Re: Electrical fan or not?
I'd use a good ole clutch fan, fluid not thermal, releases above certain rpms, not temp. I'm using one with my AFCO alum. radiator and no shroud, it doesnt get hot and I don't have to worry about running the battery down. I don't see any real advantage of running an electric fan unless you're using an electric water pump too, otherwise leaving the fan on just cools the radiator, not the water in the block. Or you could get a Moroso water pump drive, runs fan and waterpump, as long as you don't forget it and let it run the battery down.
