Stupid question time:

I just went to look at this car for my wife. When I popped the hood I noticed that there is no cooling fan attached directly to the motor, like on my M104 equipped C280. Further, the only fan visible was a single electric fan on the back (engine) side of the radiator. My C280 has two auxilliary electric fans on the front (bumper) side of the radiator. I accustomed to seeing more fans, so this has me a little concerned.

Is this single electric fan set up correct for the 3.2L V6? Or is this particular car missing some fans somewhere?
