We now have evidences that the BIOS adds arbitrary constants to the
measured voltages (150 mV for Vcore.) This explains the differences.
What we don't know is, why the BIOS does this. At any rate the driver
is correct and doesn't need to be fixed. You can add offsets in
sensors.conf to match the BIOS readings if you want.

Aha, maybe _you_ want to lower the fan limits ;) Adjust the values in
sensors.conf and run "sensors -s" to apply the changes.
