I did some research on the web. Looks like temp3 almost always shows
very low temperatures for the W83667, and also for w83627ehf. Also, since
the reading is low, but there is no low limit, there isn't really a reason
for raising an alarm. 

Also, min/max values for voltages seem to be off almost everywhere.
And values for temp1_max and temp1_hyst are often negative or very low.

So, in summry, looks like -B support is just as good or as bad as support
for the other chips. Not sure if that is good or bad, though, since the 
off-track readings are so common.
