There was some recent discussion about updating some of the drivers to
deal with hardware that reports values with 0.001 deg C resolution
rather than the more common 0.1 deg C resolution.  I am not sure but I
think some Intel boards were affected by this.  In other words, dividing
your reported temperatures by 100 may give you the actual values.

0 C (probably not connected)

17.80 C

18.60 C

19.40 C

If the machine is sitting in an air-conditioned data center, those
values don't seem out of line.

The latest version of sensors-detect is "5108 (2008-01-22 13:22:47
+0100)"; you may get better results from a newer version of the
complete lm-sensors package if possible.
