I am proving my A7N8X with three different bios versions and I don't find any variation of significant temperature in the internal diode.
The only variation that I detect is that the reading is erroneous when an Athlon XP is used with palomino core
and with 1003 the temperature of the system is erroneous as well as the temperature of the pwrtemp.
It is possible that the measurement is not
correct one but we do not have very much where to choose exempting
the costly systems of measurement.
I believe that it is a good motherboard to evaluate the performance of our waterblocks.
