You can always apply arbitrary offsets via compute statements in sensors.conf, but 1* you'll have to guess the offset and 2* there is no guarantee that a simple offset will do the trick.

(temp1/2 are 34 now) In general you can hope that the sensor types set by the BIOS are correct. -- Jean Delvare
