Brand new WD_BLACK D10 Game Drive running hot

I have just bought a WD_BLACK D10 Game Drive to use as a backup for my NAS unit. It is running at 50 degrees Centigrade at idle and the cooling fan is not on. Is this normal or is the fan faulty? My other external Seagate drive which is fanless runs at 40 degrees Centigrade when data is transferring to it.
