Hi Derek,

the temperature sensors in the AMD chips are known to be unreliable.
The measured temperature pretty much only means "much below the maximum
temperature". Temperature gets more accurate towards the limit. You could
try to figure out the real current temperature (guesswork ;-) and apply
a correction factor in /etc/sensors3.conf.

The w83627ehf dosn't seem to be connected to any voltages or temperatures.
This is actually odd since some of the voltages are internal and should always
be reported. I suspect the chip, or at least its hardware monitoring functions,
may be disabled.

You might want to load the 'i2c-piix4' driver to get the DRAM temperatures
reported as well as support for the w83795. Be careful with IPMI, though - 
if it is active it may access the chips in parallel, which may cause system
instabilities.

Thanks,
Guenter
