usually when reading about cars im told that this next generation model has vents that allow for better cooling of the engine which leads to better performance, im wondering why cooling some machinery allows it to preform better and if this is a universal thing or if some things run better when hot

1. Simple diffusion: Particles move across their concentration gradient. If you want less heat in the engine, you should remove the heat surrounding the engine so the new air around it can absorb more heat from the engine.
2. Engines use internal combustion, if they get too hot, they’ll expand / seize up because it’s all metal inside rubbing together. You don’t want them to melt.
3. Oil lubricates these parts to keep them from experiencing high friction and to help cool them a little, the hotter your oil gets the sooner it will need changed.
