PS4 gets *very* hot and internal fan is not working properly. However, this device does a good job of preventing overheating. makes a VERY BIG NOISE which means I have to turn it off, trying to unplug it over and over until it stops. It's really terrible. I cannot, in good conscience, recommend this machine to anyone. My guess is that the manufacturer saved money by using cheap components. When it works, it works well. I wish he didn't have this problem.
