How to Choose a Quite Pc Fans?

Where Should Pc Fans Be Placed in The Case?

To get the most out of your computer, it is not enough to buy the best fan, and you also need to know how to install it correctly. There are many videos showing how to position it the right way.

In concrete terms, the fans should be positioned like this: one near the power supply, another near the graphics card, and the third near the CPU.

What Rules Must Be Followed to Prevent the Computer from Overheating?

If you take into account some basic rules, you will prevent your computer from reaching too high temperatures, keeping the internal devices intact, and prolonging its useful life. Furthermore, if the temperature remains low, the PC will have a more top processing speed and will function better.

Mainly, it would help if you took care not to block the air outlet from the fans, keeping them away from surfaces that heat up quickly and checking their correct operation. If you choose a silent PC fan, but then you hear it make noise, it probably isn’t working as it should.

How to Choose Between a High Static Pressure and A High Airflow Fan?

Mainly, there are these two types of PC fans. Depending on the function you want it to perform, you will have to choose one or another. On the one hand, the high static pressure fans have wider and joined blades. Therefore they let less air pass but at more top speed.

On the other hand, the high airflow fans renew the air circulating inside the PC as much as possible, with little difficulty. They are installed in the case to prevent hot air from concentrating inside and impairing the performance of the computer. This type of fan is ideal for those looking for something useful and fast.

What Is the Cpu and Why Is It Essential that It Does Not Overheat?

To get the maximum performance from a computer, one should not overlook the importance of the CPU or central processing unit, which is the real brain of the machine. The CPU controls the operating system, instructs other components, and receives signals and program actions.

It is a fundamental part of the PC, which due to its small size and a large number of operations it performs, heats up quickly. For this reason, if you decide to install fans, make sure one is aimed at cooling the CPU. Thus the computer will have a longer useful life and will function better.

Purchase Criteria

When buying a PC fan, you have to consider many features that vary from one model to another. Often, the descriptions are elaborate, and it isn’t easy to know which is the best option to consider, but in this section, we will tell you about some fundamental criteria that will help you choose more consciously.

  • Size
  • Noise
  • Air flux
  • Connections
  • Quality


PC fan sizes are measured in millimeters, and the most common sizes are 80mm, 120mm, and 140mm. Consider that the bigger the fan, the easier it will be to move the air at the same speed, and the device will also be quieter.

The most important thing, however, is to choose a fan suitable for your computer case as some can be more limited in terms of compatibility. Always read the manufacturer’s specifications to avoid nasty surprises. However, when choosing, always opt for more massive fans, as we have already told you.


The noise generated can be very annoying in the long run, although, fortunately, there are some ways to make it less noticeable. First, consider that the higher the speed at which the blades turn, the greater the noise produced. Second, product quality also influences this aspect.

Fortunately, there are some models of PC fans whose speed can be adjusted to reduce noise. Noise is measured in decibels, and a good model shouldn’t exceed 30 dB. Although it is always better to choose a silent PC fan, you need to make sure that this does not affect its performance.

Air Flux

The airflow is measured in CFM or m3 / h. The higher the value of this number, the greater the amount of air moved by the fans. Typically, 50 CFM is the minimum value that makes a PC fan efficient.

Airflow is related to temperature, pressure, and humidity conditions. The function of the airflow fans is to renew the air inside the computer at high speed, without creating obstacles and passing it to the front or rear of the case.


Today’s desktop computer fans are equipped with three or 4-pin motherboard connectors. In general, a 3-pin fan runs at average speed, and the connectors are regulated through the sensors on the motherboard. Those four can be controlled through software.

The fact that some systems have this built-in feature facilitates the automatic control by the motherboard of the fan speed as a function of the temperature, a useful aspect to avoid damaging the computer circuits and guarantee the correct functioning of the fan, even if used for a long time.


In addition to considering the noise or cooling of the fan, you must also find the quality of the appliance as a whole. Although it is difficult to evaluate it effectively, you need to think about the average life in hours that the manufacturer assigns to the product.

If the speed is reduced, the useful life of the fan increases, although many modern products are more durable and do not wear out quickly, even the brand of the product can be indicative of reliability, and some details such as the type of plastic are fundamental to get an idea of ​​the quality of the fan.
