What DuckieHo and I are thinking (if I may presume as much) is that it's far more useful to think in terms of temperature deltas, specifically from idle processor conditions to maximum load.
Naw... processor idle condition and temps varies. Go from ambient air temperature to maximum load. Unless you are using active cooling like TEC or evaporation, just above ambient air temp is the lowest possible since this is where all the heat is going. Many users already provide their maximum load temps with ambient temps.

So, this essentially means that there is a direct correlation between ambient temperatures and maximum temperatures, yes? The temperature delta between these readings would remain constant.

But wouldn't this also mean that the idle temperatures would also have the same relationship between ambient (and therefore max load) temperature? Mind you, I don't consider idle temperatures to be all that important; max load temps are where the rubber meets the road, so to speak.

Too many questions, too little data!

(And thanks for indulging my curiosity and sharing your thoughts.)

When you say "idle"... what does that really mean? Are any background tasks running? Is Vista or Windows 95 running? Are all the cores idle doing nothing? These would make comparing idle temps too difficult. When at load, we can surely say that the all processors are working within 1-2% of their maximum. Hence, we can compare the maximums. Idle however is not the minimum and has too many variables associate with it. While you can compare, load is much more straightforward and standardized.

Excellent point, sir!

This is also why I've said to others that idle temperature readings are irrelevant, and that max load temperatures are far more indicative of cooler performance.
