Just wanna shout you out man....tried this today and it worked like a charm. Although it took me 2 hours to do it(just cause I was being extra careful) but in the end it was worth it, temps dropped around 20 degree C(used Arctix Mx4). Also, in my piece there were just 6 spring screws not 7 inside. If it was not for this video then I wouldn't have even tried to do it. So, thanks again. Also, in 2022 if someone is confused between Mx4 and Mx5 then go with 4 as its better and cheaper.
Great video, thanks for putting this up. I would suggest to anyone trying, from personal experiance, ALWAYS start with disconnecting the battery as the very 1st step. Use a plastic tool, never a metal one! :)
Went a little overboard on the thermal paste but overall nice video. I don't think any method works best, I just use the pea method. But too much thermal past can hurt performance as well. You want just barely enough to cover the entire dye, which when the block is screwed down the paste will spread. Too much paste and the heat just has more material it has to go through to be removed. Literally the least amount in order to cover it all is ideal, no air the heat has to travel through, but no excess paste as well
Replaced my thermal paste on my 2year old y540, 9300h, 1660 ti since I had massive heat problems lately. Been gaming alot more than I used to and saw a constant increase in temperature. Undervolting my CPU(ThrottleStop -150mV) and GPU(Afterburner 0.900V@1700MHz curve) just didn't cut it so I found your video. Temperature went down about ~20degree Celsius, I couldn't believe it. Used my 5+year old arctic silver 5. Thanks for the good video, so glad I finally have good temps again. Hopefully I didn't put to much thermal paste on it. Think I went a bit overboard after rechecking your video lol. Well time will tell
My Y540 was a bit more of a pain to get open as the back cover came in 2 pieces and I first had to remove the HDD-slot to remove the last part. Great tutorial! There was so much dust in the fans, ,I'm surprised they still turned
Changed thermal paste and upgraded to 32 GB ram. Lowered GPU temps by 40°C, CPU temps by 10°C - CPU still spiking 95°C sometimes..? TYSM for the tutorial!
thanks for this, I just replaced the thermal pads in my y740 this way. Somewhat different internals but close enough that I could follow this. I opted to use knockoff thermal pads of the same model as stock, and my load temps have come down at least 10c. Thanks!
The only thing I would add to this is to put the thermal paste in the shape of an X. This ensures maximum coverage. The single line won't cover the thermal paste until the edges. If you take a glass slide and press down on the thermal paste in the two different shapes(X and a line), you'll see that the X shape covers the CPU/GPU completely.
When I recorded the video I wanted to make sure its easy and simple for everyone to follow. The main reason i chose a line instead of X or 5 dot arrangement is that it has less chance of messing up..
@@SaMiNM fair enough. It's not that difficult though. An X is two lines and 5 dots is easier. Just my opinion. Great video, though! Easy to follow, no talking, everything on the screen and easy to read. Loved it. Saved it and sharing it.
With low viscosity pastes (which I don't use anymore on direct-die, i switched to high viscosity and PTM7950) the X or manual spread is indeed recommended. If a small part of the die remains uncovered it might fry the chip due to a very high hotspot on that area.
Fair warning: Don't do this if your laptop is new. If yours is thermal throttling too often with lowish load, take it to official warranty, they probably forgot/did not fully pasted your cpu or gpu. I say this because the thermal paste lenovo used is pretty good and actually outperform MX4. This is from actual personal experience, had to open it up again and replace paste with PTM7950 pads to see any actual minor improvement compared to stock paste.
Trying to unscrew the heatsink, but the screws were so stubborn and wouldn't turn. Even trying applying pressure, but still results with the screwdriver jumping off the screw and possibly striped the screws. My screwdriver may not be perfect for this one. Im using a jakemy screwdriver and the head was a bit sharper. Probably have to take to the third party or official service shop just to be safe and probably won't ended up with stripped screws
UPDATE: After a bit of a miracle, i attempt to unscrew the stubborn screw again. This time even though a bit striped, i finally managed to unscrew. The procedure runs smoothly. Well unplugging the battery is very hard so i gave up on that. The fan plugs seems delicate so i wouldn't dare to force pull it. Just applying the canned air spray and replace the paste. And done
Great video pro quick question should i use thermal paste material of metal that conduct heat or i use carbon or ceramic ? It depends on cpu and gpu is it in lenovo y540 connected directly on the motherboard?
For doing thermal repaste it's fine. If you want you could disconnect the battery you can but the connector is a really difficult one to remove and is easy to break which is something you don't want. Another way is to ground yourself on doing it where here I was grounded to the table....
Thanks for this brother! My y740 doesn't seem to go above 80c whilst gaming or in my DAW but I've had the idea to add some arctic MX-4 to it just to see if I can maximize it even more... ;) blessings!

@@Mort_Mort You can undervolt CPU by cca 0,5-1,0V max, I use 250mV, that is enough....but if you undervolt cache by more than 100mV, then the system can crash. Nothing fatal tho

How is the MX 4 holding? Did it pump out .. or are temps high again after this repaste you did? My laptop when gaming is 90+ C ... I ordered Arctic MX-5 and gonna repaste it soon and a bit worried.

How often should we reapply the thermal paste? I bought a 2nd hand y7000 it's a 2019 model I think the last owner did not reapply the thermal paste yet. Playing ac odyssey my thermal can reach 70°c on room temp while using an electric fan for ventilation. Is this still fine?
Hey can i use hand sanitizer which contains ( isopropyl, purified water , triethanolamine, Acylate copplymer , perfume ), i have ordered isopropyl but is haven’t reached yet i donno why its been a month , and i am done waiting. Pls reply
I will say I don't recommend using the hand sanitizer as it contains not just alcohol but chemical mix which will not evaporate away and leave residues on the chip which can stain it and make the surface difficult for thermal paste to spread evenly and conduct heat properly. I say wait for the 99% pure alcohol as it is suitable for this application than rather risking damaging a 1000 dollar laptop to save a buck...
I think yes you need to change it bc air bubbles can limit the contact between heat sink and cpu , did you check the cpu gpu thermal after you put it together?
Lowered by around 6 to 8℃ and the frequency of fans spinning up decreased by a lot.. Also I had observed that spreading the thermal paste evenly before placing the heatsink over it has been the most effective one where it dropped by 12℃.
@@nomadstidbits Enthusiast grade pastes (Thermal Grizzly Kryonaut)do dry out faster than OEMS (MX-4) and are better at conducting heat because of it. But in case of these two its in the negligible scale of effect for an normal user and only their price difference is the major factor.
"my fan spins for a second and it stopped after that"- It didn't spin after that at all ?? If it did, then its normal only cuz when starting up the fans spins up for a few seconds just to check if its working in the same way as your keyboard lights turn on for a second when turning on. Then the fans will only kick into action when the temps go high.. If it didn't spin after-all then I say you have not connected the fan cables properly back to the socket which you can redo and it will be all working back to normal.
Hey thanks for the video i wanted to ask you used artic mx4 right did it seep out of the CPU dye?? I saw quite a lot people saying the paste doesn't hold for more than a week and seeps out and boom thermal throttling again
Yes, it will lose around 10% of the moisture in a week but its common only all thermal pastes are made like that so they flow easily and spread evenly on the die when pressure is applied. After that it stays consistent for 6 months or 1 year depending upon the usage. Thermal paste mostly start to powder when temps go above 90 to 95°C and also how long it stays in those temp range.
I think it would be enough to re-paste the GPU and CPU once. I would recommend Thermal Grizzly only if u do heavy intensive work [ rendering or long high intensive gaming sessions for hours ] on you laptop and in all other situation MX-4 work great and also costs less. Also extract from web : "Unless your laptop has a desktop processor (yes, they do exist) and a discreet graphics chip (if it has anything Nvidia on it, or an Intel with an AMD processor would also have a discreet unit in most likelihood).. then yes, 1G should be more than sufficient to re-paste your laptop a time or two." - Quora
@@alien6874 When I did it for the very first time they screws had glue on their treads which made it tough but after a little bit of force it came out easily.. If you had applied like great force and still not coming out then don't try too much as you can wear out the cavity cut on the screws which you don't want so I suggest you giving it once to a store for repasting so that once they loosened the screws the next time you can do it easily by yourself...
Try to replace the broken fan with a new replacement one and check which side it is as both sides fans dimension are different. If you don't fell confident doing these try giving the laptop to service centers as they will help in these cases.
after how much time it is recommended to clean the fans and replace the thermal paste . my y540 gonna complete 2 years soon and my facing lag in performance and the performance in game is also decreased
Stopped working meaning it doesn't spin at all ? or spins super slow ? If it doesn't spin at all means its motor maybe dead and that fan needs to be replaced. The thing with disassembling the fan casing is that its extremely difficult as its casing is bend into shape rather than screwed so i won't recommend you try to dissemble the fans.
I also have this issue and for me the cable adapter heats up a lot when charging too. I think it could be due to an misaligned pin the charging socket and can be fixed by replacing the charging port.
I have a screwdriver set and the one which seems to work I used... It's a normal Philips screw as much I know But the dimensions of screw I know which is M2.0X8 M2.0X4 When u see it u will easily understand it
If it's a new one and it's reaching 90s then it could be due to a bad thermal paste used by the manufacturer or could be due to uneven applying of thermal paste when it was assembled as 1000s are assembled one after other and they might not have done it properly.... Idk much about the temp range of an idealpad but check online and if it off then consider doing a repaste.. It will similar as this only....
Good day sir, I have legion 5 amd, ryzen 5 4600h with gtx 1650 Ti, my processor average thermal is 39, when in gaming it recaches 60, I don't have external fans, I only have laptop stand for it to lift, also its warm here in my place since its a trophical country, do u think my temps are okay?
39℃ at idle and 60℃ during gaming is fine only. Just a small lift is enough while gaming so that there is smooth airflow for cooling. Just keep an eye out in the long run for any thermal throttling and consider undervolting it for better performance and cooling...
@@SaMiNM thank youu, i don't like to undervolt it hehe, I might mess things up, i have done something to lower my temps without undervolting ua-cam.com/video/8P-lfILWu-k/v-deo.html
Hey, I got the same laptop and suddenly temperatures on DESKTOP went nuts, normally they were like 45 degrees on average and now they are average 60 degrees. Do you think it is thermal paste fault and that I should change it? It was stock so maybe that would be the problem?
The average thermal paste lifetime is 1 year but with extensive heat creating tasks like gaming it will be reduced further. So if it's an old paste consider repasting it.
I had like 65-75 degrees with my cpu and gpu without any problem but after a ram upgrade (I added an 8gb stick) the cpu reaches 95 degrees. Is this normal? Should I repaste or not?
Does your new ram's voltage match to the old ones if it doesn't i think it will cause some heat issues. Always try to have same memory on both slots for the best performance.
haii can I know does it the thermal paste need cure time for it to work effectively? since I just repaste my laptop using mx-4 and then I notice the temperature rising not like before either on idle or while gaming
@@SaMiNM it got worse I think. before my temperature on idle was below 40°c for gpu and 45°c for cpu and for gaming was 50 c for gpu and 60 for cpu. After repaste for idle become 45 c for gpu and around 50 - 52 for cpu. While for gaming it become 60°c for gpu and 80-85 for cpu.
@@kingspartan4008 I think it could be due to either one of these reasons: 1. The paste is not spread uni-formally. 2. Not enough thermal paste was used. 3. Paste used was expired or hardened. This could be fixed when you re-paste again but this time try to follow these step too: 1. Make sure you clean off the residue of the old paste properly or else the new paste can't make proper contact with die and heat sink and also causing it to spread unevenly. Also try to clean the paste in the gap. 2. Before applying the thermal paste the tube of paste in the nozzle will be dry so squeeze that bit out and when you get the smooth consistent flowing paste use that for pasting. 3. Try spreading the paste out evenly on the surface with the nozzle itself and the edges so that it covers the entire surface and the gaps. Putting too much paste on a socket generally won't hurt thermal performance, because the act of tightening down the cooler squeezes out the excess. Too little paste is bad, but anything above the minimum threshold will have the same effect once the cooler is tightened down.
I've had my y540 since a year now I'm having decent frames in most games but my CPU and GPU barely heat up (rarely reach 70°) even during games (fortnite 65° farcry5 75°) I haven't upgraded anything except the ram Should I be doing a repaste or something? I think this performance is better than what is expected of it but I really don't know
@@Danish-kd7og Yeah i5 does run cooler than the i7 used here and its normal only. Check if yours show any thermal throttling while gaming, if so consider changing the paste nearby if you want to maximize the performance. If there is none then do it every 1 to 2 year gap to keep it cooled properly.
Actually I have watched benchmarks on UA-cam and seen others y540 and mine is running unusually cold (it wasn't for the first few months) . And never throttles. So for now I shouldn't be changing it right? (Until it starts heating)
I will say I don't recommend using 70% alcohol as the other 30% will be water and other chemical mix which will not evaporate away and leave residues on the chip which can stain it and make the surface difficult for thermal paste to spread evenly and conduct heat properly. I say get the 99% pure alcohol as it's really cheap and is suitable for this application than rather risking damaging a 1000 dollar laptop to save a buck...
In general, maintainance and upgrade such as re application of thermal paste should not void the warranty as long as no damage incurred during and after the process. Also here you can see their are no warranty stickers on any screws that are on the heatsinks, fans, or casing. If u look near the GPU you will see a screw with warranty sticker if you remove those then only your warranty will be voided. This is however, regional as it may apply differently on your location.
wow, i repaste my Legion 5 and my CPU temp went from 94C down to 55C, and the RTX 3070 went from 66C down to 37C, truly amazing, i can't believe it!

Hey can i use hand sanitizer which contains ( isopropyl, purified water , triethanolamine, Acylate copplymer , perfume ), i have ordered isopropyl but is haven’t reached yet i donno why its been a month , and i am done waiting. Pls reply
I will say I don't recommend using the hand sanitizer as it contains not just alcohol but chemical mix which will not evaporate away and leave residues on the chip which can stain it and make the surface difficult for thermal paste to spread evenly and conduct heat properly.
I say wait for the 99% pure alcohol as it is suitable for this application than rather risking damaging a 1000 dollar laptop to save a buck...
Ty for your video bro
i have question
if we open heatsink for just a fan repelacement should we change the thermal paste on GPU and CPU ?
I think yes you need to change it bc air bubbles can limit the contact between heat sink and cpu , did you check the cpu gpu thermal after you put it together?
@@llkl0204 actually i didn't open the laptop yet , but yeah you are right
Ty man
After repaste how are the temps?
Is the difference in temps are satisfying?
Do a follow-up video
it will be helpful
Good content
Lowered by around 6 to 8℃ and the frequency of fans spinning up decreased by a lot..
Also I had observed that spreading the thermal paste evenly before placing the heatsink over it has been the most effective one where it dropped by 12℃.
It's ok to use 12.5 W/mk Thermal Grizzly Kryonaut for gaming 5-9 hours per day ?
Thermal Grizzly Kryonaut is a really good thermal paste.. It will be a great choice.
@@SaMiNM it have gret thermal conductivity but does kryonaut wearout faster than mx4?
@@nomadstidbits Enthusiast grade pastes (Thermal Grizzly Kryonaut)do dry out faster than OEMS (MX-4) and are better at conducting heat because of it. But in case of these two its in the negligible scale of effect for an normal user and only their price difference is the major factor.
thanks a lot!!
You're welcome!
Gelid GC Extreme is claiming less pump out effect anyone used them before? What's best for Y540 (9300h and 1660Ti)?
Bro I have an issue my charging pin slim type is getting too hot can't even touch it I don't know what to do
Thank you for the step by step guidance, but after turning on, my fan spins for a second and it stopped after that, any fix?
"my fan spins for a second and it stopped after that"- It didn't spin after that at all ??
If it did, then its normal only cuz when starting up the fans spins up for a few seconds just to check if its working in the same way as your keyboard lights turn on for a second when turning on. Then the fans will only kick into action when the temps go high..
If it didn't spin after-all then I say you have not connected the fan cables properly back to the socket which you can redo and it will be all working back to normal.
Hey thanks for the video i wanted to ask you used artic mx4 right did it seep out of the CPU dye?? I saw quite a lot people saying the paste doesn't hold for more than a week and seeps out and boom thermal throttling again
Yes, it will lose around 10% of the moisture in a week but its common only all thermal pastes are made like that so they flow easily and spread evenly on the die when pressure is applied. After that it stays consistent for 6 months or 1 year depending upon the usage. Thermal paste mostly start to powder when temps go above 90 to 95°C and also how long it stays in those temp range.
What thermalpaste should i use?
Hey Samin, will 1gm of thermal Grizzly Kryonaut would be enough for this. Or should I go with Arctic MX-4 .
I think it would be enough to re-paste the GPU and CPU once. I would recommend Thermal Grizzly only if u do heavy intensive work [ rendering or long high intensive gaming sessions for hours ] on you laptop and in all other situation MX-4 work great and also costs less.
Also extract from web :
"Unless your laptop has a desktop processor (yes, they do exist) and a discreet graphics chip (if it has anything Nvidia on it, or an Intel with an AMD processor would also have a discreet unit in most likelihood).. then yes, 1G should be more than sufficient to re-paste your laptop a time or two." - Quora
@@SaMiNM thanks, I do game a lot
dont you have to deconnnect the battery or something to be sure to not hurt yourself?
yes you should unplug the battery connector first
А термопрокладки?
which philips head you use to loose the Heatsink? ph0 or ph1
Did you have any issues removing heatsink screws the first time you repasted?I stripped all of my y740 screws because they were locked in place
No they were smooth as butter...
How did u take those out? The screws in mine are hard af
I am facing same problem out of 7 screws 2or3 came off easily but rest are hard. Help me if u resloved your problem.
@@alien6874 When I did it for the very first time they screws had glue on their treads which made it tough but after a little bit of force it came out easily.. If you had applied like great force and still not coming out then don't try too much as you can wear out the cavity cut on the screws which you don't want so I suggest you giving it once to a store for repasting so that once they loosened the screws the next time you can do it easily by yourself...
@@SaMiNM 4ap mm kk po
Really helpfull
Tnx
I have a problem. The fans are not spinning but even before the fix i think they weren't spinning
Try to replace the broken fan with a new replacement one and check which side it is as both sides fans dimension are different. If you don't fell confident doing these try giving the laptop to service centers as they will help in these cases.
after how much time it is recommended to clean the fans and replace the thermal paste . my y540 gonna complete 2 years soon and my facing lag in performance and the performance in game is also decreased
You forget to remove the battery .. Its safe to disconnect battery before doing these stuff..
Mine is coming tomorrow, will stock thermal paste be ok? I got the i7 9750h and 2060
Same model used in the video. Check the temps at idle and gaming if its too high consider changing the paste and under-volt it.
When I did the test the fans spinned at startup then stopped when logged in windows, is this normal for fans to stop spinning when laptop is on
How much should we use full tube or a bit
hey bro i have a y540 and the left fan stopped working, can u make a tutorial on how to lube it?
Stopped working meaning it doesn't spin at all ? or spins super slow ? If it doesn't spin at all means its motor maybe dead and that fan needs to be replaced. The thing with disassembling the fan casing is that its extremely difficult as its casing is bend into shape rather than screwed so i won't recommend you try to dissemble the fans.
You forgot to unplug the main baterry 🤦♂️
What is the tybe of the thermal paste?
Hey man I have problems with the charger it like keeps disconnecting until I place it in certain position what's the problem?
I also have this issue and for me the cable adapter heats up a lot when charging too. I think it could be due to an misaligned pin the charging socket and can be fixed by replacing the charging port.
Mx4 still recommended?
i dont have isopropyl alcohol what can i use to clean, thank you
I used spirit alcohol once and had no problems, but isopropyl alcohol will be much better - you can buy it online
Thank you ❤️
Bro what screwdriver did u use for the heatsink screws? I can't get them off
Philip's head screws.
Same problem here , tell me if your problem is resolved ,if so which screwdriver did you use. I want to buy.
Try getting a better screwdriver, cuz I went to get a cheap ass one but it was only able to open the top part of the laptop but not the bottom one.
Temp difference?
What screw type needed for the heat sink screws? Ph000 or Pz0 or anything else?
I have a screwdriver set and the one which seems to work I used...
It's a normal Philips screw as much I know
But the dimensions of screw I know which is
M2.0X8
M2.0X4
When u see it u will easily understand it
worth repasting a 1 month old lenovo ideapad gaming 3? the 10th gen intel cpu is running in the 90s during gaming
If it's a new one and it's reaching 90s then it could be due to a bad thermal paste used by the manufacturer or could be due to uneven applying of thermal paste when it was assembled as 1000s are assembled one after other and they might not have done it properly....
Idk much about the temp range of an idealpad but check online and if it off then consider doing a repaste..
It will similar as this only....
Good day sir, I have legion 5 amd, ryzen 5 4600h with gtx 1650 Ti, my processor average thermal is 39, when in gaming it recaches 60, I don't have external fans, I only have laptop stand for it to lift, also its warm here in my place since its a trophical country, do u think my temps are okay?
39℃ at idle and 60℃ during gaming is fine only. Just a small lift is enough while gaming so that there is smooth airflow for cooling. Just keep an eye out in the long run for any thermal throttling and consider undervolting it for better performance and cooling...
@@SaMiNM thank youu, i don't like to undervolt it hehe, I might mess things up, i have done something to lower my temps without undervolting ua-cam.com/video/8P-lfILWu-k/v-deo.html
What temps did you observe afterwards?
Lowered by 6 - 8℃ and the frequency of fans spinning up decreased by a lot and while gaming no thermal throttling was detected after this..
Hey, I got the same laptop and suddenly temperatures on DESKTOP went nuts, normally they were like 45 degrees on average and now they are average 60 degrees. Do you think it is thermal paste fault and that I should change it? It was stock so maybe that would be the problem?
The average thermal paste lifetime is 1 year but with extensive heat creating tasks like gaming it will be reduced further. So if it's an old paste consider repasting it.
I had like 65-75 degrees with my cpu and gpu without any problem but after a ram upgrade (I added an 8gb stick) the cpu reaches 95 degrees. Is this normal? Should I repaste or not?
Does your new ram's voltage match to the old ones if it doesn't i think it will cause some heat issues. Always try to have same memory on both slots for the best performance.
haii can I know does it the thermal paste need cure time for it to work effectively? since I just repaste my laptop using mx-4 and then I notice the temperature rising not like before either on idle or while gaming
U mean your temps didn't decrease after doing re-paste ? or it got worse ?
@@SaMiNM it got worse I think. before my temperature on idle was below 40°c for gpu and 45°c for cpu and for gaming was 50 c for gpu and 60 for cpu. After repaste for idle become 45 c for gpu and around 50 - 52 for cpu. While for gaming it become 60°c for gpu and 80-85 for cpu.
@@kingspartan4008 I think it could be due to either one of these reasons:
1. The paste is not spread uni-formally.
2. Not enough thermal paste was used.
3. Paste used was expired or hardened.
This could be fixed when you re-paste again but this time try to follow these step too:
1. Make sure you clean off the residue of the old paste properly or else the new paste can't make proper contact with die and heat sink and also causing it to spread unevenly. Also try to clean the paste in the gap.
2. Before applying the thermal paste the tube of paste in the nozzle will be dry so squeeze that bit out and when you get the smooth consistent flowing paste use that for pasting.
3. Try spreading the paste out evenly on the surface with the nozzle itself and the edges so that it covers the entire surface and the gaps.
Putting too much paste on a socket generally won't hurt thermal performance, because the act of tightening down the cooler squeezes out the excess. Too little paste is bad, but anything above the minimum threshold will have the same effect once the cooler is tightened down.
@@SaMiNM Alright thanks for the steps. I will try it after this.
what screwdriver you use for the heatsink??
Philips ones
Can i use water instead of alcohol
1000% No. Try to avoid moisture I would say...
Greater than 90% Alcohol minimum
I've had my y540 since a year now
I'm having decent frames in most games but my CPU and GPU barely heat up (rarely reach 70°) even during games (fortnite 65° farcry5 75°)
I haven't upgraded anything except the ram
Should I be doing a repaste or something?
I think this performance is better than what is expected of it but I really don't know
Is it the i5 version ?
@@SaMiNM yes, the i5 variant and by decent frames I mean near consistent 60 in most games
@@Danish-kd7og Yeah i5 does run cooler than the i7 used here and its normal only. Check if yours show any thermal throttling while gaming, if so consider changing the paste nearby if you want to maximize the performance. If there is none then do it every 1 to 2 year gap to keep it cooled properly.
Actually I have watched benchmarks on UA-cam and seen others y540 and mine is running unusually cold (it wasn't for the first few months) . And never throttles.
So for now I shouldn't be changing it right? (Until it starts heating)
@@Danish-kd7og Did you undervolt it ?
can i do this safetly if battery is charged?
Yeah after Shutting it down..
is it safe ?
Can I use regular alcohol? 70% alcohol
I will say I don't recommend using 70% alcohol as the other 30% will be water and other chemical mix which will not evaporate away and leave residues on the chip which can stain it and make the surface difficult for thermal paste to spread evenly and conduct heat properly.
I say get the 99% pure alcohol as it's really cheap and is suitable for this application than rather risking damaging a 1000 dollar laptop to save a buck...
Does anyone knows how to set fans at maximum speed?
Go to Lenovo Vantage and set Cooling mode to Performance Mode and your fans will ramp up to its maximum speed when it gets hot...
Does repasting void warranty
In general, maintainance and upgrade such as re application of thermal paste should not void the warranty as long as no damage incurred during and after the process.
Also here you can see their are no warranty stickers on any screws that are on the heatsinks, fans, or casing. If u look near the GPU you will see a screw with warranty sticker if you remove those then only your warranty will be voided.
This is however, regional as it may apply differently on your location.
How long does the thermal paste last? How often should I reapply?
Six months
thx
