This may be useful information, or it may not. I have an Asus
A8N-VM/CSM with an AMD64 X2 processor, not an Athlon FX. I get three
temperature readings, like you. I am sure that I have a w83627ehf, so
if it ends up you don't have the chip, this may be irrelevant.
However, I get one reading from the thermistor inside the w83627ehf,
so that could be your sys temp. (Put something cold on the chip, temp
drops rapidly.) The other two, for me, are both the AMD64 X2 chip. I
guess there's one per core? The two stay very close to each other for
me, so if you run your system at 100% utilization for a while, they
should both climb together. That's one thing you can test.
