The issue of Thermal Specs and Max safe operating temps/voltages

I have been reading through the forums and have noticed, especially with the Core 2 Duo crew, that there are a few of questions that keep coming up.

First: What is the unclocked idle temps that I can expect from my processor?

Second: What is the expected load temp of my unclocked processor?

Third: What is the SAFE idle temps on my overclocked processor and on the same thread, at what point should I be getting concerned with the load temps of my overclocked processor?

A secondary but still important question is what is the safe voltage or Vcore for my processor and at what point am I likely to fry it?

After a very cursory search, I came across Intels glossary of terms for their processor specifications which served to muddy the waters a little. This is a couple of quotes from it.

INTEL said:
The thermal specification shown is the maximum case temperature at the maximum Thermal Design Power (TDP) value for that processor. It is measured at the geometric center on the topside of the processor integrated heat spreader. For processors without integrated heat spreaders such as mobile processors, the thermal specification is referred to as the junction temperature (Tj). The maximum junction temperature is defined by an activation of the processor Intel® Thermal Monitor. The Intel Thermal Monitor’s automatic mode is used to indicate that the maximum TJ has been reached.

INTEL said:
Thermal Design Power (Also referred to as Thermal Guideline) The maximum amount of heat which a thermal solution must be able to dissipate from the processor so that the processor will operate under normal operating conditions.

This is all well and good, but the actual numbers that they publish are of course the indicated Intel safe and warranty covered operating temps and voltage, not the maximum that the processors could potentially operate with.

As we all know, not all processor are born the same not even the ones that are named the same and have come from the same production line. So what is safe, what can we potentially expect as an OC from out chip and what sort of temps can we expect?

Has anyone here actually come across some data to use a some sort of a guideline that could potentially be created as an OCuK sticky for OC guidelines? There is a fair amount of data within these forum pages, has anyone given any thought to bringing as much of it as possible into a central DB?

The idea was for a breakdown like:

CPU: (include things like Core stepping etc)
MoBo:
Cooler:
Stock Clock:
Stock Vcore:
Stock Idle temp:
Stock Load temp:
OC Clock: (Incl multiplier etc)
OC Vcore:
OC Idle temp:
OC Load temp:

Once the info was gathered getting it into a central DB I think would be a brilliant guide to first time overclockers especially with providing some sort of an early warning as to when something is not quite right rather than jumping online, starting a new thread and asking "are my temps ok?" or "I have my Vcore at 1.55, is that safe" meanwhile their nice new processor is slowly cooking itself into oblivion.

Anyhow, just an idea - if there is interest in this how would we go about getting this compiled?
