Best case fans

By equipping your PC case and its components with adequate airflow, you will need the best PC case fan. There are a host of different chassis fans to choose from, all of which offer various sizes, noise levels, and airflow. If you have high-end hardware (like large GPUs and powerful CPUs) in your case, on average this hardware tends to generate more heat, which is even more important. If these components are not cooled properly, your PC can increase the ambient temperature of the room and stop working efficiently. Additionally, the additional heat can even shorten the life of some equipment. This is why we like to use only the best fans.

So, if you are looking for the best 80mm, 120mm, 140mm or even 200mm chassis fan, don't worry, we have already provided the service for you. Below is a list of the best chassis fans currently available for 2021. All fans have passed performance, efficiency, noise level and airflow tests.

With this in mind, let's take a look at the top competitors.

When buying the best PC case fans, you should consider the following factors to ensure that they are not only suitable for your system, but also kept cool enough.

So let’s skip to the most important things to consider when looking at the best fans of 2021.

The first thing to consider is whether it is better to buy a high static pressure fan or a high air flow fan. This is determined by the actual shape of the fan blades. Yes, that is correct. You can get the exact same fan shape and model, but the fan blades are different.

No need to pass spec sheet

Behind the fan. For example, if your case has enough open space, these fans should provide more efficient airflow for your case. The

static pressure fan distributes air more evenly. This means that they are not as strong in a straight line, but they can work well when there are obstacles like components and radiators.

So what is CFM? Well, the fan airflow is measured in CFM or cubic feet per minute. This determines how much air the fan can circulate in one minute.

Generally speaking, the higher the CFM level, the better. However, static pressure can use less CFM more effectively when it comes to hardware obstacles. The ideal CFM for the

PC will vary from case to case, because many factors must be considered. Factors such as chassis size, design, CPU heat output, the type of CPU cooler you have, the GPU fan (either outdoor or blower type), and the number of chassis fans that can install. ventilator? Well, this is very basic: they move more air.

If you are not sure what size will fit your box, just check your box manual. You can also visit the manufacturer's website to verify the dimensions and specifications of your case. If all other methods fail, just take the tape measure and measure the fan inside the box.

The following are some of the more common fan sizes and the distance between their screw holes:

Fan speed is measured in RPM (revolutions per minute). The higher the RPM, the more air will enter the system. RPM has a direct effect on the noise level of the fan, because the faster it spins, the more noise it produces.

This can also affect the size of the fan you want. Although you can use a small fan quickly, it may be louder. Therefore, you can use a larger fan at a slower speed.

To get the correct RPM for your configuration, simply use third-party software such as SpeedFan to set the fan to full speed, and then reduce the speed by 25% until the fan is not too high and the temperature is acceptable.

Most fans currently use three basic types of bearings. They are as follows:

This type of bearing is the cheapest and is expected to last about 40,000 hours at 60°C (140°F). The

fan speed is designed for low maintenance and low operating noise. It is recommended to install this type of fans vertically, which is said to be quieter.

However, it should be noted that despite low operating noise, they tend to fail without warning. The

double ball bearing is more expensive than sleeve bearings, but has a longer service life; operates at 60 ° C (140 ° F) for up to 60,000 to 75,000 hours.

is different from slide bearings, they can be installed in any position, and the sound is louder. That is why it is not recommended for home use, but it is very suitable for server farms.

These are high quality bearings. They typically have the longest lifespan, with run times of 100,000 to 300,000 hours at 60 ° C (140 ° F).

and double ball bearings, can be installed in any position. They also have the lowest noise level of the three and are suitable for server and home use, although they are mostly used for home use because they are a bit expensive.

Fan noise is measured in decibels (dBA). Weighted decibels are one way that we can measure the volume of sound in the human ear. Almost all chassis fan manufacturers include the fan noise level. Some of the factors that cause

fan noise include:

Generally, its range is between 10dBA and 36dBA. In any case, for obvious reasons, you'll want a chassis fan with the least noise. The following is the relationship between the volume of these noises compared to everyday sounds: The

has three types of fan power connectors:

Operating the 3-pin connector at low voltage may cause problems or stop operating the fan . Therefore, when doing this, make sure you know exactly what you are doing. The

connector type will affect compatibility, so please check the motherboard connector type before purchasing. The

chassis fan can be customized to enhance the appearance of the PC through the color circle or RGB lighting. For fans, we tend to prioritize features because they help extend the life of the system.

When installing fans in your case, you need to choose whether each fan is an intake fan or an exhaust fan.

Ideally, you want to make sure that there is at least one intake and one exhaust, but don't worry too much about the ratio. Some terms to be familiar with

are:

Obviously you need a neutral air pressure. A good way to do this correctly is to measure the total CFM of all intake fans and the CFM of all exhaust fans.

If the intake CFM is higher, a positive air pressure is obtained, and if the exhaust air is higher, a negative air pressure is obtained. The same amount of CFM means it has approximately neutral air pressure. Please note that if the fan is blocked, its maximum CFM cannot be compensated.

It is also worth noting that the fan placement may be difficult to put down. Therefore, it is best to pay attention to the dusty places. If you think it is causing a problem, you can adjust the fan position accordingly.

If you are not sure whether your fan is in or out, then the next section

Which case fan is best for your computer? You should review the following:

Understand your needs and wants. Assess your needs in advance and prioritize what your PC really needs. Are you having trouble in a specific area or are you looking for a suitable chassis fan to take precautions?

Be sure to check the type of connector on your PC. Before purchasing, be sure to check the available connectors on the motherboard to avoid compatibility issues.

measures the size. Check your case manual or website for the exact size and number of fans supported.

Will noise be a problem? If you need a quiet chassis fan, please consider choosing a fan with the least noise. On the other hand, if noise is not a problem, you may find that the noise is not so quiet, but it still works well at a lower cost.

How do you want to control your fan? If you want to dynamically control the fan speed through third-party software, please purchase a fan with a 4-pin connector. Otherwise, most ordinary users will do a good job with a 3-pin fan.

Cooler Master Silencio FP 120 PWM is indeed worthy of the name: Silencio. At first, you would mistake the

for a standard 120mm fan, but if you look closely, this black box fan has a very different sickle-shaped blade. This is what makes the fan run quietly under high pressure. In addition to the use of dynamic toroidal bearings (LDB), the

also uses Silent Driver IC technology, which provides smoother rotation and less torque boost, thereby minimizing vibration and ultra-low noise.

Although you can manually control the fan through third-party software such as SpeedFan (thanks to the 4-pin connector), you don’t have to do this to keep the noise level low. Other factors that make this fan quiet are the 4 metal screws and the 4 accompanying anti-vibration rubber screws. A great silent choice!
