360 running hot…very hot

At idle after start up takes about 10 mins to reach 190 then just keeps going. The shroud is slightly bigger than the 16 inch fan inside it. I'm starting to think this is an airflow issue. Stop and go traffic it goes to 230+
16" is a really small diameter for a fan. Can you get us a static picture of it? Like not turning a thousand miles an hour? lol
