90 is very incorrect, 95 is the right Tj

So, I wanna know the CORRECT TjMAX for:
65nm QX6700 (B3 stepping)
Is it 90C? 95C? or 100C?
Damn intel....
wow, i'm confused about why it's so hard for intel to just tell their customers the right tjmax. incomprehensible.
Actually they did. They made the IDF presentations because of endless customer enquiries about temps. It doesn't mean they had to tell us everything. It doesn't mean that what they told us is true either. We just have to accept it, ignore it or "fight" for the real stuff.
I dunno if they were "mistaken" about the 65nm TJmax then who's to say they are right about 45nm TJmax, because they are supposed to put out far less heat but even with 95 TJmax they put out just the same, and if a 65nm is 95-90 then wouldnt a 45nm be less? this just make me wonder.
Really, if your 45nm is pulling the same heat as a 65nm on same volts or clock, then either you have a bad cpu, bad step, bad sensors or bad cooling.
If you want to compare how hot they are running, you need to know that Tj Max for both is correct or is wrong by the same amount. Then you need to assume the same slope error, which you can't really :p: A "better" idea is to drill into the IHS like rge did and measure the temperature of the top of the die yourself.
I think they are shady about the TJ max due to overclocking a lower priced cpu vs purchasing a higher clocked stocked cpu (though niche crowd) and losing profit.
I don't see how that would affect what they're telling us. A EE chip isn't going to run significantly cooler than a mainstream chip. Intel knows that few people are going to pay for an EE chip, that will never change. The funny thing is that the QX9650 and QX9770 actually have a 5-15C lower Tj Max than the mainstream chips, at least according to Intel.
The QX9770 and QX9775...at bottom of intel specs sheet "These processors ship without a fan heatsink. They require a third party liquid cooling solution." So definitely different cooling.
From IDF and from formula, Tjmax is dependent on power and cooling solution (also on ambient temps but they are same in intel testing). Q9650 is 95 watts and air cooled, QX9770 is 135W and water cooled.
I wanna know the correct TjMAX for: e6850 65nm
I know this is a bit of thread necromancy, but I've recently been shown this Tom's Hardware news article, which is stating all the TJ Max numbers for every Core2 (and Core2 based Xeon).
I want it to be right, I really do, but it's Tom's, and doesn't agree with everything else that's been posted here...

God damn you Intel, why can't you just publish the proper numbers already :(
Eller
I have my doubts they'll ever publish it.
so.. whats the tj max for an i7?
