I'm using the following fan, which I purchased for $15 at a computer show:
SUNON
Super-Thin CPU Cooler

054006BH02
DC5V 0.7W
K9902
Made in Taiwan

I did some looking and found some interesting stuff relating to the fan. This link has a ton of thermal engineering info, as well as some obvious plugs for Sunon products.

This more specific link shows the specifics of the "Super-Thin CPU Cooler" line.

The fan is kind of whiny when it's behind the RF shield, which is probably due to restricted airflow. The Lasagna cooler has the same problem in this application. I suspect the Sunon fan/heatsink may be more available than the Lasagna unit, but I'm not sure. In any event, it's 3mm shorter than the Lasagna, so it may come in handy for some applications (taller CPUs?). The heatsink mounts to the CPU with thermal tape, so there are no clips to get in the way. I suspect this reduces thermal conductivity to a small degree, but the stock CPU does not get too hot with the heatsink/thermal tape combination.

Power for the fan is +5V, and it is tapped from the serial port connector, as shown above. The fan came with bare leads, so I simply soldered them to the surface mount connector.
