Rattling Sound in ThunderBolt Display 2014

[A.Chakery]

Hello,

It is less than a year that I purchased my ThunderBold Display.

Today when I turned on my MacMini I heard a rattling sound from my TB display...

When I move the display I can hear a sign change in the sound which indicates that it is a mechanical sound.

Would you please tell if it is a bad sign or something ?

Probably a defective fan, you'll have to bring it in an apple store to get it fixed.

How did you solve your problem? I have one similar myself: https://forums.macrumors.com/threads/humming-sound-som-thunderbolt-display.1948848/
