Small circulating fan to cool amps

I have two tube amps that are on a rack system with wood shelves. Because of the space requirements of all the components on the rack, there is not as much space as I'd like to see between the top of the amps and the under side of the shelve above. Although I have not had any problem to date, I'd like to make sure it stays that way. These amps do throw a fair amount of heat. Has anyone had any experience with a small fan that could be used for ventilation? I looked at Radio Shack and although they had a number of small fans, the smallest and lightest ones were 12v. I'd much prefer to run off wall current, but I don't have alot of space in which to situate the fan. Their non-battery fans were just too big and heavy. Any suggestions?

Sounds like a good possibility. Note the fans you mentioned are about 3" X 3" X 1". Hopefully I could mount them in the space I have - but I would be close. I might try to find something even a bit smaller. Just to answer a couple of the questions above, I have vintage tube gear-Marantz model 9 amps and a model 7 preamp. There are four EL34s for each amp and they run in a row parallel to the back edge of the shelf on which they sit. Just measured and I have only 3" from the top of the tube cages to the bottom of the shelf above. Presume the wall wart referred to is the 12v 'cube' that plugs into the wall??

If you run fans with 12v trigger you can get a power adjustable adapter from radio shak and control the fans speed with diffrent power output, thus controlling any noise issues.
