I just built a system using a i7-930 and had over temperature errors right from the start. Doing some internet research on the subject brought me here. I tracked my problem to a stock cooler with a damaged foot. I replaced the stock cooler with a Corsair A70 cooler. I was wondering what normal or safe temperature readings should look like. I have been running the Prime95 blend test and monitoring with Real Temp for approximately 30 minutes and my core temps are 68, 64, 65, 63. Under Idle conditions temps are 46, 44, 46, 43.
