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
