ABSTRACT:
A computer system utilizes a heat sink which optimizes the benefits of both linear airflow and turbulent airflow within the computer housing. The heat sink has rows of metal fingers extending from a metal sheet. A fan generates linear airflow within the housing. The heat sink is attached to a heat producing element such that the rows of fingers are placed parallel to the direction of airflow in the housing. The fingers are spaced apart within a single row to generate turbulence in the airflow, and the rows are spaced apart to prevent the turbulence of one row from interfering with the turbulence of an adjacent row.
