Mine is actually a PS4 Pro, which was running hot (judging by the color-change stands I used to raise it up a bit). I opened it, cleaned the fan, replaced the thermal paste, and dusted everything. Now it doesn’t heat up, but bright scenes send the fan spinning up like a turbojet! It goes down in volume only during loading screens (black, in Skyrim). Some suggestions towards figuring out how to cool it QUIETLY would be helpful.
