At one point Packard offered an optional fan for the 110 and 120. (Service bulletins or shop manual) They warned that the optional fan would be noisier than the standard fan and would pull more power. I think the '36 and '37 cars had an improved fan as standard equipment. One problem with a higher capacity fan is that it will require more power at highway speeds, and that will require a tighter fan belt, which the water pump bushings will not like. My car has an electric fan attached in front of the radiator and operated with a manual switch. It helps cooling at low speeds, but it draws a lot of amps. I suspect it may actually block airflow somewhat at higher road speeds. It would be an advantage in heavy traffic or in a parade in hot weather, but the substantial current draw taxes the stock generator. A good clutch fan would be nice, but there isn't room for such a thing. The '36 & '37 hood louvers look very restrictive to me, and the engine compartment is not nearly as well ventilated as most. The inner fender panels on my car are too nice to cut up, but I'd think a custom pair of fender panels made much like the 1938 ones would substantially improve cooling. The '36 & '37 inner fender panels lack any concession to ventilation.
