I've also not had any problems with battery run down, but it also has a good charging system...

Flex-a-lite has them. It comes with the 294 and 295 dual fan kits or you can purchase it by itself.
The Mark 8 is a good fan to use if you're on a budget, but it does not cover the entire radiator. I've been running the 295s for years and no problems. They're dual 13.5" pullers and they're mounted in a shroud that covers the entire radiator. The VSC ramps the fans speed up slowly so it doesn't tax the electrical system. It can run a 2 speeds, 60% or 100%, to maintain the tempreture. It also has an input to where the fans will turn on when the AC compressor is running and also with a manual on switch if so desired.
The 295s can move up to 4600 cfm and the 294's can move as much as 6000.

I run Flex-a-lite fans on both my trucks, both of which are controlled by a variable speed controller with a temp probe pushed in the radiator fins for temp control. My gasser and my diesel. I haven't gotten to drive my F-150 long distance yet, but it doesn't seem to have any cooling issues. I drive my diesel every day and the fans on it use the same controller and motors as my 294 universals I put on my F-150 and it has been working great on my diesel.
The main reason I went to e-fans was not for mileage or power. I don't think there is much to be had as far as that goes, but I can say I noticed a slight difference in response on my diesel after the switch. I switched to e-fans on my F-150 so I can turn the fans off when I get in some water when I'm wheeling and I switched to them on my diesel basically b/c everyone said e-fans couldn't keep it cool, so I'm out to prove otherwise. LOL

i went with the FK-85 here:
Constant Temperature Controllers and Accessories
it's a little pricey yes.but there are advantages.less draw on the alt,without the high amp turn on spikes,and much more constant temps than with the relay type i had first.which is better for the engines head gaskets because your not drastically changing the temps up/down so quickly.i also noticed the fans just work at keeping it cooler easier than with the relays too.it was worth every penny.i couldn't be happier with the thing.i dunno how things work there now,but it was just Brain i think who builds them as he goes,likely a side job.so order in advance if you want one.it can take a while.

I didn't see much about A/C in this thread. You really want the fans running when the A/C is on or you will only get minimal cooling at a stoplight.
That Felx-a-lite variable speed controller has an input from the A/C to run the fans when the compressor is running. It can also be done with another relay as shown in some of the diagrams.

I've got that with my Flex-a-light. Been thinking of putting a switch inline so I can disconnect it in the winter. Comes on with the defrost but I'm thinking it's not really necessary.

i run a single 16in e-fan w/a spal vary control unit capable of running dual fans if the need occured w/ a/c over ride. the single fan moves 2300 cfm and is mounted in a sheet metal housing w/ 12 louvers to help air flow when the fan is not running. i was thinking of using a hole saw and making holes instead of louvers but, the louvers look nice and i also used a orbital sander on the sheet metal to give it a satin look when the fan is mounted and it came out pretty well when all was said and done. my setup to me runs good and have no problems at all. i was also thinking of changing the fan and running 2, 12in fans just to see how cool it would be when running.

if you leave the fans running after shut down it only really cools the coolant in the radiator and through convection cools the motor down a little faster not enough to make a difference. wireing two fans so that if one fails the other can keep going is a good fail safe being the odds of both fans failing at the same time is pretty dang rare. I had a s10 with a 406 in it and the duel tarus fans kept it super cool and if it did start to get a little warm i had a toggle in the cab to kick fans to high could watch the temp gauge drop the worked so good. something to think on is surface area that the fans are pulling from? if you zip tie the fans to the radiator it will work and can get the job done but if you go get a cooky sheet that close to the dimension of radiator the fans pull air through the whole radiator which cools things evan better. Ive cooled big block motors and hot rat motors with the tarus fans Ill stand by them before any aftermarket fan Plus the have two speed rates so if you were to get fancy you could have 4 different levels of cooling power
ok ok i went a little evil with the last idea but you got to admit that would be cool
