Review on ❄️ Efficient Cooling Solutions with the Thermoelectric Cooler Refrigeration Cooling TEC1 12706 by Russ Mashlan

Reliable workmanship. Works without too much noise. This element is set by default to cool the heatsink and use water circulation to remove heat from the hot side of the Peltier chip. The radiator was literally covered in ice, and the air was noticeably colder than the surrounding area. Instead I reversed the polarity and chilled the water. Unfortunately, the heat sink and fan are not sufficient to dissipate the heat generated. This item could not even dissipate heat from the very small submersible pump I used for the test. I strongly recommend not attempting to cool water with this item. The best cooling was achieved by turning off the pump and literally cooling the water down to ambient temperature. I'll do another test with just 1 chip and see if it gives better results. Update: Even using only 1 chip results in an irresistible amount of heat for this heatsink. This does not work with water cooling.
