   Note ! A mistake has been made through-out the report. It was assumed that this fan had connectors for both 5 and 12 volts operation. This was wishful thinking, anyway, it was operated on +5 volts on the +12 volts input. Came to think about it. It's worn out after 6 months. I don't know if there is a connection.
