Review on DAOKI TEC1 12706 Heatsink Thermoelectric Cooling: Efficient Cooling Solution by Omar Svagera

These are very simple peltier cold plates. No instructions, hot and cold sides aren't even labeled. The printed side is considered cold. However, I wanted to be sure, so I quickly cycled the power on and off, then checked which side is hot or cold. (This happens quickly, so unless you have an efficient heatsink on the hot side, it will burn out quickly.) I use a 300 x 140mm aluminum heatsink, cooled by ten 25mm fans. (Five on each end.) A thin sheet of aluminum foil is taped to the heatsink to allow air to flow in quickly from one end and out the other. This works well when both cold plates are used at the same time. I plan to add two more panels, all four separate, and then see if there is enough cooling. My original goal was to cool a small pet fountain because in the summer it got so hot that slime formed on the surfaces inside. 24 hours. But after moving to a cooler place, this is no longer a problem, even with an ambient temperature of 25 °C. Evaporative cooling keeps the water so cool that slime doesn't form quickly. However, I'm still experimenting with coolers as I'm a curious person. (Science is cool - even for old retirees like me!) Here are the fans and heatsink I use. If you try something like this yourself, make sure the power supply and thermal paste are correct. =B07FFLHW29&psc=1https://www.amazon.com/gp/product/B07KS36L66/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1
