The voltages look rather good to me, but you should compare with what
the BIOS says for confirmation. The limits are wrong but that's
expected - set them in /etc/sensors.conf and run "sensors -s" to write
them to the chip.

No fan speeds, strange, unless you have no fans on that systems, or
very very slow fans (in which case you should increase the fan_div
values to 16 or even 32.) Are there fan speeds displayed in the BIOS?

Temperatures look wrong, -48 typically means no sensor connected,
+108.5°C is too high to be realistic unless your computer case is on
fire ;) Try changing the thermal sensor types... although the BIOS
should have set them up right.

The lack of fan speeds and proper temperature readings might hint at an
additional sensor chip on your board. If you can't get them out of the
W83627THF, try running an up-to-date version of sensors-detect and see
if it finds an extra chip on the SMBus.
