Hi Uncleweb.
I just finally read all the posts on the thread.
I like the work and effort you put within this tests.

I did some tests 2 days ago si I can helo you with the real Temps measured.
Sorry I couldnt post the tests before but I had a vacation weekend.
Now, Here is it:

Sorry for the pics, I was testing on a rainy day.
First, I took my UEIDT200 Thermometer and conected probe 1 to the CPU IHS and probe 2 just hanged on so you can see the ambient temps.
You can also compare ambient temps reported by my weather meter:



So, you see.... almost 25 Ambient.


Now CPU used is Core 2 E8400 so this can help with the tests.
The way I used the probe on the CPU was simple, just by one side touching the IHS of the CPU so I can measure the temp that way.
In fact, you did something similar by infrared termómeter, but I will meausre all the time CPU temps with my probe.




So I turned on the PC, wnet into the BIOS and set 1.125v CPU VID with all other voltages on stock VTT =1.1 and vNB on Auto as well as for SB.

As you can see, on BIOS CPU temp is 36 while actually is around 29 Celsius.








Now, for the tests, I used 3 Software:

1.- Core Temp (which is obviously the worst tool for Wolfdale it seems)
2.- Motherboard Monitor 5 (with FCG atachment so I can read DTS)
3.- Real Temp (by uncleweb)

Now, the screens I took will show the temps on idloe and Load. Tried SuperPi and Orthos on Both Cores.

Here CPU stock on idle temps:


While temp on sensor is about 27 degrees, Core Temp reports temps way to high and MBM reports temps below ambient.
Notice Real Temp is reportint 29 C but the calibration is - so, normally it would be around 31 Celsius.
If I put calibration on --:






Now:

While doing SuperPi. Thermal probe reports up to 29.6 Celsius.Core Temp again is way to wrong and if you see, Real Temp shows 35, and MBM shows 29 Celsius.
Seems like MBM is getting a good temp reading.
Let me clear that MBM as far as FCG told me, takes the Tjunction as 100º. While this doent works for idle, because it reports temps under ambient, seems to work on load.


Now, on orthos:


Notice Thermal probe is 32.4 Celsius.
Real Temp reports as 38 Celsius and again MBM reports 32 Celsius. So, it seems MBM gets good readings on Load.

Here on some minutes more after running:

You can see MBM says the exact same temp as Temp sensor.
At this point, Im starting to think MBM could work on load temps, but why is it so off when idling reporting always below ambient temps?










Now, I will set 3.8ghz with 1.32v on CPU.
Here the voltages set on BIOS:



Here on idle:

While Temp sensor shows 29 Celsius. MBM is below ambient, Core Temp is way too high and Real Temp shows 30 Celsius when using -- calibration.


While running SuperPi 1 core @ 3.8ghz 1.32v:


Temp probe shows 32.3 C.
While MBM is very close showing 32 C, real temp goes off up to 37 and I will not consider Core Temp which reads higher temps.


While running orthos @ 3.8ghz 1.32v:


Now, you see temp probe says 38.6 Celsius.
Now, neither of the temp programs report the temps acurately. Not even MBM which was working ok (or it seemed so) on Load temps.







While you can run the CPU passively, you can notice that the temp is really low for this CPUs. So, you can really take appart core temps readings and ignore them because I can even install OS with CPU without hetsink without problems.
Also, seemslike temps are lower than reported by any Temp program, and, for example, the MBM reports aparently acurate temps when load.
DIfference between MBM and Real Temp Tjunction is about 5 degrees.
- Also, MBM shows temps below ambient which are not possible when idling, and Real Temp gets good or at least, very close to real readings when idle.
- It seems that when adding voltage, all CPU programs show temp sclaling higher than it should be?




Well. I hope this can help you guys to make the best Temps reading program. I will make any tests requested if possible whenever this weekend, aganh, so dont hesitate to ask me some configs to test.
