A system is provided for heat sinking and environmental dissipation of heat generated by one or more ICs mounted to a printed circuit board. The system includes a primary thermally conductive plate and one or more thermally conductive discs attached to the primary plate. The one or more thermally conductive discs make intimate contact with the one or more ICs mounted to the printed circuit board such that the heat generated by the one or more ICs in operation transfers through the one or more discs and onto the plate, whereupon the heat laterally distributes across the primary plate and dissipates into the environment.
