Abstract

A heat sink assembly includes a heat sink (50), a fan (10), and a fixing device (30). The heat sink has a chassis (56) which defines a pair of diagonally opposite grooves (58) in respective opposite side walls thereof. The fan defines a vertical through hole (12) at each comer. The fixing device has a rectangular base (35). A pole (32) having a barb (36) extends upwardly from each comer of the base, for engaging with the corresponding through hole. A pair of legs (40) depends from each side of the base. A catch (42) is formed at a distal end of each leg, for engaging with the heat sink. Two guard boards (46) depend from each side of the base. A pair of bosses (48) is formed at distal ends of two diagonally opposite guard boards, for engaging with the grooves of the heat sink.
