You should never need the main fans on at 80mph , Never had a issue until i installed the larger whipple heat exchanger. Since then 4 years ago i had force my main fans to 100% every summer . Once air temps drop back to the 80s i switch back over to ECM controlling the fans , takes about 5 min to swap plugs around. Fans on with a/c maxed and 120 degrees out is a ton of load on Alternator, yes my temps stay in check with Fans at 100% . But from a reliability point now if i have a fan failure , i'm screwed in the desert with 120deg out , and no matter how fast i go i will overheat . I'm reverting back to smaller exchanger with two 9 inch SPAL fans . Plus the Ron Davis radiator so i can drive 50+ mph with out the main fans on and temps stay in check.
This is a Arizona environment situation . You will not have issues in northern climates.
