Abstract

A fan driven heat sink assembly which includes a fan assembly mounted on a heat sink for mounting on a microprocessor unit. The heat sink has a solid flat base, a plurality of spaced cooling fins and a housing which is fixed to the base. The cooling fins are fixed to the base and extend from one flat surface of the base to a top wall of the housing. The top wall of the housing has an aperture which is aligned with an outlet opening of the fan assembly. The fins extend from a first end opening at one end of the housing to a second end opening at the opposite end of the housing. Airflow from the fan assembly extends from the opening in the top wall of the housing along the spaces between the fins and out through both end openings of the housing.
