What is a computer fan and how does it work?

Any computer can suffer from severe damage if it is not properly protected by a fan. Therefore, we advise you to make sure whether your computer has a fan built-in—and if not, for you to buy one. These components not only cool your PC but also help to clean it by removing any dust that builds up inside it. And most importantly, using a fan can extend the overall life of your computer. Before you settle for a specific computer fan, you may be interested in learning more about these accessories and forming an opinion. This will allow you to make a more informed decision and purchase the model that best suits your computer use. As you can imagine, you won’t need the same model if you’re an avid gamer, a graphic designer, or if you simply use it for basic tasks.

Shopping Criteria for Computer Fans

Every computer fan will offer its own specific features and knowing what these are is a great way to help you make the right decision. These characteristics often have very complex descriptions, which can render your task much more complicated. As it is difficult to test a computer fan first before buying it, we will introduce you to some of the most important aspects to keep in mind when selecting the best computer fan for your needs.

  • Size
  • Noise
  • Airflow
  • Connections
  • Quality


The size of the computer fan is indicated in millimeters, with the most common measurements being 80 mm, 120 mm, and 140 mm. Please keep in mind that a larger fan size will make it easier to move air at the same speed, which will, in turn, lead to your device being quieter.

Description: Fans found in today’s computer towers often come with 3-pin or 4-pin motherboard connectors.

However, the most important factor is that you purchase a model that fits the space available inside your laptop or computer tower. Certain devices may have limitations regarding this aspect, so you are advised to carefully check the manufacturer’s specifications, compare it to your computer, and test whether the size would fit to avoid any unpleasant surprise. Once you’ve done this, remember to pick the largest fan possible for the reasons mentioned above.


Your computer fan’s noise can become particularly annoying if you use your computer every day. Luckily for you, there are ways to limit this. First of all, you should know that the greater the rotation speed of the blades, the more noise the device will generate. As you can imagine, the product’s quality will also play a role in the overall noise level. The noise is measured in decibels (dB), and you are encouraged to purchase a fan whose operation does not exceed 30 dB. While you want a fan with low noise levels, make sure that this doesn’t affect its performance.

Did you know that today’s computer fans are also chosen based on their aesthetic values as they provide LED lighting in different colors and modes?


This function allows you to know how much air is being propelled into your laptop or PC tower. This value is measured in CFM (cubic feet per minute) or ft3/min. The higher the airflow is, the more air your fan is moving into your device. A CFM of 50 is the minimum value at which a fan is considered to be efficient.

This flow refers to the temperature, pressure, and humidity conditions of your computer. Fans that integrate this functionality the best at renewing the air inside the device at high speeds without generating too many obstacles regardless of whether it is located in the front or the back of the tower.

Fans found in today’s computer towers often come with three- or four-pin motherboard connectors. A three-pin fan will generally operate at normal speed, with the connectors being regulated by the sensors located on the motherboard. In four-pin models, these connectors can be controlled using software. It is again up to you to form an opinion about the aspect of connections and compare the possible products based on that.

The integration of this additional pin makes it easier for the motherboard to automatically control the fan’s speed according to the temperature of your device. In that regard, it also helps prevent damages to the computer circuit or the malfunction of the fan when you use your computer for prolonged periods.


Specific criteria such as the noise level are naturally key, but you should also evaluate the overall quality of the product. While assessing this efficiency can be quite tricky, and it is not possible to test the fan’s performance first. Each manufacturer ascribes an average life (in hours) to each computer fan. This value can help you better judge its quality and compare the available models.

While many current models can operate for more time and suffer less wear, keep in mind that reducing the fan’s speed will increase its useful life. The manufacturing brand itself can serve as a guide to assess the reliability of the product, while certain details such as the type of plastic used will also give you an idea of its quality.

Where is the fan located in a computer tower?

Buying the best model on the market isn’t enough to get the most out of your computer. You should also know how to install it correctly so that it can ventilate all the necessary components. Computers integrate several fans distributed as follows.

One is located in the power supply, a second in the graphics card, and a third in the central processing unit (CPU). Remember that creating an adequate vent flow is even more important than the number of fans itself.

How can I prevent my PC from overheating?

There are several tested principles that you can apply to prevent your computer from reaching above-normal temperature levels. That way, its internal components are better protected, and you can extend their useful life. You should also note that your PC can reach higher processing speeds and run more smoothly at low temperatures.

Avoid obstructing the air vent of your fans, and keep it away from surfaces that tend to heat up more easily. You should also perform regular checks to make sure that they work properly. If you decide to purchase a quiet model, keep in mind that the fact that it makes more noise may indicate a malfunction.

Should I choose a high-static pressure or high-airflow fan?

Two main types of fans are available to you, and the model you choose will strongly depend on how you use your computer. Therefore, it is important to form an opinion about that aspect. On the one hand, high-static pressure fans generally feature very large blades with joints located between them. This results in a smaller amount of ventilated air propelled at higher speeds.

High-airflow fans, on the other hand, renew the air inside the device as quickly as possible. These models tend to be installed in computer towers to prevent the hot air from being trapped inside and compromising the device’s overall performance. This type of fan is ideal for people looking primarily for efficiency and speed. It is advised that you check the requirements for the product and compare them based on these aspects to find the best one for you.

Why does my CPU need cooling?

The central processing unit (CPU) is the brain of your computer and the number-one component to keep in mind when you’re looking for maximum performance from your device. This element tests the operating system, gives instructions to other components, and receives the signals and actions provided by the various programs you’re using.

In spite of being the very core of your computer, it tends to overheat because of its small size and its exposure to such a wide array of operations and tasks. This is why it is so essential to have a fan specifically dedicated to the cooling of the CPU. It has been tested that this will increase the durability and maximum performance of your device.

Which software can control my fan’s speed?

Indicated in revolutions per minute (RPM), the speed generated by your fan can generally be managed using various software tools. They will give you maximum control over your device and prevent any overheating that could damage its proper operation. The software CPU SpeedFan gives you real-time access to your microprocessor and hard disk’s temperature, the fan speed, and the CPU load.

The software NoteBook FanControl is a cross-platform fan control service for laptops. Its configuration system is versatile and adaptable to various notebook models. The software EasyTune 5 improves the performance of Windows-based systems. The software TPFan Control manages the fan through the I/O port with the integrated controller. The software Argus Monitor controls your CPU’s temperature, which you can view numerically and graphically. By comparing and testing the different features you will find the one with the best usability for you.
