Be sure that none of the fan blades are cracked or loose. These cracks can be hard to see, but if a blade comes loose, it is likely it will ruin your radiator. Flex fans do little good on the slow turning early engines. If you are using the later engine with the oil reservoir fan hub, I'd look there. I made a ball bearing fan hub to get rid of noise. Those hubs run on an oil film instead of bushings or bearings, and can get noisy before they seize. This message was edited by supereal on 10-21-12 @ 3:18 PM

zuktom: Assuming you have the original style fan for 1936 bolted to the front of the generator pulley, through the years, Ford had 2-blade, 4-blade and 6-blade fans to fit that application. I can tell you that a 6-blade fan is loud, and a 4-blade fan is less so. If it's just a loud blowing sound, perhaps you have a 6-blade, and might consider replacing it with a 4-blade. If it's a kind of "chirping" sound, the blades may be cracked, and as Supereal stated, they will not only punch a hole in your header tank, but the unbalanced forces can tear the generator mount off your intake manifold. Been there, done that.
