Abstract
A cover attaches to a circuit board and has an inlet at one side for receiving forced air and plurality of openings on its top surface through which heat sinks mounted on the circuit board partially extend. Air is made to flow into the inlet and out the exhaust openings, thereby concentrating airflow in the vicinity of the circuit board's heat dissipative components.
