PH317-55-71YX Uneven Core Temps

sean6541sean6541 Member Posts: 3 New User
I recently got an Predator Helios 300 (PH317-55-71YX). According to HWInfo, while running Cinebench the cpu heats up to 92C and stabilizes at about 65W. Seems normal for a gaming laptop. What doesn't seem normal are the individual core temps. They vary by up to 25-30C, with half the cores at 65-75C and the other half at 87-92C. I've repasted the CPU multiple times with Kryonaut and Phobya Nanogrease Extreme, but no matter how I apply it (spread, blob) the temps do not improve. I noticed that the CPU die is very slightly concave, just enough to slightly distort the reflection on its surface, but is otherwise undetectable. I'm beginning to think that these temps are normal for the i7-11800H. Am I going insane? Could someone confirm whether these temps seem normal?

    sean6541 its completely normal for all cores having different temps now the issue is at 92 youre thermal throttling i suggest you to optimise your windows properly undervolt with TS and if needed repaste it properly with kryonaut or similar (i recommend the spread method only a thin layer covering both diodes its enough too much its bad same as too less) if youre able to without voiding your warranty otherwise send it back to acer to get it repasted with the stock paste which its not good anyways  and the cpu shouldnt go above 85'ish and dgpu 70/75 max also the main issue its the silicone lottery u might get a good one or a bad one good luck :)

    Here is is screenshot of HWMonitor taken about 10s into a Cinebench run.

    I've already repasted it a few times and am unable to improve the temps. It normally stays around 80C when gaming, 92C is only when running a benchmark (Cinebench). Oh well, silicon lottery at its best.

    sean6541 if youre at 80 on gaming its really fine nothing to worry about it at all just enjoy some good gaming  :)
