Your growing in a cab right? Myself, I just use a circulating fan...works for me

its a standard pc fan by the looks, do a google search on "pc fan power wire"

or if your pc is always on and near your grow, run it direct fron your pc, lol
no seriously, it sould be easey, just look it up. i doubt a fan that size will move much air, though.

this is easy.....get a 12V DC adaptor(not AC) any ampage will work but jas to be 12V, splice both wires, do the same for fan, then wire them up.

you cant wire it wrong the fan will simply spin in reverse it that is the case switch the wires.

k thanks man, thats pretty well what i was wondering, if i wired more than one (2) to the same 12v dc adaptor do u know if there would be a big difference in the cfm output of each fan?

Damn, too late to edit, anyways, i was just lookin on ebay and i cant find an adapter that says "dc adapter" that all say "ac to dc adapter" are these the ones i want?

[invision]

yup those are them, i dont know about wiring more than one so hang on for that answer

there is no reason why you couldnt run more than one fan if your adapter is rated for enough amperage, most adapters are rated in milliamps and the pc fan you provided a link to on ebay says .6 amps wich is equivelent to 600 milliamps per fan.
if you dont have one that you can use already laying around there is several places that sell universal adapters, or you could even remove a power supply from an old computer.
