Change of plan: Next up I ordered this 140mm to exhaust hose 3d printed adapter. Let's see if I can move the miner's heat to the next room or maybe come up with something to move heat around the whole apartment.
Next up, building a case/cover to make it more beautiful somehow.
Anyways, It's whisper silent now.
