I really think its impossible to get accurate temps with this board. When it arrives it comes with the Probe utility being way off, saying 15C for cpu temp. According to the web page a bios update and an updated probe fix that. But now my temps seem too high. With good case cooling, 800eb 155fsb, 1.7v, and an alpha pep66 w/ artic silver my idle temp is around 40C and 50+C with load. When I use Sandra my temps are 10C lower which seem much more practicle. My motherboard temps always seem on target though.
