Laptop CPU and GPU overheating.

[MichaelKanRS]

My laptop (Gigabyte P34W-v4) has been overheating while I play games such as Overwatch. For example, my i7-5700HQ reached 95c and GTX 970M reached 87c. Right now, I am thinking of replacing the thermal paste on the chips. I need recommendation on what paste I should use. If possible, please recommend me other solutions as well.

for a laptop that's not over heating. While replacing the thermal paste may help, it may not. I have a similar setup myself and those numbers are about what I get depending on ambient temps. I would clean your laptop with some duster regardless as for good thermal paste there are several decent ones. I like arctic personally but i listed some reviews for you to check out.

That's much higher than I have ever seen on any of our lappies. I get a lot of lappies brought over with similar issues and the solution 95% of the time is to:

1. Take off rear panels.

2. Roll this into room

3. Attach the fine local nozzle which sends a very confined stream of air...

4. Remove whatever to get access to the inside face of the copper heat sink fins and blow out all the cat hair, dandruff, dust bunnies, cookie crumbs and whatever else is jammed between the fins..

5. Then placing a finger on each fan and holding tightly so they don't spin, blow all the dust off fan blades and out of shrouds.

6. Blow out all other nooks and crannies...removing Storage and memory so you just don't jam stuff underneath.

Never blow air into the heat sinks from the outside
Never let go of those fans when applying compressed air.

After that I retest using Furmark and RoG Real Bench... If replacing TIM be sure to use one that is NOT capacitive (AS5 is).

I use Shin Etsu G751 ... not only does it have the best performance (outside Grizzly Kryonaut and the liquid metal stuff), it's real cheap (<$4) because it comes directly from Industrial manufacturer (as opposed to being repackaged for PC industry under 3rd party name), it has no curing issues (AS5 takes 300 hours to cure) and it is not capacitive.

AS5 web site is down so I cant give ya the link but read the capacitance and curing warnings on AS5 home page

Worth reading:

80 way TIM face off ... it's old but no real new players at the table other than grizzly.

To JackNaylorPE...Yes your walkthrough is pretty much dead on for a good cleaning as usual. As for the temps I can't say what kind of laptops your referring too...mine is very thin (even thinner then the OPs) and my temps were a hair better just not much when brand new out of box (87-90C for CPU and 83-85C GPU). His laptop seemed fairly thin as well so I still don't find those temps out of this world hot but hopefully they can be improved upon with a good cleaning and if needed new thermal paste.
