There are a wide variety of options available to you when it comes to pc case fans, it is important to choose the right one for your individual case.

Jump straight to the TOP 4 best silent housing fans

To help you out, we’ve created this comprehensive buyer guide to explain how a fan cooling system works and how to choose the best fan for your PC’s case, components, and other specifications. Before you start shopping, you’ll want to double-check the size of the case fans in your case and how much free space you actually have inside the case to buy a fan. In some cases, you may need more than one fan. Indeed, it all depends on what you are trying to do.

At a Glance:

What is the role of the cooler / fan in computer performance?

As technology advances rapidly, so do our PCs and laptops.

If the performance of the systems is constantly increasing, we cannot say the same about the cooling fans of the housings, unfortunately they have not changed at all.

Therefore, an unventilated housing can affect the life of the entire system. Regardless of whether you have a PC gaming case, it is good to ensure good air circulation through the computer case.

With a correct positioning of the fans, we can achieve a simultaneous ventilation of both processes, bringing fresh air into the housing, while another fan / s removes the hot air produced by the components.

How is it best to mount the fans correctly on the housing?

It’s not that difficult, we just have to pay attention to the details. I drew a diagram about how to properly mount the fans on a housing.

The blue arrows represent the cold (fresh) air that must be brought into the carcass, and the red arrows represent the warm air that must be taken out of the carcasses.

So, we are going to put the fans to draw cold air from the base and in front of the housing, so we will push that fresh air towards the components.

The laws of physics say that warmer air rises naturally upwards, so the top fans in the enclosures have the role of pushing that hot air out of the enclosure.

How do I know which side of the fan draws air and which pushes the air?

Here is the confusion of many, I do not know exactly which part of the fan draws air and which side pushes the air.

The part that draws the air is the mobile one, the part of the fan that moves to the left of the image is the one that draws the air.

The part that pushes the air is static, the fan part on which the motor is placed is fixed, the image on the right side, so on that side the air will come out.

There are also small exceptions, if the polarity of the fans changes, they will change their direction of rotation.

So now you have an idea of ​​which part of the housing is responsible for bringing in fresh air and removing it… you also know the direction of the air flowing through the coolers. All you have to do is mount them.

Make sure you buy the right size of fans for the housings of each of you. The best housing fans are 120mm.

How do case fans differ from processor fans?

Fans with larger and smaller blades / propellers are recommended for radiator coolers, eg processor cooler

Fans with narrower blades / propellers and more in number are recommended for PC cases.

The advantages of those with multiple propellers / blades are that they direct the air over fixed portions and over longer distances, and those with radiators push the air over larger and shorter surfaces, for example radiator surfaces that are immediately next to fans.

What does CFM mean for PC case fans?

CFM = Cubic Feet per Minute


The airflow in the imperial system is noted, not the metric one.

This is how the air flow / volume that a housing fan can bring / push as needed is measured.

The bigger the better. I must mention that the noise produced will also increase in proportion to the volume of air that a PC case fan is able to dislodge.

Recommend the Best Pc Case Fans

I will give some examples of very good fans for PC cases. One that I recommend for the quality of the fans and their quietness, but they are a little more expensive, and one in the cheap segment.

Air flow: 63.4 – 92.3

Noise level: 12.6 – 19.8

Operating hours: 150000

A truly quiet fan even at top speed. By the way, between 900 and 1300 rpm. The airflow is decent for such a very quiet fan. Of course, the price is not the cheapest, but the performance is among the best in terms of price / performance / quietness.

Keep in mind that such a fan should last 50 years if it is well maintained and not exposed to water. It is a purchase that lasts longer than all the other components in your pc.


  • Very quiet
  • Decent air flow
  • Rubber grip system


  • Nothing

Air flow: 53 CFM

Noise level: 20 dBA

Here’s a cheap fan model as an alternative. It is very cheap and cannot be denied for 2022. It is not the quietest housing fan, but at low speeds it will be inaudible.

User Experience: I recently purchased the Cooler Master ML240R liquid cooler, but after a short time the fans started to give noise problems, and almost exasperated when rendering the videos I wanted to buy these fans, hoping to remedy the problem. without spending a fortune on RGB or anything else.


  • Cheap
  • Silent at 900 rpm
  • Decent air flow


  • Do not vacuum the house

Addressable RGB

ASUS Aura Sync â


MSI Mystic Light Sync

AsRock Polychrome

I found this fan kit for rgb addressable computer cases. Addressable means that you can control from the software several nuances and how the lighting interacts with several factors, for example: music, different software, etc.

The non-addressable ones have limitations in terms of light control and only have the default shades of red, green, blue.

These fans are for those who like to have games of lights in the case and who emphasize this. At the same time, it maintains a decent efficiency for cooling the PC case with a good quietness in this case.

They become very noisy only at maximum speeds, at minimum rotations they are very quiet and have a large volume of air (56 CFM). Ideal for a medium / high end gaming system.

They are the best pc case fans with rgb lighting in terms of quality / design / price / performance.

They can be attached to an LED strip lighting system.

  • Beautiful design
  • Quite strong lighting
  • Quiet even at higher revs


  • Cables a bit thick

Power Connector Type 4-Pin

Voltage 12 Volts

Controller included

Here is one of the best price and quality ratios for this kit of two RGB fans that also include the controller in the package.

The fans are surprisingly quiet and reach 1200 rpm. The controller helps to set the rotation speed and LED lighting modes, and the controller itself is powered by the sata connector. But you need to find a place to mount that controller in your case.

The downside is that depending on where you place the controller, it will always need to be handy if you want to change the rotation speed or colors.


  • Quiet
  • Easy to install
  • Pleasing rgb colors not exaggerated


  • At maximum speeds they sound quite loud
  • Additional wire-management space for controller


Don’t neglect the importance of ventilating computer cases, the best case fans also depend on your cases.

Leave feedback in the comments section if you don’t know how to choose the best case fans and I’ll help you as soon as I can.
