Legion 5 15ARH05H

Describe the issue:
As per title, I recently changed my thermal paste bc I thought the CPU temps were too big (up to 100 under load, floating around 90 usually, little did I know it was fine) and now im getting some crazy dumb temps, like 85-96 spikes just browsing the internet, under load it easily goes to even like 110 before limiting itself to 100. Gpu went from 66 to 80. Whats more, I noticed that on high load, my fans keep blowing out cold air, and iirc it used to be at least somewhat warm when playing games?

What have you tried already?:
Well the problem began after one of my thermal paste swaps. Since then I tried replacing the paste a few times again but to no result. I was using grizzly aeronaut (missclicked buying kryonaut lol). I dont put too much paste to make it look like a smore (this time I might have put too little bc I was running low), take a full minute/2 to try and evenly spread it on the units, and while the main gpu/cpu processors I always clean 100%, ngl that there are small bits of leftover paste between the tiny ones around the main units (I tried cleaning them as much as I could). Never changed thermal pads but they look good imo. Obv fans arent dusty. I inspected the heatsink and dont see it being bent anywhere or have any damage whatsoever. I always try to be very delicate with it, never fucking up the weight balance, but Im really out of options as to what might be going on here and I start to think I might mess something up, and its not conducting heat properly NoHope
In case the paste needed more time to settle down I tried waiting a day before doing anything intensive and still.
Ill be giving it on warranty either way bc my lcd is borked too. so I suppose I could tell them to check out the cooling system too and maybe get it replaced. Still, I'm curious if anyone maybe has any clues or has had a similar problem.

When did it start producing the issue:
Idk like a week ago, I think I noticed it on friday, but at least then i was able to play games without severe fps drops when the temps got to the mentioned 110 lol

Did you install new drivers or software?:
I didnt install anything new, especially nothing that could stealthy mine bitcoin 💀

Can you provide images/videos to show us the issue:
Lmk if you need any

Hmm next time at least please consult about your thermal paste choice.

#

We only recommend PTM 7950 or Gelid GC extreme as substitude

#

other paste has proven to be unsuitable for the legion.

my man repasted with one of the worst thermal paste for laptop ever

#

still that paste allowed me to keep it around 90s and not constant 100s so it was working good, leading me to suspect it wasnt the biggest offender here. Ill try gelid next time

#

how did you screw the heatsink in by the way ?

timid axle
#

I go by the numbers, and in reverse order when crewing it back on

stoic robin
#

mmm doesn't seems enough
