When I replace radiators, the AC condenser also get cleared out with compressed air from the back, blowing forward. I am amazed at all the sand and bugs that come out that must have been causing airflow restrictions.
Not a solution for you but it's one of the many contributing factors.

I removed the condenser from my last jeep for better airflow and installed metal window screen behind the grill to catch bugs. Never again, it became a sweat box in this harsh sun..
That was long before I was a forum member and knew about a stronger fan clutch.

My 99 DD, on the other hand, has ice cold AC.

Just had a thought, does your radiator have an internal transmission cooler or do you have an external cooler plumbed in?
Having a transmission cooler plumbed in could help. Not by much but it could.
I still think the E-fans are causing most of the drama.

Did your rig have the same heat issue before the e-fans?
And since the 3 row was installed, did the issue start or get worse?
The 4.0 block often has crud in the coolong passages and the passages on a 3row are very small and get clogged by it.
