Are these temps right?

[Matt]

The temp sensors in your cores don't actually give the actual temperature values. Instead, they give the distance(In degrees Celsius) to Tjmax(The temperature at which the processor will shutdown to prevent damage.) Coretemp and Realtemp get the temperature by subtracting the distance to Tjmax value from Tjmax. The problem is no one really knows what Tjmax is for any processor because Intel does not supply that specification. Realtemp uses 95°C as Tjmax, whereas Coretemp uses 100°C. In my opinion, 100°C is more realistic for a G0 Q6600 because if I use 95°C it sometimes shows my temperature 5°C below my ambient temperature when I first boot up my computer in the morning. You can use whichever program you want, you just might have to change Tjmax in Realtemp to get accurate readings.

(Oops, your're not using a Q6600 Anyways, I'm not sure what values the programs are using for your processor but there is probably a similar difference.)

Thanks to all you guys for your help. It's not that i was really worried about the temps, especially since they seemed normal than usual. It's that i wanted to make sure that everything was working normally and accurately before i started my first overclock. I'm sure i'm not the first one to feel nervous when about to overclock for the first time. :D

Thanks again.

Actually, ever since Intel released some whitepapers in August, we're reasonable certain that we know the TjMax values for each processor now. The latest versions of Coretemp and Realtemp have been updated to reflect those values.

There was a thread about that but the link to the Intel Paper does not work...
TjMax for 45nm Intel CPUs

Here's a working link that I found on the CoreTemp homepage. I think it's the right document but I'm not sure: http://documents.irevues.inist.fr/bi...79/1/TMI23.pdf

Thays a good explanation but the original one I linked had the actual tj max values listed. It seems that pdf. is no longer available. Check this article at AnandTech AnandTech
