Hey there I just bought a dfi nf4 infinity and an opteron 165... For some reason My cpu seems to overheat when i do a prime95. Stock CPU temps would go above 54 Deg. then freeze up. I realized it wont if I have the side of my case off, so I added another fan inside my case blowing fromt he front/middle but doesn't seem to help any. I'm still using Stock heatsink and removed thermalpad and put on Artic Silver (did this twice just to make sure I didn't use more or less). Bios is updated on my mobo. I know my PSU is only 20-pin but the computer seems to work fine with it (thermaltake 420w) and my case is pretty bad for airflow.. Please help.. this is getting annoyingggg. thanks
