Well, given that all of the other temperatures, such as the motherboard,
are reporting values in the 25-30 range, and the software is tossing a C
after them automatically, I am leaning to trusting the software, and
presuming that the temperature is in the core of the cpu, which to me
doesn't sound unreasonable when you consider the vast quantity of traces
of current snaking all over the multiple layers of the chip in each and
every second.

The problem comes not from the specific core temperature if it is in an
acceptable range for the processor design, but in temperature changes -
uncontrolled escalations or sudden and significant cooling.
