Hmm, this seems more like a specific solution for just this setup. I've put my Pi 3 in a transparant enclosure and heatsinks on both chips.(Bought it as a kit)

Hmm, this seems more like a specific solution for just this setup. I've put my Pi 3 in a transparant enclosure and heatsinks on both chips.(Bought it as a kit) After a few days i noticed it overheats a little when it's really active. While i was researching more silent cooling options i noticed that the bottom part of the enclosure was way hotter than the top part. I glued four big string beads under the enclosure. It now looks like the smallest transparant table in the world. Problem solved.
