You can just change these values to something more suitable. Edit
/etc/sensors.conf, seek to the w83627thf-* section, edit the "set
in0_min" and "set in0_max" lines.

Does the BIOS report any speed for that fan? If so, what is the value?

The temperature values are admittedly strange. What temperature values
does the BIOS report, if any?

Either your W83627THF chip needs some additional configuration (such as a
different thermal sensor type selection), or you have another chip on
the board handling fans and tempeartures.

Please provide the full output of sensors-detect. Also, let us know which
version of lm_sensors you are using (sensors -v).

Note that you may want to follow-up on this on the lm-sensors list [1]
rather than the LKML, which isn't really the place for user-space
configuration issues.
