Overheating at highway and hard acceleration

I have been experiencing overheating 230-240 temps at highway speeds. I read the forum and replaced everything that I could find that would be causing the issue. Fan, radiator (went moshimoto), radiator tubes, thermostat (replaced with ripp), water pump, coolant, air filter, sc oil, engine oil.

I am currently at a loss as I am still experiencing the same overheating. I never had over heating issues until one day driving back home from work … now nothing seems to fix it. Jeep runs fine and isn’t running any codes (other than aftermarket fan now). My intake temperature is normal, all other vitals are fine. This wasn’t a slow growing overheating issue but instead just one day started.

there is no murkiness in the oil (eliminating head gasket issue). Before having a shop tear apart my engine I wanted to see if there were any other suggestions.

16 rubi Jeep has 45k miles, ripp supercharged, 5.13 gears.
 
Was your fan LOUD AS HELL like an airplane engine? That is what mine sounds like. Mechanic ignored it but I am wondering if mine is a fan issue as well. I am having the same problem. 2017 JKU
I changed out thermostat and purged the radiator. I let it purge for close to 20 min seeing air bubbles for at least 15 min. Is working good right now. Good luck
