Windows 7: Confusion with Tcase and TjMax

Michael, there isn't a thermocouple embedded in the IHS, but that is where Tcase would be read. As Steve said, the temps we see are calculations made by the software based on the DTS outputs.

That has been my understanding and it can cause a lot of confusion. What I don't understand is why Intel don't spec their devices based on DTS outputs. Why give a spec (eg. Tcase) if you can't accurately measure it?

This turned into an interesting conversation. I'm confused as much now as when I started it, but I understand it now. Just don't ask me to explain it.

I read a post by the author of Core temp. He explained a bunch of that and the fact that neither Intel nor AMD will give any info on what the readings of the DTS actually mean. They have to try to figure it out. I always thought that the DTS told how far you were from TJMax, so if you know what TJ Max is and how far you are from it, you can come pretty close to actual temp. But, maybe not.

I guess, if one of the 1155 pins in my CPU socket read the T Case, the motherboard would know. I read on the ROG forums that the AI Suite read Tcase. It either does or is way way off. It can give temps 20 - 30 lower than core temp, real temp or any other program.

Why Intel or AMD won't release that info is beyond me.

Right Steve, why is a temperature reading treated like some state secret?

Gary, I'm sure you know I cannot answer that. If I even knew the answer I would probably be executed at sunrise.
