PS5 Slim (PlayStation 5 Slim) NMB fan noise

The PS5 Slim NMB fan makes a distinct droning noise when a game is loaded. At the start of the video I start a game (from cold) and you can hear the fan spin up. The mixing in this video is off a bit because the iPhone microphones interpret the drone as background noise and try to remove it. If you listen carefully you can also hear coil whine and airflow noises in this video but those are are inaudible in reality. I’ve since had this console replaced. The replacement also has an NMB fan, which makes a similar amount of noise but it’s not as pure a tone so it’s much easier to ignore.
