Poor you ;)
You might enjoy "sensors -f" then.

I'm not sure you want to do that, actually 33 + 40 leads to 73 degrees
C which is quite high for a Nehemiah. Don't go frying your CPU just to
demonstrate that your BIOS has a bug ;)

Yes, the value gets chopped at 0 by the F71805F.

OK, so the CPU temp is unreasonably low just as it is under Linux.

Cannot be a duplicate reading, physically it wouldn't make sense. It
really has to be a 3rd sensor. Either the BIOS is averaging temp2 and
temp3 into "System Temp", or they indeed just ignore temp3. Given that
temp2 appear to have the same value anyway, no big deal.

You're welcome. I'm happy to see my driver is widely used :)
