Measure heat sink thermal resistance?

[overclockoverheat]

If you heat up one CPU core with an intensive test, the heat should travel to the heat sink then back to heat up the other cores. If your heat sink is very well attached (low thermal resistance), the other cores would heat up more. If it is not well attached, the other cores would heat up less.

Is there an utility written specifically to use this to gauge how well CPU heat sink is attached? I keep thinking my heat sink may not be very well attached, but have no way to tell.

The integrated heat spreader on the CPU case is between the single CPU and the heatsink. It will do exactly what the name implies, spread the heat BEFORE it gets to the heatsink. This is where the practice of "delidding" a CPU and enhancing the conductivity between the silicon and the integrated heat spreader comes from.

Is your CPU hotter than others for the same model? If not, your heatsink is properly attached.
