What kind of temps are getting mythy? I got the same board but I think its temp readout is all messed up. Mine idles at 60c and loads at 70c no matter what the cooling, weather, in case or out. I'm running the latest beta bios 0603 tho it was the same with the older ones too.
Great OC btw, I have to feed my B3 1.4v for a little over 3.2GHz
