Something weird is happening that does not seem to be temperature.

The intel motherboards use a weird system of sensor reporting, that the
lmsensors people had not figured out at least as of a year ago. I am
familiar with linux, but I suspect freebsd is the same.
mbmon, healthd are apparently freebsd systems for perhaps getting the
