Hi there, If you take a look at my thread
http://www.icmag.com/ic/showthread.php?t=18478&page=6&pp=15
You'll see i wired 4 Pc fans together, for the power i used an old Mobile phone charger
(12V)...then just used those plastic blocks (for wiriing car stereos) or u could use scotch blocks i think they are called....
maybe even with a switch might help
Hope this helps

computer power supply. But yeah just take a convertor(those big boxy plug things) and read it. Kepping on reading as much as you can until you find a 12v output one. Now cut the end off so you have a long wire attached to the plug. The red wire on your fan connects to the wire on the converter with a stripe. then connect the remaining 2 wires together. If done right your fan will spin, if not you just burnt out the motor. These fans usually only work 1 way.

well that depends on the charger
some phones use low voltage like 4 - 5v and a low amp rating (few hundred Ma)
others are 12 - 14v and sometimes over 1a output
the latter are Ok to run the fan's from a PC as they require 12v and about 500Ma - 1a to run depending on the model
I recommend an old AT or ATX power supply from a PC though as it has the correct output
and are built to run for long period's
phone adapters get very hot and are a possible fire hazard if there running higher
than there designed use
better safe than sorry
OP
yes you can use a phone charger or a AT or ATX power supply but keep in mind that if you use a power supply from a computer(AT/ATX) that you most likely have to keep it in your grow cab thus raising the temps in your cab and as many of us have found out the heat from the light can be hard enough to deal with never mind adding more heat to the cab. If you are going to use a cell phone charger make sure that both the fan and the charger are rated for the same volts, also like GotTheBlues said when wiring your fan red fan wire connects to black with white stripe charger wire if done wrong better head down to radio shack and buy another fan.

If you dont want to spend all that juice on one little fan then pickup one of these @ radio shack. This one will run a few fans for $17
