the pics show just a part of the setup , i tested with a heat sink on the hot side , 2 plates alloy 5mm 200*200 , that was supposed to be on the top of the case , and yes outside, but before i cut a hole in the case i tested and realized that the heat sink outside need to be a lot bigger and yes with the foil moving (forced airflow) it might work but when you stop, the top gets very hot and finish by heating everything, need a fan as well i guess, so the all thing will take too much place
pull 130W so i guess i needed 300w of heat dispersion on top of the case…
