Abstract
A heat dissipation device includes a heat sink including a heat conducting portion and a plurality of fins extending from the heat conducting portion. The heat conducting portion has a base portion for contacting a heat generating device, and two wing portions extending from the base portion. The heat sink has two slits extending through two opposite sides thereof. A fan holder having a fan mounted thereon is attached to a face of the heat sink. The fan holder includes two brackets each having a rib engaged in a corresponding slit of the heat sink to thereby attach the fan holder to the heat sink, and a faceplate having the fan thereon. The faceplate has an ear secured to a corresponding wing portion of the heat sink by a screw and a tab extending upwardly beyond a top end of the heat sink.
