Add-on heat sink

An add-on heat sink, comprising:

• an elongate planar base having a top surface, a bottom surface, and peripheral edges;
• a plurality of heat sink fins extending upwardly from the top surface of the base and across the top surface at least partially between an opposed pair of the peripheral edges;
• at least one magnetic layer disposed on the bottom surface of the base, the magnetic layer being adapted for attaching the base to a heated structure, wherein said at least one magnetic layer comprises at least one pair of first magnetic pads attached to the bottom of said base;
• at least one pair of spaced second magnetic pads adapted for attachment to the heated structure, the first magnetic pads being magnetically attachable to the second magnetic pads;
• at least one pair of third magnetic pads disposed on the top surface of said base;
• a fan having a fan housing, the fan housing having a bottom surface;
• and
• at least one pair of fourth magnetic pads attached to the bottom surface of the fan housing, the third and fourth magnetic pads being magnetically attachable to selectively secure the fan atop the heat sink fins in order to facilitate heat dissipation through the fins, wherein said fan at least partially covers said plurality of heat sink fins, said plurality of heat sink fins at least partially projecting within the fan housing.
