Heat sink assembly

Abstract

A heat sink assembly includes a heat sink, a first fan, and a second fan. The heat sink includes a first base contacting a first heat generating element, a first heat pipe connected to the first base, and a fin assembly. The first heat pipe is located in the fin assembly. The first fan defines a first input opening and a first output opening substantially perpendicular to the first input opening. The second fan defines a second input opening and a second output opening substantially parallel to the second input opening. The first and second input openings correspond to the fin assembly.
