I ordered a Drobo FS last week and was a little irritated about the noise of the fan. It is continuously spinning at the same level, noise is comparable to a Mac Pro in idle mode.
Drobo support told me that this is not normal and asked for the diagnostic data. Result: “Temperature sensor is not working, device has to be exchanged”
Now I’m sitting here in front of the next Drobo FS and it is as noisy as the first one. Could anyone here give me a hint how the fan noise should be under normal conditions?
