Most electric fans draw more current than a generator can provide. Often cooling problems have less to do with the fan, and more likely to the radiator condition. Limed interior and fins that have broken contact with the tubes are at fault. Most old Ford systems are more than adequate when in good condition. My '47 made it through the hottest summer on record without any problems. When I bought it years ago it wouldn't make it around the block before pegging the temp gauge. A new radiator fixed it, and 25 years later, all is well.
