Run electric fans all the time?

That’s not quite right. The hotter you can run an engine, the more power it will make, to a degree. Meaning if it gets too hot, bad things can/will happen.

Look at drag racing for a moment. Top Fuel, the longer they sit at the light, the more power they make due to the heat. That’s why, sometimes, they blow off the tires(smoke show). The game is played at the staging, ya hear about it all the time.
