Possibly, I have not tested Speedfan or Everest, and certainly no way for me to test any of the other manufacturer's programs on my ASUS board, but my readings from PC Probe and TAT are within the margin of error to be the same and indeed, many times do match exactly.

There also is little chance of a 25c difference in temperature from the center of the IHS to the cores on the inside. I had similar thoughts that there may be some varience, although my thoughts were closer to 10c or less varience. However, in another thread The Manual provided some insight and information that I found to be logical and supportable that confirms that there is no way an 85c max temp rating for these CPUs can be maintained....especially when overclocking them.

Which is why I urge caution. I may be wrong, or The Manual may be wrong, or anyone else may be wrong. The only difference is, if I am wrong, the blackened shell of a $500 CPU can not be laid on my shoulders. I only give advise that I would feel comfortable doing with my own equipment, and that can be supported.

I wonder what the point is where those guys throttle.

sdumper probably knows...given his insane experiments on stock air (he had a E6700 at 71C IDLE!)

What I saw, the 85C is mentioned because Core Temp also works with other CPUs (merom), that have a much higher temperature tolerance.

Finally, what would be the difference between the design for the E6xxx series and the T5xxx/T7xxx (Core 2 Duo for mobile platform). The latter have a thermal spec of 100C(!)
http://processorfinder.intel.com/Lis...Spec=&OrdCode= (check the CPUs; all have a thermal spec of 100C)

As far I know, the design is fairly similar. Does that mean the desktop CPUs are overly conservatively spec'ed?

Enough stuff to speculate on... still trying to find a definate number from a reliable website (plenty of arguments in forums.. LOL)

At this moment, I am leaning toward the opinion that the E6xxx CPUs can take a good deal of heat, but I will not recommend (I have hinted in the past, for which I apologize) tems above 60C before anyone finds definate proof.

Very nice info, I learned alot from all of this, thanks alot Also can someone link where to download orthos? (its like prime 95 but does both cores)

I know the mobile chips use the same basic architecture........but they must be manufactured differently as I doubt Intel would state different specifications if they were identical. Mobile CPUs are expected to take higher temps, and they generally cost much more than their similar desktop cousins.

That's my speculations. I have also had little luck in finding anything solid, only discussions on other forums stating the same things.

Yeah...

I think sdumper is the only one who's gotten his Core 2 Duo to throttle, which seems indeed to happen in the 80C range. Since we always have preached to stay about 20 C or so below the throttling point (That's what the advised max temperature turned out to be, give or take), I am for now sticking with the 60C point as my limit.

If you're a bit more conservative, 55C might be a good advice.

60c Prime 95 load, or 60c TAT load.

I load the same in Speedfan with TAT and Prime 95, but when TAT loads it, it usually reports around 60c, whereas Prime 95 load reports 53c in TAT.

And to be honest, I strongly think that the thermal specification was taken from temps reported from the IHS, which would be similar to the temps that Speedfan reports rather than TAT.

Imagine if prescotts had a TAT, people would be freakin out from insane CPU temps.

I also get two separate load temps in Prime95 and TAT.
TAT is usually up by like 5-6C from Dual Prime95 load, which makes me think that Dual Prime95 is not fully stressing a C2D.

I agree 100% with your 2nd and 3rd statements, exactly what I was thinking .

That is assuming a lot of things, mostly that the core is that much hotter than the IHS, which is what we are trying to verify.

Also, if the specs are given for the IHS (and they are, this is confirmed by Intel's site), and supposedly the 3rd party software reads from the board, under the CPU......then what are we to conclude from the fact that TAT and the other programs read very similarly most times?

You know what? I am going to do a little experiment this week, I don't know why I didn't think of this before.

I am going to place a thermal probe between my IHS and heatsink and then compare the temps it reports to the temps reported by TAT and PC Probe, and Speedfan.

This way we can "see" what the temp of the Core is compared to the temp of the IHS where the spec is given from.

I should be able to complete this by Monday or Tuesday as I have several projects going right now.

Me too. Looking forward to it Speedfan, TAT and Everest are driving me crazy..
