So I've some problems with my computer overheating. I first noticed the issue a few months ago when trying to play a fairly high end game, but it's somewhat possible that this has been an issue from the beginning and I never noticed because I didn't try to run anything particularly extreme. Reducing the FPS on the game largely fixed that issue but last week I got some more high end games (Crysis and Metro 2033).
Trying to run these games now immediately causes issues and using Everest Ultimate Edition Trial I found that my individual cores (CPU#1, CPU#2, CPU#3, CPU#4) got up to around 90C, although the CPU (the one without a number next to it) still said around 40C (No clue what that means). After shutting down a game the temperatures dropped significantly, getting to around -20C, although my motherboard hovered at 90C. After not playing for a while the individual cores are around 50C, CPU is at 30C, and the motherboard is around 35C.
looks like they use the stock intel cooler, it may need to be re-seated. check the pins are all snapped down properly and the fan (including case fans) work fine. if they do, then just re-seat the heatsink. you will need to clean off the old thermal paste and place new paste down.
I've been pretty good about cleaning the dust in the case and on the case fans, but not the CPU fans. The CPU looks pretty dirty. Do I have to worry about replacing the thermal paste even if I'm only cleaning the fan? Will the old stuff already there be alright?
