drums101,
I believe that I've already answered this question:
Although maximum Core temperature (Tjunction Max) is 100c ...
October of last year, following the Intel Developers Forum (IDF 2008) held in Taipei, Taiwan, Intel finally made it clear that the Tjunction Max value for your Q6600 G0 is 100c, which is the default value shown in Real Temp. If you'd like further confirmation, then ask the author of Real Temp, Kevin Glynn (

The Real Temp thread at XtremeSystems is the single most informative source available anywhere on the Internet concerning Intel Core temperatures. Since the early stages of developement, and throughout the past 14 months, I have followed all 141 pages of the Real Temp thread, and have been in correspondence with Kevin, in order to share our research and test findings. You'll find that he's very responsive, so if you post a question on his thread, he'll answer you in short order.
In addition to being the ONLY core temperature monitoring utility which offers Tjunction Max calibrations AND Tjunction Idle calibrations, Real Temp is the only freeware utility available which is based upon real-world testing, as well as analysis of Intel's engineering documentation. Real Temp's Tjunction Max tables are accurate for each processor variant, which is precisely why I endorse Real Temp in my
Core i7 and Core 2 Temperature Guide, and recommend it over Core Temp.
Keep in mind that Tjunction Max is not an exact figure, but is also referred to by Intel as "Tj Target" which may vary from part to part, and core to core, and is evidenced by differences in individual core temperatures that are commonly seen on the same processor. More exactly, Tjunction Max is the "average" or "mean" Core temperature of all Cores, with the exception of disregarding an individual Core which is obviously far out of calibration tolerance.
Tjunction Max values are affected by Digital Thermal Sensor (DTS) variables such as factory calibrations, slope error and linearity. This is why Tjunction Max (maximum Core temperature) is a round figure, such as 100c for the Q6600 G0, or 90c for the obsolete Q6600 B3, while Tcase Max (maximum CPU temperature) is an exact figure to the tenth of a degree, such as 71.4c for the Q9650 -

Further, since the calibration method I developed for my Guide does not require or use Tjunction Max values to achieve CPU temperature and Core temperature accuracy, the calibration results show that the actual Tjunction Max for the Q6600 G0, as well as the Q9650 averages between 97c and 98c. Conversely, all the Core i7 processors that I've tested are spot-on at Tjunction Max 100c. I have tested and calibrated many Q6600 G0's, Q9650's and i7 920's, and the results have been verified as consistent and repeatable.
Since you're interested in achieving the most accurate temperatures for your rig, my best advice to you is either go with 100c, or plug in a closer value of 98c, or perform the SpeedFan calibrations detailed in my Guide to find the exact Tjunction Max value of your particular Q6600 G0.
