Thermals change over on rtx 3090. I was getting lower hashes than normal. Opened it up and found an oily substance over everything. thermal pads not doing their job properly.
I apologise for the lack of any editing, commentary or professionalism in my work!!! :)
Prior to this, 96-105 mh/s
After replacing pads 121mh/s all day and all night
max temps around 88-94C in a closed room

Great video thank you!
I did not have to replace my thermal pads even in May 2024 but the core needed a repaste.
On my side I could tell so because the hotspot would creep up and would drop down very slowly.
As I have a 4090 TUF I was brave enough to open the card and give it a repaste, it now seems like new. :)
Thanks a lot for this very detailed video.
hey there i have also msi rtx 3090 suprim x...what is the size of termal pads of vram?size-thickness...
its really weird to see someone hit a gpu with a squirt bottle. even if its totally fine
Dude thank you for the schematic. I had tried two times to fix the issue to no avail. After reviewing your schematic, went from 110C under mining load (don't worry didn't mine at those temps) to 80C under load!!! Incredible! Gaming load is a FROSTY 68C on memory!!! Core never even touches 70C under a 448W load. This card is a BEAST if you get the pads and thermal paste right!
hello thanks for the video. Please what means these indications : BS75K*77.9.3*T1.5 in the pad sizes and location ? t1.5 means the height of the thermal paste ? in that case what means the BS88*58L*15W*2H ? which thermal paste you used for the gpu ? and finally whick liquid you use to clean the electronic board please ? Thanks
Brilliant video. Including the link to the diagram was very handy. Only thing I think should be mentioned is before you start make sure you have enough of the various thicknesses of thermal pads. I found myself needing 2 packets of the 1.5mm and ran rather low on the 2mm (pretty sure they were the ones. One packet of each of the others was fine. It could also have been me being a little generous with the pads too lol. There was a problem finding one or two thicknesses but I just went up to the next size, .25mm too thick won't be an issue. I've just reassembled the card, and it's SO much cooler! Thank you so much
You should try phase-change material Honeywell PTM7950. It comes in as a sheet, lasts longer, performs works better than traditional pastes and there is no pump-out effect. Instead of thermal pads, I advise you to apply thermal putty Upsiren UX Pro.
It is also a good idea to do undervolting.
Hey, thank you very much from France for your vidéo. I printed the pic of the card, but can you tell me exactly wich number I have to change on picture 1 and 2?
Thanks for the video, same here i start to collect pads, 110 - 108 VRAM temps and low hash rates around 98/111 MH/S. I am hoping to change them a couple days.
Some of the pads are 3.5mm and other are like 1.75mm what did you use on those?
i know it is little bit late but did u found a solution?
@@a4man90 I posted the measurements on reddit
hello, bro. can you say, whats a thinkness on all elements on card?
Thanks so much for this walkthrough video on how to change the pads! You encouraged me to replace the pads on my 3090 Suprim X since the warranty expires in a few weeks and I would like to extend the life of my card by changing the pads to prevent the VRAM going bad from the heat. According to the pad replacement diagram, the pads on the VRAM chips are 2.5mm thick. Unfortunately, where I live I can't find pads with this thickness. We have the Gelid GP Ultimate pads here and the closest thickness I can get is 2mm and 3mm. Do you think I can use the 3mm ones instead? Maybe I can squish them a bit before installing onto the VRAM? Or maybe I should stack 2 thicknesses, for example 1.5mm + 1mm?
Honestly 1.5 and 2 could work experiment with it. Yeah f temps are too high then remove
@@ripspeed6685 Ok, got it. Wish me luck! 😄
@@bgtubberdid it end up working stacking them on top of each other? I am about to do this same thing and would like to know before purchasing the thermal pads
@@MizzTizzy92 I still haven't got the time to do this. Once I do, I will report back here.
@@bgtubber Update?
Materiał pomocny, dziękuję.
Hello. The thicknesses of the pads are quite unusual.
How to choose correctly? instead of 1.75 I will give 2mm but what to do with 3.5mm?
Can someone give what pads to use from popular thicknesses?
1.5, 2.0, 3.0mm where to give?
At the beginning, I will replace it for the backplate and if it is enough, I will probably leave it there. It makes sense?
You can use 2 thermal pad sizes for all thermalpads 2mm and 2.5mm.
You use 2x2mm to make 3.5, you use 2mm to make all others sizes.
Just heat them compressed to 80deg C. Make the size you need. Nonsense to buy 5 different sizes??? Manufacturer is an IDIOT.
@ripspeed66 i cant find 3.5mm on Amazon. What do oyu use
i know it is little bit late but did u found a solution?
Good video, same as on the 3080 surpim x I have ... oil was dripping from the stock thermal pads. Should have replaced them instantly when the card was new, would have saved me the time to clean the pcb. Those on the backplate were dripping/sweating the most.
'Oil bleed' is common and expected according to the manufacturers of the thermal pads
Very helpful thank you !
I hate changing pads and paste so much... I just dont get why the GPU manufacturers cant just use reliable pads and paste from the beginning.
My 3090 suprim X is probably the worst of the worst when it comes to heat (103° vram on idle...)
Thanks for the upload!
Try the gigabyte models. They are by far the worst. Max hash 89 due to throttling.
Hi, if I want to change only the thermal paste, do I need to take out the backplate? Or the 4 screws in the back are enough?
I think the backplate needs to come off first from memory
Hey man I'm a bit dumb. Sorry for the retarded stupid question but in the schematic what does BS88 and BS75K mean?
Also L - is lenght, W - is width and H - Height? If so what is the thickness?
And are all the numbers there in mm?
BS88 and BS75k are the spec of the pads
Yes - the measurements are in mm
Hi ! hope i can get a response for you assuming the vid is a bit old . I did the exact same process with the exact pads. But my HOTSPOT temp went trough the roof . I cant even play on the card . 100 hot spot in anything . Please , on the heatsink part of the card ( front memory ) you used Odyssey 2MM , right ?
Hi. yeah 2mm thick pads. The only time I have heard of this happening is when peeps use a pad that is too thick. this causes the back plate not to have enough contact to dissipate the heat effectively. Did you re apply thermal paste to the chip itself? Hot spot temps are more usually indicative of the vram temp than gpu chip tbh. I would start by taking the card apart again and looking for an obvious issue. Maybe double check all pads are where they should be according to the imgur image I referenced in my comments.
Hope this helps...
@@ripspeed6685 hi ! Thanks the reply . I used 2mm Thermalright Oddyssey pads . They were very thicky , i compressed them and everything is fresh now . GL
Thanks for the video! I am about to start working on replacing the thermal pads on various Geforce RTX 3090 of different brands: MSI, Asus, Palit, Gigabyte...
I would like to make sure that the thickness of the pads will be right for those cards, considering that they come from different brands. I read online that (1,5mm) is good enough for both sides of the card. What do you recommend?
Thank you!
See if you can get a schematic for each brand. See the MSI one in my description
Hi. On a 3090 gaming x trio with the same thermal pad thickness?
Not sure. I wouldn’t have thought so.
how many pack we need for MSI Suprim RTX3090 85x45x2.5mm and 85x45x2mm
Just a peace of each 2mm and 2.5mm
Thas that card worked after your replacement?
anyone know the pads needed for the ti version?
Can you send me scheme for this and dimension of the thickness of the thermal pads
Thanks and btw great video man
Hi. Link added in main description. I used the diagram to determine what size pads go where. The only thing I would do differently next time, is to also change pads no3 1.5mm thick (located on backplate) as these were also nackered and damaged by the oily substance. On reflection I think the oily substance formed bc I sprayed an air compressor duster inside the backplate (at some point in the past)
@@ripspeed6685 I think it’s normal to have silicon leak out of the stock pads. FE does the same.
Also, check your desk mat for New Zealand ;)
@@RandomRemix holy shit!!! NZ isn’t on the map!!! Can’t believe I hadn’t noticed before 😂
@@ripspeed6685 Hey man I'm a bit dumb. Sorry for the retarded stupid question but in the schematic what does BS88 and BS75K mean?
Also L - is lenght, W - is width and H - Height? If so what is the thickness?
And are all the numbers there in mm?
which pads did you actually use from the picture of size and locations since you only did VRAM as I saw in comments?
Yes just the vram
Question, did you follow the thermal pad size according to the picture given? How are we gonna find 1.25mm thick thermal pads haha
i know it is little bit late but did u found a solution?
What have you used for the 1,75 mm pads? Can be replaced with 2 mm or better with 1,5 mm?
Don’t go too thin as you won’t have the necessary contact with the backplate to disperse the heat. Go 2 rather than 1.5mm
2.5 mm backplate ?
2.0 mm vrams ?
hi i was wondering if i got a new card and my vram is 100+ degres sould i just change the backplate? and sould i use 2mm?
Depends on the vendor of the gpu you have. At a guess, and speaking from experience, I am assuming you have a gigabyte 3090 as these are notorious for running hot 100+. I would definitely change the backplate vram pads before the chip side. In regards of 2mm, honestly I don’t know but 2mm sounds too thin to me. See if you can get hold of a diagram that shows the sizes of the pads.
Hello have looked at the picture once and not quite understood where now which thickness must go on the top picture I assume that 2H means the thickness or? and on the bottom what should T1.5 mean?
Top pic is slightly decieving as it changes from H to T.
Top is displayed BS88 which is the spec of the thermal pad, then LxWxH where H is the thickness of the pad to be used. The bottom just labels the thickness of the pad as T
Should make sense?
@@ripspeed6685 so i would need pads from 1.25 to 3.5?
@@Nomind271 it’s usually just the vram pads. But if your doing a full change then sure
nice ! thx
Welcome!
How the core temps are holding after 6 months now as I read some complaints about performance degradation using this paste after few months due to pump out effect. similar goes for wet pastes like Thermal Grizzly and NT-H1.
Okay as far as I can tell. I moved the rigs indoors over the winter to keep house warm. So far so good - I haven’t switched my heating on at all!! The 3090 Max’s out around 90deg
@@ripspeed6685 Is it 90 deg on GPU Core Temp, GPU Hot Spot Temp or do you mean Memory? as I have a bit of trouble with HotSpot temps on the same exact card. it could reach 95 C. I re-arranged my rig configuration yesterday so that CPU radiator is up top not front so GPU temps could be lower. I still have to test thought.
@@Ahmed.Anwar1 relax! these cards dont throttle until the mem/hot spot temp reaches 100-102. 3090 just run hot....really fucking hot. If you were asking me about a 2060 hitting 90 then Id be very worried but for a 3090 its just another day. In the summer I regularly reach 98 with no ill effects. Right now the rig is inside the house in a utility room. Its hitting 96 as a max and 90 as a low but keeping the whole house warm. Havent switched my heating on at all!!! The rig heats the house!!!
Are thermals improved after thermal pad replacement?
Yes much better. Highest peak is 98 Celsius in the high summer. These cards are designed to run hot. Do t freak if your seeing temps over 50/60 cel. 3000 series run hotter thats all. They can take it fine
6 different thicknesses?!?! o.O
guys, I keep saying, only the vram pads need changing. forget the rest of them as there is no thermal gain
What was the VRAM temp before the pad change? I have a TUF 3090 and a FTW3 3090 and both are at 90C with the stock pads at 28C ambient.
are you gaming or mining?
When I used to game on this playing Warzone it would hit nothing more than 55c chip temp with a custom fan curve set. Vram was around 80 c.
If you are talking about mining. I would say 90c is safe temp for vram. anything over 96 and it will self thermal throttle.
This 3090 that you see in the video was hitting 105-110c in a closed garage whilst mining and hashes were dropping to mid 80mh/s
Now I have changed the pads I get 88c with the door open, 90-92c in the night and 94-96c during the day with door closed.
I've set the Nicehash overclock to decrease the gpu power based on the temp pf vram. Most it ever drops to is 114mh/s.
Usually I would expect to see 121mh/s on a 3090 if all was well
@@ripspeed6685 I mean while mining at 120.5 mh/s. I also have a TUF 3080 and an MSI GXT 3080 and they were both hitting 108-110C while mining at 100mh/s; after I changed the pads on them VRAM temp dropped to 80C.
Hi.. what was the hot spot temperature before and after repading?? I have seen many videos with hot spot temperature increasing after repading.
Also will the thermal pad dimensions be same for msi suprimx 3080ti..?
Will only increase if you have used the wrong thickness pads. Was about 101 before - see comments. Now it’s 88
Hi thanks for the video. I am going to use it to do the same thing to my msi 3090 suprimx. But can you please tell me exactly what I need to buy and how many of each? So the 2mm pads are for one side but you say 1.5 for the back side? How many packs of each thickness please? Sorry I just want to make sure before I pay as this stuff is pretty expensive. Also I've heard people getting -20c difference from gelid which is a lot cheaper. Thoughts on that? Cheers
Have a look at the links in the description. You need the pad schematic
@@ripspeed6685 I did thanks man but I don't understand how you managed to create thicknesses of 1.75 and 1.25..
So what do I need to buy like 1 pack of 1mm, 1 pack 2mm, and 1 pack of 0.5mm? Cheers
@@trueyskye I only replaced the vram pads; nothing else
@@ripspeed6685 ok mate I've ordered 2 packs of gelid extreme 2mm because apparently it squishes down nicely to fit all spaces 2mm or under. Where as the thermalright stuff is just solid and you have to be precise. Will also order a 0.5 and a 1mm for finer tuning but ill see what temps I get with the 2mm first. Read that people have had -20c success with just the 2mm gelid extreme 🤷♂️
Will report back and let you know how it goes 👍
Big problem with just squishing oversized pads down. I didn't think the gelid extreme pads were electro conductive but they really actually are despite what their website says. Squishing caused the pads to mushroom over onto the tiny caps and short them out which stopped the card from working booting. I cleaned it all off and card came back to life. Phew! If you do it follow the blueprints to the letter. Buy one each of 1mm 2mm and 0.5mm and that should be enough to do both sides. Make sure you measure and cut the pads perfectly to avoid mushrooming over the sides of the chips. After I did it properly it works perfect. I lost about 18c so now I can mine without worry I'm frying my card! Getting around 78-80c now. Gelid extreme works great and is cheaper than the thermalrite but its definitely got some electro conductivity so be careful with it. Good luck!
I changed the thermal pads of my suprim 3090 for an ultimate thermal pads 15w... Results: before 100 Celsius mining at 68% power 115 MHS. After? 98 Celsius.... The same shit of the stock thermal pads... Wtf? I put all mm perfect... I can't believe it.... What happen?
Are there pads between the pcb board and the backplate which also need replacing ?
@@ripspeed6685 I have replaced all the pads (on both sides) following your 2 images and sizes. What am I doing wrong? I have put together in several pads 1mm + 0.5mm, or also 2mm + 0.5, but I don't think this is the problem, right?
The pads of the vram may not be contact with the heatsink correctly ... I'll try to remove 0.5mm from the other pads so that the pads of the vram make better contact. What do you think of this idea? but then it will be that each 3090 suprim X has different measures
@@Jordi_SP your vram pads need to be making solid contact with the back plate to enable the back plate to do its job of spreading and dispersing the heat effectively. removing .5mm may make the problems significantly worse in the case of them not touching the back plate at all.
@@ripspeed6685 what I'm saying is just what you mention, that the pads of the vram may not be touching the heatsink. Therefore, I say reduce by 0.5mm "the rest of the pads" not the pads of the vram. Let's see if this makes the pads of the vram much more contact, I hope.
Did you use more than one layer of thermal pads in order to match the original thickness (like using 3.0 AND 0.5 mm for 3.5 mm)? You can't really use two layers of thermal pads, or thermal pads on top of thermal compound. Better use a soft 4.0 mm and make sure to smooth it a bit before peeling its cover.
Hi thanks for this. Ive just bought a Suprim X 3090 and the hotspot temp was hitting 104deg, so ive repadded the backplate vram and now its much better, but the hotspot still reads 95 with an undervolt. Im thinking i need to repaste the whole card vram front as well then repaste as the hotspot must be on the frontside. The temps for vram are good though around 70deg at load, but hotspot still high at 95 with undervolt. Whats your thoughts? Thanks
Temps don’t seem too bad to me. 95 is a little high but only by 2 or 3 degrees. Re paste and re pad the front of you want to reduce further but honestly 90-92 is the best you can hope for with this card.
