ThermalTake NBcool T3000 Heatpipe Notebook Cooler review
Here's a closer look at the ridges and one of the heatpipes. The bottom of the T3000 also features four anti-slip feet. Unfortunately, these feet aren't properly attached to the aluminum plate - after a couple of days of testing, one of the feet already came loose.
Here's a graph from ThermalTake that explains how a heatpipe works. Inside the heatpipe is a fluid which turns to vapor as the heat increases. The vapor then condenses back into a fluid, returns to the hottest point and evaporates again. This cycle is endlessly repeated and dissipates heat from hot to colder zones.
This passive cooler is very compact and can easily be used on your lap. It should also fit in most notebook bags without a problem.
