The exhaust fan inlet faces adjacent PCI or AGP cards and makes a great video card cooler for hot running 3D accelerator cards like the Voodoo, TNT2, GeForce256 and others. A quiet running brushless DC motor coupled with a high efficiency blade design is capable of moving 36 CFM (cubic feet per minute) of air. Power is supplied to the fan using a standard LP4 (hard drive power connector) pass through plug.
