I think the fans are temperature dependent. 4TB of disks spinning and with all 8 cores busy was like having a hair dryer running under my desk fighting with a blast of cold air from the windows on the other side. It was hard for people to hear me on the phone over all that racket. Even at -10C in winter my office (which is only lightly insulated and windows whose gaskets were blown out during a hurricane -- it is about to get new insulation and windows) stayed above 25C, and at +10C the office went to 35C and the disks were getting close to the recommended max. temp. -- George N.
