Two different issues - one is the radiator cooling fan, and one the injector 
cooling fan.  My 1982 80CD had the former - you could park the car and be 
inside the house before it did an imitation of a Jumbo jet landing.  This was 
a carburretor engine - no injectors to cool.  The 1988 ur-quattro has no 
afterrun on this fan, but does have an injector cooling fan.  It's loud, 
perhaps, but it ain't anything _LIKE_ as loud as the 80CD's Jumbo imitation. If 
you parked in the street, the 80CD would frighten passers by.
