This one confused me too.  It's not a temperature at all, its a range
indicator running between 0 and 255 with 100 representing the average
expected, numbers below 100 representing below average values and
numbers above representing above average values... so for example one of
my drives reads:

194 Temperature_Celsius     0x0022   118   112   000    Old_age     
-       40

--that number at the end is the actual temperature in celsius (40) --
which is way hotter than it should be, hence the 194 for the operational
value (way above average).  

All this and more can be derived from the smartd and smartctl man pages.

Also, be aware that FC comes with a pre-existing smartd conf file that
won't match your real system, and will place spurious errors about not
being able to read certain devices in your logfiles.
