yes we all know TAT is the right one, and TAT tells you the temp of the DIE it self, everytime this question gets asked, everyone says 'use the TAT temps' and never answers the damn question. i tried twice and gave up. my TAT readings are WAY higher than the BIOS or Speedfan, or any of those. But everyone knows that, TAT's the only one that takes actual Die temps.
the question was though: WHAT IS THE LIMIT ON TAT!?!?! can we go to 65 or so on TAT because that's the DIE temp? and not the IHS temp? or do we stay under 60 with TAT, in which case these chips are not as cool as they claim.
The Thermal spec of the CPU is approximately 60C on the center of the IHS (the Case Temp). This is according to the Intel website (please, please don't make me look it up again.. it's a nightmare to find it... it's some 140+ page PDF file...)
However, this is at stock speeds, and stock voltages.
With a decent chip, it should be easy to stay under 60C when you have good cooling (if not, you either don't have good airflow/cooling, or you're overvolting like crazy). I use TAT for my temperature measurements, but I use Orthos to put a load on my cores. Whatever load TAT puts on the CPU, it's insane and temps shoot up to no end.
Also, I have yet to see real evidence that with the SAME test tools (Orthos, prime95), there is more than just a few degrees difference between TAT and other tools (make sure you have the newest version of Speedfan obviously).
My advice: Stay below 60C when using TAT. Even if this in reality is a case temp of like 55C, it's still a good idea to stay that low if you value longevity of your chip.
Granted, this is not a real answer either, but it's hard to find the *real* answer, since Intel is not going to bring out specs that include overclocking.
Finally, those chips do run fairly cool (at stock!), but hey, any CPU you overclock that much (1GB easily), with some overvolting, will get sweaty. It's not that they run hot, it's that they just overclock like mad!

Thank you VERY much Chozart, if you hadn't recently been stripped of your rep button, i'd click it furiously. once. lol
Cheers!
