1. A system for regulating the temperature of a heating or cooling device without adjusting the input power, comprising:

  • a heating or cooling device comprising a cold region, a hot region, and an input power, there being a temperature difference between the cold region and the hot region; and

    a controller comprising a heat transfer pathway in thermal contact with at least a portion of the cold region and at least a portion of the hot region, the heat transfer pathway configured to create a path for heat exchange between the portion of contacted hot region and the portion of contacted cold region, whereby the heat transfer pathway is controlled to regulate the temperature of one of the regions, resulting in a controlled region and a non-controlled region, and wherein the heat transfer pathway comprises a fluid circuit, said fluid circuit comprising a channel with a fluid therethrough, an adjustable valve for controlling the path of the fluid in the fluid circuit, wherein the adjustable valve is electrically actuated, comprises a thermistor, or is actuated with a solenoid.
