I never saw that claim before, fans using up to 45 horsepower. EEK
One of the "tricks" we performed in the Jurassic era was to replace the factory spacer & flex fan with a fan clutch & fixed blade fan from a more expensive model, like a Lincoln. It was supposed to save 10 to 20 bhp, but the engine also ran much quieter. It was a nice upgrade for a street motor.
Since electric fans are more readily available today, with more choices to select from, it seems they would be the way to go nowadays.
