Peltier cooler-based air cooler

In this video I tried a new gadget. This gadget is a heat sink “channel” that has three TEC12706 Peltier coolers on two of its sides and has a fan on one of its end which pushes air through the heat sink channel. This is sort of an air cooler with a nominal cooling performance of 420 W. However, the real cooling performance is much closer to 200 W in “normal conditions”. In this test, I want to see what kind of outlet temperature can be sustained with different configurations.
