Thermoelectric Peltier cooler TEC-12706 (TEC or Peltier) create a temperature differential on each side. One side gets hot and the other side gets cool. Therefore they can be used to either warm something up or cool something down depending on which side you use. You can also take advantage of a temperature differential to generate electricity. This Peltier works very well as long as you remove the heat from the hot side. After turning on the device the hot side will heat quickly the cold side will cool quickly. If you do not remove the heat from the hot side (with a heat sink or other device) the Peltier will quickly reach stasis and do nothing. We recommend using an old computer CPU heatsink or other block of metal to pull heat from the hot side. We were able to use a computer power supply and CPU heatsink to make the cold side so uncomfortable we could not hold our finger to it. Note:It is imperative that a heat sink is used on the hot side of the module. Running the module without one can cause damage to this part. If it’s too hot to comfortably touch you’re in the danger zone!
