MBP doesn't **** off = still within acceptable heat range?

Tcase for the Intel i7-2600 is 72.6C, so the desktop processors can run just fine up to hot temperatures.

The reason that the overclockers don't want to see 80C+ is:
1) They are operating way beyond the rated/tested specifications of the CPU
2) The lower the temp, the better overclock you're going to get, in most cases
and
3) It's pretty easy to cool a desktop CPU so why not do it

smaller die->lower power usage->temperatures are lower.

And NO. Desktop CPU IS NOT lower heat tolerance, that is a complete none-sense. It's more like the opposite.

Desktop CPU can go over 80c easily without crash, it usually crash around 100-105c, which is the exact the same as laptop.

Keep in high temp will only damage it...

If you read the intel specifications for the 2nd generation Core i7 Desktop processors, you'll notice they mentioned the T-Case temperature of ~72.6 deg C.

Now if you look at the laptop processor, you'll see the Tj Temperature is rated at 100 deg C.

According to Intel, the desktop CPUs have lower heat tolerance levels. I'm not saying it can't be pushed over the rated temperatures, but from Intel's standings, it's risky and could damage the CPU.

T-Case = Temperature of the Processor
T-Junction (Tj) = Temperature of the Processor Die (Aka, without IHS)

Processor temp is always 20c-30c lower than the core temp. There is no point to compare apple to orange.

Wheres your proof? The IHS sits on top of the die with thermal paste in between to create a good contact. The temperature would not be a 20 to 30 deg C difference. A difference of max of 10 deg C could be possible.

This is not the same as taking the temperature of the die then taking the temperature of the heatsink a few inches away. That gives a difference of about 20 deg C

I have a core i7 920 @ 4.2Ghz, I constantly running at its max.

The processor temp is generally around 60 when stress out, while the core temp is about 80c.

hell, I can go way up without crashing.

You are still comparing apple to orange, makes no sense.
