Well with Real Temp promoting controversy by reporting different temps, dispelling the myth of Tjmax based on mobile cpus, and getting closer to the truth with the nonlinear calibration, I think Real Temp is partly responsible for getting intel to see the light on temps, at least providing 45nm tjmax's, confirming what you already discovered regarding idle temps, and most importantly suggesting a future fix. So, Unclewebb, definite Big !

Interestingly, all the 45nm Quads you can add 29-30C to Tcase and get Tjunction. All the 45nm Duos you can add 26-28C to Tcase and get Tjunction. I know one of your 65nm did not fit that mold, but wonder if that was an intel mistake or intel farting around with one model. The higher the power the greater the gradient, which makes sense.
