Noisy Synology

My Synology makes a funny noise when it's doing absolutely nothing. I'm not sure what's causing it, or how to stop it, but it goes away on its own for a few minutes at a time, only to return soo after

Exactly same problem. Going to try and add some velcro to dampen the vibration noise. Video coming soon!

It´s vibrations from the hard drives. I resolved this by sticking a folded piece of paper under one of the drives.

call synology to respire or change the fan yourself.

I've got a noise like this all the time. Did you ever figure out what it was?
