An LED light display cabinet include a fan mounted in the interior of a cabinet housing. The fan draws air into the housing via one or more outside air inlets, and exhausts it to atmosphere via a chamber. A chamber is formed adjacent the rear door of cabinet and includes an opening in communication with the fan outlet and includes second air inlets, and baffles. The chamber permits outside air to be drawn into the chamber to cool the interior of the cabinet and exhausted out the rear of the cabinet. If the fan does not operate, air can still be drawn through the chamber for cabinet cooling.
