Fan for enclosed audio cabinet

The audio gear within my new (enclosed) audio shelf is really a little hotter than it probably should be.

Are there any choices out there for small-ish fans with a standard plug that could plug into the back of my reciever? What I had in mind was something similar to a CPU case fan.

Thanks in advance!

erm, i know there are some fans out there to cool your system, but they're bigger than you suggest, this one for example:

just wire to a normal 2 prong plug, and you're set
