Laptops often employ an internal system fan that's connected to the Central Processing Unit and Graphics Processing Unit heat sink. The CPU and GPU are the two biggest heat producing components inside the laptop: they can produce enough heat without cooling to break themselves. Faster computer hardware tends to produce more heat than slower computer hardware, but both tend to break around the same temperature range. The internal fan keeps the CPU and GPU from damaging themselves.
