adjust case fan speed?

[caveman017]

I have a 120mm fan which i would love to put in the front on my case, but running at 12v its louder then heck (well it is a 55cfm fan soo). Is there any way to change it to maybe 50% so its quieter?

Its got the 3 prong power (that plugs into the motherboard)

I have a Abit KN8

You can download speedfan...

did your fan come with a little switch that can change the speed of the fan to low,medium, high? If not, than your best bet would be speedfan

You can wire it so it runs at 7v instead of 12v.
