Don't let a child sit on this one; it's for your laptop. The USB-powered Cryo V60 from NZXT keeps laptops, netbooks, tablets and other flat portables cool thanks to two whisper-quiet 75-mm fans with variable speed control. The fans draw warm air from a device's underside through the large center hole, sending it out the angled exhaust port that's nearly the width of the rear panel. A sturdy plunger switch controls fan on/off state. An included USB cable powers the unit, and it has a front LED and two extra ports (for power only, not data). The V60 works from any available USB port or AC/DC adapter (not included) and supports systems as wide as 16 inches. Rubber feet keep it all in place. $32.99 list.
