Step 1: How It's Done..
Connect the modules in series.
Put some heatsink paste on the cold side.
Put them on the water pot as the picture.
Glue them with some thermal silicone (NOT ON THE SURFACE) and wait until it dries.
Put a sensor in the center for the temperature.
Put some heatsink paste on the hot side.
Now put some thermal silicone on the spaces between the modules and put the whole thing on the other pot (hot side pot / aluminum sheet).
Now you can test it with a voltmeter and its temperature sensor!
