Intel E4500, 77 Deg C Full Load too Hot?

When running IntelBurnTest, my cpu core temps both go up to 77 Degrees Celsius. Is this temperature OK?
 
Its a bit hot, though if you said you were in a hot room and running the stock Intel cooler, that would be about right.
 
77C a bit hot? lol might want to check what the thermal limit is on that cpu.. should be posted on intels website.. because if its near or within that thermal temp it will automaticly start downclocking its self or even shut its self down to protect the cpu..


edit: but what program are you using to read those temps?
 
With the burn test that is about right.

@sirmonkey1985: they won't always downclock or shut down, sometimes depending on what mobo and bios setting you have. my e8400 has gone over 80c before, using burn test of course.
 
interesting.. not sure id really want to see my cpu hit those temps :p if it was an athlon XP id have no problems with it.. but with a lot of these newer cpu's the thermal limits seem to be much lower..
 
Thanks for the info everyone.

This only happens when I run IntelBurnTest at max RAM using several "loops".

I should also mention my voltage is set just over 1.5 volts.

Edit: I am using Core Temp for temperatures, ver. 0.99.3
 
For some facts.

Per Intel at the IDF
45nm Desktop Dual-Core Processors
Intel Core 2 Duo processor E8000 and E7000 series - 100°C

45 nm Desktop Quad-Core Processors
Intel Core 2 Quad processor Q9000 and Q8000 series - 100°C
Intel Core 2 Extreme processor QX9650 - 95°C
Intel Core 2 Extreme processor QX9770 - 85°C

Note that Tjmax is when the cpu just thinks it is hot and signals "spin the fans 100% !!! "
5-20C above that is the Catastropic Thermal Trip point where the cpu will shut itself off.

Each CPU is adjusted individually at the factory for Tjmax so the 100C is the "family" value, your individual cpu may vary by a few deg.

77C is nothing to worry about. Delta to Tjmax is what you should be looking at and it is the thermal headroom, the number of deg C until you reach that factory set "Sping up the fans" value. The higher the number the better under load and as this number is derived directly from the cpu with no additional math it is as accurate as you can get and is unique to your cpu (the factory trip settings are taken into account/used).
 
Thanks Bill!

According to Core Temp My Tjmax is 85 degrees Celsius. So far my system is stable, with my 2.2 GHz chip overclocked to 3.3 GHz. Since my max load temps are well below 100 degree upper limit, I am relatively comfortable.

Thanks for all replies.

The E4500 max temp is 73 celcius before damage occurs, this comes right off the Intel webpage. Seriously, if your running it stock and its over 60c even with stock cooling your doing it wrong. Stock full load in my horribly hot room it never goes over 55c.

Careful analysis of that web page will reveal that they are talking about Tcase. That is a different thing entirely There was and most likely still is a typo on the temp heading for that web page. I have reported it to Intel but last time I checked a couple of months ago it had not been corrected. If you popup the help/description of the temp rating it should become clearer. Tcase max is the max temp recorded dead center on the top of the IHS and is the max temp at that point to remain in Intel's recommend TDP envelope. Tjmax is not documented in any Intel public technical literature (the values in the previous post where released at the Intel Developer Conference just recently - only 2 years late ) but Tcase is and that is what is on the abbreviated spec page you are looking at. They do list Tjmax for the mobile CPUs and someone made a mistake in the heading for the desktop ones.
