VW/Audi's have used a system with a timer that allows the fan to run after
the vehicle is shut off, but only for a certain period of time so as to not
run down the battery. As far as a vehicle only cooling the radiator when
shut off, bear in mind that early cars cooled only by convection, I'd bet
that when the vehicle is shut off and the radiator fan is on, some convection
is induced. Seems unlikely that at least a couple manufacturers spent time
designing systems to run on after the car was off without cause.
