With the wide applications of semiconductor cooling, more and more DIY enthusiasts are interested in it. It's a question that how to make refrigerating capacity to a more great extent in water cooling applications. This DIY kit could be just to your taste to solve this problem.Note:1. The conduction cool module can frost when the temperature is under 25 C.2. TEC112706: one side with words is the refrigeration side, the other side is heat dissipation side.3. Must install heat sink or watercooled radiator on the heat dissipation side; otherwise will burn the Peltier.4. The DC power is not included in this kit, please prepare it by yourself.Specifications:Semiconductor Chilling Plate: TEC112706Size: 40 * 40 * 3.75mmInternal Resistance: 2.1~2.4 Omega;Max.
