Drobo 5D Clicking/Ticking noise (after moving house)

Hello all,

I recently moved property and today, I powered my 5D up again after a couple of weeks of no use, and immediately there is a loud clicking/ticking sound.

The sound happens when my hard drives ARE installed and NOT installed.

Would this be down to the fan bearings failing and perhaps during the move, something has happened? I can’t upload either a .m4a or .wav file here, unfortunately!!
