If CoreTemp sees 100º Tj on e6400, are it's temps wrong?

The Facts: C2D e6400 on a Gigabyte DS3

CoreTemp .94 reads Tj 85º and temps agree with my BIOS, SpeedFan, and EasyTune. TAT reads 10º - 15º higher

CoreTemp .95 reads Tj 100º and agrees with TAT. BIOS, Speedfan, and EasyTune read 10º - 15º lower.

So which is right? I'm pretty sure that my Tj should be reading 85º. If CoreTemp .95 sees it as 100º and TAT reads the same higher temps, does that mean TAT sees Tj 100º also and, thus, reading incorrectly and too high?

Thanks!

If you check the revision log on the Core Temp site, you will see that that the .95 release changed the Tjmax for L2 revision C2D to 100C. You can check which revision your CPU is with CPU-Z. I suspect that you may have an L2 revision C2D, which would explain the difference in temp readings between Core Temp .94 and .95. If not, then I don't know :?

Yep. I've got an L2. So that means that TAT and CT .95 are reading incorrectly and too high, right?

I hope that those temps are in farenheit, not celcius.

Those aren't the temps my CPU is at.

They're the throttle temps (max temps) that the monitoring programs see.

You missed the "Tj" part.

Correct. In this instance, if TAT is reading too high due to your L2 C2D, then it's inaccurate.

Computronix just said I was right.

Whew.

I thought TAT was crazy high!

I think that when it was realized that CT .95 saw the Tj at 100, but read temps that matched TAT, then the only conclusion was that with the L2 stepping, everything gets thrown off by 15º and then wackiness occurs.

Anybody know why Intel changed the stepping? Is there an advantage? Disadvantage?
