With the wide applications of semiconductor refrigeration, more and more DIY enthusiasts are interested in it. Looking to boost cooling capacity in your water cooling applications? This DIY kit might be exactly what you need! Features: Uses a TEC112706 semiconductor cooling plate for reliable performance. Fully sealed structure isolates moisture in the air. Higher reliability compared to others. Includes TEC112706 semiconductor cooler, 2 fans, and other accessories for easy installation. Fantastic DIY kit for electronic enthusiasts in semiconductor cooling applications. Note: The cooling module may frost when the temperature is below 25°C. TEC112706, the side with words is the cooling side, the other side is the heat dissipation side. You must install a heat sink or water-cooled radiator on the heat dissipation side, otherwise the Peltier element will burn. The DC power supply is not included in this kit, please prepare it yourself. Specifications: Semiconductor cooling plate: TEC112706. Size: 40 * 40 * 3.75mm. Internal resistance: 2.1-2.4 Max.
