Then you may propeller the fan blades into the radiator...

Has it been established that TJ's have an overheating problem? I readily acknowledge that you are in an environment that makes it more challenging then mine, but a few posts on JF does not make an epidemic. Think about how many TJs there are in the world functioning with stock setup and no problem (mine included). JF is a small fraction of the world of TJ owners and people generally only create threads if they have a problem. Would be pretty boring if all the people with no problems started threads to tell us that. The negative selection of what threads are started leads to a perception of too many "common" problems.

I know of a few problematic TJ's with overheating issues and by and large, no amount of money, gadgets, high dollar external coolers, and very expensive radiators have solved the problem to better than another stock system.
I've related the story of my wife's rig too many times, but after the CSF fiasco and a bit of research and not too much at that, I swapped back in the stock 1 row from the dealer, found a good friend willing to trade me a 7 blade fan and HD clutch and it's cooling is rock solid at any speed on the freeway with the AC on full blast. And, it is an auto with a very small cooler for the radiator in the grill area.
The thermometer on the mirror display was 107°F earlier this week and it's been consistently over 104.

I switched to a Taurus 2-speed electric fan last winter and now that the summer heat is here I am putting the stock clutch fan back on because the electric fan just doesn't cool as well during slow trail riding and extended highway speeds during the summer here in Georgia heat.
My Taurus 2-speed electric fan conversion (complete with wire harness, factory relays, adj thermostat, 3-way guarded switch and indicator lights) is for sale here:

You can get the TSB fan clutch, but not the 7 blade fan. If you find a source for the 7 blade fan, please let me know?...

Do you understand why there is a big shround on a belt driven fan? Its because the fan is so far away from the rad you would get no air pulled throw the rad. When you mount a electric fan you mount it to the rad not the engine. So you dont need a big shroud. I think one of the reasons there is so many people who say electric fans are bad is because they dont understand them.

Within reason, the depth of the fan shroud will not change the amount of air through the radiator provided it is contructed properly.
I think you need a better understanding of how air flows, but you could always learn some by removing the shroud from your electric and report back.
