Why is it important to keep a computer cool?

Computers use electric impulses to function. The harder a computer works, the more impulses are sent through. Energy creates heat and impulses slow down as a computer climbs in temperature. This can cause impulses to not arrive correctly which can lead to corruption or crash. The most common methods of keeping a computer cool are fans, heat sinks and liquid cooling.


Fans are generally the cheapest and most common way of cooling a computer. They are setup in a way that air flows through the computer in one direction, drawing in cool air, whilst simultaneously extracting heat. With the advancement of technology and the energy used to run certain systems, fans may not be enough to cover the load of heat expelled. Fans can still be used in the conjunction with other cooling elements.

Heat Sinks

Heat sinks require airflow thus need to be used in conjunction with fans. Primarily used on the CPU (central processing unit) heat sinks extract heat using a thermal conductor. The heat is dispersed through the heat sinks ‘fins’ and blown/withdrawn using the fans airflow.

Liquid Cooling

Computer liquid cooling typically works the same as a cars cooling system. The purpose of a liquid cooling system is to extract heat created by energy. The radiator dissipates heat caused by the energy used from the system’s hardware. This cooling system works in a loop and requires a few components to operate. These cooling systems are generally more expensive but target advanced setups that expel such heat.

What sort of cooling should you be using?

Minimum level cooling systems are required according to a computers energy consumption. Low level systems that are used typically for general home use and office administration should only require fans and a heat sink. Advanced computer setups used for gaming, streaming and other applications that incur a heavier load consequently requiring better airflow or liquid cooling.
