I just bought and started working with a Drobo Mini as a backup solution for my office workspace. Unfortunately the fans are running without any break ever since I turned on the Drobo on Saturday. And boy - these things are loud as hell!!!
My Mac Mini sitting on my desktop right next to me is not to hear at all. The Drobo Mini sitting under my desktop is a constant source of noise hence pain in my ears. It is sitting there getting enough fresh air with enough space around it so the fans actually shouldn’t run all the time.
Oh, and the noise is nothing that comes from “vibrations” as was already answered in other threads. It seems to me that Data Robotics just uses the cheapest fans available and on top of that is not able to code a piece of software to run the fans in a proper way…
