PSU making loud buzzing/humming sound

My PSU (BeQuiet! Dark Power Pro 1000 Watt) has recently started making this annoying 'buzzing' noise. It started off intermittently but is now making this noise constantly. It's quite noticeable even when the case is closed, and is really annoying.

I've uploaded a video of the noise:

Any idea what's causing this, and how to stop it? (And should I be concerned?)

Loud buzzing is very annoyed. If I were you, I would RMA it for replacement.

It sounds like vibration to me. If it is then it's probably something to do with the fan. Is it loose or touching anything?

Have had it a year and a half so not sure it would still be eligible for RMA.

I'll remove and re-seat it and report back.

The BeQuiet 1000w P10 Dark Power Pro has a 5 year warranty so you will be ok if it needs a RMA.
