Computer fans play an important role in the proper functioning of desktop and gaming computers, helping to maintain optimal temperatures while performing high-performance processes.
Most computers have a small number of built-in fans, but a powerful system requires additional cooling to protect components from overheating. Each fan works differently, but all types provide a long life for the computer because they dissipate the heat generated by the components when they are in operation. Each user can find the right solution for himself – from a standard fan to special cooling elements with extremely quiet operation mode and RGB LED lighting.
Computer fans have a set maximum revolutions per minute RPM, another metric related to cooling is cubic feet per minute CFM. The higher the CFM, the more air is circulated through the fans and radiators for cooling.
There are different sizes of fans – the bigger the fan, the more air it pushes out. The 80x80mm, 120x120mm and 140x140mm fans are compatible with most standard PC cases. Many users also use smaller fans to cool motherboards and memory chips. Some fans also have a fourth pin that allows Pulse Width Modulation (PWM) control, so you can adjust the fan speed via a suitable motherboard or fan control software. There are also several models that have smart sensors – they detect if any of the components are blocked or damaged.
Another way to compare several fans is to pay attention to their noise level. Typically, noise ranges between 10dB and 36dB per dBA. Most silent computer fans have a shaft suspension that is self-lubricating without the need for external intervention. This makes them extremely durable. Other fans have very thin blades with minimal vibration, which minimizes noise and makes them quiet in operation. The speed of the fan affects the noise level, which means that if they run constantly at high speed, it will make more noise.
Many fans have different designs and lighting to create an interesting and attractive look for your computer system. Modern LED lighting does not increase the temperature in any way and does not affect the air flow. Depending on the model, PC fans have an RGB lighting system with full compatibility with ASUS® Aura, MSI® Mystic Light and ASRock® RGB. Other fans offer LED lighting in one color, which is however sufficient to create attractiveness through light.
The flow rate of computer fans helps to move air when there is no obstruction to it. Static fans are a better option when the airflow needs to pass through some elements like the CPU cooling radiator. If you want to install more fans than the motherboard can support, or you want to have an RGB fan, you need a separate fan controller.
