ah here we go:
as some of you know the temp reading you get for your cpu mighht be by 20C off (higher). i bet some of you didnt know that!

i had an msi board and the highest temp i had was 42C which i thought was obviously my cpu temp. the sensor used was a winbond sensor!
i got an Abit Kt7 max2 board now and the highest temp i get is 58C! the sensor in use is a LM90 sensor. i still have a winbond sensor showing up my 42C!
funny thing though is that there are two temps for the lm90 sensor and the winbond sensor! lm90 is 58C and 43C and the winbond is 50C and 43C!
i am very very confused now!
where do the sensor get their temps from! i take it the lm90 sensor reads the actual diodes in the cpu core and somewhere else on the cpu. or am i wrong?

somebody please explain the temp sensors to me and how it works ;)

PS all hardware is the same just different mobos
