3.2E runs hot?

I've installed a 3.2E on an ABIT IC7-MAX3 motherboard.

I have the Intel heatsink and fan, since I'm using an OEM processor box.

At idle (the OS isn't even installed yet!) the BIOS reports a CPU temperature between 65 and 67 degrees centigrade.

Yeah, I did take the plastic off the heatsink pad before mounting the heatsink. I've checked carefully, and nothing (except the heatsink pad) is between the heatsink and the processor.

I know the Prescott chips run hotter, but is this normal? I found a thread about IC7-G Max2 boards reporting temperatures that are about 13 degrees centigrade hotter, but even if that's true I'm still running at 52 degrees, and that seems quite hot for being idle.

Any ideas about what to check? Are Prescott CPUs really that much hotter?

Yes, the 800FSB+HT Prescotts do run hotter than Northwoods. However, the temperature of your CPU in the BIOS isn't a true idle temperature. In Windows 2K/XP (NT and Linux too I think) when the system is idle, an HLT (halt) instruction is sent to the CPU effectively stopping it and lowering it's temperature. The BIOS doesn't have the advantage of the HLT command so the CPU temperature is a fair bit higher. Add in Abit's inability to report a realistic CPU temperature and things aren't nearly as bad as you think.

But Prescott is a hot chip, no doubt about it.

That's interesting, Coz. When does Windows execute a HLT? When there's no runnable threads? How does time spent halted appear in the Task Manager or in PerfMon when I'm looking at threads?

So you figure I should not worry about this 65 degrees centigrade report? When do I hae a problem? At 70 degrees? 75?

Sorry, you'll probably have to ask a software developer about those more detailed kinds of questions. I usually use the 'system idle process' as a guide to when the HLT instruction is in effect.

As far as the temps go, with the 'Abit factor' I mentioned earlier I'd only be really concerned if you were looking at load temps of 80*C+ when you're running a load through the chip in Windows. I know that sounds very high but the P4 can take it. Even so, have a look around for a better cooler!! :)
 
Thanks for your notes, coz.

It does sound very high. I ran Prime95 for a while and found that I was getting up to 76 degrees cenitgrade ... though not higher. And that's all buttoned-up, with the case together.

I found a thread on the Asus forum website where it seems like almost all the IC7-Max3 temperatures are really high. Even giving that thirteen centigrade adjustment, I'm at 63 degrees.

These high numbers make me nervous, but I guess I'll just keep an eye on it.
