Abstract: A heat sink assembly includes plural thermally conductive hair fins configured to be thermally coupled with a component to be cooled. The hair fins are elongated along a first direction and separated from each other by gaps along different second and third directions. The hair fins are configured to receive heat from the component to be cooled and to transfer the heat to cooling air disposed between the hair fins in order to cool the component.
