May want to do a super cooling system flush also would not hurt to spray out the radiator to clean off dirt and bugs so that you can get better air flow across the radiator fins.

Did not mention that because I thought you would have done that already but yes replace thermostat.
I checked both fans are working and coolant is pumping to the radiator
