The process of choosing the right product for our guide is long. We will not blindly recommend the first thing we find. In fact, there are many products that have not fully passed or appeared in our guide. The reason is simple-we want to make sure that your hard-earned money is spent in the best way.

When compiling our list of the five best 120mm fans, we first conducted a thorough research. We have read all the specs, compared them to other models, and then directly benchmarked performance. The following is user feedback. We believe that other users like you (like us) are one of the best sources of information when it comes to creating PCs.

Once all of this is done, we will run a test, which is possibly the best part of our research, provides us with all the information we need for a product that we believe is suitable for you.

We believe that everyone should have access to PC builds, but we also realize that creating a great PC takes a long time. That's why we like to save you time and do all the research for you!

As mentioned above, testing can be the best part of our product research. Nothing can show the true colors of the components like a good stress test. Many fans will surely perform well without being nervous, but what about demanding tasks that you want your PC to run smoothly?

Even if you're running the latest games or 3D modeling software, a good fan will maintain the temperature it should be, which is what we are looking for when testing. There are many important factors for the

chassis fan: airflow, RPM, type, etc. All of these are incorporated into the great work that fans can do. Another thing that cannot be ignored is whether the fan makes noise when running at high speed.

We will consider all of these when testing the fans we now recommend. Each of them has undergone extensive stress testing, which means we know they perform well under pressure. Only when you push the fan to the limit, you will know how good it is, and this is what we do.

also considered build quality, efficiency, and longevity, and now we can say for sure that the fan you'll find below is the best. They should be a very worthwhile investment.

You've seen our best case fan, so you may already have a favorite. But don't fire right away, there's more to know! Factors such as size, type and construction are being selected.

What you have to remember is that the fans have changed a lot more than they appear. Although they may appear similar or even the same on the surface, it is not that simple. One of the differences that most worries people is the type of bearing. The type of bearing used in the

fan has a great influence on its performance, noise and life. For example, it is well known that sleeve bearings are quite inexpensive, but have a shorter service life than hydrodynamic bearings.

What types of bearings are there and which are best for you? The

sleeve bearing is probably the most popular choice, often found on budget and mid-range drilling rigs. Due to the use of self-lubricating porous sintered sleeves, they require relatively little maintenance or replacement. They must be installed vertically so as not to affect their performance.

These bearings perform quite well at moderate temperatures, but may fail at high temperatures, and the risk increases with age. Generally speaking, they have a good service life of about 35,000 to 45,000 hours in an environment of about 50 degrees Celsius.

fans that use slide bearings are generally cheaper and very quiet at lower speeds, but like the risk of fan failure, noise increases with age.

These bearings are improved cousins of sleeve bearings, with greater durability, lower noise, and longer life. They are not subject to the same installation restrictions as sleeve bearings and can be installed regardless of direction.

Their advantage is that they can maintain good performance for a long time even at high temperatures. At an average temperature of 50 ° C, a ball bearing fan needs approximately 60,000 hours or more before its time expires. The

rifle bearings are also similar to sleeve bearings and are becoming an increasingly popular option in certain configurations. They have a spiral groove that can pump fluid from the storage tank so that they can be safely installed horizontally and vertically. Pumping ensures a sufficient quantity of lubricant, reducing friction and noise. The noise level of the

rifle bearing is quite low and the service life is similar to that of a ball bearing.

These types of bearings are usually the most expensive, but they are also the most effective. Fans using FDB or HDB will have the best of both worlds, combining the excellent quality of other bearing types into one reliable choice.

They can be placed in any position horizontally or vertically, and have an extraordinary service life. As we all know, some of the best models give up 300,000 hours of good performance before finally giving up.

bearing types play an important role in choosing a good 120mm chassis fan, but they are not the only factor to consider. To make things easier, let's summarize the different types and quickly describe their advantages.

Consider the above qualities. Remember, as fans get older, most of them will get louder over time. This means that even if you invest in a superior FDB fan, if the noise becomes annoying, you may want to replace it long before it expires.

In addition to bearing types, chassis fans have many specifications that can seem confusing. Whether you're not very technical or completely professional, it's hard to remember all the different terms or even what they stand for, let alone what is important.

Choosing a good fan is very important, let us help you. Here are some other important factors to consider before placing an order.

To determine compatibility, you need to choose your motherboard and check the pins it supports. The fan comes with different types of pins. You can also choose an adapter, but in general, it is best to buy a model that suits your specific configuration.

You buy a fan because you want to keep your computer cool, it's that simple. Therefore, factors such as appearance and brand play a secondary role in the absolute cooling capacity provided by the fan.

fan power is listed in CFM (cubic feet per minute) and RPM (revolutions per minute). CFM measures the air flow that a particular fan can provide, that is, how much it can actually cool in your situation. On the other hand, RPM is just a measure of how fast the fan spins per minute.

The general rule of thumb is to achieve a high CFM with a goal of a medium RPM. Although a high RPM fan is obviously powerful, it can be loud at times. However, thanks to modern technology, even louder fans are usually quiet enough not to disturb at all. The noise emitted by fan

is measured in dB (A). Most fans fall into the 15 to 30 dB (A) category, which means that the amount of noise they produce ranges from the sound of a needle dropping to a whisper or quiet conversation.

There are many factors at play here that determine fan noise. Generally speaking, when you do some heavy tasks on the computer, the fan speed may increase, so the sound will be louder. With age and excessive use, the sound of the fan will get louder.

Our list includes some very quiet options, so remember them!

is directly related to the type of bearing. The lifespan of a fan is greatly affected by how often it is used and the temperature at which it is generally forced to work. Different types of fans have very different lifespans - depending on your fan, you can expect 30,000 to 300,000 hours.

If you leave it on your own device, the fan will eventually hang and stop working, but you may get an update before then. The

color LED lighting is still a first in the field of computing, but it is

Easily adjust the color mode.

In some cases, the style is quite small and may not be an obvious candidate for the popular colors provided by these LED fans. However, even the simplest case is a beautiful canvas drawn by these fans.

We are very aware that budget always plays an important role in any purchase. Not many of us have the opportunity to buy the first thing we see, but in the case of PC builds, this is a good thing. A little research will go a long way to ensure that you buy something that you really like! The

Case fan price varies with additional effects such as size, efficiency, manufacturer, bearing type, and LED lighting. The 120mm fan is in the middle position in terms of price, but even within this range, the price difference is large.

Don't forget that in most cases you will buy more than one fan, which means that the cost increases exponentially. The most spacious box can hold up to 6 additional fans, so you can collect as many as you like.

We believe in value for money and look forward to helping you. So, before we continue reading our detailed product reviews, let's take a look at the approximate price of your future 120mm fan.

As you can see, the price is largely affected by the build quality you are trying to propose.

Saving money by choosing a cheaper model is often more profitable than avoiding it (for example, replacing the GPU). However, if you want to build a real PC beast, it's definitely not cheap for fans. They are some of the most important components.

This award-winning product comes from Noctua and is effortlessly on board Up our list. Noctua is a trusted brand that can provide the best products in refrigeration. Assuming "the best and the best" is the goal, we sincerely believe that this fan has achieved it.

On the basis of aesthetics, they are very simple, and for some people, they can be considered a weakness. This is a matte gray fan without additional lighting effects. However, this may be a good thing, because too much LED lighting may overwhelm the style of some buildings. The color of the

fan is very interesting because it is different from the owl's unique mix of tan and brown. We think this is a good thing for most people because the fan is perfectly integrated and will not collide with any part of your build.

High performance is what we are after, and this is what we get. The combination of a large CFM (60) and a medium RPM (1200) means that the fan can produce a steady airflow without too much noise. Some of

Noctua's tried-and-tested systems have been implemented here, such as its SSO bearing, which combines the concept of a hydrodynamic bearing with an additional magnet to support the rotor shaft. This ensures long-term stability and unwavering performance. The

fan frame can be extended with Noctua chromaxline anti-vibration pads. These come in a variety of colors and have a dual role, both to suppress vibration and to add a layer of customization to your build.

Whether you are building gaming equipment or office computers, Noctua is a brand known for its excellent coolers. After trying this, we can only recommend it wholeheartedly.

Impressive build quality


requires proprietary hardware - Corsair RGB controller (included)

RGB builds are all the rage in recent years years. We remember when clear shell construction wasn't as popular as it is now, it's been a while! Nowadays, in most cases, there is at least one tempered glass window that allows you to take a look inside ... what's inside is usually amazing.

Whether you prefer full RGB rainbow colors or monochrome settings, you can use Corsair's magnetic levitation series to achieve just that. In this set of three premium fans, in addition to the default rainbow hue, you can also choose from different color settings.

All its shiny aspects aside, this is just a solid set of fans that can effectively cool your build regardless of the situation. Are

The fan is not bad. If you'd rather buy a few extra fans at a better price than splurge on higher-end options, check out Cooler Master's SickleFlow model.

This is an LED fan that ticks all the boxes without being too expensive. It has some of the best price / performance ratios that we see on the market today. One of our favorite things is the subtle LED lighting.

Please note this is not an RGB fan. It has LED lighting, but only one color: electric blue. This makes it well suited for most situations, adding pop colors without getting depressed.

Considering the moderate price, the cooling effect of this model is very good. At a maximum RPM of 2000, you can expect up to 69 CFM. Even at high fan speeds, SickleFlow remains quiet and does not exceed 19 dB (A).

discharges a large amount of cold air at an extremely fast speed, and the difference is felt immediately after opening. The heat dissipation of some fans is very subtle, but with this, you can really feel the effect of installing it.

For plain bearing fans, the life expectancy is quite long. Cooler Master promises about 50,000 hours of use at moderate temperatures and is located on the top bracket of the sliding bearing fan.

If you are a newbie, the installation can be a bit complicated, but we are sure that anyone can do it. Other than that, this is a very reliable fan, especially if you want to be profitable when preparing new versions.

Are you a fan of the pure version of the game? They have a specific take on them, they really do look like beasts, in a good way! If you like the look of black and red computers, this Corsair Air fan will appeal to you right from the start. However, the interesting appearance is only a reward for the tranquility and efficiency of the product. The

uses deep red LED lighting, which looks great on most equipment. The color is static and cannot be controlled or changed, so if you think red is not suitable for your build, look for one of the other Corsair Air models. Although the

measured the maximum noise level of 25.2 dB (A), we found that this fan is excellent in terms of quiet performance. Even at full speed when pushed to maximum, the fan is still as quiet as it was from the beginning.

Good performance exceeds the noise level of this fan. With a CFM of 52.19 and a maximum RPM of 1500, you can expect high airflow without a lot of noise. The turbulence of this model is also very small, so there is no wobble or shake inside the case.

These airflow fans work best in unrestricted spaces and are not suitable for compact chassis with tight spaces. However, as long as there is a gap of at least 3 cm on each side, you can expect excellent results. The manufacturer recommends installing them on the back or top of the PC case.

Corsair's Air series AF120 dual fan group excels in combining a moderate price with first-class performance. We think they will be a great addition to any build, with a focus on mid-range gaming equipment.

If budget is not an issue, you can also do your best to invest in a fan that will definitely make you happy for years. This fluid dynamic bearing fan will greatly help achieve this goal.

This is a high-end model, reflected in the price. However, just in terms of specs and appearance, we won't regret picking it up and installing it in our own home.

Like many other RGB models, the first thing you'll notice is the layout. It has some of the most enjoyable solutions we've seen on the market. The LED lighting isn't too bright, but it's still full of energy.

is highly customizable too - you can switch between different color schemes to match your specific sense of style, ranging from deep purple to bright yellow. All control is done through the NZXT system. The

fan can also be adjusted through the NZXT software, which is good for some people, but less for others who like to use the controls on the motherboard. We found the control panel to be easy to use, and switching between 50,000 and 1,500 RPM was a breeze.

This fan is an expense due to the use of fluid dynamic bearings, and once incurred, you will benefit in the next few years. Some FDB fans expect to reach 300,000 hours, so they will almost certainly live longer than most other fans.

We recommend the NZXT AER RGB 2 fan for high-end game builds that require optimal cooling-the stunning appearance is just a welcome bonus!

Choosing the best case fan seems to be a tedious task, so we did our best to relieve some of the pressure. It will be fun to build a new PC. We hope that with our help,
