Cpu fans and heatsinks help ensure that your pc works efficiently at all times.
Cpu heat sink.
Both a heat sink and a radiator require airflow and therefore both have fans built in.
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.
All modern computers rely on some form of heat exchanger with higher end models using cpu heat sinks.
Other components that may have a heat sink include the north bridge south bridge and memory.
It may also shorten the life of your cpu or cause immediate damage.
These important components are not just for computers.
It is important that such machines stay as cool as possible.
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.
They always have some cooling usually a fan.
Large heat sinks help any machine that generates heat as a byproduct such as a car or refrigerator.
