Abstract: A cooling assembly includes a fin, a fan retained above the fin, and a housing. The fin includes a bottom surface for contacting an upper surface of the integrated circuit and an upper surface from which a plurality of ridges extend, each two adjacent ridges defining a channel therebetween. A plurality of venting openings are formed in a top wall of the hollow housing. A plurality of snapping members project downwardly from two mutually facing side walls of the hollow housing and each of which having a distal flexible snapping end for releasably engaging with an underside of the integrated circuit. A pair of ribs are formed in an upper section of each of two mutually facing inner sides of the side walls of the hollow housing, the distance between opposite ribs being equal to a width of the integrated circuit. A plurality of oblique flexible pieces extend from an inner side of the top wall of the hollow housing.

Abstract: A fin assembly includes a fin, a pair of mounting pieces for removably mounting the fin to an integrated circuit. The fin includes a bottom surface for contacting an upper surface of the integrated circuit and an upper surface from which a plurality of ridges extend. An extension extends downward from each side of the bottom surface, such that the distance between the two extensions is equal to the width of the integrated circuit. On at least one of the mutually facing walls of each outermost ridge and its corresponding adjacent ridge, a groove extends along the length of each ridge. Each mounting piece includes a base and two beveled sides each extending downward to form a distal snapping end. A pair of pins extend upward from a top of the base, such that a fan may be mounted by passing the pins through pin holes in the corners of the fan.
