While true, it sure helps offset the temperature climbing if you have the fans blowing air from a lower temperature and at least helping offset how long it will get to that temperature, but that I could see as more of a bandaid if the temps are climbing regardless. But what do you have to lose by lowering fan turn-on temperature?
OEM thermostat is also hotter than 180 degrees Fahrenheit.

AC condenser is clean and fins are straight car is low miles and I meticulously clean it.
The weather has cooled down a lot now so I'm not sure if i will be able to get a log of the car getting hot sitting in traffic but ill try to replicate it.

Data point: Driving today with AC suburban type driving just a few stop lights and stop signs. Coolant temp was pretty stable at 200.
I popped the hood and confirmed at 200 with the AC on both fans are indeed spinning the proper way and working. To me this seems like the radiator and fans just arent able to shed the heat enough and in hotter weather or more sitting in place coolant temps will continue to rise.

I wouldn't be opposed to it. There are some hard to seal gaps between the shroud and radiator too near the inlet and outlet so I'm sure that takes a hit as they just suck air through those holes and not the core.
Not seeing much as to how other people mount direct to the radiator. Do people prefer mounts like this https://www.holley.com/products/cool...parts/30130013 or to make/buy something else?
Edit- If I do pull the rad I will also be doing the reroute at the same time since I'll have already lost all my coolant. Kind of tough choice between FM and Supermiata. FM has the benefit of bypassing flow to the turbo which is nice but then I loose my coolant hardlines and have to run silicone.
