I would hope so, this means the recommended temp levels to stay within in CoreTemp will increase a bit, leading to *hopefully* higher envelopes with the OC'ing

I'm not overly sure of that.. I would think most of us do go for the max OC, somewhat regardless of temps.. Of course we don't run 24/7 like that, we do it just to see what the max oc is.. Then return it to a temp friendly oc.. It will effect a few, but the Xtreme OC'ers probably won't benefit from this..

The big hope in my mind is that this provides a little relief for those who have high idle temps with C2D's.. Losing 7C or so would be nice to know for them..

so.... instead of trying figure out your actual temperature, why don't you just use DTS? DTS is the amount left until your cpu hit's a critical failure, so of course there's no DTS max.

What CoreTemp, Speedfan etc, all their doing is just read the DTS, and subtracted from what they THINK the Tjunction is to get your actual temperature, which is why speedfan and coretemp are different. The Tjunction is set by the programer, not grabbed out of the cpu, or anything, but DTS is a precise amount measured from your CPU.

so then what in your opinion would be the max temp for that?

There is no Max for DTS, there is only a minimum.
DTS = the temperature left until your cpu will throttle and shut it self down. When it hits 0, then your pc will shut itself down to prevent dmg to your chip.

Here's a short write up by unclewebb over on XS

So basically, it's [Perceived TJunction] - DTS. When DTS is 0, we see the perceived Tjunction, and the system shuts down.

It would be interesting to just display DTS. Instead of measuring the actual temp, we could just measure how close we are to 0. Presumably DTS might be different for different types of chips, so knowing that i've got 10 or 15 degrees of play before shutdown would be interesting to know.

I'm going to add to the confusion. Is there certainty that CoreTemp reads the T-Junction correctly? I was under the impression that CoreTemp .94 and .95 just used different T-Junction values, but do we know if it's correct?

Here's why i'm asking ... a few weeks ago, I installed my E4300 (L706A if remember correctly), I think the HSF wasn't installed correctly, so temps were REALLY high. I could have sworn that CoreTemp showed a T-Junction of 85, but I hit 85 in TAT and the system didn't shutdown. If my DTS really hit 0, and my T-Junction was 85, I should have seen instant shutdown, but didn't.

Hi everyone!

Okay, I have been trying to figure this **** out for a while now. I think the problem some people are having with Speedfan is because as someone mentioned earlier, it reads sensors from all over the MB, and some MB have heaps of sensors and some don't have many.

I've been running Orthos for 2 hours now with my CPU at 3Ghz, and Speedfan says:

Temp1: 30C (MB?)
Temp2: 47C (CPU - t_case?)
Core 0: 55C
Core 1: 55C

Everest gives me:

MB: 30C
CPU: 47C
Core1: 70C
Core2: 70C

From this, I'm guessing that Temp2 in Speedfan and CPU in Everest are reading the t_case temps, and Everest is adding that 15C mentioned earlier that TAT and CoreTemp add to the Core0/1 sensors.

Also, during an earlier OC my Speedfan readings for Core1/0 hit 63C and the Temp2 (t_case?) reading hit 61C. What's interesting is that I had set my BIOS to sound an alert if the CPU hit 60C but it didn't happen, so obviously the BIOS is not reading the higher Core0/1 temps and is relying on the other sensor, which I think is t_case.

It's speculation, but perhaps the reason the BIOS alarm still didn't go off when Speedfan's Temp2 hit 61C is that Speedfan errs a couple of degrees higher as a safety margin?

Basically, as I stated I think people that are having trouble with Speedfan are not getting there t_case temps monitored for some reason, but also I think it is clear that the Core0/1 temps are much higher than the maximum limits stated by Intel, even when we take the 15C error in some systems into account.

i trust core temp,with tjun at 85c
