I cleaned out all the fans, but they weren't that dirty. I can't test
the temps while the system is under load (have to reboot and check them
in the bios). My Dad said he'd bring by his spot-read thermometer if he
remembers so I can check the temps of everything. The CPU heatsink and
memory are cool to the touch under load. I didn't see any obvious signs
of burnt/damaged components. No telltale smell either.
Thanks,
Micah
