Abstract: A circuit layout includes two or more high performance processing nodes that are cooled by a cooling fan. The cooling fan resides in a cooling fan assembly that relies on principles of aerodynamics to maximize airflow. The cooling fan assembly is coupled to the opposite side of a backplane to which the circuit layout is mounted. The backplane includes large ventilation holes to permit the cooling fan to induce significantly more airflow across the circuit layout than possible with conventional designs. At least one advantage of the approaches discussed herein is circuit layouts can be constructed to meet the competing objectives of high node performance and high node density. Accordingly, data centers can be built that offer high performance computing without requiring a significant increase in physical real estate.
