Corsair One making fan(?) noise

Does anyone know what's up and how I can fix it?

Hey @apotos

It's a little hard to tell from the recording.
My suspicion would be either that the fan bearings are the issue - or that the fan is clipping a cable.

Try taking off the top grill by firmly pushing the button on the back of the C1 (preferably whilst Idle, and not for terribly long)

Does isolating the fan from the rest of the chassis stop the noise?
Does the noise then come directly from the fan itself - or from further inside the system?
