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.
