adjusting fan speed

[Miguelinho]

I have the stock intel/fan combo for my P4 3.0 socket 478 Northwood which runs too loud for my tastes. My tempuratures idle around 35C and can go up to 42C when pushed. At idle the fan is bearable, but after the computer warms up, it is too noisy.

I have considered switching to a quiter setup by upgrading heatsink/fan but in the meantime, I would like to see if my fan speed is adjustable.

I have been read about changing the fan voltages to quiet them down, but I do not know how to do this. One article stated that going from 12v to 5v can make a huge difference, although I do not even know what voltage mine is running at. I was also wondering if there were a way to control the fan speed in the BIOS?

Help me quiet down this monster.

42C when pushed is not bad but the noise bothers you.

The BIOS can offer some fan control but many opt to use a software program for fan control.

iirc, Speed Fan and Everest offer this for fan controll.

The real solution would be to buy a SK-90 at <$28 with a 92mm fan of at least 50cfm.

Just about every modern board (aside from some budget models) offers control of at least the CPU fan header, most have more.

If your board dose have controllable headers there should be an option for it in the BIOS. It can be in various places but it should be there somewhere, I'm familiar with Aopen and MSI's implantations, less so with others.

Even better then BIOS control however is SpeedFan. As long as the program recognizes the chipset used chip used to control the fans you can tie any controllable fan header to any readable system temp.
