Is the fan suppose to be operating while in all standby mode? I've been hearing mixed feedback on this with many saying that it should be completely off when is "deep sleep" mode.
To make sure, I disconnected my PS4 from the internet, unplugged the USB, closed any applications/games, and then placed it on standby overnight. In the morning, I can still hear the fan operating very quietly when I am very close to the system. In addition, although the fan on my PS4 seems to be within normal noise levels, it does make a slight raggedy sound such as you would hear from a loose fan.
