Abstract
A heat sink assembly includes a fan, a heat sink, and a fixing device which attaches the fan to the heat sink. The heat sink has a plurality of fins. Four catches are respectively formed on four outermost fins, two on each of two longitudinal sides of the base. The fixing device has a base and four legs depending from respective corners of the base. A pair of protrusions depends from the base near respective lateral sides of the base. Four poles extend upwardly from the base near respective corners of the base. Each leg defines an aperture for engaging with the corresponding catch of the heat sink. The fan defines four through holes for respectively receiving the poles of the fixing device.
