I've got an Asus P4C800-E Deluxe board, and it has a utility that shows what the temp is, and has provision for an adjustable threshold above which it will provide an overheating warning. Also shows processor temp with the same settable threshold warning. It's a 2.8 P4 Northwoods. Trouble is, I don't know what those threshold temps should be? I have added extra cooling fans and vents to the upright case. Thanks!
