the pads should be ok if we cut with the blue part up. Anyway great job with the tutorial. One more thing that could help someone. When I assembled back one of the pads that is close to the bottom part of the card was actually obstructing the backplat to fully close so I had to open and trimm it a bit. If someone closes the backplate without checking for that could end up with temps that don't drop as much.
Awesome tutorial. Thank you! I just did this to mine and my memory temperatures are down 15-20C. Some additional tips:
* After you detach the cables, it helps a lot to use a few pieces of tape to hold them back and keep them out of the way.
* Don't try to cut the thermal pad with scissors - it squashes the edges. Just use a knife and ruler, it's easier.
* The thermal pad has a smooth side with clear plastic, and a rough side with blue plastic. The smooth side is stickier, and you want to put this side down on whatever surface you're placing the pads on. Remove the clear plastic before applying the pads. You can leave the blue plastic on until you reassemble, to avoid getting dust and fingerprints on that side.
* I drew the pieces out on paper before cutting to make sure everything would fit within the 85x45mm pad dimensions. I used 3 pads and had a little left over.
* All the pieces are symmetric, except for the two with diagonals. Make sure you cut the diagonal pieces the right way round! I did them backwards so I had the rough side facing down, and they fell off during reassembly.
* I repasted the GPU with Noctua NT-H1. To my surprise, GPU temps actually increased from ~65C before the mod to ~75C. I think this is because the GPU is no longer throttling on mem temps and can run at higher load (this is reflected in higher overall power use and GPU clocks), and the fans are also running more slowly than before. My fans used to run at 2700rpm constantly when the card was under load, but now they run at around 1400-1500rpm, so the GPU isn't being cooled as much. If I force them to run at 2700rpm using Afterburner, my GPU temps fall back to slightly less than before the mod, which is now I know the repaste was successful.
Nice tips. We need more people "liking" your comment so it goes to the top.
@@CryptoAtHome I'm curious about your GPU temps at idle and under load. It looks like your GPU is at 37C while mining, which seems amazingly low - mine is at 35C just idle and hits 75C mining. What’s the ambient temperature in the room, and do you have any additional heatsinks or fans on the card? My ambient is around 25C and I have a 2070 Super installed underneath which may be limiting airflow...
Right now it's getting hotter here and all the mining rigs are generating a ton of heat in my apartment which I'm having a very hard time evacuating.
With current ambient temp and a whole mining rig nearby, I'm at 38 degrees idle for the gpu temp and 52 mining. I have 5 Noctua NF-A12 pulling and pushing air in the case at a constant high speed and the side of the case is open.
75 seems pretty high though. Was you gpu thermal paste really dry ? Did you change it ? Also , did you lower the gpu core speed to the minimum ? (-500 in Afterburner). Did you lower the power limit to maximum of 90 (or lower)?
I had a small heatsink which I removed after doing the mod and I have one extra fan that is pushing air from the open side right onto the backplate.
@@CryptoAtHome Thanks for the additional information! I'm pretty sure the culprit was having the 2nd GPU below it, limiting airflow and increasing air intake temps for the 3090. With the 2nd GPU removed, my GPU temp is 54C when mining using the same settings as you (80% power, -502 core, +1056 mem, 70% fan). The remaining 2C is probably because I have the case closed vs yours open, and your extra fan. I'll have to improve my cooling for dual GPU or mount the 2nd GPU externally, or go water. For now I'm going to put some heatsinks and a fan on the 3090 backplate, and add a side fan to get more air between the two GPUs.
The original GPU thermal paste was completely dry and I repasted with NT-H1.
Cool. Yes I suggest getting the second card out of there. If you check my video "DIY mining rigs", I actually did exactly that when I started mining.
The balls on this man for not only tinkering with a hard-to-find 3090 but actually improving it! We salute you
Guys, if your gpu temps went up after this mod, its because original gpu side thermal pads are softer and thinner then Thermalright 1.5mm. So the heatsink doesn't have such a tight contact with gpu as with original pads. It has nothing to do with throttling or low frequencies. I would recommend to flatten Thermalright pads little bit for gpu side or use softer pads like Gelid Extremes. Also repaste gpu, use twice more thermal paste then you usually apply for cpu.
Since I want to reduce the overall VRAM temp and fan speed on my 3090 FE, I consider to try this mod out.
Would you recommend using 1mm thermal pads for all parts instead of the 1.5mm pads?
Great video, thank you! I did this on my hottest running card and it went to become the coolest one, very happy!
A few minor things:
1) The 4 torx screws holding the GPU chip are size 6, not 5.
2) The little magnetic screw caps are labeled D, E, F, G on the inside: They go on this way:
F----------------D\. /
RTX 3090 X
G----------------E/. \
3) Two of the 120x120mm pads will cover three cards
Cheers!
Yeah you're correct it's Torx 6. I corrected this on my video for 3080 FE. Thanks for the additional tips 👍🏻
@@CryptoAtHome I also stuck a few little aluminum heatsinks on the backplate which -- while it's not pretty -- reduced the memory temperature even further
Well pretty doesn't bring extra performance so go for it !
Thx for the video and comment; btw I've succeeded to repad using only one 120 x 120 mm.
what paste did you use on the GPU die?
Brilliant tutorial and the sizes were a huge help. If anyone is in doubt about doing this, just go ahead and do it. The only thing to really be careful of is the small wires, the rest of it is easy.
My results with mining after 25 minutes with no over/under clocks:
Before swapping pads -
Memory temp - 112 Degrees
Core temp - 55 Degrees
Hashrate - 99-101 MH/s
Power Usage - ~262W
Gelid Extreme 2mm pads-
Memory temp - 94 Degrees
Core temp - 62 Degrees
Hashrate - 107-108 MH/s
Power Usage - ~339W
Extreme Odyssey 1.5mm pads-
Memory temp - 89 Degrees
Core temp - 63 Degrees
Hashrate - 108-109 MH/s
Power Usage - ~340W
Also getting about a 7-8% fps boost in Cyberpunk on max settings. I think what was happening before was my GPU was throttling based on the memory temps which is why the power usage was so low at ~262W. I think this also explains why the core temp is higher because of the higher power usage. Also I wasn't very comfortable leaving my card mining sitting at 110+ Degrees but 89 is totally fine.
I would like to try the Gelid Ultimate pads though with their claimed 15 W/mK heat conductivity compared to the Gelid extreme's 12 W/mK and the Extreme Odyssey's 12.8 W/mK. But I can't find the Gelid ultimate anywhere in the UK
If anyone from Nvidia sees this video your thermal pads are garbage and come off like old chewing gum with some silly mesh fabric on them. Cut that shit out Nvidia
Thanks, nice results. As for Gelid, I'm not convinced the higher model would make a meaningful difference. Maybe if one goes for the Fujipoly at 17 W/mK
Thanks for putting this video guide together. It was incredibly helpful and I can attest to a 20-25 C decrease in the thermal junction temperature.
Welcome to the club :)
My thermal pads finally came in. OMG. 20c is NO JOKE. Use cutlist to optimize cuts. Amazing. Thank you!
Dude, what a concise, well made freaking video. Just finished and can confirm that I'm seeing a 20c drop. Amazing. Thank you!
Thanks, I just wish I didn't mess up the cables part in this vid 😅
Happy mining (or gaming) !
I saw your news on notebookcheck, and my god, you're jst a small youtuber, yet you found a solution to reduce the heat of the rtx 3090 is very impressive, btw great tutorial vid
Haha thanks. Not sure what does being a small or a big youtuber changes though. If I'm a small youtuber who works as a Tech Lead in life and there is someone else which has 100 times more subscriber and delivers pizza, who would you trust more ? ;)
@@CryptoAtHome Well said!
Love the thoroughness of this video. I am a bit shocked that you didn’t re-paste the GPU itself. I have always done this on my cards. The NVidia thermal paste is pretty terrible just like their pads. Nice job again.
Dude thank you so much for the in-depth tutorial. I followed it exactly as you explained and I am seeing the exact same improvements on my 3090. This video gave me the complete confidence to take apart a $1500 GPU and it worked perfectly! This was literally my first time taking apart a GPU haha
Nice. The 3090 FE is thankfully not so hard to take apart and doesn't use glue. Enjoy your new temps
How is the temp now ? The card is good ?
Yup still holding up no issues 👍
Which pads did you use? Also 2mm or 1.5mm?
@@icephoenix3565 You have to use 1.5mm. 2mm won't work. Jayztwocentz just did a video on this as well.
Thank you for the detailed process i did this because my 3090FE kept having fan Reving issues so bought the Kryptonite pads but that didn't fix it so bought 4 packs of 1.5mm pads some thermal Grizzly bubble gum and reapplied much better no more desktop crashes and hot spot sitting at a cool 54c while gaming.
thank you for the detailed guide. been debating about doing this on my 3090 fe since i got it on launch. finally bought the thermal pads and used your guide as a step by step guide.
Nice, I hope you're satisfied with the result.
Excellent tutorial, I've just done this to my 3090 FE and seeing 20-25C decrease in thermal junction temperature also. Now able to drop fan and getting: 95C TJT 56C GPU @ 55% Fan - 121MH/s
OC SETTING PLZ
Just wanted to say thank you for the video. Did my thermal pads and thermal paste and ran the miner for about 6 min... Thermal junctions from 104-106 at 100% fan speed to.... 84 on the thermal junction with fans at 80%! Wasn't the the easiest thing to do when you look at the cost of the card but my only regret is not doing it sooner!
My only regret is having to do this at all!
Fantastic video. I needed a video with this level of detail before trying it myself, and I'm happy to say I brought my memory temps down from 102c with a memory downclock to 88c with a modest overclock. Thanks!!
Thanks :)
I decided to make this video because I couldn't find a comprehensive guide and data on Reddit was all over the place.
Thank you so much for this - I have great airflow in my case but Final Fantasy 14 still hit around 104 flippin degrees on the memory in HWmonitor with very noticeable fan noise.
I did the mod precisely as instructed and now it seems to be at 86 with INAUDIBLE fans (on my custom curve in afterburner). You're awesome for this.
Best video I have seen on this subject! The dimensions are super helpful.
Thanks, glad it's helpful :)
Nice. Thankfully, once everything is explained properly, this card is not so hard to take apart, even for a novice. Enjoy !
Love those dimensions they are fantastic
I’m a newbie and it was my first time ever taking apart a graphic card. I was able to get take it apart, take off the old thermal paste and pad, clean it, and reapply the new thermal pad and paste, and put it back together in 3 hours. I think I strip one of the magnet screw but it works. Drop the temperature from 105c to 90c for mining. Man that was scary and I thought I broke it 😂 thank you very much and very informative and on point.
Glad it worked out. Yes the first time it's quite scary to take apart such an expensive card.
Totally works! -20 deg C (or more!). I used the exact recommended thermal pad brand and size. 3 packages is plenty.
Thanks for the detailed measurements of the thermal pad cut size. That saved me at least 30 mins of tediousness.
I just can't believe it works so well! Even as I was putting the pads in, I'm thinking... there's no way this will help much.
I was mining for 1 week on my stock 3090 FE. I could barely run +300 Memory. I was at 108C with lowered core(-150) and power at (82), fan at max. Getting 108Mh on NiceHash QM.
Now I'm running +1350 Memory, Fan speed lowered to 65, with 88 deg C temps. 120 Mh!
As some extra help, I use 2 oem CPU heatsinks (with the fans removed because of space) on top of the backplate. This helps remove another 2 - 4 degree C.
Thanks again, great video!
Yeah I think we're all suprised how bad the original thermal dissipation is and how much better it is after replacing the pad with some cheap aftermarket ones. Enjoy your modded 3090 FE!
I got my RTX 3090 FE and haven't used it for over a year before finally putting it into my rig. It was a barely used unit anyway, it didn't even have the firmware update for resizable BAR installed when I got it. I heard about this problem but haven't looked into it until now. MSI Afterburner reported a thermal limit on the OSD when playing a game and it surprised me because the core was around 70C. I don't usually use the OSD because it can cause issues, but I'm glad I did. I loaded up AIDA64 only to find the VRAM was maxed out at 110C. I'm glad this doesn't look too difficult so I will definitely be trying it, along with using my Alphacool Apex thermal grease for the core. Probably easier than redoing the thermal paste on my laptop by the looks of things as far as disassembly. Thank you so much for making this video.
Another success story for me too: from 104 to 86 degrees. Another piece of advice for people doing this mod; I read on the original overclock thread that someone had good results just replacing the pads on the top of the PCB. I tried just replacing the top pads and only saw about 2-4 degrees difference. My advice is just do the whole PCB, even though the underside is daunting.
As far as I've seen, the best you can get doing one side is 8 degrees. But it doesn't make sense to do that because you'll have one side burning hot and throttling and the other would be fine. Either do the whole mod or don't imho.
@@CryptoAtHome I got almost 20 doing only the top side with Gelid ultimate 15W/mK, you might want to look into those pads for even better cooling. They are cheaper than the pads you used, at least in the US. It was hitting 110 but now holding at 92 degrees even at 100% power limit +1000 on the mem clock. Also have a couple tiny heatsinks on the back plate with a fan blowing on them, those didnt do anything for temps before I replaced the pads though.
20 degrees doing only the back sjde? Impressive. Usually people report between 2 to 8 maximum.
I can do a little feedback 9 month later, my 3090 FE still rocks with the thermal pad mod, nothing to say, thanks again !
OMFG! I just finished my mod. Same exact pads and placement as you and I am 24 degrees cooler at the same setting. I can up my memory now to over 1000 bump my power limit up to 80, same fan speed and I am getting 20 percent better hashrate. Oh and I can close my case side and still be 15 degrees cooler than before. I want to thank you so much for this video.
A couple things I want to recommend. Don't put your pads on the backplate side until you have put the board back onto the cooler and reattached the IO plate. It's too easy for the pads to fall off.
Hey , happy this helped you . Cool to see such great results :)
Merci cher compatriote pour ce magnifique tutoriel !
I've done exactly as said in this video now my hashrate goes 116/118mhs fully stable, no incorrect shares, with temps of 45°max for core, and 82 for memory !
•My settings are -150 core, +900 mem, power limit 305w, fan 60%
•I just prepared all my pads in advance thanks to the PDF in description, then when I started to open the GPU all I had to do was clean and put my already cut pads according to the description. My GPU is brand new so I managed to take back the original pads properly in case of RMA I can put them back inside.
•As seen on other comments and posts, taking off the SLI cover before reassembly will let you gain more pressure on the PCB in order to have the best contact with the thermal pads, especially if you have the Thermalright pads.
• I used the thermalright pads, I was afraid because I've seen later that the Gelid would be better. But if you follow the instructions it'll be OK. Press gently the pads with your fingertips.
• I repasted the chip with MX4 paste, spread all over the chip and in the end a little drop more on the center of the chip (just in case)
I just finished doing this to mine. My vram temp is only down from about 105 to 96, which is a little disappointing after seeing what others have gotten, but it’s a definite improvement. My tip is to print the layout thats in the description at 64% scaling and it comes out the right size to use as a template.
I really can't comment on the pdf layout as it's not mine but hopefully this help others.
I am seeing about the same results as you. Disappointed in the small drop in temperature but at least now I can get around a 115mh/s / 102 degrees (102 degrees / 99mh/s before mod).
Don't focus too much on the temps. Micron has changed the optimal temps of the GDDR6X to 105 degrees max so as long as you're not throttling then your mod is successful.
Liked and subscribed got a 3090fe was hitting 104c on memory just gaming followed your guide now hitting a max of 84c on memory absolutely blown away thanks for all the information and that led connection was a fiddly sausage but got there in the end thanks a million
Thank you so much!! Well made tutorial!! The best! My temps are similar at first hitting 110c after this following this video exactly I’m getting 88c running even higher OC and getting 111MH/s!
Awesome results, enjoy.
Thanks for your support :)
What are your equipments? Mobo, gpu, processor, ram.
if its a 3090 u should be getting just under 120 mhs, u might need to check ur overclocks
Thank you so much for this tuto ! Before the mod, my 3090 FE thermal throttled like always when doing stable diffusion works. Now, It never gets higher than 72 degree Celsius and I can even do batch rendering now ! Even if my room is higher than 30 degree !
Just wanna report back, I did this today! Before I would get 112 C when running OctaneBench, and would thermal throttle. I'm not even mining, but 3D render and gaming (with RT) would make it throttle. Seemed almost like a defect product. Now it stabilized at 86-88 C at 1700 RPM. Approx 25 C reduction.
Had some concerns about it, since I have never opened a GPU before. Let alone one that costed me $2000 and took me 4 months to receive. Already sold my previous card, so I wouldn't have any backup if I screwed up either. I've been tinkering with a lot of tech lately though, so I had some confidence it should be fine. Thankfully that was the case. Took my time, used same tool set and thermal pads as you did. Easy knowing exactly which screwdrivers to use, dimensions of thermal pads and where they go when I had the visual reference. Thanks for the tutorial!
Yeah I've said many times that its not just us miners who can benefit from this, but also gamers and anyone doing anything remotely heavy on this freaking card. Enjoy your 3090 FE as it should have been from the start 👌🏻
@@CryptoAtHome Definitely. It really is unbelievable how they cheaped out on something so small in such an expensive card. Barely saw any reviewers mention VRM temps. Baffling oversight from Nvidia for their premium product. Maybe it's not as reported issue because so few people has the card.
It's not a reported issue because until not long ago, there was no way to see the memory junction temperature. This was made available long after release. Also, this problem is really minimal during gameplay which is what most reviewer checked.
Just did this with my 3090 from best buy and it was definitely worth it. Memory went from 110c to 90c. Thanks for the video
Good. It's just sad that after all this time, Nvidia is still using the same shitty pads 🙄
Thanks for the tutorial. Playing Modern Warfare/Warzone, my VRAM temp was 102-104. After replacing the pads, my max VRAM temp has been 82.
hey peyton, question: before the mod did you by chance lose frames while gaming. For me it seems that my 3090 FE runs unnecessarily at max fan speed while playing a simple game like csgo. Then when I play something like Escape From Tarkov, my 3090 sounds like its going to take off. Not sure what it might be but its boiling down to a vram issue.
@@peytonbrandt3943 yeah its pretty odd, I've ran the 3090 FE with a 5950x the past year and the past few months i've been having an issue where if I sat idle on a game my PC would freeze and most of the time I would have to hard power off my PC. After reinstalling drivers, changing power usage to performance etc the issue was 98% remedied. But now when I play CSGO my gpu makes more noise than usual and I even lose frames/throttle when smokes, mollies, nades occur at once. Now with tarkov especially (just loading up) my GPU fans spins extremely fast to where I don't even feel safe playing on the card. I tried to devolt the card as well but reverted that due to instability. I've got an evga 850 platinum PSU with 32 gbs of ram. Not too sure what would randomly cause my card to throttle on any game I play it's starting to get irritating, but I may change thermal padding or get a 1000W PSU.
I'll be downloading HWinfo today so I can get an idea if whether my vram chip is reaching 100 C as well, because that may be the overarching issue.
@@ushad Yeah, definitely try out HWinfo first. If that shows VRAM at 110°, then that’s obviously the issue.
Don’t waste your money on a 1000w PSU, because 850w is totally fine.
@@peytonbrandt3943 ok so I did some testing and the idle freezing is still here. When running a less intensive game like csgo my 3090 FE runs louder than it should (normally it would be able to run 2-3 heavy title games at once while streaming obs. Now the card has shat itself completely. Now when running a less optimized game like escape from tarkov I would get 100 C right out the gate on the loading screen then in game HWinfo told me my max was 107 C. Do you think I should contact nvidia and begin an rma?
@@ushad you could try contacting Nvidia, but they might just tell you it’s normal to have VRAM temps between 100-110°
Thank you very much for this tutorial. Before I tried a heatsink and attached a fan, temps were 48core 102 on the memory junction. Now with new pads(same exact ones you used) temp is 51core and 86 memory junction. Running at -200 core/+1000mem 80% power. Could finally turn my fans down from 100% to 70%. Big thanks sir!
We need the whole world to mod their cards. That will help with global warming 🤣
Enjoy .
Just done your mod, I can confirm a solid -20deg on the memory :)
Yup, that seems the average drop. Enjoy !
Just finished doing this with a repaste and while still stock it’s allowing more power drawing and lower fan speed which helps immensely. Hopefully the links I used from your guide helps your channel out.
Thanks for your support !
Unless you're not mining, you shouldn't use default settings as they're really sub-optimal.
@@CryptoAtHome yea I’m doing mining tuning now. Still keeping it around 90 c on the vram but much higher hash rates.
Lowered my temps by ~18C. Good video tutorial.
just got one ordered through best buy, probably doing this soon. Thank you.
This is it chaps. My 3090 has gone from 105 mh at 110C memory junction -> 123 mh at 90C. Bravo.
i cant get 80mh without my fans sounding like a jet on an FE card i cant put the power higher than 60 without the mem temp at 110. is my card fucked up?
Did you change the thermal pads ? If not, then this is unfortunately the "normal" behaviour. Thanks Nvidia
@@CryptoAtHome well I ordered everything I needed so I'll just be waiting that for now. Even when playing games tho I don't get why it is this hot. What if people used it to render videos/3d modeling/ other vram heavy work applications? That takes up alot more time than gaming alone and the card runs this hot by default? Thank you for your guidance with this video. Gonna hope this guy survives a long life.
Games don't have the same workload. It's short (few hours max) and it hammers the gpu core mostly. And this one is well cooled. Video editing is in between but again, you're not editing video for 24/7. On the other hand, mining is all about memory and it will push to the extreme limit, 24/7. Remember, there is a difference between using a lot of ram like video editing and making use of the highest frequency possible like in mining. Now these cards were never sold as mining cards so for gaming and editing, there is nothing to complain about.
@@CryptoAtHome so for longevity I should use octopus miner instead of daggerhashimoto simply because of the vram temp difference.
This was the best tutorial I found on TH-cam. I placed the Thermal Pads exactly as you did and changed the GPU thermal grease as you mentioned in the description of this video. Before the temperature was 110 c° and now it is 89 running at 120 MH/S. Thank you so much!!
Well done. When I made this video I thought it was too long but I didn't want to cut any part as usually tutorials tend to skip on part they think is not important but some people might find helpful
Wow I guess you don't have a Founder Edition? I also replaced thermal pads but can't get below 105c° if I want a 120MH/S
Can confirm! The fix works. I did just as he did, added GPU paste and wrapped it up. Gaming wise, I'd be at 102C, now T Junction temp is 84C 👍
Hi mate. How did you apply the thermal paste? Some say X-pattern, some say out on and smear etc....
@@umirza I did the x with dot method but am noticing +20 hot spot temps when under GPU stress loads compared to the GPU temp. I'm going to redo the pads and paste with the spread method.
@@Inboc85 I ended up going spread method based up the recommendation in the thermal paste instructions and its been a night and day difference between stock.
@@umirza that's good to hear. Everything else was good, GPU temp, memory junction, but that darn hotspot temp field has me worried.
Just done mine and used spread technique very messy but gpu core temp the same as before and hot spot temp 81c memory down from 104c to 84c in bench tests 100% usage
Great tutorial! The PDF was super helpful for me. I mostly do machine learning on my 3090 and I saw about a 10c improvement in memory temps and I was able to bring the fan speed down 30% as well! Thanks very much!
Nice. I didn't make the pdf but its definitely helpful.
@@CryptoAtHome Your video was excellent too, I wouldn't have figured it out my myself. Also in regards to your comment at the end about swapping out the pads again for Fujipoly thermal pads, did you ever do that? I'm not sure if it's worth it. I think the VRAM chips are rated for like 100c to be in spec. So you may see lower temps by doing the swap but I'm not sure you will see a performance or a lifespan improvement by doing that and it would be extremely expensive. But I would still be interested to see what the thermal improvement is (if any).
Thanks. Nah, I didn't try. Fujipoly pads are way overpriced and I doubt the difference in (maybe) slightly lower temps makes up for it. Plus its a one-time use pads as they're really brittle. All-in-all, the best choice seems to be the Gelid Extreme so far.
Great tutorial! Really appreciated the precise measurements for each thermal pad. Dropped my memory temperatures by 20 C.
I'm an engineer. Software engineer, but still. We like to be precise, not just "cut the pads to fit the VRAM modules" :)
I was completely confident tearing my 3090 apart thanks to this video. Temps are down 17-20c. EZ. much appreciated.
Great video. With stock pads I can mine at 116 Mh/s with GPU memory temp at a constant 106 degrees. Massively better than what you were getting but still makes me nervous, especially when thinking long term. Waiting on the same pads from aliexpress to arrive before making the same thermal pad change. This video gives me much greater confidence in doing it. 👍
Hi, thanks. I doubt you will see such massive change in your case as you had pretty good results. Theoretically 106 degrees is ok-ish as GDDR6X is rated up to 120°C and Nvidia deems it safe up to 110 degrees. But yeah once the summer is here and the heats goes up, it will probably reach the dreaded 110°C.
@@CryptoAtHome Exactly my thoughts. PC in man cave/garage where I keep the heating off when mining, so largely same temp as outdoors. Gets very hot in there in the summer so will be a different story then I suspect.
Me too! I will get 112Mh/s with 106 degrees with stock pads!
@@doitdeluxx I was hitting 112mhs with stock pads but bouncing off of 110C.
I used slightly worse pads than these when I did this a month ago, only did the backplate, and now I hit 120mhs stable and don't go over 102c. If I take it back down to only get 110-112mhs I can keep temps under 100 after just the backplate and 11w/mk pads.
@@CryptoAtHome GDDRX data sheet on Micron shows operating temps between 0 to 95C (in.micron.com/products/ultra-bandwidth-solutions/gddr6x/part-catalog/mt61k256m32je-21). Long term 105C - 110C will have an impact on the VRAMs.
Followed this guide and was crazy impressed with your teachings, me and my brother did it with a 120x120 and still had some to spare. Thanks!
Thanks so much for this, just followed it using exactly the parts and tools you used (I looked for the 17W/mK from fujipoly and alphacool but they're much more expensive or out of stock, or both).
I was running at 60% power limit an -502 on both core and memory (using afterburner) to get about 71MH and 95*C. Now on the same settings it's giving me 76MH at 80*C. So only a 16*C drop for me but I was about 75*C off ambient (assuming 20*C room temp) not 90*C so I wouldn't expect to get as much. I also replaced the thermal paste with what I had left over from my Noctua NH-D15 so that may be transferring a bit more heat and reducing the improvement in memory temps a little.
Hopefully now my 3090 FE can pay itself off a bit quicker and last well, thanks! :D
Edit: Now up at 95*C again which is as hot as I want it getting, that's at 80% power limit, -200 core clock, and +1000 memory clock, giving 115MH. That's a 62% improvement at same temperature and I've got some fine tuning to do yet fiddling around with clock speeds and maybe power limit up for down very slightly, so may squeeze just a little more out of it without breaking 95*C. Awesome improvement!
Yeah fujipoly pads are way overpriced unfortunately. And that will add to the cost so your ROI will be longer :/
Pretty cool improvements imo, even with "only 16°C" drop. I'd say that's very good already ;)
Seriously do it. Even just the backplate vrm hotspots and vrams. Ive seen a big drop from 105deg c to 92deg c with an undervolt.
Thank you for the clear instruction without background music
Really impressive results and good video.
Thanks. Yeah I was surprised myself with the result but now I definitely recommend it
Thanks for the tutorial and PDF. Got my temps down 20C with 70% fan speed
Just did this now to my 3090fe! I repasted the core and used the thermal pads you recommended, and my temps went from 65c -> 61c on the core and 104c -> 82c on the memory!
I was really nervous at first but thanks to your guide, my card is now better than ever! 👍👍
Wow... just, wow. I'm gonna get this done this week. Best tutorial I've seen in a long time! Thank you!
Did both sides. Before: 61% power limit no overclock for 95c; After: 100% power +500mem for 82c. Thanks.
Great but why are you using 100% power ? Or you mean for gaming ?
@@CryptoAtHome I'm not just testing that the limiter can be relaxed without heat coming up
@@altitudelow I have mine +1100 on mem with 85% power
Just wanted to thank you for this guide. I used this video to do the same mod to my Founder's Edition 3090 today, and did indeed see 20-25 degree drops in vram temps. Instead of undervolting, I can now overclock and keep the vram at a max of 90 degrees. Truly stunning that Nvidia released these cards in this state.
I just completed this by following your direction I really liked that you put the dimensions for the thermal paste that you cut. That by itself was very helpful! The only thing I did was also change my GPU thermal paste to Artic MX-5. Also I saw drastic drops in my memory junction. With my case closed while mining I'd hit 102 to 104. If I open my case and have a blower style fan blowing at the 3090 with a heat sink and a noctua 120 mm fan blowing on the heat sink I'd get 94 to 98. But now I get 84..with my case closed I get 88. Very happy with the results and your help thank you!
Hey, nice to hear that this tutorial helped you and you also saw a drastic drop in temps. I also keep my case open. Enjoy!
Thanks for the tutorial. Totally recommended. It took me a few hours (I was doing it slowly step by step) and some planning with the cutting templates but everything worked flawlessly and temps down about 15-20º. I also cleaned and applied NT-H1 to the GPU. I don't understand why nvidia used this low quality pads...
After replace pads how much temp are you gpu die? Bcuz this will make you vram better but size of pads this guide is abit wrong
@@intech7863 Do you mean memory pads @ 1,5mm is not right? Didn't have any problem with them so far. GPU die temps was at least -5º I know because I took screenshots before and after in same scenario, time and configuration. But the test was minning eth not gaming.
@@jaimito061 1.5 is right just some vram pads size is wrong example V pads and pci-e pads on both side gpu and backplate must be cut perfect.And left strip pad on die side must be cut less wide then the this video .Since you not gaming no problem at all
@@intech7863 can you explain plz whats wrong with that pads in guide? What problems will i get in games with it?
@@ДенисВладимирович-с9ц from one forum i just paste here .
-Hi, after doing the pad mod, the junction temp is good at max 84 C, but my cpu temps are more than 10C higher than before while my score in port Royal is lower.
Is that normal?
I first thought of to little paste on the gpu (see picture) and repasted with lots of mx4 in a cross. Makes no difference.
ANSWER!!
What thermal pads did you use on the GPU Core side?
Those thermal pads are either too thick or too hard (not squishy enough).
Are those 1.5mm pads?
If those are thermalright pads, on the core side, try manually compressing them down about 0.3mm with a piece of glass on a flat, clean surface (do all of them together at once so the compression is identical. You will have to trim them again to size when you're done (especially the VRM pad at the top). If this ends up not working, try Gelid Extreme 1.5mm pads.
Two other problems.
1) the VRM pad at the top is much too wide. It's covering small SMD rectangular caps next to the VRM's that sit higher than the VRM's. Trim that down so that those small SMD caps are not covered up. You can trim it after doing the compression I mentioned
2) the single chip VRAM pad on the left side is too large. This pad, if it's larger than the VRAM chip itself, will interfere with the edge of the heatsink. There is literally no room for error here. After you do the compression of all the pads, make sure you manually cut that so it's the exact same size as the VRAM chip and no larger! Do the same trim for the backplate single chip VRAM pad also.
Or just swap out the pads for Gelid Extreme 1.5mm pads (and remember to trim the VRM strip pad perfectly and the single chip VRAM pads!)
--Hi, I used Thermalright 1,5mm pads.
Will try to make the pads fit the vram exactly, although the original pads are a lot bigger than the VRAM, as well.
Thank you.
--ANSWER!!
The original pads are -extremely- squishy, far more squishy than any pad you can buy normally. They are more like some sort of putty or phase change material than an actual pad. So the tolerance for compression is extremely lenient. It is also this problem that makes aftermarket pads so tricky, to maintain the correct contact pressure on the core.
From looking at people's tear-downs, it looks like the original pads compress by about 0.3mm (1.5mm to 1.2mm). But on the GPU core side, the thermalright pads only seem to maybe compress 0.1mm after mounting, and then there are not enough screws to make it compress more. And I think 1mm pads are too thin (no one has tested this on 3090 FE). The only screws that attach the PCB to the heatsink are the four GPU Leaf spring screws! Nothing more. This is a big problem. So you screw the leaf spring in down, to the end, but the pressure downwards is not enough. And there are no screws around the VRAM to help. The screws at the edge of the PCB (Backplate, Torx/philips) are useless for mounting pressure!
Compare any AMD reference video card (r9 290X, Vega, etc). There are screws all over the PCB! And they screw the PCB into the heatsink. like 8 screws, not including the X-bracket! Then for Vega 64, six more screws for the backplate, hah!
Just completed replacing the thermal pads on my RTX 3090 FE. What difference! I'm now mining @ 121 MH/s with a GPU temp of 58, fan @ 75% and VRAM temp of 94. Thank you for this amazing step-by-step guide.
Nice. Don't be afraid to push the fans, they don't wear out so easily if you keep them at a constant speed. Enjoy 👍🏻
@@CryptoAtHome i did this but my temps are still high. when you showed your results, was that factoring the additional heat sink and fan you added?
Yes but the heatsink does basically nothing. I removed it.
might be a good idea to remove and reapply gpu thermal paste. not sure if you mentioned that in the video.
Not in the video but in the description, in the pinned comment and in at least one hundred replies to comments :D
I almost want to reupload the damn thing to include a repaste haha.
Thanks for making this guide, after a rather stressful five and a half hours of really taking my time and working out every step one by one I was able to do the mod and have seen some of the best gains yet coming from the worst temperatures I had only seen reported by one other person.
I don't mine but I do mostly 3D render and occasionally game so I really needed to do this, the highest I saw before the mod was 112 degrees which is crazy and I think that must have been with the stock fan curve as when I did another lot of testing before the mod yesterday I only got as high as 106 with a custom fan curve I set. Well now I've seen it get as high as just 82-84 degrees under rendering load which is crazy, that's almost a 30 degree drop compared to the worst temperatures I saw so I'm very happy.
I did of course repaste it too and I used Arctic's new MX-5 with the spread method as it's nearly impossible to get TF8 or TFX in more than 2g tubes and there have been too many people reporting dried up tubes for me to justify potentially wasting £12 on a tube, a 20g tube of MX-5 is £22 which I bought to repaste a few things and turned out to be a good call as I had to clean off the paste from the die twice due to mistakes.
You know what though the MX-5 is actually really good, it's got a higher density to it than MX-4 which someone on reddit had used on theirs and reported that their temps had not changed which is almost the same case with me, I actually saw some minor gains on the core temp, only by about 1-2 degrees max of a difference when rendering but I think that the TF8 or TFX really aren't the absolute only ones you can use.
The only minor concern I see is that the backplate appears to be slightly bowed up in the middle and upon inspection of the stock pads under it when I first took it off they appear to be 1mm rather than 1.5mm but they weren't all making full contact with the chips. I think perhaps it's possible that the 1.5mm pads need to be rolled out a little to be around 1.25mm for the bowing to not happen. While I am very pleased with my gains I cannot help but be a bit concerned about the thickness of the pads on the memory chips causing other areas under the backplate to not be getting the full amount of contact they need so I might be losing some performance there.
Overall it was an excellent result and as long as you take your time and don't rush things it'll go well. Also I used simple masking tape to pull off the little screw caps, you don't need anything stickier than that really. I also used little strips of it to hold the wires back so I had an easy time of getting the PCB back in, you don't need to use any tape sticker than that or you could end up tearing a cable trying to get it off.
Five and a half hour, boy did you take your time. Must have been the five longest hours of your life :D
Well at the results are there, glad it all worked out.
And yeah MX5 or 4 is a perfectly good choice, no need to rush and buy TFX or TF8.
Enjoy !
@@CryptoAtHome What do you think about the issue with the bowing backplate? I think there could potentially be some performance loss if it's being pushed up in the middle by the memory chips pads.
I can't really say. I haven't noticed this bowing from my side but I can tell you that me and a lot of others have done this mod this way and its been flawless so far. All that with mining 24/7 so I don't think you have much to worry in your case. Also I wouldn't advise mix-n-match but if really you feel insecure about this, try it like this first and then you can always change the pads with 1.5 gelid pads which are softer and will squish unlike the thermalright pads.
I came from a forum where we are all fighting this problem together. Thank you very much for taking the trouble and clearly demonstrating all the stages of replacing thermal pads and giving advice. But why didn't you remove the old thermal paste and replace it with a new one? :)
Simple answer: I was still waiting for the paste to arrive and couldn't wait any longer :). In general GPU temps seem good anyway. But I haven't tried in gaming, which would push the core. Over just a few months, I went from my old 1070 to a 3070 FE to a Gigabyte Eagle 3080 to a 3090 FE. I've had the card only for a few weeks and as I said in another video, I'm a Tech Lead and don't find myself with enough time to play anything really.
@@CryptoAtHome Can you tell me which PSU you are using with your RTX 3090?
Don't believe all you read online :)
I have a Ryzen 5600X, 3090 FE, 64 GB, 2 SSD and I'm using my trusty Seasonic Focus GX with "only" 650W...
Awesome tutorial.
Made yesterday for my 3090 FE. I'm not a miner but I was facing FPS drops + 110 °C VRAMs
OCCT Stress Test GPU = Stable @ 68 °C with FANs @ firmware RPM (Maybe 30% or 40% RPM)
Tips for FAN connectors: Use a credit card to push the connector horizontally when connecting back.
VRAMs decrease of 20°C is real with 1.5 mm pads.
Used Arctic MX-6 for GPU.
---
My 3090 FE was brand new when I bought it last year, I discovered that the cold plate was scratched (Thank you Nvidia for the quality control). Original pads were sticky + kind of fiber inside.
Used Isopropanol 99,9% to wipe everything (and patience).
Interesting idea to use a credit card 👌🏻 . That cable is indeed a pain.
Thank you so much for the awesome tutorial. I followed your guide and did it myself, but unfortunately, I see hardly any improvement regarding VRAM temp. I am looking for a root cause and currently my interpretation is that the 1.5 mm Thermalright pads may be to slim for my card. Did you consider using 2 mm thermal pads? Why 1.5 mm?
No don't go for 2mm, you will have terrible contact. Some people are reporting better success with 1.5mm Gelid Extreme which are softer than thermalright pads.
@@CryptoAtHome I just replaced with GELID extreme and didn't get any drop at all.
Took me like 2 hours to do it and it worked!! My temps are 18 degrees lower and im gettin 20 more hash now! Thanks dude!

Thanks for the video. Just to share my experience I only replaced the thermal pads on the front pcb (the easy side without the gpu) and it improves temps, but you'll still see throttling when mining. I can get around 95-105MH/s now using -90 Core, +950 memory, 90% power limit, 80% fan 1 and 50% fan 2. I can get about 116MH/s when fans are on max and monitors are off. Fan 1 speed makes the most significant difference on hashrates. Your case cooling will also determine whether or not you can sustain this rate and your hashrates will vary.
I realize only doing one side wasn't the scope of this, but if anyone else considers only replacing one side you will still get throttling albeit with better speed so I'd consider it worthwhile.
Actually I know a lot of people will be afraid to do the gpu side so thanks for sharing your experience with only the backplate-side modded.
What are your junction temps like before and after?
@@MatthewTheCaveman Sorry don't really have the data cause the before was so abysmal I didn't bother. I'd assume that if full pad replacements are giving people -20C then replacing just the top side will be about -10C. It's obviously not that 1:1 but it's enough to improve hashrate performance over a long period of time and also stop it from throttling in games. Playing Hunt Showdown in 1440p at 162fps I max at 100C now at 114% power limit.
Don't you need to replace the thermal paste??
You don't "need" to but it's probably a good idea, yes. I might do it another time if I see the gpu core temps get too high to my liking.
@@CryptoAtHome Definitely looking forward to this. I heard the paste isn't actually the "usual" thermal paste as well.
Yes, I think we saw the same information. Someone said, and I quote, "That isn't dry paste, it's a phase-change TIM tape after it's melted/set into place. Most machine-assembled sinks that need a really high W/mK use it because it's a convenient form for automation and as efficient as paste."
Thank you for making this video. My RTX 3090 FE has been on the loud side since I got it but for some reason Days Gone was really making the fans take off even though my GPU was only at 64 degrees. I checked the memory temperature because of this and it was topping at 104 degrees. I followed your video to replace the pads and also reapplied thermal grease. Now during the same game, the memory is topping out at 90 degrees (A 14 degree drop) plus it is much quieter now.
Nice to see this also helps out in games 👍🏻
Thank you for all the help! Went from 107c 100% fans to 86c 60% Fans steady!
Thank you for making this video. I applied the pads and technique you did to my 3090 FE. I also applied Thermal Grizzly Kryonaut to the GPU Core. I'm seeing about a 14-16 deg C temperature drop. The best part is that the GPU fans don't have to run as high anymore. It was very noisy before and now...so silent!.
Yeah 3090 FE fans are super noisy at high rpm. Enjoy !
14-16 deg in gpu temp? Or vram temp? What’s your gpu temp
@@ThaAlumniMusicGroup VRAM temp. GPU temps seems to be about the same as before.
Thank you so much for this. I am getting almost no throttling while mining in between gaming after doing this. Fantastic video!
Thank you. Yes it's a big change but we wish we didn't have to do this mod to get this perfs.
Fantastic video, very well explained.
I use a single 120x120 pad for this as that was all that was available but it worked just as well.
Followed your link and had the video rewinded multiple times but everything went smooth with major temperature drop. I was hitting 108 in gaming max now max is 68 degrees. Mining is great too now I’m new to that but it’s obviously helped ALOT
Just spent the last 2 hours doing this to my 3090 FE. Thank you very much for putting this together. The measurements you provided for the pads were extremely helpful and saved me a bunch of time.
I hope your mod is successful 👌🏻
@@CryptoAtHome it was. Everything working well and junction temps doing great at 120 MH/s and 60 percent fan speed.
60% fan speed ? That's awesome. I keep it at 70%
@@CryptoAtHome will do. Thanks again.
@@radian2323 What are your settings, and are you using Precision or MSI Afterburner?
Bro instant results after doing this. 30 to 32 degrees temperature drop. Am getting 120 mhs at 78 degress. Thanks alot.
Your guide was spot on... 25C decrease on my VRM temps while gaming and mining easy to follow took me about an hour doing it carefully
I did a similar mod on my Gigabyte 3080 OC and that brough the temps down by 20C on the VRAM, well worth doing
Nice! I am getting the same results after replacing my thermal pads. I got my vram temps down to 82c at 100Mh/s on 3090 . I also put aluminum heat sinks attached with thermal pad on top of card with fan blowing over it. It definitely helped by 4 deg c.
Yeah some people didn't do the mod and just put several small heatsinks to help with cooling. As long as it helps...
Hi Ninja, would you be kind enough to put a picture to understand what you did ??? Thanks
Nerve wrecking solution that got me 9 degrees difference running Heaven benchmark. It's not breaking the 100C anymore so that's good. Great Video.
Thanks. Yeah the first time its a daunting task but it just needs time and patience.
Thanks for the video - extremely helpful, especially the dimensions… saw an immediate difference in temps! Anyone else notice that the old pads were really greasy? Serious pain in the rear to clean all that up…
Yeah and believe it or not, they're not even the worst. You should see the ones on the Gigabyte cards. Dear lord...
Followed the video and added the same thermal pads. Wow 22 degree drop. Thanks Nvidia. I was using an extra 360mm radiator with a thermal pad for an 8 degree drop prior. Now it looks cool again and runs cool. Thank you so much for this video
Heya, nice drop ! I'm glad this guide was useful to you.
where is the radiator ? thx u
I already had active cooling with heatsinks on the back and a NF-A12 pushing on them. Best result was 92C at 100% fans. I've just done both sides following your vid and I'm now at 82C with my fans at 75%. Also really enjoyed the teardown!
Can't thank you enough! 😁
Cool :). It's funny though, when I did this video, I thought it would be viewed by only a few people. I didn't expect 20k people wanting to mod their card.
@@CryptoAtHome ngl I was so game to rip it open, and those temps had me seriously worried! Props man, congrats on the views (and for fixing Nvidia's bad design)
FYI, down to 78C at 100% fans
Thanks. As for the fans, don't run them at 100%, it's not worth it and you're gonna kill them fast.
@@CryptoAtHome deffo not. Too loud for me aha. Thanks again
Awesome video. Just ordered the pads. Got the 3090 FE last thuesday and have been mining now for almost 24 hours. I didn't have to lower the memory speed and am currently getting 104C max @ 107 MH/s. Still too high for my liking, so I'll use this video as a reference for when the pads arrive. Thanks a lot! WIll add my temp difference to this comment when I've done it
Just want to give you a shout out! My card would hit 110C on memory temp right away at stock settings. I also replaced thermal paste. Now it is mining without a problem and the highest I have got on the temp is 96 C while pushing it to 121 MH/s. Good work my friend!
Thank you :)
Make sure you have sufficient air-flow to evacuate the extra heat now that you've modded the card.
Many thanks for this guide, i have successfully made the changes to the thermal pads and i am also getting -25 degrees.
Everyone should do this!
Couple of things to note; when pulling the PCB away make sure you prise it from one end as my GPU was really cemented to the cooling block and trying to pull the PCB away level wouldnt break the existing GPU thermal pad it just kept lifting the whole cooling system (first time poking round in a gpu so i was very scared of breaking it)
You will need to reapply thermal paste but make sure it doesn't conduct electric (some do)
Happy happy happy. GG
-25°C, not a bad results for some cheap pads, am I right ? GG :)
@@CryptoAtHome I can finally crank it up to safely get 120Mhs!! ty ty - Makes you wonder why Nvidia sell £1.4k cards with sub par thermal pads...
Profit of course 🤑
@@CryptoAtHome might of spoke soon, getting alot of instability now, currently trying to troubleshoot but even dropping my 3090 down to the settings I had it on before I modded the thermal pads is resulting in crashes. I had it mining at 90% power, +1000 MC, +100 cc, mem junc temp= 84-86 degrees C @ 122mh/s
along side a 3070 at 50% power +1200mc, -500cc @ 62mh/s for 2 hours then it crashed. It then started crashing more often even when I reduced the 3090 settings back to 60% power +600mc -100cc which I had previously had the card running at with the 3070 for days without a problem 🤔
At the moment I can't figure out if it is a coincidence. Any ideas?🙏
@@kylee3084 Hmm not many ideas no :/. I've been running the modded card 24/7 since I did the mod more than one month ago now and it's been rock stable. Maybe one of the pads slipped when you turned the card and this particular memory chip is overheating causing the crash? 🤔
Thank you for this guide. Lowered my GDDR6X below 200F and now I can run my fans at 30%. Quiet and cool!
I have no idea what 200 degrees Fahrenheit means for the rest of us mere mortals but I guess it's good 😅

@@CryptoAtHome It is real good. My computer no longer sounds like a vacuum cleaner. Thanks again!
I did my 3090 FE today and it's been a total success. Thank you! I only use my GPU for 3D Rendering and If I run the redshift vulture benchmark about 3 times in a row I would blow past 100 degrees easy and I would just stop running it, I'm sure I would have eventually gotten to 110 degrees. I don't know
After the pad install I get mostly 86 degrees. Wonderful!
Just a couple of tips I discovered that might help.
A. Take off the cover to the sli bridge cover thing on the PCB. It makes it easier to remove and reinstall the backplate.
B, True the old pads are sticky but a plastic pry tool removes them quite easily.
C. As another poster on here said, use scotch tape to hold the wires back during reassembly. So easy.
I used thermal grizzly kryonaut and I seem to be getting better temps on the GPU as well.. it was really a problem before but the less things heating up the better.
The LED light cable really is a nuisance. I wish I had a tip that would help with that but it really is a pain in the ass. The good news is that actually goes back in quite easy during reassembly.
Thanks again for saving our cards CryptoAtHome. :) Super excited to start rendering again.
Nice ! Yes the led cable is a pain but that's why I shared an "easy" way on my other video.
"The less things heating up the better". Well that's technically not correct. The heat produced by the gpu core, vram and vrm is the same. You're just improving heat conductivity/dissipation ;)
@@CryptoAtHome Haha.. I probably would have better said, the less things catching on fire the better. ;) I saw your other vid on the led, mine was still so snug in there that when it finally lifted out I swore it broke... All good though. Thanks again man! Hope your channel does well, look forward to more content.

Shared results with a few discords I'm in and hopefully you'll get more views/subs. Pre mod: my best numbers were 110mh/s 96c mem 100% fan. Post mod: 123mh/s 80c mem 70% fan.

Thanks mate, I appreciate it 👍🏻 .
Glad it worked out exactly as "advertised" :)
@@CryptoAtHome BTW, I attempted to buy the pads from your affiliate link but it took me to Amazon.fr and I am in US. I had to just search and buy them myself... If you can get/provide US affiliate links as well I'm sure you'll get more referrals.
Also the LED cable was tough to get out even with the second vid. I had to lift it up and slightly to the left. Came out easy once I found the correct angle, if that helps anyone else.
I don't remember having to lift left but maybe this depends. Hopefully this helps some other people, thanks for the tips.
And thanks for the affiliate link idea but I actually make no money from this :)
I tried 3 times already to get in but once I reach the required limit, Amazon just closes my account and drops all earnings. Apparently I'm "too small"... But I'll keep trying. Maybe if I try Amazon US I'll get in 🤔
Thank you, I was getting a peak junction temp of 106c while playing Control with the fans maxed out at 2400rpm even though I had undervolted the card. It was the first time I had taken a card apart and I was a little nervous but I followed your video and hey presto! I have removed the undervolt and am now getting a peak temp of 94c and the peak fan speed of 1365rpm. My card is so much quieter now and I even feel I have the ability to push it a little.
Yes the 3090 FE can sound like a jet engine at high fan speed so lowering temps definitely helps.

@@intech7863 i heard the thermal pads were improved in the early part of the year, so I guess it depends when you got your 3090FE. I originally noticed the problem in warzone, but an undervolt sorted that out. However in control with everything turned up including ray tracing the peak junction temp were bad and the card was so loud. No issues now I replaced and 94c peak junction is fine, they cool a little once the fans ramp up a bit. It was always about the noise anyway and now the card is quiet, except for the coil whine.

Fantastic, great video, thanks. Mine was maxed at about 105MH/s (with the memory jn temp at 110)... I throttled it back (so I didn't cook my card) and was getting 100MH/s at 102 degC. After the mod, I'm running 122MH/s at 96 degC with the fans at 50% (20% lower than before). Afterburner set at Core -500MHz, Memory +1400MHz, Power Limit 90%. Quieter, faster, cooler. PC (monitor off) running at about 375W. Damn good, awesome. Poor that NVidia didn't do it!
Let's make a petition to change that 🥳
Just followed your guide. -20C off memory junction temps. Awesome!
One more warrior joins our rank. We are legion :D
Great video very informative and the dimensions to cut the pads saves a lot of time. I followed this in about 2.5 hrs and was able to assemble everything back together. I ended up also re applying the thermal paste with TF4. This easily knocked 15-18 C off my running temperature. I do not feel like my card is going to burst into flames. I would also recommend four pad packages as you can be a little less tactical with your cuts.
Good job and good video!
Thanks, yes I saw people sharing the pictures of their thermal pad applied but nobody gives the dimensions so you're left on your own. I thought it would be helpful :)
Thermalright Odyssey is pretty cheap so you can go with four pads and it won't ruin you.
Enjoy!
@@CryptoAtHome Just an FYI you're missing one of the width measurement for the front of the PCB. It wasn't hard to infer what it should be.
Also falkentyne posted that removing the NvLink cover before putting the backplate back on allows for more pressure to be applied to the memory modules. I removed mine and so didn't do any before or after measurements but it doesn't hurt to remove it and then reinstall once the backplate is back on.
Yeah I know about the width but I didn't know where to put it and assumed people would be able to infer as you did :)
I saw his comment on Reddit but I'm not sure I want to remove it and risk losing it. I have a damn cat that snatches everything.
Fantastic video! My 3090 FE was struggling. I tried to keep it at 100C or below, but had to run low clocks and high fan speed just to get a hashrate around 100mh/s.
Now, with these thermal pad mods, it is like a completely different card. I am running at a 90 PL, 1300 Mem Clock, -502 Core Clock, and a nice low 70% fan - and temps are sitting at a comfortable 88C and the hashrate sits around 123 mh/s. That said, I have tested higher OC settings keeping temps under 96C and managed over 126 mh/s and am confident I could go higher - I just don't want to throw to much wattage through the card.
I wouldn't push it so hard. 3 extra Mhs is nothing and it introduces instability.
@@CryptoAtHome Thanks for the tip. I have no plans to run it beyond my current settings (at 123 mh/s). I was just pointing out that it could handle the higher setting without overheating during a short test. The new thermal pads work great!
WOW, Till now, the longest and most detailed Video about Thermal pads on this card, thank you for that !!!!! i will try to do exactly the same by my 3090fe. Pray to god i will made it and it will work. Greetings

Yeah the 3090 FE is a card you buy first for gaming, not mining. I also mine only on 3070 and 3060 TIs as they don't get so hot.
Nice patient approach, good advice along the process.
I did this today. Before I was at 40 hash rate and 94 VRM. Anything over was 110 degrees on VRM. Now I'm at 88 VRM at 100% power and 111 hash. Not to mentions gaming performance is so much better. THANK YOU!
Heya. VRAM, not VRM, that's a different thing. Nice, you've got much better result but you shouldn't be at 100% power limit. You should lower it to around 90 and decrease the core overclock to -500.
Consider subscribing to help me out :)
Many many thanks !
All information needed is in your video, incredible job.
I replaced the pads today and my temps dropped as well by 20deg. But my gpu temp raised by 5. It's still better to have a gpu at 50deg than vram at over 100. Thanks for the video
It's actually normal to have the gpu temp increase a bit. It means you did a good (enough) job :)
Enjoy.
Thank you for the tutorial, definitely worth it. I'm getting better thermals on my VRAM.
Hi mate. I've done the mod on Sunday and tested the card until today. Everything works spot on, while before I couldn't even go to 95mhs without the card go to 100°, now I'm mining at 115mhs and the I get 81.5 median value over the last 3 days. Also this period is the hottest time it's been here in UK so I suspect on colder days the temps will be even better. My settings now are -200 core, +750 mems, 80% power limit, 70% fan speed. I couldn't see any increase to gpu temps, I used TF8 Thermaright paste and done the X and 4 dots. The cables were tricky but managed just fine with some clippers (for the led one).
I used the pdf with the pads layout and there's one small issue there, the pads that had a diagonal (the 2 that are not rectangular shape) should be mirrored. The way they are now will end up with the sticky part on top so if you place the pads on the card itself it won't be ideal.
Thanks a lot for the tutorial and goodluck to everyone who attempts this mod.
Yeah it's getting hot everywhere ( we're at 29°C here in Paris today) so our precious cards are gonna suffer. Good timing for doing the mod.
As for the pdf layout, thanks for pointing that out. Unfortunately it's not mine. I provided the dimensions in the video and somebody made the pdf template afterwards, which I linked and credited.
@@CryptoAtHome Maybe I cut the pads on the wrong side. I cut them with the transparent face up so the pads should be ok if we cut with the blue part up. Anyway great job with the tutorial. One more thing that could help someone. When I assembled back one of the pads that is close to the bottom part of the card was actually obstructing the backplat to fully close so I had to open and trimm it a bit. If someone closes the backplate without checking for that could end up with temps that don't drop as much.
