Electrical Question-fans...

Alright all you DIY-er's! How many of those little CPU cooling fans can be run off of one power supply? Also, what power supply should I use...12v?

Any imput would be a appreciated. I am setting up a 10 gal w/6x13w pc. The ballasts will be housed in two computer power supply housings, with the fans, and there will be 1-2 cooling fans running over the lights. I would like to run all the fans on one power supply, but I don't know enough about this elec-it-trickle stuff to know if I can do this!

Thanks in Advance!

I guess it would depend on what kind of voltage your fan is. Mine is a 12v fan so I'm running it on a 12V 500mA power supply that I found laying around. Really any power supply should work if you match up the voltages.

I would just find two seperate power supplies for 2 fans if I were you.

Most CPU type fans are 12v, so you'll need a 12v converter to wire them into. The way you tell how many fans you can run off one converter is the milliamps. Different fans draw more/less milliamps, and different converters handle more/less milliamps. I just installed 4 fans running off one converter on my 75g tank, and there wasn't anything special about the fans or converter.
