How can I make my 8X8cm case fan run slower? I want a silent PC (I bought Passive HeatSink to my Pentium III 700 <58C full load> and to my GF2 GTS card <65C full load><max case temp 30C> and quieter cd rom drive <24X> ) and I just want the PSU fan (mine is quiet) and one exausting 8x8cm 1000rpm case fan... (mine <ANTEC Ball Bearing> runs at 2200rpm and it is too noisy!)
THANK YOU!!!

YOu can wire it for 7v by connecting the black lead to +5v.

2200 rpm is actually quite low... much lower than that and you might as well get rid of the thing

OK, normally fans have a red and black wire, which follows the normal color codes for DC which is that red is positive and black is ground (unlike AC where white is ground and black is live). Anyway, fans are normally 12v. But drives use 12v and 5v wires, where yellow is 12v and red is 5v. Hooking the fan to a drive connector, when you hook the red fan lead to the yellow drive lead (+12v), and the black fan lead to the red drive lead (+5v), you get a difference in electrical potential of 7v. That makes your fan run slower than if it were connected to 12v.

Got it! Is it safe?

you can wire it to a variable resistor so you can adjust the speed as you like.

GO to radioshack and tell them you want a potentiometer. Wire it in on one of the fan wires (doesn't matter which one). YOu can control the fan speed by turning the knob

Is there a synonym for thesaurus?

Really interesting the second link. Hope this helps.

The stock Intel P4 fan runs at 2200 RPM. And it cools very well. The reason is that it's large.
