How We Test To Find out The Best PC Fans
The rotation speed refers to the motor and the blades. They make up the structure of the fans. The testing data expressed in RPM (rotations per minute). It is the first parameter to take into consideration to buy the best PC fans.
This value is closely linked to two other parameters, the size of the fan and the noise generated. It shows in dBA (decibels) on the measurement scale that demonstrates the sensitivity of the human ear to low frequencies. dBA is a personal parameter in terms of noise perception.
The higher the RPM value, the higher the noise produced. The ability to move air volume will be significantly greater. The smaller fans have a high rotation speed compared to the same size, while the larger fans can guarantee less noise and greater airflow.
The best PC fans, regardless of the noise produced, limit vibrations as much as possible. As for the size parameter, it is essential to consider the space available inside your case. And finally, check its compatibility for a correct installation.
Static Pressure Fans Vs. Airflow Fans
The airflow fans come with the CFM value (Cubic Feet per Minute). It is a formula derived from fluid dynamics. Here, we use precisely to measure the maximum volume of air that a fan can move. The value in CFM reported in the manufacturer’s specifications refers to the maximum rotation speed of the fan in question.
Usually, an airflow fan can maintain high airflow and generate more noise. So, you can look for the best compromise between these two parameters.
Static Pressure Fans
The static pressure comes with the millimeters of water. It belongs to the units of measurement relating to pressure.
Every single fan has a performance curve inherent to the airflow that it delivers in front of resistant back pressure, or an obstacle. The greater the resistance expressed by the obstacle to the generated airflow, the lower the constant flow that the fan can maintain.
It is a measure that refers to the potential energy of the airflow that we were talking about before in the particular cross-section of a duct.
Factors to Consider When Choosing The Best PC Case Fans
Meter is the value that most affects the size of a PC fan. There are several on the market and clearly, the amount of air moved depends on this. Our advice is to choose a fan of the right size for your needs. Do not exaggerate too much with the diameter and test the amount of space available in your PC case.
For RPM, we mean the maximum rotation speed of the fan or the revolutions per minute of the same. The larger fans can produce good airflow even at 1000/1500 RPM, while the smaller ones need to work at 3000 RPM to produce sufficient airflow.
The noise level of a PC fan is evaluated in decibels (dB) and is often indicated by the manufacturer in the technical specifications of each product. No sane person would like to have noisy fans on their PC. So, our advice is to aim for products that can have good efficiency even at low speeds to ensure the silence of the system.
The connector of a PC fan is nothing more than the cable that we supply it with power. It must be connected directly to the motherboard. You must be careful to verify the type of connection that the latter supports. There are several types of connectors on the market that differ according to the number of pins and size.
Airflow is another important feature for PC fans. Each model generates a flow measured in CFM (Cubic Feet per Minute). It is a figure that in a nutshell represents the volume of air that the fan. Here, the rule of proportionality between CFM and dB applies as a fan that can produce a large flow of air will also produce a greater noise.
Are 120mm or 140mm fans better?
120mm fans are the model we recommend the most. They are especially compatible with almost as many houses and heat-sinks. They can move full-bodied air flows. For this reason, they can have better results than 140mm even at low speed and with silence.

A 140mm fan is a performing model that can operate even at low speeds and produce little noise thanks to its large dimensions. But, because of its size, it is important to check precisely whether the space available in the case allows its dimension.
What speed should my PC fans be?
RPM can normally vary within a defined range. It can usually go from a minimum of 300 RPM to a maximum of 2000 RPM, at least in the most popular models on the market.
What are PC fans called?
There are two types of PC fans, one called “case fan” and the other called “CPU fan (cooler)”. Both are available for cooling the inside of a personal computer. Although there are physical differences in arrangement and number of cords, they are products for the same purpose.
The vast majority of users rely only on the fans included in their case or on the proprietary ones included with the heat-sink. So, the best PC fans will surely satisfy you.
Noctua NF-P12 is our best choice as it offers all the best features of a PC fan such as non-vibration, high airflows, excellent durability, and a long lifespan. If you have a limited budget, Scythe Kaze Flex is worth considering.
