Review on 🧊 Pack of 5 TEC1-12705 TEC Thermoelectric Cooler Heat Sink Cooling Peltier Plate Modules 40x40mm 12V 30W by Michael Vargas

Surprisingly all the packages arrived in good condition. This was a surprise given the poor packaging and other purchases from this supplier that arrived broken and non-functional. Performance is what you would expect from a Chinese 12706. Performance is a bit slower than the US but more expensive TECs, but it's consistent between devices, and in testing I was able to get a mid-size cooler to 26 degrees Fahrenheit (ambient 67 degrees Fahrenheit) with the hot side of a liquid-cooled one Water blocks and high-efficiency 22 fins measuring 10" x 4.5" x 1.5". Everything else doesn't pump as much heat and doesn't cool the camera below about 35 degrees Fahrenheit. So good, I'd definitely recommend them buy case again.
