Dubbed Cool-slim, this component cooler from Active Thermal Management will fit just about anywhere and is simple to use. You just put it on top of a hot component that needs more ventilation, and it pulls the hot air out, discharging it to the front and rear. Designed to fit into tight spaces, it’s only 1 5/8″ high, plus the feet can be removed, reducing its height to 1 1/4″. It uses all-electronic thermal switching circuitry. Just plug the probe and the wall-wart into the back panel, put the probe on the hot component and the cooling begins.
The list price of the Cool-slim is $225. All the specs are here: http://www.activethermal.com/page39.html
