My van has a hopped up engine. It does that with the air on. Electric fan and a bigger aluminum racing radiator. Solved everything but 100-110 degrees driving like a madman on the freeway. Then straight into stop and go traffic it comes up. Used to peg. Now it barely above half on the gauge.
Running the air introduces heat into the radiator. Condenser on a air conditioner gets hot.
Removing the shroud brought the temp on the freeway down. A full point on the gauge.
Electric fan made the air work at idle sitting and kept it from overheating when sitting idling with the air on.
It was fairly straight at that point. Then I got the radiator.
