Peltier cooling with a 4xTEC12706 block and water cooling

In this video I will show you a bit more complex Peltier cooling system (thermoelectric cooler). I assembled a CPU/GPU water cooling system and used it to cool the hot side of a Peltier-based cooling block which consists of 4x TEC12706-type thermoelectric cooler. I also added a temperature sensor which measures the temperature of the water at the outlet of the radiator.

I connected 2 Peltiers together in parallel connection, so they draw ~12 A at ~12 V. So, I made 2x2 Peltiers and I drive them with my DIY dual-channel power supply. If you build my power supply, you can also track the power consumption and the output voltage/current.
