Testing and comparing different Peltier coolers - Part 3 - TEC12706

In this video, I am testing the TEC12706 Peltier cooler. First, I measure the Imax 50%, then I map the temperature-current values across several points. Then, I determine the Tmin-Imax values (minimum temperature achieved before the Joule effect overpowering the Peltier effect). Finally, I put a thermal load on the cold side (another CPU cooler) and check the cold side temperature.
