Other than a couple faulty units there is no epidemy of overheating PS4's. I've dabbled in PC builds since the original Pentium - I'd wager I know a little more than you do. For instance, I know that organized airflow is far more important and more efficient than having a bunch of free space in your tower for no reason. Space that'll fill up with hot air that you have to vent out anyways. I'm okay with that. A lot of people do need a hole in their head. What is it with people and loud PS4 fans? I have a launch system, I play on it every single day, and it's rarely audible. Clean the vents, guys.
