You want a quite fan like is found in a computer. Radio Shack has some 12V and 120V I believe but you will find many online. You can set them to run whenever power is available or you can add a thermostat so it only runs when the temps reach a certain level.

This is my favorite answer. When I was younger I built custom car stereos. My wife had one in her car and the amp would overheat and shutoff on a 100 mile trip. The amp had a clear plexiglass top so you could see the components. I bought a 2 inch computer style fan from Radio Shack and cut a hole in the amp cover to match. Glued in place so it would draw the air out of the unit rather than pushing it in. Wired it so it was only on when the amp was on. 3 years later and it was still going without issue till the day we sold the setup.
