Temps when overclocking

Also when I was having issues with my E6400, my mobo would not start beeping until TAT said 65º, not at 63 or 64, but once it hit 65. So TAT is off for my system.

Right now using F@H SMP with both cores at 100%, speed fan says they are running 45ºC. This is at stock 2400MHz. So I may kick it up some this weekend to see what I can get from it.

I noticed F@H SMP stress the system less than 2 F@H, therefore heats it less.

I agree...

using FAH SMP it read 45ºC in Speedfan
Setting both cores to 100% in TAT, Speedfan reads 48-50º (versus 53-55º in TAT), always 5º higher in TAT.

The difference in temps you are reading is due to the sensor you are using. ITAT uses an on die sensor inside of each core. The BIOS and most other software uses the sensor mounted between the cores in the heatspreader. it is normal to see as much as a 10C difference between them, in some cases the difference has been as high as 15C. This would explain why the system did not start beeping until TAT was over your set threshold.

Also I have been reading that while a lot of programs will make a CPU read as 100% none of them hold it at 100% always flucuating up and down. ITAT actually will hold both cores at 100% and keep them there until you tell it to stop. This makes it the best for reading the MAX unload temp.

An important point to remember with that however is that this will generate a high temp that you will rarely if EVER reach with normal use.

Overall what I am looking for is a consitent and standardized method of temperature detection and ranges. It would appear that ITAT offers the best solution for this. Since it will work the same with all Core2 processors, unlike various BIOS readings which can vary from between BIOS revisions let alone different model and brands of boards.

Thats what i like about Speedfan is its ability to reads these temps as seen in the BIOS and most other monitoring programs. It is a bit confusing at first with Temp1, CPU1, Temp3, and HD0 but overall it seems much better all around plus gives you the SMART hd info among other things.

Sadly enough Speedfan is not updated frequently though. I'm glad it works on my system, and the latest version gives me the first core temp and not the CPU temp which is great. :)

I just downloaded Speedfan 4.32, and so far it's a mystery to me if will control my fans or not. Of my many fans, I have 3 connected to the board (CPU, GPU fan and another 120mm fan). I messed with what I'm guessing are the fan speed controls, and I don't know if anything changed or not. As far as temp readings, temp1=35-37°, temp2=40°, temp3=41°, temp=2°, HD0=31°, HD1=36°, core=32-34°. In comparison, on the CPU temp, Everest seems to be within 1-2° of what Speedfan says (assuming temp1 means CPU temps). Everest is also easier to read though. On Speedfan, I don't know exactly which reading corresponds to what component.

one is system temp from a temp sensor on the motherboard somewhere, I think core is the cpu temp but I would be wrong..
also like mentioned above, some procs have a temp sensor between the IHS and the core and another in the die/core itself.
So in your case I suspect temp 2 and 3 are the temps from within each core die... temp 1 is likely the one between the IHS and core. HD0 & 1 are hard drives of course and core may be the ambient temp sensor... hard to know for sure though

Ok, I was messing with it, and it seems it will control CPU (f#1), PMW IC (f#2), and chipset (f#3), and it works to change speeds even though I usually use SmartGaurdian to control them. I could see speed changes while looking at SG and messing with SF.

What do the green arrows and blue check marks mean, and why do they change? I've also seen a red arrow pointing up sometimes. Temp#1 seems to be in line with what Everest shows as CPU temp.

And on the "clock" feature, when I go to input my DFI board, it only gives me the option of an AK-76SN model. On the other makes, it also only gives one or two board model options.

Arrows mean climbing or going down temps.
Forget SpeedFan for overclocking.
You can rename the sensors so you know what they are.
