I don't know which i7 you have, but the intel datasheet for the i7-870 states that the maximum case temperature is 72.7C. The reported cpu temperatures will be a little higher at this case temperature, maybe a few degrees. How much higher I can't say without knowing the thermal resistance. The i7-870 motherboard I have with a large cooler idles at about 40C. Under heavy load it runs at about 65C. John Theus
