Re: Making Fan On/Off switch
FWIW Noctua uses 1/4w resistors on their fan speed lowering pigtails. So I am sure 1/4w will do it. Just start with a 1kohm and if thats still to fast move lower to an 800, and then 500.

Re: Making Fan On/Off switch
Light dimmer switches work exceedingly well.
They'll go 100% all the way to off.
Check my Vento 3600 thread to see some pics of my ghetto fan controller. although mines made for 115v fans and not 12v
i like some torque with my fans.
[edit]
i don't see a reason why this wouldn't work for a 12v line, i've done it before with 110v rheostats and its worked... still working matter o fact in bud420's computer.
These volcano12 fans pull some dank amps/wattages.
Volume knob off a stereo would work flawlessly to. there all 12v rheostats.

Re: Making Fan On/Off switch
yes, the dimmer switch you posted would work just fine for 12v. all it is is a variable resistor. just because it's rated for up to 240 V at whatever amps, doesn't mean you can't use it with much lower voltages.
it would sort of be like using a nice 1000w power supply with an atom mobo. it won't hurt anything, you just won't be taxing it by any stretch of the imagination.
