First of all, thanks Wisecracker for the bump
I downloaded Everest, and at first it seemed to agree with my mobo, however the temperature never updated and stayed at 27, even after playing a game or stressing with Prime95.
I've done some research and it seems that some Brisbane cores have messed up temp sensors, which would entirely explain my problem. Unfortunately, I don't know what range for me is safe. I cranked up the multiplier to x15 (3.0Ghz) and have no problem playing Assassin's Creed @ full max settings (SpeedFan says it's about 20 degrees above idle, which should translate to 50 or so). I'm afraid to stress it for too long with Prime95, but under any normal usage I should be ok.
Oh well, thanks for the help guys.
