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?

The cooling of computers is a business all in itself.
You might do well to do some surfing in the world of computer cooling.
I'm afraid you might still end up using a 12 volt supply and don't be afraid to us a variac to control the fan speed.

That said, in the world of computer cooling exists a sub-culture regarding noise issues while cooling.
You'll want the quietest fan which moves the most air.

Cooling electronics is cooling electronics be it digital solid state or analog.

Guess I read too fast. What kind of tube amps are they. I want to look at how the tubes are arranged.

If you have a 12v trigger on your pre, you can run a small PC type cooling fan directly off the trigger output. Check the current requirement of the fan against the current available on the trigger.
