▷ How to choose the right fan for your pc

Are you thinking of mounting a new fan inside your PC? Finding the right fan requires researching its features and the details to consider. In the market we can find a large number of fans with different sizes, different bearing technologies, speeds and many more details that complicate the selection process. In this guide we explain what you should take into account to get the right fan and mount it on your PC.

How to choose the right fan for your PC needs

In fact, selecting a suitable fan is not difficult, as long as you are a good judge of your own needs and product specifications. In general, we basically choose two types of fans, those focused on a high static pressure, and those focused on offering a large air flow. These characteristics depend fundamentally on the design of the fan blades.

The front panel fan generally requires a type of high static pressure fan to allow it to pass through the front of the chassis, which will inject a constant stream of cold air into the chassis. The angle of inclination of the fan blades and the curvature of the blade are two factors that influence the pressure value of a fan.

High static pressure fans usually have very large blades and very close to each other, this results in the passage of less air, but at a very high speed. In contrast, fans focused on offering a large air flow have more blades, but these are smaller and are widely separated from each other. These fans allow the passage of a large amount of air, although it does so at a lower speed.

Example of a high air flow fan:

Example of a high static pressure fan:

These high static pressure fans are also used in heatsinks as they offer increased performance by pushing air with great force against the aluminum radiator of heatsinks. At the rear of the chassis, it is normally equipped with a heat extraction fan, making wind volume more important than pressure. At the same time, the heat inside the chassis can be discharged more quickly to the outside of the chassis with the use of a fan that moves a large amount of air.

Most important characteristics of fans

Below we review the most important characteristics of fans, these are air flow, static pressure, generated noise, bearings and lighting, which is so fashionable today.

Air Flow: The air flow of a fan measures the amount of air that the fan passes through its blades per unit of time. The flow is measured in CFM or m3 / h, the higher the value, the greater the amount of air that the fan moves. A CFM of 50 is the minimum number to make a fan efficient.

Static pressure: represents the force with which the fan pushes air through its blades. The static pressure is measured in mmH2O, the higher this value the greater the pressure with which the fan pushes the air. Ideally, opt for a fan that exceeds 2 mmH2O, or at least comes very close to this value.

Noise: no user likes their PC to be very noisy, so it is important to choose fans that are as quiet as possible. Noise is measured in decibels (dBa) and we should opt for a model that does not exceed 30 dBa. The noise generated by the fan increases as its speed of rotation increases, although the values ​​of CFM and mmH2O also increase, which is why we must seek the best possible compromise between silence and performance.

Bearings: these are the bearings that are inside the fan and allow its rotation, these wear out with use, so it is important that it be of high quality. Today the best fans have hydraulic or magnetic levitation bearings.

Lighting: It is something that looks very nice, but does not add anything to the performance of the fan. Lighting can be an interesting aesthetic addition, but you should never put it above quality and performance, it is better to opt for a fan with high values ​​of CFM and mmH2O but without lights.
