Thermal Specification for P4 3.2 Supporting HT

[AppleCertifiedPro]

Hi, I've had this P4 3.2GHz Ht CPU for a good 3 years or more. My P4 obviously gets hot as it is on the stock cooler. I haven't been bothered to buy a third party cooler as its useless wasting money on this old block of silicon. I just wanted to know what the average operating temp should be for the CPU. If it is possible i would like to know what the maximum operating temperature is for the CPU, which won't harm the CPU.

On idle my CPU does 49-50C. On 100% load it gets in the 60's or above at times.

Any suggestions are appreciated

Thanks!

Well, there are a bunch of 3.2 GHz P4 HTs. Run CPU-Z and tell us which one you have. The Northwood 3.2C HT is the oldest one, then there are a boatload of Prescott 3.2 HTs: socket 478 1 MB L2 3.2E, 3.2F, socket 775 1 MB L2 540, 541, socket 775 2 MB L2 640. The last P4 3.2 HT is the Cedar Mill 641, but that's newer than 3 years, as would the "numbered" Prescotts.

Here are the maximum temps for the various chips:
Northwood 3.2C HT: 70 C (86 W)
Prescott 3.2E: 73.2 C (103 W)
Prescott 3.2F: not listed...
Prescott 540: 67.7 C (84 W)
Prescott 541: 67.7 C (84 W) <- this is the same as the 540 but 64-bit.
Prescott 640: 67.7 C (84 W)
Cedar Mill 641: 69.2 C (86 W)

I never realized that the Prescott dissipated 20w more energy at 3.2Ghz than a Northwood. Geez...

I have a 2.8C but haven't used the stock cooler for quite a while. I know that I got into the 60s with the stock cooler under load. I think my idle temps were a little lower, but not much. Now I have a Zalman 7000 and overclocked to 3.15GHz currently and it doesn't get much above 52C.

I know with the Northwoods, if they hit 80 they would throttle and if that didn't lower the temp, they would shut down to prevent damage. I don't think that your temps are anything to worry about. It just kind of limits your overclocking potential.

Well its funny because it hasn't been OCed at all. All stock. The only problems is the fan speed. For example when i am playing CS (Counter Strike) the CPU hits about 60-65C and the fan speed is about 2700RPM or below. However, as it is winter over here the ambient is quite low in the 20C's or below. Is the ambient temperature affecting the fan speed which as a result affecting the temperature?


Intel P4 Supporting HT on the 478 socket at 3.2GHz thats the CPU.

And the 65 nm Cedar Mill only managed to get back to the heat level of the Northwood? Taken in this context AMD's first 65 nm Brisbanes look like a smashing success compared to Intel's first 65 nm parts.

Also, regarding the original question, I have a 3.2C (Northwood) running @ 3360 MHz that idles at 41 C, and gets up to maybe 63 C at load on the oh-so-wonderful Intel fan & heatsink.

I also use Asus Probe II to moniter my temps. I think that program and that manufacturer is the problem. I think ill download core temp and see how it goes.

You could try to get a utility that will allow you to control your fan speed. I don' t remember off the top of my head how fast the stock fan will go.
Either your motherboard manufacturer might have one, or you could look for a generic one online. They should be available for free download. If you are looking to help your temps without investing much money, you could get som good thermal compound like Arctic Silver or something. The stock HSF for my P4 used a thermal pad which typically doesn't work as well.

The stock fan hits a speed of about 4000RPM, at full 100% load. I think ill get my hands on some AS5, see if it will do anything.
Thanks for the suggestions! Greatly Appreciated.
