I can get you part numbers for graphics card fans if you'd like. Should be able to get you supplier info as well. Hell, I can get you the fans too, but that might be a bit of a hassle. :)

Anyway, I got the details of the super-small fan I was talking about before. It's a fan used in a certain Titanium computer. Ahem. :)

This is everything written on its label:

SuperRed
DC5v 0.07A
CHA2505CBS-A
Cheng Home Electronic Co.

So, the obvious small catch to me is that you have to take the step of lowering the voltage from 12. If you get prices for this part, let me know. This would easily be able to fit inside the empeg. Some of the fans used on graphics chips would only fit outside the empeg on the sled. And some of them have an integrated heat sink that makes up most of the fan's frame as well.
