PS - I have some electric tools that use those same batteries, and the spares are so expensive it makes me angry that I chose that battery system :(

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.
I think this was the link...but not sure. They've covered the topic a number of times. The whole tech talk series is worth watching. They have a lot of visual demos of different design aspects of the cars. https://youtu.be/AC0eOfQl1d0
