I recently had someone install a PSU and GPU for me, for gaming on Steam. The gpu was a Sapphire Radeon HD 6850, PSU Antec 600W, my CPU is a Core Duo E7400 @ 2.8Ghz. I played some games on it worked fine, but then I started up a game with somewhat high requirments (Strangers Wrath PC port) and it shutdown, probably because of overheating. Here's what speed fan says at idle..
I realized one was incredibly high, but I don't know what this means.
Also, the port that I was playing was complete crap, so it could have been a memory leak or somthing, but I doubt it.
Any help is appreciated, I'm a bit dumb-founded...
