[Resolved] Changed thermal paste of laptop but CPU temps keep "jumping" up to 96°C

September 16th, 2020, 3:30 pm

So I changed the thermal paste of my laptop last week. The GPU temps went down but the CPU temps keep "jumping" up to 96°C especially when gaming. I also noticed that my FPS got lower than usual in League of Legends (since it relies mostly on the CPU). I followed a Youtube tutorial of the exact same laptop model repasting and I am pretty sure I got everything right. I'm suspecting there's not enough pressure applied from the heatsink on the CPU? Did anyone encounter something similar? Any suggestions/tips on what I should do? I thought about reapplying thermal paste on the CPU but I wanted to get some feedback before I do something that won't have any effect whatsoever.

Thanks in advance.

I've checked if the fans were working before closing the lid and they were fine. For now I increased the fans' speed to maximum until I figure this out.

I have it at High Performance all the time if that's what you mean. I can't find Gaming Boost.

(Resolved)

After reopening the case and heatsink, I noticed that I forgot to apply paste on the small parts circled in the photo with red. After doing that, CPU temps went down by 10°C. I guess 80-90°C CPU temp is fine when gaming. When I'm not gaming it's at 65-75°C.

Thank you all for your help!
