Powering external DC fans

[daba]

Hello,

I'm looking for some sort of minimalistic device to power DC fans (4-pin molex or 3-pin) without use of my computer's power supply. Right now I'm using a external hard drive enclosure to power some fans, but I'd rather have something more suited to this purpose.

I borrowed my friend's
Sabrent USB to IDE converter, but it only works for hard drives. It seems to be missing one of the rails (in between the 12V and the ground).

Anyone know of a solution, preferabbly one that they know will work? Needs to be 4-pin molex or 3-pin.

The easiest way would be to get a 12V wall wart. Just cut the connectors off the fans, cut the connector off the power supply(unless you want to buy a mating jack to make it a bit cleaner), and wire it up.
