Review on 🌬️ Efficient Cooling Solution: Northbear Thermoelectric Peltier Refrigeration Heatsink by Dragan Nelson

later Works, sort of. Claimed temperature drop of 20. Outside the environment. It was 72 degrees in my room. It was installed in a sealed wine cabinet. This only lowers the temperature to 66 degrees. The hot side was 86 degrees. Thus, the temperature gradient across the entire block is 20 degrees. I expected 20 degrees to come from the surroundings, not the hot side.
