A heat pipe transfers the heat to a location remote from the electronic component. A heat sink is mounted to the circuit board at the distant location. The heat sink has at least one groove formed on an underside thereof. The heat sink is mounted so that is overlies the heat pipe and the heat pipe is introduced into the groove, thereby securing the heat pipe between the heat sink and the circuit board.
