It simply adds 22 to temp2 and temp3 before it displays them. I guess this is to compensate for a different thermal diode model. So all you need to do is: compute temp2 @+22, @-22 compute temp3 @+22, @-22 And you should optain the same results as in the BIOS setup screen. The fact that you were finding different formulas isn't really surprising. Since CPU activity is very different between BIOS and Linux, temperatures have no reason to be similar. I'll update and close the ticket. -- Jean Delvare http://khali.linux-fr.org/
