i would only do so when playing music (and nothing else). thus, the cpu would run cooler and the cpu fan etc. wouldn't make as much noise. for games etc. underclocking is obviously invalid

see, i'm learning!!

I hope i didnt missunderstand you. But when you overclock something your cpu will run hotter, and your case will get hotter (if you have temperature sensing fans, they will speed up when you overclock). Underclocking really doesnt matter, and you should never consider this unless you own a laptop (really saves on battery life) or if your computer is overheating (aka freezing/locking up). Remember, you -can- damage your cpu, and especially only with air cooling it isnt a good option unless you fully know and understand what you are doing. You can also damage RAM/Motherboards as well. For games i would considering looking up VPU (graphics card) overclocking. This would have the most dramatic increase on games.


Edit: Completly ignore my post since i missread you, that you wanted to underclock >.<. Yea..your cpu will run cooler but your fan wont run slower unless you have a fan sensor that can read the temperature in your case/the temperature of your pc.

gotcha
i've got a lot of decisions to make:

1. how quiet do i need it?
2. how fast do i need it?
3. how much $ do i want to burn?

1. To help ya out..3/4 25db or below fans, and a stock heatsink/fan is pretty quiet, though if you wanna replace the one on the heatsink you can

2. Matters if you play games, or just search the web and listen to music. (also what type of games).

3.As much as you can afford

the more you spend the longer you have to wait to upgrade ~.^.

Also, i do enjoy awnsering retoricle questions.

Underclocking has its merits. By running at a lower speed, a lower voltage is required to power the processor, thus producing less heat. With less heat, uzziah is correct in believing less cooling is required, which in turn reduces fan noise when listening to music.

But a fan will run at its same speed even if the processor is running hot or cold unless you have a fan controller or a temperature sensitive fan.

right, and that's the kind of fan i'd have

As Iron_Dreamer mentioned the NF7-S is best for the Athlon XP. You could buy a mobile XP-M chip and potentially run it as low as 6 x 133 = 800MHz on only 1.5V.

You can also get power supplies without fans that use the aluminium case of the unit as a heatsink. Your hard disk may end up being the loudest component.

Actually the voltage goes down to 1.1v. I have run a mobile 2600+ chip at 1400MHz before completely stable at only 1.1v on that board.
