Features: Adopt 2pcs Tec1-12706 semiconductor chilling plate, good quality for use. Complete sealed structure, isolating the moisture in the air. Higher reliability than others. Include 2*tec1-12706, 2*conduction module, 1*water block, 2*fans, 2*thermal grease, 1*base board and a pack of screws. Lightweight and mini in size, easy to install. Great DIY kit for electronic enthusiasts in semiconductor cooling applications. Note: 1. The conduction cool module can frost when the temperature is under -25C. 2. Tec1-12706: one side with words is the refrigeration side, the other side is heat dissipation side. 3. Must install heat sink or water-cooled 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.
