Why does a processor, for computers, get so hot? How doesn’t it just melt? How does a fan and a heatsink work so well?
There's an enormous amount of work happening in a tiny amount of space. Under load, CPUs use (relatively) huge amounts of electricity, which generates heat. The heat in the CPU can be controlled with a fan because, while it's very hot, it's also a very tiny area.
The Short Answer
There's an enormous amount of work happening in a tiny amount of space. Under load, CPUs use (relatively) huge amounts of electricity, which generates heat. The heat in the CPU can be controlled with a fan because, while it's very hot, it's also a very tiny area. So the total amount of heat-energy that needs to be removed is quite small. Heat sinks have a huge surface area (unlike the CPU) and are made of material that conducts heat very well. So the heat-energy is moved from a tiny space to a huge space (surface area is what counts), and then quickly moved away with a fan.
