Abstract
A fan holder (10) for attaching a fan (30) to a heat sink (40) includes a base (11) defining an opening (18) therethrough, two pairs of hooks (14), two pairs of posts (16) around the opening, a pair of positioning blocks (22), and two pairs of slots (15) defined in the base. The hooks depend from the base, and engage in grooves (46) defined through fins (42) of the heat sink. The posts extend upwardly from the base, and are received in corresponding holes (32) of the fan. Each post has a resilient engaging portion (24) and a notch (25), which allow the engaging portion to elastically compress and firmly attach the fan on the fan holder. The positioning blocks are formed under the base, on opposite sides of the opening. The slots are adjacent the hooks, and allow easy disassembly of the fan holder from the heat sink.
