It might be worth doing this:

sysctl -a | grep temp
dev.cpu.0.temperature: 42.0C
dev.cpu.1.temperature: 42.0C
dev.cpu.2.temperature: 42.0C
dev.cpu.3.temperature: 42.0C
dev.cpu.4.temperature: 42.0C
dev.cpu.5.temperature: 42.0C
dev.amdtemp.0.%desc: AMD CPU On-Die Thermal Sensors
dev.amdtemp.0.%driver: amdtemp
dev.amdtemp.0.%parent: hostb4
dev.amdtemp.0.sensor0.core0: 42.0C

...just to see what else might show up in relation to temperatures
in the various sysctl variables.

both healthd and xmbmon in their default states report a CPU temp of ~143c on my system.
42c is ~107F so that's not the problem.
