When replacing thermopads, the most important thing is to measure their thickness. It is best to replace them with a thermal paste in gel form, such as Upsiren UX Pro Ultra, Laird 607 or K5 Pro.
Yesterday I changed the thermal paste and pads exactly like in the video. After sending my laptop in service for a problem, they botched up the repasting with some bad application and maybe bad type of paste, actually discovered they applied 2 types of thermal pads, of different thickness. I was getting very bad temps and was thermal throttling all day long. Was pretty angry of the discovery nonetheless. Anyway, now after i changed them all with the exact same products as in the video, Honeywell and Gelid, the difference was night and day. I got temperatures with 10-15 degrees lower(celsius). No longer thermal throttleing and the performance was like day one. About 9504 score in R23. Limited the turbo frequency down to 3.8 and have set it to Efficient Agressive and got temps even lower while boosting to 3.8 (scoring like 9406, with 5-8 degrees lower than default boosting settings)
@@klubsybeartutorials8453 use the same one as shown in the video, i think 1mm is the one but i dont remember as well. And buy the 90x50 one if you find it. I only had 2 options to buy : 120x20 and 90x50. I only bought 1 patch of 90x50 and actually was more than enough.
same happened to me. Took my Lenovo 5P to a local repair, they made it worse. I'll have to redo it myself. I don't think repair centers would have the same patience and meticulousness as when you di it yourself.
so you are measuring the thermal pads with an device like it is an operation, but you did not open the FAN casing to clean them thorough from the inside ? What only takes 4 screws each. If you are in there I would recommend also taking the blades out, they pop out very easy, also you can clean the heat pipes best from both sides if you take them out.
It was surprising to see a increase in temps of the gpu. Honeywell is just the best non conductive tim especially for laptops. I hope gpu temps gets lower with some uses as Honeywell being a phase change material it is very much possible.
Did you check the gpu clocks before and after the process? It could be boosting itself higher now than before, so higher temperatures but also higher performance. Another possibility to consider is that since the heatsink connects both chips, heat can be transferred from cpu to gpu and vice versa. Consider this scenario: bad heat transfer on cpu due to bad/dry paste, but good transfer on gpu. In this case, heat wouldnt be effectively removed from cpu to heatsink, leaving most of the heatsink dissipation capacity to the gpu. "Untrapping" the heat by reapplying paste could increase overall heat being transferred to the heatsink, thus improving cpu temperatures and gpu gets hotter due to actually sharing the heatsink now.
@@Eduardo1007 then how do you actually solve this issue. In my case after removing the heatsink my cpu temps have decreased but gpu temps increased. How do you solve it?
My first step in any hardware nowadays is undervolting. You get great results without having to tamper with the hardware itself. For gpus I recommend doing it manually through msi afterburner's curve editor (control F on main screen).
Concerning the hardware part, I see that the thermal pads were measured in the video, also accounting for the different colored pads (that could be different thicknesses). Using a pad slightly thicker than needed can lower the contact pressure on the actual gpu die, making it be hotter or not having contact at all and skyrocketing temps as if there was no heatsink at all. Getting the thickness right is very known on most thermal pad content. Something else I saw commented on thermal pad replacement videos and that isn't as common knowledge is that the pads can have different densities, so some are more tolerant to being squished than others. You can see this happening when some pads get very marked by the components they were on, while others don't deform /conform too much. So if you had a very soft pad originally and replace it with harder ones, this could be a problem. As an example using the data from the video, suppose you measure the original VRAM pads in their side like done here, and read 1mm. But the middle part was compressed by 0.2, so the actual height between heatsink and component is 0.8. If you use a 1mm pad that doesn't compress much, it may go to 0.9 and not more. So all around the gpu core you have these pads that didn't go as low, creating a 0.1mm high gap between gpu core and heatsink copper. It isnt much, thermal paste will fill it, but the ideal situation for thermal conductivity would be perfect contact between surfaces, with paste serving to fill microgaps in the materials. Having the slightest height difference can decrease heat transfer, making the gpu hotter.
Excellent video! Thanks for the comprehensive procedure and dimensions of every TIM used. One thing though - did you dust out the fins of the cooler? I usually blow compressed air from the backside if the fans are difficult to detach from the cooler fin stacks.
Yes, I used the toothbrush on the fin blades on screen and then used compressed air off screen to blow out what little was left. I made sure I could see completely through it.
Im not sure. I actually went back in to check if anything was wrong. I relapsed again and the temps were slightly better. I did read something about the heatsink not having enough pressure after a repaste and you may have to make a custom clamp. The heat sink has 3 screws instead of 4 on the GPU. I'm not about to attempt the modification as my results are better than what I had. I will check again since it has had time to settle.
It may that the gpu now has more "heatroom" and can clock/boost higher, so you can see in benchmark if you get more fps as before. This was the case for my Steam Deck.
From what I read around, this is the case for most laptops with PTM. It works great on the CPU's but not so much on the GPU's. So what I'm gonna do is use a good paste on the GPU and use PTM on the CPU. My GPU doesn't get that hot anyways.
@@Meanpooh I believe it needs to get above 90c a few times to get the true thermal conductivity. That's easy on any CPU, but I believe all laptop GPUs have thermal limits that never allow them to get that hot. It's almost like a curing stage. The more times it gets that hot the more effective it becomes.
I tried to open up the fans and I found out that there is no way how to open them and clean up compressed dust, only from the side vents. Rear vents no chance. So maybe this is bigger problem than the old thermal paste and pads and maybe people end-up buying new thermal system because of this.
i think the temp difference where no that much of a difference because newer lenovo laptops use a custom version of the 7950 called the 7958 which are made for lenovo laptops but i dont know if its on your laptop or not so you should research
LONG TIME no see though Meanpooh, I hope you and your family have. Been doing well and doing great, at the momment I. Appreciate your videos, and your long time support too. 💚😁🙌
Hi Retrolodge, Everything is great. I 've been very busy with employment as I'm currently in the process of changing jobs. I'm in the early stages as the job is broken up in phases. Really excited for this move. I hope you are doing well and appreciate the support!👍
hey a quick question, after you remove the heatsink from the laptop, do i also need to replace the thermal pads on the VRAMs or is it okay if only replace the pads on the die?
Thank you for this video! I have to reapply thermal paste on a legion 5 (2021), more than 24m old or more, and I wanted a reliable thermal paste solution + tutorial for it and this video suffices. Could you please tell me what happens if I use more thicker thermal pads? I will go with PTM7950 for sure but im curious about thicker thermal pads
Hi, I recently opened my pc to change my thermal paste, but unfortunately the thermal pads were all dry, I would like to know if I should take Gelid 1.5 for the vram and 1mm for the rest or just 1mm for everything? I would also like to know if there are better thermal pads? Also, have the temperatures improved for the gpu?
Gelid is a good brand to use. I would also pick 1mm for the thickness overall. The temperature varies from game to game. Some games such as Space Marine 2 really puts its components to work causing heat to rise. Never in the 90's though.
Last week i tried Kryosheet in my Lenovo Legion 5 laptop. Before Kryosheet i tried repasting with Kryonaut, but the temps were still bad. 100 degrees on cpu, and thermal throttling. After using Kryosheet my temperature dropped to 85 degrees, during 10 min run in Cinebench R23 (before it was hitting 100 degrees). My temperature curves also looks better than in this video in AIDA64. The temperature curve for my cpu climbs steadily instead of shooting right up, like in this video. I also tried using Kryosheet on the GPU with poor results. Temperature was fine, but hotspot hit 105 degrees, and thermal throttling again. I then switched back to Kryonaut on the GPU, and hotspot dropped to 86 degrees. (GPU 78 degrees)
nice job, kinda odd you didn't clean the spill off around the die but I assume you were hesitant to because a lot of people bust their gpu doing that. I did it myself (on a cheaper laptop) and it worked fine and easily 20c lower, used a few qtips and 100% cleaning alcohol. How is this particular paste/pad job holding up?
@@acuteaura no, 20c lower just repasting. I happened to clean all the parts that went off of the die. He actually mentions it in this video after I wrote my comment, he didn't clean it cause he didn't want to damage anything. But thermals are slightly worse when paste is spilled to the area surrounding the die, those parts cool off faster in plain air than being coated in paste that makes no contact
Does legion 7 2021 uses the same thickness of pads and would it be possible to use cooper sheet 0.5mm with 0.5mm pads with non conductive thermal paste ?
This laptop is getting clogged up pretty quickly when used for gaming and other high intensive workloads. I use compressed air every month to clean the fins and have already tore it apart twice in a year time to clean the fan. Fan blades are so dense which makes them almost impossible to clean thoroughly with compressed air only. That would resolve your overheating problem most likely but repaste have definetely made it even better.
It was pretty dirty considering I only run benchmarks on the machine. I was thinking maybe adding a filter along with a laptop cooler. the filter will black some airflow but by adding the fan this will make up for the loss.
7:09 I would do a little smaller squares. Cause most of it is gonna spill around cpu and gpu. Also when you look at GPU stress test "after" repasting - there could be a corelation between old and new GPU drivers, that makes it go more officient = higher temp.
hey Meanpooh, I hope you see this commet and you can answer me. We have the same PC, but one of my fans are broken. If i were to take it apart like yours, can you remove a fan? It looks to me like its stuck with the heatsink itself, is that true? Can you even seperate it?
@@Meanpooh Oh, well now im kinda nervous that I didn't get the right ones. I mean, I looked up everything about them and it seems its for my exact model, so I should be good I assume? I'll have to look into how i can figure this out, thanks a lot
I have a legion 5-15ach6h (RTX 3060 130W / R7 5800H) The thicknesses of the thermopads should be the same? I bought TG 8w/mK thermopads. I hope it will be ok.
Pretty sure you can,. Its no different than having extra thermal grease on a CPU or GPU. I would not go no higher than 2 as it will not squish like less viscous grease and my not hold a constant pressure when it gets up to temp, causing temps to increase.
I wonder if I should reorganize repasting using new thermal pads. Its been around 2years using Legion 5 rtx 3070 but while some games is loading it tends to go up 85° cpu temperature ocassional times while gpu is fine
@@Meanpooh If you say so to not ruin guarantee. I really was planning to repaste with Artic mx5 because of occasional stuttering that Cpu temperature goes up 85° by few seconds. I wouldnt imagine with bad optimized games that overheat much more. Btw im not who focus on max graphics setting and stopped playing actual triple A games due this
There have been many people who repasted this very machine and the temps have gotten worse. Some of them had to order a new heatsink assembly just to get it back to normal. If you have to, elevate the back of the machine a bit as to help with airflow. You should drop 3-5 degrees easy if you were flat before.
There's quite a serious mistep here. You should have informed your viewers that they'd need a different screwdriver (PH0) for the numbered screws rather than the PH00 used for the rest of the laptop. I learnt the hard way.
Wonder if you got real ptm as i have seen around 10-15 celsius drop on temps when aplying it. That stuff is almost as good as liquid metal if it is the real deal.
Someone somewhere said, that Lenovo uses ptm for the Legions at the factory. So if that's true, unless the factory has botched badly, there shouldn't be too big of a temperature drop.
I think this model of laptop and any other that is produced by Lenovo in the year '21, prefers a ptm7950 on a CPU and thermal paste on GPU. Because I got a big spikes on temperature on CPU which had a MX-5, but GPU stay at 60-78°c with the same thermal paste when playing the games.
Same lapie although i think i did a better job cleaning the old paste 🤣, but conclusion.. PTM is just another level. Ordered 80x80, 2 more lapies to go. Next will be f15 with heatsink deficiency
It really is. I cant wait to see the next developments in thermal paste. I wish the manufacturers will just use thicker heat sinks and larger fans. If this is implemented I can see people complaining that their gaming laptop is too heavy.
@@Meanpooh applied to the f15 with 1650ti, the cheapest line of the tuf series, temps with peak around 85 full load, i5 10300h at 4.2.. not even the original paste does this..
I just want to share with you guys, there is other problem with the dust that not only the dust that stuck on the fan, but the dust that stuck on the heatsink inside. even though the fan is clean, if you don't get rid the dust that stuck on the heatsink inside, the hot air will not get out from the laptop, it will make you laptop overheat.
@@Stardomplay You have to detach the fan from the heat pipe, then inside it you can brush it. 1. remove the heatpipe from the motherboard, becareful because legion 5 fan and the heat-pipe is merged. 2. remove all the screw of the fan, detach the fan from heat pipe 3. brush the inner side of the heatsink 4. then re-assemble
@@pocketprime hey man, actually i have this problem, my legion overheats so much to the point it power throttles my gpu to 70w and its a rtx 3070 130w model. I replaced the thermal pads with owltree 12.6w/k 1mm and it made it worse. Can you tell me if the adwits 6.0w/k pad is good? Its said to be softer than the owltree one.
@@renegadesg018 I don't know the quality of thermal pad that you mention. I don't replace my thermal pad, I just replace the thermal paste using deep cool z3 (1.134 W/m-K) on CPU and GPU. Then clean the dusk on the fan and the inner side of the heatsink.
I have heat problems on a similar model too (3060 5600h one); I'll start by cleaning the fans but if that's not enough I might change the grease and keep the pads if they're fine Think mx4 would work or should I really go honeywell? Kinda hard to get in eu
MX4 will work but just know that many people get worse temps after repaste on this model. I know you have a different one but check around just to make sure.
Hi I have same laptop it's been a 2 year but I have used it only 40 times just to watch TH-cam for maximum 3 hour... No gaming./ the cpu temp is 55c average and gpu 45c. Should I repaste it? You video is helpful and it'll save me some great money thnxz
@@Messmers_flame yes I have m1 pro 16 16/512 it's a good laptop but boring laptop I used that in college now I use it in office. But what l5 pro can do mac won't be able to do it. Cause I don't want to kill my ssd.
If they are fairly new, no. Over 2 years with heavy gaming, yes. Please note that a lot of people got worse temps after a repaste with this machine. Some have had to reorder the whole heatsink to get it back to normal. I'm playing Remnant 2 and my temps are just barely hitting 80 staying mostly in the 70's for both CPU and GPU. Will post video later.
@@Meanpooh interesting! Alternatively can I replace pads with all paste (even those other spots where thermal pads are applied)? Given that pads have worse results compare to the paste?
:-). Nope thy will not come out. There is a small piece of plastic on the underside that prevents it from dislodging fully. It may be metal. I've heard of people slightly turning the screws back to get lower temps but what if the locking piece is causing the problem? What if it's adjusting out of spec as the screw is being loosened? Something to think about.
@@EvilijoUKcan you share a gameplay video on it on how the temps now at max boost, run at performance mode and Lenovo vantage software GPU oc max than share some videos with msi afterburner

how did it go?
thanks for this. lenovo couldnt fix my temps after 2 atrempts
You are welcome!
did the gpu temps go down by any chance?
Hello, Can I put doble thermal ptm 7950? I meam one above the another?
Pretty sure you can,. Its no different than having extra thermal grease on a CPU or GPU. I would not go no higher than 2 as it will not squish like less viscous grease and my not hold a constant pressure when it gets up to temp, causing temps to increase.
Is 4x4cm hw ptm9750 enough for 5800h&3060 die size?
Medium size is enough for a laptop for both CPU and GPU.
I wonder if I should reorganize repasting using new thermal pads. Its been around 2years using Legion 5 rtx 3070 but while some games is loading it tends to go up 85° cpu temperature ocassional times while gpu is fine
85 degrees is fine. If thats as high as your hitting, I wouldn't touch it.
@@Meanpooh If you say so to not ruin guarantee. I really was planning to repaste with Artic mx5 because of occasional stuttering that Cpu temperature goes up 85° by few seconds. I wouldnt imagine with bad optimized games that overheat much more. Btw im not who focus on max graphics setting and stopped playing actual triple A games due this
There have been many people who repasted this very machine and the temps have gotten worse. Some of them had to order a new heatsink assembly just to get it back to normal. If you have to, elevate the back of the machine a bit as to help with airflow. You should drop 3-5 degrees easy if you were flat before.
@@Meanpooh I always use laptop stand also clean vents often if its necessary wich help a bit. I better leave it as is. Thnx for your suggestion
You are welcome.
There's quite a serious mistep here. You should have informed your viewers that they'd need a different screwdriver (PH0) for the numbered screws rather than the PH00 used for the rest of the laptop. I learnt the hard way.
The cooling system and the fans must also be completely disassembled in order to properly clean the radiators and fans. Trust me, this works wonders.
Did u applied ptm 7950 what are your results
Wonder if you got real ptm as i have seen around 10-15 celsius drop on temps when aplying it. That stuff is almost as good as liquid metal if it is the real deal.
Someone somewhere said, that Lenovo uses ptm for the Legions at the factory. So if that's true, unless the factory has botched badly, there shouldn't be too big of a temperature drop.
the gpu temp increses because the cpu temp is better now and the fan speed is lower
Can you explain a bit on it, why is that ?
I think this model of laptop and any other that is produced by Lenovo in the year '21, prefers a ptm7950 on a CPU and thermal paste on GPU. Because I got a big spikes on temperature on CPU which had a MX-5, but GPU stay at 60-78°c with the same thermal paste when playing the games.
Same lapie although i think i did a better job cleaning the old paste 🤣, but conclusion.. PTM is just another level. Ordered 80x80, 2 more lapies to go. Next will be f15 with heatsink deficiency
It really is. I cant wait to see the next developments in thermal paste. I wish the manufacturers will just use thicker heat sinks and larger fans. If this is implemented I can see people complaining that their gaming laptop is too heavy.
@@Meanpooh applied to the f15 with 1650ti, the cheapest line of the tuf series, temps with peak around 85 full load, i5 10300h at 4.2.. not even the original paste does this..
@@Meanpooh i don't think gamers really care about the weight.. maybe use silver instead of cooper .. a better design perhaps
I just want to share with you guys,
there is other problem with the dust that not only the dust that stuck on the fan, but the dust that stuck on the heatsink inside.
even though the fan is clean, if you don't get rid the dust that stuck on the heatsink inside, the hot air will not get out from the laptop, it will make you laptop overheat.
So how do we get that dust out pocket prime?
@@Stardomplay You have to detach the fan from the heat pipe, then inside it you can brush it.
1. remove the heatpipe from the motherboard, becareful because legion 5 fan and the heat-pipe is merged.
2. remove all the screw of the fan, detach the fan from heat pipe
3. brush the inner side of the heatsink
4. then re-assemble
@@pocketprime hey man, actually i have this problem, my legion overheats so much to the point it power throttles my gpu to 70w and its a rtx 3070 130w model. I replaced the thermal pads with owltree 12.6w/k 1mm and it made it worse. Can you tell me if the adwits 6.0w/k pad is good? Its said to be softer than the owltree one.
@@renegadesg018 I don't know the quality of thermal pad that you mention.
I don't replace my thermal pad, I just replace the thermal paste using deep cool z3 (1.134 W/m-K) on CPU and GPU. Then clean the dusk on the fan and the inner side of the heatsink.
Thermal pad 1mm all this work now?
What thickness is the blue PTM?
Are you using gelid 0.5 or 1 mm ?
1mm
Hi this is 1mm or 0.5 mm? Pad for v rams?
1.0 mm
Hello. When you replaced your old factory thermal pads, you said: I keep it, in case new ones won't work. So after 11 months how it works?
The L5P is still working fine. No issues.
@@MeanpoohThanks for responding. I actually already have some experience with gelid: used it for ssds, but was curious about chips.
so thermal pads is better than thermal paste when applied on the cpu/gpu on a laptop? I need clear answer pls XD
Only put thermal paste/grease on CPU and GPU. Thermal pad on everything else.
@@Meanpooh wont thermal pads only do the job for cpu and gpu
I have heat problems on a similar model too (3060 5600h one); I'll start by cleaning the fans but if that's not enough I might change the grease and keep the pads if they're fine
Think mx4 would work or should I really go honeywell? Kinda hard to get in eu
MX4 will work but just know that many people get worse temps after repaste on this model. I know you have a different one but check around just to make sure.
THERMAL GRIZZLY Kryonaut
Did you ever use the mx4 repaste?
@@ok_monad i repasted with thermal grizzly kryonaut and cpu temps improved to 85c fom 103c and after 3 months it back to 104c now
hello @Meanpooh hows the temp now?
Just look at any other video I posted after this one.
gpu temps are higher because the gpu side fan was really dirty honestly my laptop could probably use a cleaning like that
So far everything is good. Made an update and everything is pretty much back to normal. th-cam.com/video/4s6meK9RCys/w-d-xo.html&ab_channel=Meanpooh
@@Meanpooh hey. what did you do to fix it? I repasted and my GPU temps are higher than normal with PTM.
Hi I have same laptop it's been a 2 year but I have used it only 40 times just to watch TH-cam for maximum 3 hour... No gaming./ the cpu temp is 55c average and gpu 45c. Should I repaste it?
You video is helpful and it'll save me some great money thnxz
No, I would not. Your laptop seems to be displaying great thermals.
@@Meanpooh thnxz
sell that. you should have bought mac air or something.
@@Messmers_flame yes I have m1 pro 16 16/512 it's a good laptop but boring laptop I used that in college now I use it in office. But what l5 pro can do mac won't be able to do it. Cause I don't want to kill my ssd.
@@Messmers_flame but nothing comes close to the desktop
ty man for detailed cpu and gpu measurements
Do I have to replace those thermal pads? I mean besides GPU and CPU should I bother with the stock thermal pads that are elsewhere in the area?
If they are fairly new, no. Over 2 years with heavy gaming, yes. Please note that a lot of people got worse temps after a repaste with this machine. Some have had to reorder the whole heatsink to get it back to normal. I'm playing Remnant 2 and my temps are just barely hitting 80 staying mostly in the 70's for both CPU and GPU. Will post video later.
@@Meanpooh interesting! Alternatively can I replace pads with all paste (even those other spots where thermal pads are applied)? Given that pads have worse results compare to the paste?
Only use pads. Do not use paste as an alternative. Will most likely be the worse mistake you could make.
@@Meanpooh just to clarify (for myself) paste on gpu/cpu yes or no?
Yes, that is correct.
Those big screws on the heat sink tricked me real good. I thought it was removable because I couldnt take out those screws...
:-). Nope thy will not come out. There is a small piece of plastic on the underside that prevents it from dislodging fully. It may be metal. I've heard of people slightly turning the screws back to get lower temps but what if the locking piece is causing the problem? What if it's adjusting out of spec as the screw is being loosened? Something to think about.
I prefer the Gelid thermal paste.
you haave to wait few weeks and then compare with stock
FIRST sup Meanpooh can you do a benchmark on Atomic Heart using the 2020 Acer Nitro 5 you have please thank you.
If you mean 1650 Ti, I have already made one.
will it void my warranty by doing it by self
If you are under warranty I would contact Lenovo first to see what they can do. If you are out of warranty then it shouldn't hurt.
Done 4 repastes in a matter of 6 weeks on my Legion 5 rtx 3070 (had it for almost 2 years), still not happy about results 🤣
Done repastes with what PTM7950 ?
@@Asura0089 Nope. Decided to go all in and got a tube of Conductonaut, now I'm happy with it 😅
@@EvilijoUKcan you share a gameplay video on it on how the temps now at max boost, run at performance mode and Lenovo vantage software GPU oc max than share some videos with msi afterburner
@@EvilijoUKchange to ptm 7950. It’s the stock
@@Scronx-mc3uj Liquid metal is even better than that
tytytytyty 🙌
He used 1mm thickness.
круто !!!✔
Спасибо
@@Meanpooh 😊
I recommend you try Honeywell PTM7950 and Honeywell HT10000
Hmm Honeywell HT10000......I'm curious. Thanks for the heads up.
