Has anyone tried one of those USB desktop fans, would this run off the USB port on the Dialog (they only need power from USB port)? Might offend fan-less sensibilities but they can be very quiet and will just move air across the casing. Cheap as well, I have a 'Daffodil' which is whisper quiet and has a speed dial on the top. I don't own a Dialog but thought this might help, or be worth trying.
