List y'specifcation more clearly... in fact create a sig when y'not in a hurry.
I'd use more than one program to check the temps as they'll probably give completely different readings. First check the BIOS, then use the one you mentioned... then try Motherboard Monitor
and what seems to be a Shuttle users favourite... SpeedFan.
These should give you some idea of what sort of range the sensors give out. Keep us in formed and welcome to the fold!
