The Cougar Dual-X is designed to push a large amount of air while maintain silence. The Dual-X accomplishes this by using a hydraulic bearing so there is less friction. The nine blades of the fan have two layers and are rigid material. The blade design also features claws. The combination of these features allow the fan to produce more pressure while decreasing turbulence and noise levels. Other noise reducing features are rubber pads and rubber fixed pin mounts to reduce the vibrations that are transferred into the chassis. Accessories include a 3-pin to 4-pin Molex fan adapter, tool-less fixed pins, and fan screws."
