Mi notebook Pro GPU reaching 98 degrees Celsius

Shouldn’t get up to those kinds of temperatures even under heavy load. Mine doesn’t, but then again I replace my thermal paste with some leftover Thermal Grizzly I had.

Replacing thermal paste will definitely help, though YMMV. While you’re at it you might want to check if the fans are working/spinning, clean out the dust bunnies in the air outlets/inlets and clean the fan blades as well. It could just be a simple case of dust bunnies obstructing the air inlets/outlets.

Good luck!

That’s not right. Should never get that hot, 100% load mine is 76 degrees C max. It’s either dust blocking the inside (Is it old?) or yes a repaste is needed.

Thank you both for your reply. I just ordered a Thermal Grizzly Kryonaut tube to replace the thermal paste this weekend. Now I notice that the fans are kicking in more often than before, even when its not under load. The first time the laptop got that hot under heavy load I operated it for several hours because I was using a Bluetooth keyboard and mouse, so I didn’t realize it was that hot. Is it possible that because of this the thermal paste that was applied from factory is not working properly anymore?

I will change it anyways so I hope this improves the temps. I bought it about 6 months ago and it wasn’t like this at the beginning.

Max temps on mine never get above 70-ish, even under heavy loads/gaming. Honestly, most of the factory-applied thermal paste is pretty rubbish and you’re better off applying your own thermal paste anyway. If I had to guess, I’d say it’s probably a combination of dust and crappy thermal paste. I bought mine early last Dec and when I did the re-paste a few months later the factory paste was already drying out.

This laptop has a pretty efficient cooling and any decent thermal paste, like MX-4, that’s properly applied should do just fine. I just happen to have some extra leftover Thermal Grizzly Kryonaut lying around from before. Btw, remember to clean out the dust bunnies that have taken residence in your laptop when doing the re-paste. You’ll be surprised just how much dust collects in a short span of time. Good luck!

Thank you very much for your responses. The thermal paste arrived yesterday and I tried opening the laptop without success. I was using Chris’ video as a guide but even after using several plastic picks to pry the cover open I could not do it (the picks ended up suffering a lot, see attached picture). I felt I was stressing the metal too much and that I was bending it. I admit that I’m not good at this kind of work, I always end up breaking delicate pieces. Any recommendation on how to do it properly? I will try again this Sunday.

Also I wanted to ask you guys, what’s your CPU temperature in idle?

Thanks.

Getting in for the 1st time is a pain. It gets easier for subsequent attempts. (That’s what she said… 😉 LOL!)

Start from the back where the hinge is. Remember to remove the 1 screw that’s hidden under the top centre rubber foot near the hinge. There are clips all around the edges of the bottom and if I remember correctly, 2 in the middle (just south of the air inlet). It does take some force to pop the clips out for the 1st time. Don’t worry, you won’t screw up the cover that easily, you’re more likely to break your picks and pry tools. Plastic will bend/break long before the metal cover does. Just follow the Chris’ video or any other disassembly video on youtube. Best advice is to have lots of spare picks (you can use the spares as wedges once you pop the clips) and to take your time if you’ve never attempted this before.

Depending on ambient temps it’s usually about 35-42 deg C doing nothing on idle, give or take a couple of deg C.

Thank you for your suggestion Kenneth, I managed to open the laptop, cleaned the processor, the GPU and the copper heatsink with 99% 2-propanol and applied the new thermal paste using the included plastic spatula. The results on load so far (one hour after closing the laptop again) are a massive decrease in temperature from 98 to 74 degrees C. I don’t know if there should be also a decrease in temperatures on idle, but I’ll have to test it for a few days to have solid results.

Thank you all for your help.

Max of about 74 deg C under load sounds about right. Idle temps should decrease as well. Seems like things are looking just fine, great to hear that you’ve gotten everything sorted out.
