i just started playing ArmA II: Reinforcements and after about 15-20 minutes, my computer would shut off immediately. i figured it was some sort of heat issue so on restart, i went into the hardware monitor. it showed my CPU was coming down from 98*C (assuming it hit 100* and that's what triggered it to shut off). i'm not overclocking at all. i read that this cpu should be running between 55*C-62*C. at idle right now, it's running around 68*C-70*C, which is still too hot. i'm using the stock fan and heatsink that came with the cpu and i made sure that it is operating (100%, ~3500rpm). i'm pretty sure it's not an issue with my case because my 5970 isn't overheating at all. is the stock fan and heatsink just crap or what else could be going on here?
