Real Temp - New temp program for Intel Core processors
Unclewebb, I am the author of the Core 2 Quad and Duo Temperature Guide over at Tom's: http://www.tomshardware.com/forum/22...erature-guide#
I first became interested in this topic of "apples and oranges thermal fruit salad" in November 06. I wrote the Temp Guide in early February 07 because users were very confused, and no one else was committed to taking on the task of cleaning up this incredible mess that Intel has so inconsiderately dumped on us, their customers. Since the topic sorely needed attention, my Temp Guide was immediately Sticky'd, and has been a work in progress ever since.
I can appreciate what an uphill battle this is for you, and I'd like to congratulate you on a truly outstanding accomplishment. I've been following your work for the past many weeks, and have of course read every word of the "Novel". I'm convinced that you've produced some "breakthrough" results, and I find your work both fascinating and thought provoking.
Over the past 15 months or so, I've tested dozens of Core 2 Processors, and have accumulated a great deal of data regarding thermal behavior. I'd like to offer my validation to your findings by stating that the "canned" values of the popular utilities many times just don't make sense, nor do they show general consistency among variants. Based upon my own research and testing, I'm certain that you're onto something very promising here.
When I began reading your thread, and the posts of a small group of very bright Forum members here at ExtremeSystems, I was inspired to write a major update to my Temp Guide. You may find it interesting to know that although I had included the immensely popular utility "Core Temp" in the Tools Section of the Guide since the early days, it is no longer present in the updated version. I have instead included a link to introduce Real Temp in the Troubleshooting Section of the Guide, hopefully with your blessings.
I have featured and continue to support SpeedFan in my Temp Guide, obviously because unlike other popular utilities, (except Real Temp), it can be Calibrated. If you haven't read my Guide, there is a Calibration procedure in Section 9, which approaches the problem of Core temperatures quite differently, by shifting the emphasis away from dealing with the elusive variable of Tjunction Max in it's entirety.
First, a standardized Test Setup (similar to yours) is used for maxiimum cooling and Auto frequency and Vcore. Second, Ambient is measured, Idle power dissipation and CPU cooler efficiency values are plugged into SpeedFan, which yields an Ambient to Tcase Delta accurate to within a degree or two. Lastly, Prime95 is used to provide a 10 minute Load, and + 5c Offsets for Tcase to Tjunction Delta are plugged into Speedfan, which yields Tjunction values that are typically just a few degrees above Real Temp, and a few degrees below Core Temp.
The +5c Tcase to Tjunction Delta value at Load is based on the following Intel document - Thermal measurement in the Intel Core Duo Processor - http://eda-publishing.imag.fr/spip/IMG/pdf/TMI23.pdf - which I consider to be the "Holy Grail". After studying hundreds of pages of Intel documents over the past year and a half, I'm convinced that this obscure 5 page paper is as close as Intel has come in a single document, to inadvertently giving away their closely guarded "secret". The significance of this paper was also pointed out by rge back on page 13, post #319 of the "Novel".
I have a few other ideas I'd like to share with you as to how I may be able to help you in our common quest for the truth about the Tjunction Max debate. I will contact you by PM to discuss these thoughts, and likewise, feel free to PM me. In the mean time, please consider me to be you staunch ally.
Once again, outstanding work, unclewebb!:clap:
