A heat sink assembly includes a heat sink (10), a fan fixing device (30), and a fan (60). The heat sink has a base (12), and a plurality of fins (14) extending from the base. Two threaded holes (18) are defined in each of opposite sides of the base. The fan fixing device has a frame (32), and four legs (36) respectively depending from four corners of the frame. A plurality of concentric guiding vanes (34) is formed on the frame. The guiding vanes have slanted surfaces for guiding airflow toward a central portion of the heat sink. An aperture (42) is defined in an end of each leg. A first screw (102) extends through each aperture and engages in a corresponding threaded hole of the heat sink. The fan is attached to the frame with a plurality of second screws (100).
