I put an electric fan on my '34 because of lack of space. It drives around town and idles in traffic at 160. That, and the location of the C/L of the waterpump in relation to the radiator. Then there's my Vette "cruiser." It has two electric fans - from the factory - and drives just fine all day long, even in bumper-to-bumper Virginia summer traffic. Not picking on any of you guys, but most of the newer cars have electric fans. I probably could have fabricated a shroud for a mechanical fan, I guess, but why bother? Whatever works, I guess.

I don't advocate it as a power saver though.
