In a typical embodiment an electronic circuit board of any type or size is comprised of electronic components producing heat during operation. High thermal conductivity moldable pads applied to both sides of the electronic circuit board form a conductive pathway to transport heat away from electronic circuits and components. A two piece rigid heat sink having thin rigid conductive fins on its top base is coupled together forming a cavity into which the computer board/conductive pad assembly fits, thereby forming a second conductive pathway for heat transport away from board features. The thin rigid conductive fins collectively form yet a third conductive pathway for heat transport from the solid base of the two piece rigid heat sink. Exposure of the thin rigid conductive fins to cooler surrounding air provides convective transfer of heat from the fins to ambient air.
