what are you guys running for electric fans? trying to figure out if it would be better to run two smaller fans or one big fan.

Two smaller fans = lower amp draw on startup.

For my needs two fans, to cover the top since that is where the heat is.....for those rare days when we are near 100 degrees and everything is saturated with heat, it would be nice to have a third fan that is switchable separately covering the bottom when your stuck in traffic for hours.

are your two fans adaquate for what you need? would you like the 3rd for piece of mind or out of need? are you running the stock radiator? what size fans did you go with?

really? so if i had an 18" fan and two 9" fans the draw on startup would be less on the two? i figured it would be the other way around.

Don't take my word for it, check out the ratings on electric fans from various manufacturers. DeRale for example.

2 fans are better than 1 for redundancy.

it works out better with the cfm too. im gonna run 2. thanks for the replies guys.

Junior,

Stock Sl6 radiator that comes in a 74 Swinger. If I had a choice I would go with the V8 (340) radiator for extra cooling on 100 degree days.
I run two 10" fans and a 195 degree switch screwed into the EGR port on the radiator.
System runs great and is barely on in the Puget Sound climate. Not unless I get stuck in freeway traffic for several hours or it's one of those 95 to 100 degree days...
The spoiler under the car forces enough air through the radiator that fans rarely come on. It is a pretty nice system.

The two small fans draw about 6 to 8 amps. I still run the stock alternator but did the SL6 Dan dual 10 gauge wiring mod. I do have the 120 amp 94 Dakota alternator rebuilt and ready to go on. Just never needed it with the two small fans. They push enough air that when you open the drivers side door you can feel it on your feet when you step out!

I have a large aluminum radiator and use one 18 inch fan.

I run one offset pusher fan at the moment. Early A's don't have a lot of room between the radiator and the water pump pulley bolts. With the new, larger radiator, the previous puller fan didn't clear even with significant offset.

I ran a large 16" fan for about 5 years till I got smart......bottom blew cold air all the time, top blew hot.

So put the two small fans at the top where the heat is a reduce your amp draw as well......kill two birds with one stone! It sure is a lot less wear and tear (strain) on the electrical system.

i ordered two 10" fans, themostat control for them and im going to wire in a relay. should be good to go. thanks for all the replies.

I installed a dual 10" fan setup, with a small block triple core radiator. The fans easily kept my engine at the proper temperature, they were quiet and efficient....but, because they turned on infrequently, the engine compartment got really hot, heat soak was an issue for me. I wrapped my downpipes with header tape, ceramic coated the exhaust manifolds, installed a heat shield, still too much heat build up in traffic. A third fan/more cooling for the rest of the engine bay would have been needed, so I simply went back to my SS flex fan and it stays cool in the engine bay.

Do you guys running electric fans not have hotter engine bay issues? Maybe my more efficient radiator was too much, i.e. kept my fans from running more and that's what I needed?

thanks,

Brian

These controllers can be set to be always on at least 10%, keeping the engine bay from becoming an oven. Expensive but high quality. The sensor is superior to just about anything out there.
