Watch the video to see how it works.

Be carful DO NOT go above 120 degrees celsius when direct heating the module (without a metal sheet) even if it says 150 degrees.

Any questions just comment down :)

Step 1: Put Them Together..

Put the heatsink paste on the metal sheet and then put the TEG module and glue its sides to the metal. aluminum is the best sheet for this case.

Put some heatsink paste on the other face (the cold face with writing) and put the aluminum cooler and glue it.

attach the motor in the way you like.

wire the cables after putting some heat resistance tubes and make sure of the polarity so the fan should cool the cooler as it runs.

That's it!
