ABSTRACT:
An add-on heat sink for increasing the thermal efficiency of an existing heat sink comprises a support base, a first plurality of fins extending from the support base for dissipating heat and a second plurality of spaced fins extending from the support base that are arranged to intermesh with the fins of the existing heat sink and to form an interference fit therewith, whereby the add-on heat sink can be removably attached to the existing heat sink.
