Weird - the machine seems rather quiet to me, but it's in a separate
room with the laser printers and no one actually working there.

I don't know how to measure noise, unfortunately. I have another
Gen8 at my wife's office for their not-for-profit organisation.
Quiet as a mouse with FreeNAS 11. This time two also very quiet
(most of the time) computer based office desks in that room.

My machine here at my office:

So, temperature sensor working, too. Or are you referring to the
*HDD* temperature? I never put disks to sleep in servers ...
