A networking hardware system includes a housing; a board located in the housing and comprising a plurality of components; a liquid cooled heat exchanger; and one or more fans disposed near the liquid cooled heat exchanger and configured to provide cool airflow from the liquid cooled heat exchanger to any of the plurality of components. The housing can be substantially sealed from an external environment and includes no air intake thereon, removing a need for higher powered fans and for air filtering for dust. The housing can include a faceplate with no air intake thereon, providing increased density for ports on the faceplate.
