It would be nice if you could wire a fan directly into a outlet... but unfortunatly, you cannot. Computer fans run on 12V DC power (at the most)... plugging a fan directly into an AC outlet would put a of AC power through the fan. I wouldn't want to know what the results of that would be

The simplest way would be to buy a 12v DC transformer and wiring the fan into that. Wiring multiple fans in serial should work if you want to run multiple fans. You could also acquire a computer power supply to give you more than enough juice to wire enough fans to make you go deaf. AT power supplies are the easiest to use in this application, but are hard to come by nowadays... maybe a computer junk store would still have a couple sitting around. ATX power supplies could be easily jumpered to work without a motherboard.
