Edit: It's got 2 fans which blow air out the back, its powered by usb (however, the usb end has a usb port in itself, so you don't waste a usb port), and it has 2 settings of hi or low though I leave it on high all the time.
i use the Belkin Cooling stand. it really works good on my girlfriend's Laptop "Toshiba"
i'm trying it now on my MBP to see if it works....if not i'll get the Antec cooler.
