110v AC Cooling Fans

[balistidae]

Does anybody know where to find these things? I need to find one to replace the one in my aquatraders POS fixture. They sent me a replacement and it lasted about 7 minutes, so I dont really see the point in getting another replacement. I would also like to avoid having to get a computer fan/transformer setup seeing I need to keep this as low cost as possible, what a nightmare this has been. Thanks for any help!
