Not easily.  If coretemp(4) is loaded, you should have some sysctls
named dev.cpu.X.temperature which contain the temperature of the core in
Celcius.  Otherwise, you can try utilities like mbmon and healthd, but
those were written for old (circa 90s) hardware.

Also, are you running powerd(8) on this machine?

That's a good start; your memory is probably not the issue then.

Wattage is not the only thing that matters with a PSU.  Voltages are
significantly more important, if you ask me.  I'd make a list of what
your voltages are (go into the BIOS and see) and provide them here.
There may be one which is significantly off, indicating a bad PSU.

Windows offers many free utilities that do this; I'm not sure about
