I did not see any noise specs on www.radioshack.com but someone else may have a better idea.
The fan I used had two connectors on it that I soldered a length of lamp cord with a moulded plug in right on the end, and plugged it right into my receiver.

Radio Shack has a great selection of 110V AC fans ranging from 20 to 105 CFM. I have used one in the past and it worked very well. It was fairly quiet too, which is key in a theater setting.
