I was staring at my new epox 8KHA+ board yesterday (probably far too long I'll admit) and confirmed what I had read that the temp probe that sits in the center of the cpu mount is recessed below the level that installed cpu sits at and thus does not directly touch. I believe the this seperation that varies between models of MB's accounts for the big variation ppl report of their cpu temps. Why wouldn't a dab of thermal grease atop the probe allowing a thermal connection w/ the back of the cpu give more representative readings of the cpu temp rather than the circulating air ?
