The most-effective laptop cooling devices we've seen involve fans that suck warm air away from the laptop's bottom. Both the Antec Notebook Cooler and the smaller Antec Notebook Cooler S use dual fans, but the $29.99 Belkin Laptop Cooling Stand manages to offer effective cooling with only a single fan.
Measuring 11.5 inches wide by 11.25 inches deep by a little more than one inch high, the Belkin Laptop Cooling Stand is best suited for 15-inch or smaller laptops. A larger desktop replacement will have to balance on top, extending over the left and right sides by several inches. Rubber pads on the top prevent slippage, but a wider cooling stand, such as the Antec Notebook Cooler, would be a bit more stable. For the aesthetically oriented, the Belkin's white, curved design is a nice change from the gray/silver industrial look of the other devices we've looked at.
A small plastic panel folds out from the bottom of the device, elevating the rear slightly for better ergonomics. The single fan, powered by a USB port on your laptop, sits in the middle of the slightly concave cooling stand, and hot air is channeled out to the left and right sides of your laptop.
