The Zodiac II cooler itself uses the sun design along with the constellation symbols as a fan grille. There are twelve symbols in total and it appears that there is enough space for air to flow through in order to cool the laptop. The top of the cooler is 2.2mm thick aluminum and measures 290 x 240 x 38.5 mm while the underside is made mostly of plastic. There is no design on the underside which makes sense since you should rarely see it. The fan used to push air through the Zodiac II is a sleeve bearing equipped 120mm piece and runs at roughly 800 RPM. The noise generated by the cooler is 25dBA at the maximum fan speed. The key is how well does this low speed fan help cool the innards of your netbook or laptop.
Two USB ports, a 5V DC power input, and a toggle switch are all found along the left side of the cooler. Either USB port can be used to power the device, but I was unable to test if the 5V worked since no adapter is included. The toggle switch only controls the fan. The laptop sits comfortably on top of the cooler.
