Factory aux fan?

Anybody know if any e46s came from the factory with the electric aux fan, or is it strictly a retrofit?

Thanks. I've seen the DIY thread, guess I didn't pay enough attention to catch the bit about manual trans cars. Makes sense, without the need to hook up to a trans cooler. I was trying to determine just how deep into a cooling system refresh the previous owner had gotten. The hoses, expansion tank, and thermostat are all clearly new, and it has a metal ECS WP pulley, so I'm going to assume its a new pump as well. I couldn't believe that the previous owner had been anal enough to swap the fan, so this makes more sense.

Manuals came with a single electric fan, autos have an auxiliary electric fan behind the front bumper, in addition to the mechanical fan.
