The cooler itself is made out of aluminum, and has two large fans underneath a mesh material that blow air directly towards the underside of the laptop. The top has a very sturdy feel to it, and has a rubber material along the sides and along the bottom, where you would rest your hands. The overall feel and look of this, especially from the top, are excellent.
On the back of the Cryo S, there are three USB ports and a DC power port. The three USB ports are for the USB hub portion of the cooler, while the DC power input is to power the fans. Again, the fans can either be powered from your laptop via USB, or from the AC in your home. Finally, there is a control dial on the very far edge that allows you to adjust the fan speed from 700 to 1300 RPM. The Cryo S is slightly angled to help reduce the effects of an incorrect angle of attack on the keyboard, helping you to avoid the effects of Carpal Tunnel Syndrome.
