All modern computers rely on some form of heat exchanger with higher end models using cpu heat sinks.
Cpu heat sink.
They always have some cooling usually a fan.
Cpu fans and heatsinks help ensure that your pc works efficiently at all times.
When you use heavy applications such as video games and video editing software the cpu can produce excess heat which may cause your computer to freeze.

The heat sink has a thermal conductor that carries heat away from the cpu into fins that provide a large surface area for the heat to dissipate throughout the rest of the computer thus cooling both the heat sink and processor.
A heat sink also commonly spelled heatsink is a passive heat exchanger that transfers the heat generated by an electronic or a mechanical device to a fluid medium often air or a liquid coolant where it is dissipated away from the device thereby allowing regulation of the device s temperature.
Other components that may have a heat sink include the north bridge south bridge and memory.
These important components are not just for computers.
Both a heat sink and a radiator require airflow and therefore both have fans built in.
It may also shorten the life of your cpu or cause immediate damage.
