A heat sink assembly includes a fixing device (10), a fin member (40), and a fan (50). The fixing device is integrally formed by extruding aluminum. The fixing device includes a base (12), two side plates (16) extending upwardly from opposite sides of the base, and an upper plate (18) connecting the side plates and being parallel to the base, thereby defining a space therebetween accommodating the fin member. Four threaded holes (22) are defined in four corners of the upper plate of the fixing device. The fin member is formed by continually bending a metal sheet to yield a concertina-like structure. The fan is box-shaped, and has four through holes (52) defined in four corners thereof. Four screws (60) extend through the through holes of the fan and engage in the threaded holes of the fixing device, thereby attaching the fan to the fixing device.
