22 champion radiator and champion 16 inch single fan question

Just a thought because I ran into the same issue. I decided to use 2-10" fans offset in the corners. I still had overheating issues though because I didnt have enough open space for the air to move thru. You may have to cut openings on the right side of that shroud to allow more air to move thru the radiator.

Hoping you dont have to but just wanted to make you aware that its a possibility.
