Does anyone know if it possible to disable a single fan from within the XOS? I have one of eight fans on the x450 whistling like crazy and need to quite the thing down. The switch is located at one of our Fire Stations and is located near the sleeping quarters which is the main reason I need to shut this thing up. All fans currently show as "Operational at 1000 RPMS" but haven't found a way to adjust these speeds. Kevin,
