I bought a Celeron 330J on the 775 socket. The Intel fan usually spins between 2400 RPM and 3200 RPM depending on the CPU temperature. I found the fan to be quite loud, even at the lower RPMs. So today I bought the GlacialTech Igloo 5100 PWM heatsink/fan hoping it would be quieter.
The specs say it spins between 600 RPM and 3600 RPM. However, after installing it, the fan stays on a constant 3200 RPM, no matter what the CPU temperature is. I have gone into the CMOS and enabled the PWM (pulse width modulator) that supposedly varies the fan speed according to the temperature but it doesn't seem to do anything.
