Review on DAOKI TEC1 12706 Heatsink Thermoelectric Cooling: Efficient Cooling Solution by Chris Chincuanco

Arrived on time. All units are in good condition. Seems like a good value. Now check everything with an ohmmeter to make sure the circuit is complete. If the circuit is ok, the device should be ok. Thus, there is no need to connect to a power source and damage the part. To learn more, google the concept of the Peltier principle to understand how it works. It's actually VERY simple, because everything in nature strives for balance, yin/yang. Action reaction. The power turns on, one side heats up and the other cools down. Reversing polarity and swapping sides from hot to cold etc. DO NOT DO THIS WITHOUT A HEAT SINK ON THE HOT SIDE AS THE HEAT GENERATED MAY MELT THE SOLDER OR PRINTED CIRCUIT BOARD INSIDE THE CERAMIC BOARD. THE CHAIN WILL NOT FILL ANY MORE AND THE BLOCK WILL BE DESTROYED.
