A system for cooling an electronic device comprising a heat sink including a channel having an inlet and an outlet, with the channel coupled to an airflow generation system that generates airflow between the inlet and outlet. Heat is removed from an electronic device by decreasing the cross-sectional area of the channel to provide a throttle at a location adjacent to where the channel traverses the electronic device. A plurality of throttles may be formed in the channel, each for cooling a separate electronic device. An airflow control valve is operably connected to the heat sink for controlling the amount of airflow through the heat sink. A device controller connected to the airflow control valve and the air generation system adjusts the airflow control valve according to temperature measurements collected from the electronic device and controls the operation of the air generation system.
