This article describes a forced convection, downward flow, positive pressure cooling system for a floor standing personal computer (PC). It utilizes the power supply enclosure as an air entry vacuum chamber, flow across a vertical planar opposing the natural convection boundary layer and a plenum design with entry chamber and exhaust chamber to create equalized card column air flow through eight feature cards. (Image Omitted) The primary benefit of a properly designed cooling system is reliability. Longer life and low failure rate is directly related to the operating temperatures of a PC system's components. Another factor causing reduced life is particulate build-up (dust), which results in component temperature rise.
