A heat sink according to an embodiment of the present invention can be attached to any device without printed circuit board (PCB) modification. The heat sink may clamp on device edges, which does not stress solder balls between the device and heat sink. The heat sink may be configured to be installed to or removed from the device without special tools. The heat sink may be extruded, machined, or die cast aluminum or other material to reduce part and tooling cost, and may be black anodized to be electrically non-conductive. A single-piece embodiment eliminates a need for a separate clip, thereby increasing heat transfer by as much as twenty-five percent or more over heat sinks employing clips. Further, wavy fins or other heat dissipation configurations may increase heat transfer by at least eleven percent, for a total heat transfer improvement of at least thirty-six percent over a two-part heat sink.
