It would be interesting experiment with pi4 to coat it with non conductive epoxy layers and then with heat dissipating one which has some metals in it. And put a radiator heat sink in it. Could it work just as good as ventilating cooler?
D'oh, completely forgot there already exists something better than epoxy. Do a google search for "Conformal coating". Still need to be careful with heat, though you could probably add some passive heatsinks to the cpu/etc before applying the coating.
