Cooling Fan

The cooling fan is an essential computer component that keeps computers from overheating. One of the main causes of computer failure and component deterioration is heat. The cooling fan helps to keep your computer parts cool, while providing adequate air flow through your computer casing. When purchasing a cooling fan, you will find that there are many different features and types of cooling fan. This article seeks to shed some light on the cooling fan and its different functions.

Many parts of the computer make use of a computer fan. One of the most recognisable types of cooling fan is the case mounted cooling fan. Most cases make use of at least two fans. One cooling fan blows air into the case, while the other expels hot air from the case. Computer processors usually have one dedicated cooling fan that continuously blows onto the processor and heatsink. Most video cards also make use of a cooling fan used specifically to cool the graphics processor, which heats up when using graphic intensive software. One large cooling fan is used inside power supplies to blow onto the power supply components, while expelling air from the case.

One of the main concerns in using a cooling fan is the noise they produce. Since the cooling fan constantly spins at high speeds, they produce vibrations that make noise. Many high-end cooling fan manufacturers make "silent" fans that operate at optimal levels while reducing noise. There are many different computer fan sizes depending on your needs and the component to which they are fitted. Some of the normal sizes include 120mm, 92mm, or 80mm fans.
