One thing you learn about high end performance cars is just the sheer amount of heat they spew at all times. From everywhere. Part of it is they have far more than a single radiator. Once you start crossing $100K USD a fair number of cars start getting to 3-5 heat exchangers (even NA cars!), and it climbs from there.

Road going performance cars have fans first to help get things up to temperature for emissions, and after that, for when you’re at low speeds or stationary. So you don’t overheat (or catch fire) when you’re stuck in traffic after having the car at high load.

Race cars tend to not have any fans near their primary heat exchangers. You get more airflow without fan blades creating impedance, and you just rely on the airflow at speed to do all the work.
