It's getting on my nerves. It's the stock cooler that Intel bundles with their P4 3.0 Ghz (800Mhz). It seems to be thermally controlled, so it ramps up to 4 or 5 thousand rpms when under a full load, depending on the surrounding temperatures, and since the speed varies, the accompanying whining noise varies in pitch. It's pretty annoying.
Does anyone else have this problem, or is it just me?
The sub 3GHz P4 bundled heatsink fans would run between 1500 and 3000 rpm. They're very quite. The 3GHz and up heatsink fans run between 3000 and 6000 rpm and they are noisy.
I have a 3.06 P4 and I couldn't take the noise for more than two weeks. I went out and got the Thermaltake P4 Spark 7 all copper heatsink fan unit with a three speed fan selector switch. It's 6000 rpm fan and I run it at the slowest speed which is 3000 rpm. It keeps my P4 under 55C at full speed and 40C idle. If I run the fan at full speed it knocks the cpu temp down another 10C degrees.
