A floating heatsink is disclosed for components mounted within an electromagnetic enclosure. The floating heatsink includes an aperture within the enclosure wall against which a floating heatsink is disposed on the interior of the enclosure. The floating heatsink is dimensioned to overlap the enclosure around the aperture. A resilient bias member is disposed along the overlap between the floating heatsink and the enclosure. The resilient bias member acts as an electromagnetic gasket while urging the floating heatsink against the component. In certain embodiments the component is replaceable via a second aperture in the enclosure. The floating heatsink is particularly useful for overcoming the need for thermal compounds of heatsinks using the enclosure known in the art.
