9C to TJunctionMax

[VirtualLarry]

Just a note that you perhaps shouldn't be too afraid of thermal limits. Temps here reached 90F ambient, and my E2140s @ 3.2Ghz, 1.425v (BIOS) are hitting 9C to TJMax, and still going strong. According to CoreTemp 0.96, that's 91C.

That's risky. But for a cpu that cheap, it doesn't really matter :laugh:. Did you managed to cross the Tjunction?

That's a bit cozy 😛

But i've seen how hot OEM systems' CPUs run...they use crappy heatsinks that get very hot under load & yet i never see dead CPUs.

Personally i think voltage is a much worse enemy for CPUs than heat.

yea my CPU got to about 72C today when my ambient temps got to about 90-95C...
i just lowered my vcore and FSB back to 1.250 and 3.2ghz

damn i'm sweating too

95C ambients, whew.

how's life in hell?

 

[bryanW1995]

take a page out of aigomorla's book and run it there 24/7 until it blows up! :evil::evil: then report back to us with details.

yah larry, see what it takes to fry it, why dont ya? 😀

what max volts have you had it up to? Also, what are you cooling the case & cpu with? Maybe stop folding for a few hours & clean the case out & reseat the HSFs. heheheh

aka NYC this past saturday/sunday...
it was ridiculously hot and humid.

thank god my internet got DC and my dual folding SMP clients ended while i was away from home for 2 days or else temps woulda go to about 75-80C load

Hmm. Hit about 95F ambient today and I was encoding an xvid and temps didn't even reach 60C on my E2180 @3.2ghz. It was hot as hell in the room, too.

That's kind of the idea here. To see what happens with the heat.

Max volts is 1.425v (BIOS). I'm using a Hyper TX2 cooler, and a CM 330 Elite case with the built-in rear exhaust fan. Both case sides are off as well. The case and fans are clean with no dust. I reseated the cooler twice when I built the thing, no noticable change in temps.

I'm getting an AC in on weds, so this little experiment is going to be over then. 😛

 

[VirtualLarry]

AC is installed, temps are now 22C to TJMax. So I guess the experiment to push high temps is over. At least now I can safely burn DVDs again, I was worried about burning out the laser diode from the high temps I had before.

Did you have to raise the voltage as it got hotter? I remember when I did temperature testing that the breakdown region would change as the temperature increased, which would mean that the switching voltages would change depending on the temperature. I can't remember if the region change was proportional or inversely proportional to temperature; but based on what I remember from the changes of energy regions (basic quantum physics) with temperature the change should be proportional. But then I haven't done this work for 6 years or so, and I am a little fuzzy on the theory now.
