just to throw this out there i have a fan off a early to mid 90s chevy lumina, the one with the windshield that just goes for days, and it fits on the rad quite well. covers the whole thing minus anout 2-3 inches. and thats only cause thts where the hoses are. but my car never ever gets more than 1/8th the way up the gauge. way cooler than a clutch fan

From the FAQ section-
I want to install an electric fan. How well will it cool? How much power does it give me? Which fan, and how do I install it?
In short, you gain a small amount of throttle response when free-revving in neutral, and any power gained (less then 1HP) is almost immeasurable. Cooling will be no better then using the stock clutch fan since the fan is only used at idle or very low speed driving, and it is the thermostat that regulates the temperature of the engine and not the fan. There's really no compelling reason to install an electric fan unless you need the space (FMIC, 20B install, etc.) or your stock clutch fan died. Remember that the stock clutch fan freewheels when it is not needed, so it doesn't suck any power from the engine.
Lots of info on e-fans:

Top Down, Boost Up

It depends on the fan. Many e-fans pull less air the the stock fan. And there are other that will pull more, but require more juice to do it. I've also seen people using 2-speed fans, but only wiring it up for low-speed operation. That's a good way to get less airflow than stock.

Cake or Death?

A new one is $235.
The junkyard I frequent sells the Taurus fan for $15 and the Volvo relay assembly (controls a two-speed fan) for $10.
Whether or not people wire them properly is irrelevant to the intrinsic value of the fan itself.
Properly wired and using thoughtfully chosen thermoswitches provides much better fan/cooling control than the stock system was ever capable of.

Guys,
Please read the thread links I provided.
Installing a E-fan and removing the stock fan clutch system adds "Zero" HP. What it can do is free up HP that is already there. However the amount of HP that it "frees" up is not really known. The only way to find out is too run a dyno of before and after and then it would have to be under similar circumstances. Meaning that the fan clutch not engaged versus the electric fan not on, then with the fan clutch engaged, and finally with the electric fan on. This is the only way to truly know how much HP is or is not being freed up.
The overall benefit of the electric fan would be in a area with very mild climates like I am in. The only time around here that I had to turn my electric fan on in my 1st gen was when I got stuck at a traffic light for more than 4-5 minutes. Other than that I had never had to turn it on. In my case it was very beneficial because I did not have the stock fan system on and that 99% of the time I never had to use the electric fan therefore freeing up whatever HP the stock system was using. :-)
You will find more information here-

If anyone cares, I just did the Nissan Quest fan on my car and it looks OEM on top of a KOYO. Had to trim a little and took about 4 hours including making brackets. Flows very well and doesnt seem to draw that much power. Paid $60 from a junkyard.
