tec1-12706 12704 12705 12708 12709 12710 12712 12715 cooling piece

the working condition of the cooling piece is that one side is cooled and the other side is heated. when working, the heating surface must be well dissipated. it is forbidden to be powered on for more than 2 seconds without heat dissipation, causing overheating and burning. the buyer is responsible for it!

install the radiator must be coated with thermally conductive silicone grease.

there are literal cold noodles and non-literal noodles are hot noodles.

the power given to foreign trade customers cannot reach the original one

please order the original ones from other stores with high requirements. please do not compare the quality with the original ones. you get what you pay for. please do not buy those with high power!

for batch customers, please buy samples first,

return is not accepted
