Motherboard Monitor versus Asus Probe

[HPLeft]

I'm finding that Motherboard Monitor and Fan Speed software give different
CPU temperatures than Asus Probe on an Asus A7V8X-X board. Basically, the
Motherboard Monitor and Fan temps are considerable lower than Asus Probe -
about 5 degrees F. The motherboard temperatures are identical in all three
pieces of software.

I've used the config wizard for Motherboard Monitor, and the preset config
for the Asus board. My guess is that Asus Probe is using a different
setting of some sort.

Any opinions on whether the Motherboard Monitor and Fan Speed CPU
temperature readings are more commonly used than those from Asus Probe?

Thanks in advance,

5 degF (<3C) isn't a big deal at all. The main thing is you have the
temperature in a reasonable range and then overtime ensure it remains in
that range. If it rises above what you have considered a reference condition
then it may indicate a poor fan (rotation should show up as lower too) or
excessive dust or poor heatsink bonding on the CPU etc.

IIRC the CPU temperature is measured by a sensor and an offset is applied to
better match it to the actual CPU temp. Where that offset is applied and
whether it is the same for both programs, I don't know. The Intel CPUs have
an internal temperature sensing diode on the chip.

Asus Probe reads the socket temp from the board mounted sensor beneath the
cpu and mbm5 reads the same sensor as well as the onboard diode built into
the Athlon cpus. 5 degrees in difference between the 2 programs is nothing
to worry about. If your fan speeds are varying in the 2 programs though,
more than likely you need to adjust the fan divisor in mbm5 settings.
