Specification: Get ice cold in minutes or heat to boiling by simply reversing the polarity, used for numerous applications from CPU coolers to alternate power sources, or even for your own custom car drink warmer/cooler. Since they consist primarily of semiconductor material sandwiched between ceramic plates and have no moving parts These devices must be used in conjunction with a heat sink to avoid burned Each device is full inspected and tested Fitted with 6-inch insulated leads Installation Cooling piece is very simple to install and use. Before installation, to find a dry cell, connected to the two leads of the cooler, obviously cold you can feel at one end and the other end of fever, remember that the polarity of the lead and determine a good cooler cold and hot end. If you want to get a bigger system Ling, it is recommended that two cooling mode, with two stack up with the above, a grim absorption following a fever, the experiments prove two refrigeration effect is much better than the single-stage, the condition can choose three, of course, have a large power supply support. Package included: 1x TEC1-12706 Thermometric Cooler
