63 is core temp, which is internal. Intel has rated the e4300 at 61.4 @ the heatspreader. Mobile chips are rated differently, they don't have a heat spreader and are rated at 100 on the chip. Before core temp or any of the internal readings came along, all we know is that I would be running Temp 1 (see OP) which is only 43 at load.
e4300 spec
T7100 spec
I'm trying to figure if Coretemp is even right. Coretemp says on its page that it uses Tjunction. Tjunction is for mobile chips. Thermal Specification is what Intel goes by for all other chips. Maybe the coretemp guy just didn't mention he has different algorithm for the 2 different chip styles. I don't know.

If Tjunction is different than what Intel has provided for heat spreader equipped chips, then how do we know what is within tolerance? I will say that the system is stable as can be and I have no worries about how it's running right now. I am curious to know if I have more headroom or if I am at the limit for this current configuration.

Why don't you guys do some reading and see that temps over 60c are very common on C2Ds. These chips don't throttle until they reach their TJunction which is 85c and 100c, depending on the chips. Intel's thermal specifications are what a CPUs max temps should be based on it's stock clock speed and voltage, considering an ambient of 50c.

Perhaps reading Intel's pdf will help: http://download.intel.com/design/pro...s/31327804.pdf

And Yoxxy @ Anand gave a very concise explanation. Check it out:

I did do some looking, didn't find that though. Thanks Schuey.

Ya they are rated at 61.4c at the heat spreader. But the cores run at those temps too. People have done test, and at most there was 1c difference between the cores and IHS.

If your running 63c core. You can bet your IHS is 63c too. Which is over the limit.

Also don't forget those temps are under normal conditions. Not overclocked.

Lots of people run them hotter than what they are rated at. That is their choice.

I personally can't afford to go out and buy a new cpu every year, or buy a new cpu when ever one dies.

So I play it safe and do not run it hotter than Intel rates it at.

How can 63c overclocked be fine?
because that 61.4 for is fore Tcase temp not Tjunction.

If his Tcase temp is in the 60's then he should worry.

damn nice link. I didn't know the watts change as you overclock and you Tcase changes also.

I will try to look for a link to where I saw a test of removal of the HSFs..
here it is: very interesting regardless of the source being Toms
