CPU temperature levels enquiry - Intel Pentium 4 Extreme Edition 3.2Ghz
Hi,
I have a Pentium 4 Extreme Edition processor 3.2Ghz 478-pin and ASUS P4C800-E Deluxe motherboard. Together with my processor I have a Thermaltake 6000rpm fan and copper (I think) heatsink, and with Arctic Silver 5 thermal paste (that I applied about 1-2 years ago when I built the computer).
My processor with the fan at 6000rpm operates at 45(idle) to 60 (100% usage) degrees Celsius. Lately, I thought why not lower the fan to gain from some noise reduction, hence I lowered it to 2500rpm. When it is idle it operates at about 45-50 degrees C, but when it is being used 100% (e.g. video games), it quickly goes to 70 degrees C, and I am worried.
What is the maximum temperature it can operate WITHOUT losing any performance? Is a temp of 70C normal? Is the processor safe under these circumstances? (Note: the processor is NOT and NEVER has been overclocked).
Please advise. Thanks in advance.

The maximum recommended case inlet temperature for P4's is 70C: http://support.intel.com/support/processors/pentium4/sb/CS-007999.htm I would say get a Zalman 7000, 7700, or 9500 cpu cooler, which use large fans that run quieter.

Ok I will consider that.
So the processor works at full performance at 70C?
Also, what happens if I pass that? Will it be damaged or turn performance down to protect itself?

>So the processor works at full performance at 70C?
Yes, but remember, that's inlet temperature. The cpu can stand higher temperatures, up to 85C, I believe.
>Also, what happens if I pass that? Will it be damaged or turn performance down to protect itself?
The P4's come equipped thermal protection in the form of a diode to slow the cpu down if it gets too hot, so it is very difficult to overheat one and permanently damage it.

At what temperature does the performance start to fall?
here some more info on the temperature :

>>>(Lowest: P4 Extreme Edition 3.2GHz with 64°C, highest: P4 Willamette 1.8GHz with 78°C).<<<
Does it mean that the extreme edition has the lowest MAXIMUM temp of 64C?

as i read it, yes.
ASKER
64C I think is quite low for a max temp of an Extreme Edition. Callandor's values seem more logical to me - gotta cross-reference then.
Actually, it says 64C - 78C, so the actual temperature depends on the processor.
ASKER
Ok so staying at 70-71C (100% usage) is safe/recommended?
No - it is not - it is a MAX temperature

Ok but the case already has about 14 fans/blowers/coolers in total, working at the moment. Basically the weather also contributes to this - it's pretty hot this season. I will consider a more silent fan. Thanks for your help.
