MSI GS66 Stealth Thermal Paste Guide

Highly requested thermal paste guide for the MSI GS66 Stealth. Just wanted to clarify the "pink stuff" is actually thermal pads, you can get replacements for those online if you feel you need them.
Suggested thermal paste: www.amazon.com...
Thanks for all of your support on my videos!
Hopefully this helps you guys.
Please feel free to leave feedback and suggestions down in the comments!

I don't normally comment on KZbin videos, but this was excellent with exceptional attention to detail. Thank you.

[@NexusTechRepair]

Thank you so much

[@ИгорьАлексеев-э6в]

There is a little hole a bit left from the center on the back plate. There is a shutdown button underneath it, which can be pressed by a pin or a clip. It's necessary for safe unplugging of the battery. Remember to hold it for a several seconds (idk, how long, I hold it for 10 secs or so). After this you can safely disconnect your battery and be much safer with your motherboard. Remember, that laptop boots only when connected to powerbrick.

[@noway9880]

are you quite sure about this m8? the system is shutdown. even if not, pressing power a couple times (to discharge caps) with batt disconnected would do her.

Such a calm voice and soothing music. Like a Bob Ross episode.

[@NexusTechRepair]

Haha thanks

[@kalcijs146]

Hey, commenting on old video here, but anyway- 25min video and no change of thermal pads??? Thats just a bad decision to disassemble a laptop and leave thermal pads in such bad shape. In the future really consider changing them for every laptop that you disassemble, because they almost always get ineffective over time, and as you can see here- after disassemble they are broken, if you dont change them and just assemble laptop as it is, they will function even worse because for most of them there is not left much contact with chips and heatsinks.

[@daaood9996]

Thanks for this! I have a GS66 too and this will be very useful for me

It's unnecessary to remove the small screws on the fan unless you wanna clean the fan too. Unscrewed them, even tho i tried to be careful still ended up with one missing.

[@tfkrazvan]

Done this as well after undervolt. One issue i have. When im not doing anything on the laptop the CPU its staying at 52% and when im opening task manager the CPU drops instantly at 2%. Win 11 Any ideea why its doing like this ?

[@NexusTechRepair]

Must be something starting up with your system running in the back ground, I’d shoot for a fresh install and see if it resolved

What's the best thermal paste to use? Phobia Nanogrease Kingpin KPX Gelid GC Extreme

[@froof2330]

how often should you replace the thermal paste? i have my gs66 11uh for almost a year now and havent done it

[@maccentric]

When it's running hot, it's a good place to start. It really should last at least 3 years, but they may have done a sloppy job at the factory too.

[@gapspt]

Very nice video, only complain is that the video is mirrored :P

[@NexusTechRepair]

Yeah I’m sorry about that, I thought it would work out when I made the video, but I realized after the fact it’s confusing seeing it that way

[@StealthxAssassin117]

Do you know if there was any significant Temp improvement? before/after

[@NexusTechRepair]

I personally never saw any change in temperature before and after the repaste, other than possibly 1 or 2 degrees. My thought is that they pasted it really well from the factory because of how thin it is so I’m not sure it could get much better unless you used liquid metal, but I’d advise against that personally. It’s all about disabling or customizing turbo ratios for your cores that will decrease the heat.

[@ИгорьАлексеев-э6в]

​@@NexusTechRepairAlso liquid metal paste reacts with copper, because it contains gallium. So it sort of dries out and soaks into copper plate making it fragile. This causes huge thermal conductivity loss in future because of cracks appearing in the copper plate. So never use any liquid metal paste, unless you have chrome coating on copper parts of your heatsink.

[@DirtyReaper]

Excellent

[@merakliadam]

will this laptop go with normal thermal paste or liquid metal paste dude the place I bought it tells me I need to apply liquid metal paste to this laptop is it correct?

[@NexusTechRepair]

You can use either one. Just be very careful with liquid metal cause it’s conductive and can short out your cpu/gpu if it makes contact with anything other than the die

[@Matthew-no4dn]

Can you remember what change in temps you benefitted?

[@Vaelin223]

I followed this guide. No changes in temperatures after repasting. I used geled gc extreme thermal paste.

[@NexusTechRepair]

For best results on thermal performance, I recommend using my undervolting guide and disabling turbo boost, thermal paste only provides a margin of error of 2-3 degrees usually

[@Vaelin223]

@@NexusTechRepair Thank you for suggesting that. My laptop is already undervolted but I'll check out your guide.

[@danielcaballero872]

Greeting! This video was very helpful, thank you so much. I have a question, I accidentally took off the pink factory thermal glue. Can I just buy normal thermal glue or does it need a special type? Also I only bought 3g paying glue, my intuition tells me that it’s not enough to glue the hole laptop including the pink glue I took off. Again thank you for the video! I hope to hear from you soon!

[@NexusTechRepair]

There is a lot of different types of thermal paste, in a pinch any will do, but I’d personally recommend arctic silver or something similar as it has better conductivity for better heat transfer.

[@goorthiss]

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. For the power section (vrm) and vrams, I advise you to apply Upsiren UX Pro thermal putty. It is also a good idea to do undervolting.

[@andresd.rojasherrera6119]

​@@goorthissbest regard I want to understand well what you are saying, for the cpu and gpu of the msi gs66 I would use the ptm7950 pad, and to replace that pink putty, the Upsiren UX Pro? The problem with this last product is that I can't find it on Amazon, any suggestions? greetings!!

[@maximakristiniy2074]

why are you not changed paste at other components ? after you pull out and pull back their contact reduced ?

[@NexusTechRepair]

Thermals remain unchanged. Contact is still good as long as you don’t mess it up

[@NexusTechRepair]

That sounds like software/driver related issues, but if you’re at all uncomfortable trying to do this I wouldn’t until you do more research

[@9derick6]

Does it make a difference leaving the stock thermal compound on the vram and other modules? Should it be replaced? Thinking of repasting my GP66 leopard. Thanks for any advice.

[@NexusTechRepair]

It’s made zero difference as long as it’s not completely ruined after repeating the cpu. You could replace it if you want, but you’d probably need to order thermal pad replacements instead of using paste. You can always use a program called HWmonitor to see the thermals of your motherboard and all other components as well afterwards to confirm there’s no issue

[@DeepteshLovesTECH]

Holy crap! Those pink ones are not thermal paste! Those are the thermal pads that got melted!! You gotta replace them later.

[@NexusTechRepair]

They didn’t get melted, I’ve done a repaste twice now and they don’t stay perfect when you open it and put it back.

[@Dylan-yk5gg]

so ive had this same laptop for a couple of weeks now and it always ran pretty quietly unless i turned on performance mode in dragon center for when im gaming. I started up my laptop today and without even gaming my laptop is over 80 degrees celsius and the fans are running louder than normal, would you happen to know why?

[@Dylan-yk5gg]

nevermind, its seems to have calmed it self down and the temps died down as well, have you had that issue before though? is there any reason it might be doing that?

[@NexusTechRepair]

Sometimes the turbo boost will kick in even if you have it disabled and the gpu will ramp up, my thought is that it’s doing something in the background that doesn’t care about the settings you have set. But typically it does correct itself.

[@Dylan-yk5gg]

@@NexusTechRepair thanks for the response, thats my assumption too, after a little while it finally calmed down. I was freaking out thinking my cpu was about to fry lol

open up the computer like he did. For ssd, look close to the battery, you should have a slot empty facing the current one. Its nvme ssd only but you can put one in there. For the ram, look above the already filled ssd slot, under the black paper/plastic tabs, youll see the ram slots. they 2x8 by default, so get 2x16 to upgrade and make it worthwhile. good luck

[@corbinknight9702]

I hope you still monitor your channel comments(videos is 3yrs old). Do you by chance know what size thermal pads the other components use? I think my sons gs66 is having overheating issues. The screen freezes and has pixelated screen. This doesn't happen every time. It happens randomly but not all the time on the same game during the same scenarios. Why did you feel the need to replace the paste? Did you see any performance increases or temp improvements after replacing the paste on the GPU and CPU? What brand/size pads would you recommend?

[@NexusTechRepair]

I didn’t see any respectable changes in thermals from changing the thermal paste unfortunately. Though that’s not to say you won’t it depends on the length of time he’s has the laptop. I still stand by using throttle stop and disabling turbo boost as a great way to reduce heat with minimal impact on performance. However the issue you state he’s having sounds like a possible GPU starting to go bad, definitely something to keep an eye on. As for the thermal pads I didn’t replace them and it worked just fine, but some people replace them, if you want to you can find some on amazon or even get larger pads and cut them to the size you need

[@corbinknight9702]

@@NexusTechRepair ok. Thanks for your reply. I'm unsure what mm and brand to buy. Any suggestions? How many I would need also? Link me if possible and qty. Thx!

[@wisemay5895]

When you responded to the question about just removing the fans, did you mean that it is possible to say, replace a defective fan by simply removing the fan screws only, sliding the old fan out, then sliding the new fan in without having to remove the heat pipes too? That would be great but it sure doesn't look like you can. So can you?

[@alt666]

Used this to repaste mine again. Repasting was definitely the right idea cause i swapped my 2060's 80w vbios to the 115w vbios and for the first time my gpu hit 70c.

[@michaelj.caboose2034]

I’ve had a GS66 stealth for a few years and recently it has had some really bad issues with overheating. If I don’t have the fans going at around 8000 rpm while gaming my computer overheats at around 186 degrees Fahrenheit and shuts down within 10 to 20 minutes sometimes even quicker than that. I’m typing this on my phone but when I can get to my laptop I’ll post the specs as well.

[@Vaelin223]

it's been 3 weeks, where are the specs stop being lazy

[@tobywankenobi3088]

I know this is very late but do you know if this still works on the GS66 12UGS? One of my fans is broken and is gonna need to be replaced, but it doesn't look like you can only replace one fan. So if I have to replace the whole cooling system I'll have to repaste everything, even on the cooling solution itself probably.

[@NexusTechRepair]

I suspect it’s very similar if not exactly the same, it’s still a gs66, the suffix typically just indicates different specs or processors

[@NoahCuz]

Aaaaand I stripped a screw

[@NexusTechRepair]

Noah nooooo! Damn man I’m sorry to hear that. Sometimes if you use a flathead that fits snug in the screw and apply a decent amount of pressure while you turn slowly you can get stripped screws out.

[@goorthiss]

​@@deadline8416 It will fit because at 45°C it turns into a liquid paste, which will fill micro irregularities. Before cutting it out, I suggest putting it in the refrigerator for an hour to more conveniently remove the protective film, and you can use scissors to trim it. PTM has to pass through several phase changes. Over time, it will only dissipate heat more efficiently. With normal use of the laptop after ~3 days you already get its optimal performance. This can be accelerated by running a stress test through, for example CineBench for the CPU and MSI Kombustor for the dGPU.

[@okkogael]

Nice video my friend! I think I have an error with my GS66 (I bought the same spec) and I have always the third fan running at 0RPM...

[@jongalletley3897]

I had a similar problem and when I opened mine up to install ram/ssd, I discovered a bit of the black tape was stuck to the fan! I'd suggest checking the tape placement near your fans if you can. My fan also had to be "popped" back into place after removing the tape, so double check that it's seated correctly and spinning freely.

Which is the best video to watch mate for dummies out of yours? It's difficult to understand for someone who is new to this stuff. My stealth is quality, but the fans are mental, does undervolting impact performance much?

Undervolting doesn’t impact performance at all. Disabling turbo boost will solve the fan noise. The undervolt update video should help quite a bit.

Since you undervolted and limited boost frequencies, did you see anything concerning in the behaviour of the device. Also did the fan speeds decrease with the temperatures or does it remain very loud? Thanks
