Hee, hee, hee.. that sounds like a real undertaking to me :-) I guess
with the hardware monitoring and protection the board itself provides
(throttling cpu speeds) and such, I really shouldn't worry too much
about temps. The reason I sent the Tyan board back was due to some
overvoltage problems of cpu core voltage, and didn't want to wipe out a
pair of Xeon cpu's. That is one area I really would like to monitor, but
seeing what it shows now of 4.08 volts does not leave me much faith in
things. Its just too much of a job to try to swag all the components on
the mobo, as chip caps and resistors don't lend themselves to scrutiny
by old eyes, even with a magnifier! Perhaps one day someone will get
things figured out, but until then, I can take the readings with a grain
of salt and watch for drastic changes from the initial.. that would be
more useful probably in the long run
Thanks MaZe
