When are people going to learn how to use Speed Fan, do your reaserch before making the wrong guess. Speed Fan reads two different DTS (digital thermal sensers) sensers one in each core (always 15c hotter) and one (always 15c cooler) in-between the cores/on die, thats why Speed Fan gives two different readings.
There are "core temps" and there are "IHS temps."
Are you trying to be informative to me?
I know there are 3 sensors. I've read the C2D temp guide a long while back, so I know about the tjunctions (digital core sensors on the die) and tcase sensor (one between the other 2 or IHS).
Here's a screen cap using TAT (load on the CPUS), CoreTemp 95.4 and Speed Fan 4.33:
Now I specifically remember when CoreTemp Beta 94 read the same temps as Speedfan did. When CoreTemp 95 came out, it read similar readings as TAT. Now the readings are not exact, but both apps may poll the sensors at different times.
So when I went to CoreTemps website, they had a link for the fixes they did on it. And what ya know, they said the fixed a driver conflict in their app, and now it reads like TAT does.
Now as far as I'm concerned, I'd rather trust CoreTemp over SpeedFan. However I still use SpeedFan to easily see my 8800GTS temp on the task bar.
Edit:
Since I haven't read the Temp Guide lately, seems it has been updated. :lol:
Seems as though:
Note 1: Core Temp is an excellent utility, however, it has a fundamental flaw in terminology, which creates confusion in the CPU temperature community, by obscuring the distinction between temperature and specification. Core Temp shows Tjunction 85c (or 100c), which is an incorrect term. The proper expression is Tjunction Max 85c (or 100c), which is the term defined by Intel as shown above in the Specifications section, and as represented below:
Hmmm... so I guess the max tjunction is not to be reliable, which is understandable, but what about the core readings?
And as far as TAT:
Note 4: The software utility (TAT) Thermal Analysis Tool at maximum settings will simulate 100% Thermal Load, which would equate to Prime95 at 114% Workload. This provides the most extreme testing available for CPU and system cooling efficiency. Since TAT is coded to measure Notebook temps, it identifies a C2D as Pentium M. As Notebooks have no Integrated Heat Spreader, thermal scaling differs from desktops CPU`s, so TAT indicates ~ 2c lower, and depending on Variables, temps may be Offset by more than 15c. It is therefore recommended that TAT be used for extreme thermal testing only, and temps regarded as unreliable.
