Right, so my PC runs pretty stable (55 celsius on load) but while I play GunZ, a game made 6 years ago, my Radeon 4850 overheats while I'm in the LOBBY, which apparently uses 50% GPU power.
IDK if the game is poorly coded or what, but I didn't have these overheating issues in my old case. I then left the Radeon 4850 lying around on my floor for a couple days before I assembled my new system.
I have cleaned out the 4850's fan with a cotton swab, and that lowered the temperature by like 10 celsius. However, when i'm in the lobby I hit 100% celsius. When I alt + tab, I see my temperature dropping to 64 celsius in a matter of 30 seconds
Happens in all games. To me, it sounds like the heatsink thermal paste has worn out. I mean, if it's 62 degrees celsius on idle, that means the air inside is cool. I've got 7 fans inside, and the processor never goes past 55 celsius on load.
Sounds like a heatsink issue, right? The moment the GPU starts doing work, it overheats.
