You will need to get a power converter. They aren't that much, and the price for them seems like a great deal after you pay near $5 for a single computer fan.

An AC to DC power converter from radioshack with a 100 watt rating or better will serve you well. Fan wires may need to be cut and wired onto the leads of whatever PSU you buy. PC fans come in all shapes and sizes. Get the one which fits best for your grow area. They also come in different RPMs... Higher RPM fans 1800 rpm and above can be aubible from a short distance. higher RPM fans like 3000 rpm fans can be heard from across the room and are quite loud. In my grow box I am using 1800 rpm, 120mm PC fans. I would go with a 120mm fan if you can. They push more air and do it at less RPM than a smaller fan. look on ebay for DC power supply, also look for PC fans by searching 80mm, 90mm, 120mm pc fan

Or you could just buy a 110v muffin fan to begin with.

splice the cables -- mix and match till it goes....make sure to unplug before changing wires =)

you can get better, assembled, fans for cheap cheap cheap (i got mine for 5 bucks at walgreens)

PC fans have 3 wires.

1 of them is black

2 of them are different colors

the black one should always stand alone.

the other 2 wires should be wired together.

you connect the black wire to the negative
wire on the charger.

you connect the other 2 wires to the positive
wire on the charger.

Make sure you tape the wires up individually to
keep them from touching, then wrap tape around
both of them together to keep them in place.
