True, the Peltier junctions consume power. At maximum power, each device'* total heat dissipation would be in the neighborhood of 130W. If, however, that heat could be effectively transferred away from the device, such as with a liquid cooling system or very large heat sink, then the cold side of the device would become and remain sufficiently cold to provide a performance boost.
