XBOX ONE MAKES WEIRD NOISE

I did an exchange recently via MS and got a brand new unit with a manufacturing date that was 3 weeks old. May want to try MS.

I purchased the Madden bundle and the first one I had made a buzzing noise too. It was VERY annoying and even made the noise when just sitting on the home page. I returned it and the second one is almost dead silent. Definitely return it if yours is making
a buzzing noise...

It's a constant noise not one that has breaks in it. A low pitched buzzing sound. Only goes away when a game is loaded.

The fan theory does make sense. But this does not sound like a noise a fan would make. It's more of a electrical buzz or whine if that makes any sense. Kind of like a old computer would sound when it was writing stuff on to the hard drive but just a bit
more intense and high pitched.

I was reading up on some forums and it seems that a lot of people have had this same issue specifically with kinect less versions of xbox one. It's supposedly the gpu making the noise when it's at a low power state and it seems many Xbox ones are affected.

I second the fan theory. When the system is somewhat idle, the fans most likely slow down, allowing you to hear the noise of the issue. When you game, the fans would be going full blast as that is a more intense usage of the XB1 and the sound may go away.

Some notes:

• You could wait a few days and see if it goes away. I had this issue on a prior XB1 and it left and came back a few times but never last more that a little while.
  
• If it persists, contact: https://myservice.xbox.com unfortunately they can only do a hardware exchange.
  

Good luck, keep us posted!
