To me there are 2 way's. You can use a computer power supply. It can run several fans, and has one built in. Or you can wire it up with a AC adapter like you use for a set of speakers or a battery charger.

Yeah you can regulate the speed, there are pc cases that have dials that adjust the amps for the fans.
probably just use a standard dimmer switch, which should work.

you can get these same types of fans at radio shack that are AC. This way you don't have to worry about figuring out the adapters and such. Just take a lamp cord and wire it up.

You can buy fan controllers from most PC hardware stores or online from Newegg.com they've got free shipping on a lot of small items and the delivery is great, plus if you manage to break it within 60 days they're usually really on top of things with RMA to get you a functioning unit quickly
 
If you go the charger/converter route,the side of one cord's plastic insulation will have a raised ridge on the side. That's the postive lead and the other is the ground. You can then hook it to a rheostat in a project box. Punch a hole in the box for the rheostats shaft,add an insulated knob to the shaft and you've got an adjustable fan.

You can pick the rheostat,knob and box up at Rat Shack for under 5-7 bucks,the box being the being the pricey item. Use a piece of circuit board inside and a rubber gromit for the hole to insulate the rheostat from the box. You could probably use a mint tin if you don't want to shell out for a project box.
