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!

It would depend on how many watts each fan draws but you should be able to connect 4 or so w/o any problem...
The power supply voltage will depend on the fan voltage but I do think most computer fans are 12v.

Yes, most computer fans are 12 volts, but DC volts. You can find 120 AC volt computer fans though, you just have to look harder.
