Fan replacement for P4 Stock HSF

[Lamaman]

What would you guys recommend for a replacement fan onthe stock p4 2.2 intel HSF? or is this not possible - so a complete new HSF combination? any ideas? 3000rpm seems a little crappy for decent air cooling doesnt it?

Chow for now.

The stock unit is fine i have a p4 myself and it goes to 4874 RPM.

the hoter the cpu is the fan spins faster... what temp are u at idle/load?

 

[JuicyFruit]

how'd you get it run at almost 5k rpm? the asus probe gives me a reading no more than 2700 rpm.

Does that mean the fans on the retail p4 are temp regulated? I never heard that before.

 

[Detselom]

not 100% sure but i think so... or maybe every one's ultils record dif speeds

Yes, the retail P4 Northwood fans are all temp regulated. They normally run around 2700 rpm. Mine has run as high as 3900 rpm when things were hot.

Here's an excerpt from this Intel page about the retail HSF:

"the boxed Intel Pentium 4 processor fan heatsink uses a high quality variable speed fan which allows the processor to remain within its operating thermal specifications by running at different speeds over a short range of internal chassis temperatures. The processor fan operates at a low speed while internal chassis temperatures are low. If internal chassis temperatures increase beyond a lower set point, the fan speed will rise linearly with the internal chassis temperature until the higher set point is reached. As fan speed increases, so does the noise that the fan generates"
