My buddy replaced his thermal paste and thermal pads on his 3090 and claims it produces less heat now. I just can not figure it out. Everything I know about thermal dynamics tells me it should be producing approximately the same amount of heat (assuming it was not throttling) or more heat (assuming it was throttling).
He is reporting 30-40 degree lower temps which is telling me he is putting more heat into the radiator and he is reporting better 3D mark scores.
He claims the fans are running slower which makes sense as the temps are lower meaning more heat is getting to the radiator but the radiator needs to be hotter to transfer the same amount of heat to the air at a lower speed.
He claims the radiator used to burn to touch but now is only warm to touch. He also reports his room heats up less after the replacement.
I know resistance goes up with temp but the difference from 70 C to 100 C is less then 5% I thought.
I am thinking this is just his preconceived bias but I would love to hear your thoughts.
-edit
All temps were in C
His memory temps were 109 before and 72ish after
VRMs were 95ish and down to 65ish after
T junction was 112 and down to 95
GPU average temp was 92 and down to 84 but he has a hot spot that is up 2 degrees (he suspects bad thermal paste application)
Now the question is did I mark best answer because that is what I wanted to hear lol
