Look Ma, no fans! Sorry, couldn't help ourselves...but the fanless CoolerMaster NotePal S laptop cooling station helps cool your laptop without fans, by increasing airflow around the underside of your laptop, where it gets hottest.
The biggest drawback is that it no longer allows you to use your laptop comfortably on your lap, but might create a more ergonomic situation at a desk or table. It retails for $30 and has 6 adjustable positions.
More pictures of the stand in action are available over at Gizmodo.
