Abstract
Method and apparatus for mounting a fan to a power supply in a computer are described. A camming handle pivotally connected to the power supply retains the fan and also provides an electrical connection between the fan and power supply. The fan is removably supported proximate to the power supply by the camming handle. Cooling requirements of the power supply dictate the type of fan selected for supporting within the camming handle. The camming handle pivots between open and closed positions with respect to the power supply. When the camming handle is in the closed position, the fan is disposed proximate, but external, to the power supply. A latch is provided for restraining the camming handle from pivotal movement when the camming handle is in the closed position. The camming handle includes two open slots which engage a ledge of the PC chassis. When manual force is applied to open or close the camming handle, leverage from the open slots simultaneously translates the power supply in the same direction as the applied force, thus engaging or disengaging, respectively, the power supply to or from the chassis.
