1. A heat spreader, comprising:
a top surface, the top surface being thermally conductive such that the top surface is configured to receive heat from a heat generating component;
a bottom surface, the bottom surface comprises externally integrated fins;
a side surface, the side surface comprises a top edge and a bottom edge, the top edge of the side surface being physically coupled to the top surface and the bottom edge of the side surface being physically coupled to the bottom surface; and
a mounting element comprising a first portion and a second portion, wherein the first portion is physically coupled to at least one of the top surface, the bottom surface, or the side surface such that the first portion of the mounting element is contiguous with the at least one of the top surface, the bottom surface, or the side surface to which the first portion of the mounting element is physically coupled, wherein the second portion of the mounting element comprises a first side, a second side, and a pocket, wherein an opening is defined on the first side of the mounting element into the pocket, and wherein mounting holes are defined through the second side into the pocket;
wherein the heat spreader is configured to dissipate the heat from the heat generating component such that the heat flows from the top surface to the externally integrated fins on the bottom surface.
