Power brick making a loud kinda grinding noise?

What kind of noise does it make? Is it buzzing or grinding noise? The noise is coming from the little internal fan and it's been know that some faulty units make this noise.

The power brick on my Xbox 360 Slim used to make a loud grinding noise when I had it from new. To stop the noise I used to pick up the brick and give it a few hard taps with the palm of my hand. Once I did that it didn't make any noise for the duration of
that play session until then next time the machine was switched on again.

Strangely enough, I never had the brick replaced and it now it no longer makes any noise. If you are concerned though and you can't get the brick be quite you should take up a repair request with Microsoft Support to get it replaced.

Is the console itself making the loud noises or is it the power brick that is doing it?

What did it sound like? Was it a wirring or a screeching noise? If it's the former, I may be in the same boat as you.

The loud noise you hear is a fan in the power brick i had the same problem i had to replace the power brick because it went red when the light is.

Could it be updates? Its happening to me on a Monday morning. And my Xbox keeps making loud grinding noises.
