) will pull more air than a factory non-electric fan. Real problem is, no one (that has come forth anyways) knows what the stock fans move CFM-wise, so we don't have the data to say authoritatively what CFM you'd need from an electric to match stock. We DO know based on what people have done thus far, that the Windstar fans cool just about every engine out there.
In any case, they are better than mechanical fans in this case, as you can shut them off. Mechanical fan blades will pull forward, potentially taking your radiator out.Neither is true.
A large enough electric cooling fan (you didn't say how big) will pull more air than a factory non-electric fan.

I don't think that the windstar fans move as much air as the stock fan, but they're on the higher end (for airflow) for junkyard fans and they are really easy to find.
As aforementioned, one advantage to electric fans is that you can shut them off when you're going through water/mud.
Lots of people that swap to electric fans have cooling problems (including those with windstar fans) so that's something to consider. K5's do have good cooling systems to begin with (in general) and bigger radiators are very easy to fit.
I paid $52 shipped off Evil-bay.Snail mailed the payment and got it in less than 2 weeks.But thats unusal....because its a company I think.But I saw them from $30 up to $150.If you can just check every day until you find one.i think i know i payed under 30 for my windstars, if you can, get the weatherproof connectors that plug into the fan motors, just cut them off 6" or so from the plug.
it will make life easier
