I could try it, I'll see...

But, I still can't understand your questionning. It is well established, since the Core2 begining (quiet 2 years now) that there's no good correlation between CPU temp and Core temp. So, it is normal you won't find any correlation in your analysis. The reasons are many, like I explained above (sensor technology, position, Internal Heatsink...)

Also, all trials to understand how those coretemp sensors work ended to a fail. In fact, Intel never published the full spec datasheets on those DTS sensors. All programs run on a guess and try based on many CPU samples and comparisions between ambiant and coretemp on idle, low volt and under clocked CPUs.
The thermal throttle point was prooved to be more correlated to core temp than CPU temp.

So, yes, don't expect to find a correlation between those values, that's really well known. That's all I'm trying to explain.

Now, the 45nm DTS sensors being different than on 65nm, is something I never read about. It is too early to state it as most 45nm CPUs, especially quadcores aren't out yet.

I will see if I can do the stats you ask for, as, in any case, I don't expect to see any correlation
