Abstract: A redundant cooling system with abatement of noise from cooling fans being used primarily in computer equipment and other boxes housing electronic equipment. Typically either the computer system or box housing electronic components has two parallel side panels, a front panel, and a back panel upon which cooling fans are mounted to draw air across various electronic components and through the box for heat dissipation. The cooling system includes an airflow grille attached to one end of a laminar flow duct and two adjacent cooling fans mounted to the other end of a laminar flow it duct which includes a Venturi opening on the top panel of the laminar flow duct to facilitate laminar flow through the laminar flow duct at a distance before the cooling fans and at a distance after the cooling fans.
