Bill, Have you checked the fan that cools the heat sink. I ran my QS with the side door open and discovered the heat sink cooling fan was bad. I ordered a new fan and while waiting for it ran the computer with a small electric fan directed at the heat sink cooling fins. New fan cost about $15.00. FWIW
