Difference between temp monitor progs

[Gibbo_GTI]

Hello all, after a little advice on monitoring the cpu temp. I have an ABIT IP35 Pro XE m/b which has uGuru monitoring and overclocking facility. When monitoring the cpu temp using uGuru, the temp shown is around 10 - 15 degrees higher than that of Core Temp. Which one is going to be the most accurate?

what CPU is it? Think you might have to manually set the TJmax value in core temp to get it reading accurately, I had to.

CPU is a quad q6600 @ 2.4 slacr. What should the TJmax value be for this cpu?

Saw these quotes in a thread i searched for "q6600 tjmax"

Might be worthwhile re-seating your heatsink as suggested but also you may want to change your tjmax setting in your Core temp programs to give you a true reading, check out this -

I have my tjmax set to 95 now but according to this it should be at 90, but i would rather be safe than sorry!

What you have done is correct, i have read through the article a few times and basically from my understanding you need to adjust the TJmax figure to get an accurate reading. This is a quote from the article -

"The only major factor which will affect readings is Tjunction Max. Since the 65nm CPUs were released, enthusiasts and developers of temperature monitoring software have debated over the Tjunction Max. It was hoped that Intel would disclose these details at the August IDF; however, we were to be disappointed. A few months later and Intel has finally decided to disclose the Tjunction Max for every processor in the Core 2 line, both 45nm and 65nm, as well as Xeon server CPUs."

If you download Real Temp - http://www.techpowerup.com/realtemp/ - it should sense that you have a Q6600 and automatically adjust the TJmax figure for you, on mine it sets it to 95 even though according to the intel data it should be 90. I would sooner be on the safe side though and have left it at 95.

So yes it will lower the temperature readings, how accurate are they, nobody really knows! but seeing as the data came from Intel it can't be too far out surely...

So take your pick, 90 or 95. Hopefully someone with a Q6600 will reply to this thread and let you know what they are using, or just use the real temp one!

Thanks, I had a read through all that. I set TJmax to 90 on Real Temp and it gave me figures of around 17 degrees C across the 4 cores. With it set to 95 its 20 degrees C at idle. Does these temps seem low for an unclocked Q6600 with Arctic Cooler Freezer 7 Pro fan + heatsink?

discrepency sorted

I did a BIOS update and with TJmax set to 95 on Real Temp, the temp reading is within 1 degree of the uGuru reading . System now idles at 28 degrees C in a pretty warm room.

Thanks for your help
