Abstract
A heat sink comprises a plurality of fins that may be positioned in a plurality of orientations relative to a heat-generating electronic component to which the heat sink is thermally coupled. A controller may be used to detect an elevated processor temperature and to activate a drive member to automatically adjust the orientation of fins on the heat sink. The fins may be moved and aligned with an air flow made over the heat sink. The adjustable-fin heat sink affords added flexibility in arranging a processor or other heat-generating electronic component on a circuit board. The orientation or position of the heat sink fins may also be automatically changed in response to a change in the air flow direction as manifested by a rise in the temperature of the heat sink or the heat-generating member.
