I have transferred my system over to three electric fans instead of the standard set up for a 2000 Jeep XJ, the reason I needed to do this is because the clutch fan bearing keeps breaking and you can no longer get the bracket and bearing for this. So I did not want to break the bracket. And took all the pressure off the bearing. Anyway, currently I have three electric fans installed each rated at 1200 CFM‘s., which is higher than the manufacturer CFM requirements, but I’m wondering if somebody out there is using stronger fans with higher CFM ratings.

Clutch fan bearing keeps failing? Really? How many times has it failed- in all my years I've never encountered this so I'm rather curious the cause

Everyone with a stock setup is pulling way more CFM than a triple small electric fan setup. The OE mechanical fan pulls over 5000 CFM at just 1800 RPM.

I have a Right Hand Dr., Jeep and they no longer make the bearing. I have to use a bearing from a 94 jeep that you can get and it will work however I’ve only gotten maybe a year or two out of them since doing this., so my goal here was to take off the stress on the bearing so that perhaps it will last longer.

I did happen to find a used bracket with bearing, but they want $800 for it and I am not gonna do that

When I got my 1st XJ, maybe 12 years ago now, everyone was junking their mechanical fan & forums were full of posts about fitting a 2nd electric fan. Back then, of course, all new cars had e-fans. I only got as far as removing my mechanical fan but that XJ ran perfectly fine with just the e-fan.

All this talk of cfm's all very well but truth be told, it's all academic as all new vehicles were seriously over-cooled (I did my 1st e-fan conversion to get the engine up to temp, previously the trick was not to use, say, a quart less coolant than max capacity) because they are designed to do their job in heavy traffic or mountainous terrain in tropical conditions, situations most of us will never encounter &, therefore, don't need cooling systems that can cope with them.

fwiw, my reading of OP's question was about higher than 1200 cfm e-fans, not alternative set-ups with a total of more than 3600.

there’s no way I can run with one fan! I deliver mail

Given the popularity of XJ's with rural mail carriers, I'm quite surprised there isn't a recognised conversion/set-up within the community - although I suppose locale & terrain do introduce variables.

The other issue no one mentions about all elec fan setups is power availability. I have a new stock amps autozone alternator. If my elec aux fan is on, my blower for defrost, my headlights and i am at idle my volts drop to 12 or below. If i needed wipers or rear defrost I couldn't do it. Imagine if i was running 2 or 3 aux fans...not a chance

UKXJ

If you need defrost, cooling isn't likely to be an issue & don't forget lots of small cars came out the factory with 45amp alternators & electric fans over the last 40 years, without any widely reported problems.

I am in Australia, and we have RHD of course

When that Bearing failed, I used a Ford water pump bearing I believe, but I had to carefully (and slowly) trim the front and rear shafts to length

That housing (with a used OEM bearing would be available in Australia for about $A200 and postage to USA would be about $100

So that would be about US$200 total

The bearing cost me $A80, and came from Canada (supposedly)

Luckily, in my case, I simply swapped the whole bracket out of my spare XJ, until the bearing arrived

It saved me again recently when my original 250k mile fuel pump failed (I had recently installed a new Bosch FP in my spare..I keep it going at all times!)
