1. Corsair ML120 Pro LED 120mm Premium Magnetic Levitation Cooling Fan – The Best High-Quality Case FanCorsair ML120 Pro LED, Blue, 120mm Premium Magnetic Levitation Cooling...Buy on Amazon

Pure quality products are hard to find. But brands like Corsair make the process easier. It’s no wonder that they crafted the top quality ML120 Pro LED 120mm Premium Magnetic Levitation Cooling Fan. The thing about this particular option is that it doesn’t only look amazing. Even the performance factor is on a whole different level.

The unit is available in black, white, red, and blue. All featuremagnetic bearings, which means they’re going to last for a very long time. You can fine-tune the speed of this best 120mm case fan. It starts at 400 RPM and goes up till 2,000 RPM. As for the air flow, it’s a 12-75 CFM range.

This brings me to talk about the noise the Corsair fan generates. Upon testing, I found this to be one of the silent models. But it goes without saying that higher RPM makes the machine, any machine, loud.

If what you’re aiming for is top performance, you can’t go wrong with the Corsair ML120 Pro LED 120mm Premium Magnetic Levitation Cooling Fan.

The unique Magnetic Bearing technology is responsible for providing three significant advantages. Longer lifespan, higher performance, and lower noise. If that wasn’t enough, the performance-driven motor design offers an optimal balance between high levels of airflow and static pressure. In simple words, it operates flawlessly even under challenging environments.

So here’s why you might not want to buy the Corsair ML120 Pro. The sound that this case fan produces is very high when you increase the speed.


  • The Corsair fan is made of high-quality plastic.
  • It consists of four LED lights.
  • Installing the unit is quick and easy.


  • The operation is incredibly loud at higher RPM.

2. Thermaltake RIING 120mm Red LED Ultra Quiet High Airflow Computer Case Fan – The Quietest Case FanThermaltake RIING 120mm Red LED Ultra Quiet High Airflow Computer Case...Buy on Amazon

When buying the best 120mm case fan, you end up purchasing more than a single unit. And that’s because it speeds up the process of cooling. In that case, the Thermaltake RIING 120mm Red LED Ultra Quiet High Airflow Computer Case Fan is an excellent option to begin with. This is a pack of two case fans. At the price of a single model! Isn’t that something!

The airflow value touches as high as 51.1 CFM. Thanks to the phenomenal compression blades that the manufacturer uses. These have the capacity to optimize airflow direction. So the machine can outperform the others on the list.

And despite the high power, it runs silently. The Thermaltake RIING barely emits any sound during application. You might also appreciate the anti-vibration system for mounting. Due to such a component, it becomes easier to use and fit the fan into the majority of computer cases.

Here’s another thing that makes an impact. If you wish to buy only a single piece, that option is available too. So the choice is all yours.

The current product is equipped with remarkable compression blades. These are engineered to concentrate on pushing out the air present in the inner circle. And the outcome of such an action is enabling the outer area to compress and pressurize air.

To make things even better, the mounting system is built using anti-vibration, injected-molded rubber pads. It makes the usability factor hassle-free for maximum protection coverage. And that too in all the four corners!

I can’t say that everything about the Thermaltake RIING is up to the mark. The LED lights of the unit are not bright in any way. So that does seem like a slight disappointment.


  • The Thermaltake fan is an affordable dual-pack.
  • ​Low-noise and high-quality combination.
  • Rubberized plastic holds down vibrations.


  • Not suitable for increased levels of thermal load.
  • LED is quite dim.

Don’t just buy the ROCKSOUL 120mm Blue LED Case Fan only because it’s easy on the wallet. Purchase the unit because it has the capability to deliver extreme airflow. The blades operate quietly and the bearing provides reliability. So expect to achieve the most amount of airflow with a speed of only 1,800 RPM.

What’s disappointing is the poor quality of the LED lights. They tend to stop working sooner than you can imagine.

  • ​Lights are plenty bright.
  • The cord is long enough.


  • Don’t expect longevity from the LED.

4. NZXT Technologies RF-FZ120-U1 NZXT FZ-120mm LED Airflow Fan – The Best Case Fan for Serious GamersNZXT Technologies NZXT FZ-140mm Orange LED Cooling (RF-FZ140-O1)Buy on Amazon

There are only a few case fans that gamers tend to fall in love with. And, fortunately, the NZXT Technologies RF-FZ120-U1 NZXT FZ-120mm LED Airflow Fan is one of them. It’s because the manufacturer is none other than NZXT Technologies. They are a brand known to design high-performance products but with a low price tag.

So the current pick is among the best budget case fans in the industry. But that doesn’t make them the opposite of durable. They can withstand the test of time. So all you need to do is spend little money and expect the thing to last for many, many years.

What’s more is the availability of the product in different LED colors. That way, you can get a model that suits the physical appearance of your system. So if you’re a gaming enthusiast looking for something that provides extreme airflow, you know what to get.

There’s a lot to admire about the NZXT Technologies RF-FZ120-U1 NZXT FZ-120mm LED Airflow Fan. Great price, exceptional durability, and optimal airflow. It’s all in there!

On top of that, the company has equipped the machine with 13 remarkable blades. They perform well without making any loud whining or unpleasant noise.

If you think that you’re addling with optimal static pressure, I’m sorry to tell you that you’re wrong. The pressure, in this case, is low. And that might seem like a significant setback. But to be fair, it doesn’t affect performance to a great degree.


  • The NZXT Technologies fan features bright LED.
  • ​Longevity and cooling specs are quite impressive.
  • Hooking up the blades is easy.

The fact that the ARCTIC F12 PWM Rev.2 does an excellent job at cooling is not the most convincing part. Most of the models reviewed here perform that well. So what’s the big deal if this one does it too! The unique selling point of this particular unit is its ability to run silently. Not many case fans provide such an advantage!

Another praiseworthy component is the flexible dynamic bearing system. It is the only feature responsible for the longer shelf life of the ARCTIC F12 PWM Rev.2 Case Fan. And even if doesn’t function properly, which is highly unlikely, you have a 6-year warranty period to fall back on.

And since we’re talking about silent features, you might also admire the anti-vibration silicone pads. These pads take full responsibility for ensuring that the machine only generates the humming motor sound. And nothing else!

How about the magnet technology? In the case of the Noctua NF-F12 PWM Cooling Fan, the magnet placement is quite unusual. It makes the unit more stable. And with stability, you can’t deny further noise reduction.

The seven fans focus on nothing but pushing out air at 54 CFM. As for the speed, it’s 1,500 RPM. So the specs don’t go unnoticed, no matter how many competitive options you look at!

One thing is sure about the Noctua NF-F12 PWM Cooling Fan. And that is reliability. It comes in the form of an improved placement of that magnet. To brings lots of stability into the picture!

There’s another unique quality. This best 120mm case fan is crafted to push the air in many directions. As a result of which the turbulence factor gets minimized. This is how Noctua products always end up gaining that competitive edge.

The part that might let you down is the inadequate capacity of the machine to move plenty of air through that radiator. And this does sound unpleasant now, doesn’t it?


  • The Noctua fan features silicone pads to absorb all vibration.
  • ​The blades are well-balanced for a powerful yet silent operation.
  • Adapter included to lower max fan speed.

This best 120mm case fan doesn’t take up too much room. That means you have all the space you require for other computer parts. But don’t let the compact design lead you to believe that the specs are any less competitive. The generous airflow range and fan speed of 95 CFM and 2,000 RPM respectively make a powerful, lasting impact.

As for durability, the Cooler Master JetFlois resistant to water and dust damage. But it’s the unique auto-resume operation that might pique your interest. That means the machine is well-equipped to resume operation even after an obstruction.

In all, you won’t find anything better than this for your smaller sized computer case.

You’ll be quite relieved to know that the fan blades are extremely powerful and ultra-thin at the same time! Even the motor is crafted to focus on nothing but high performance.

On top of that, the use of polyoxymethylene implies long-lasting durability. So you’re dealing with only positive results in the case of the Cooler MasterJetFlo.

But that doesn’t mean there’s no negative feedback. The unit at hand is very loud. Although typical, this particular problem has the ability to mess with the user experience.


  • The Cooler Master fan offers the strongest airflow.
  • ​Available in both non-LED and LED options.
  • Steel thread and rubber pads absorb most vibrations.


  • Poor quality control.

So you can pick any color scheme depending on your personal preferences. The most popular one being blue as it creates that perfect look for the computer build.

Now let’s talk about the more critical aspects of performance. The 1,200-RPM range is adjustable to fit your requirements. Upon putting it to use, I also marked that the machine works like a mouse. It’s that silent, unlike most of the other 120mm models currently available.

And what’s that one particular thing that accompanies quiet operation? It’s the lowerairflow capacity. In this case, the airflow value is optimally placed at 40 CFM. But you receive a pack of two case fans. The option of purchasing only one is also at your disposal.

Here’s for summing it up. The Asiahorse Solar Eclipse MIRAGE is suitable for those who want to upgrade their computer build.

Now I’m about to discuss the unknown. This particular model is perfect for all kinds of framework. In fact, it’s even ranked as the best 120mm fan for the radiator as well. Thanks to the multi-channel equipped inlet structure. Along with the innovative aerodynamic inlet fan! Even the presence of the remarkable LED lights spells out cool operation.

So what’s the one major complaint I have about the Asiahorse Solar Eclipse MIRAGE? The device’s plastic ring located outside the blade causes instability. Consequently, giving rise to a lot of wobbling.


  • The Asiahorse fan is super quiet.
  • ​The silicone pads have vibration dampening properties.

  • It wobbles quite a lot.

9. Corsair Air Series AF120 LED Quiet Edition High Airflow Fan – The Best Twin-Pack Case FanCorsair Air Series AF120 LED Quiet Edition High Airflow Fan Twin Pack...Buy on Amazon

When a brand succeeds at manufacturing a single 120mm case fan, you know it’s a catch. But what if the company does a similar job at crafting the best twin-pack case fans! There’s nothing more fantastic than that! Especially if you’re looking for this kind of a deal!

The Corsair Air Series AF120 LED Quiet Edition High Airflow Fan is one such model. The thing about Corsair’s AF120 series is that it contains case fans in various colored LED lights. Red, purple, even no light is an option here. This takes care of the looks department. What about performance? Let’s get to that below.

The Corsair Air Series AF120 Fan is designed for an increased level of cooling. Extended gaming sessions are undertakings that won’t generate a lot of heat anymore. The ultra-thin quality of the blades helps in reducing fan vibration and noise. This also implies a lower CFM range. 52 CFM, to be more specific!

Then comes the 1,500-RPM fan speed that guarantees competitive performance. Only after putting the machine to use will you be able to wrap your head around the truth. That the Corsair Air Series AF120 LED Quiet Edition High Airflow Fan is a perfect device capable of extreme cooling!

I’m going to be honest with you. The brand’s AF120 series is crafted to outperform other standard case fans. Without the shred of a doubt!

10. Thermaltake Luna Series LED Fan – The Best Case Fan in Terms of AppearanceThermaltake Luna Series LED Fans Cooling CL-F018-PL12WT-A WhiteBuy on Amazon

So you can see for yourself that the Thermaltake Luna Series LED Fan is a beautiful version. What makes it even better is that it performs exceptionally well too. That’s what you call having your cake and eating it too!

Let me begin by bragging about the mounting system. Its anti-vibration properties allow the unit to fit right into place. And it could be on all types of computer builds. So vibrations that often result in producing noise are almost eliminated! And that’s great news, isn’t it?

The next noteworthy component is the enlarged framework. It literally makes room for more airflow entering the computer. That means overheating is eliminated too.

Moreover, the fans of the Thermaltake Luna Series do more than just keep that temperature low. They are also quite appealing in terms of appearance.

So if what you’re looking for is something that scores the highest marks in the looks and performance departments, this is what you should get.

The mounting system consists of anti-vibration. The bearing mechanism brings forth long-lasting value. The double curved design of the blades provides increased air pressure. While also keeping noise to a minimum! And lastly, the larger opening of the frame enables better air flow. What more could you have asked for from a single model, right!

So here’s what’s disappointing. The Thermaltake Luna Series LED Fan and rattling are no strangers.


  • The Thermaltake fan features very bright LED lights.
  • ​Screwing in the equipment is an easy task.
  • The large frame opening is a huge plus.


  • Rattling is a part of the experience.

Buying Guide of 120mm Case Fans

If you’re a gaming enthusiast, then the best 120mm case fan is your #1 choice. It might not be the biggest option in thecurrent market. But the majority of cases are crafted to accommodate these fans.

In more practical terms, they are considered to offer the most appealing performance to price ratio. But here’s the ugly truth. The difference between the performance of a top quality case fan and a cheap knockoff is quite huge.

However, my goal was to figure out the difference in performance between the high-quality case fans. So I selected the highest rated models in the consumer market. I placed each unit under the radar to test its features and functionality. And only after doing that did I come to the conclusion that choosing the best 120mm case fan requires some basic understanding. And that’s precisely what I’m going to talk about in this guide.

How Does A Case Fan Affect PC Performance?


Photo credit:

The components responsible for driving the laptops and PCs to deliver powerful performance and speed are constantly being subjected to technological advancements. As they work, however, they inevitably emit heat that results in rising temperatures inside the case. Since these components are not meant to operate under extreme temperatures, efficient cooling systems need to be put in place, especially when you intend to work for long hours or are a serious gamer. This is where top quality, high airflow 120mm case fan comes in.

Sometimes even two-case fans are needed. You can easily find a high-performing dual 120mm case fan online for a price of one. It helps in carrying the excessive heat load that may otherwise shorten the shelf life of your PC components.

PC maintenance is incomplete without active cooling. No wonder case fans are an essential part of the process. When you properly position the best 120mm case fan, it eliminates hot air from all vulnerable areas. Especially the heat sink of the CPU! At the same time, it pulls in cool, fresh air.

What Factors To Take Into Account When Buying Case Fan?


Photo credit:

There are certain aspects that are important when it comes to buying the best case fan. So let’s find out what they are!

  • Dimensions/Size

In terms of size, there are many different options available in the current market. With that in mind, what we’re looking at here is the best 120mm case fan. So you know that the size is categorized using millimeters. But what you probably might not know is that case fans range from 40mm to 140mm.

It’s only logical to think that larger fan blades generate more air circulation at any given speed which means that a 120mm case fan tends to run at a higher speed compared to a 140mm so it can push maximum air to match the capacity of its larger counterpart. As a result, smaller case fans are audibly louder while the larger ones are much quieter.

More often than not, we want to pick a large fan that can accommodate the specific parameters of your case. Any average case has the ability to support a size of 140mm and 120mm case fan dimensions. In this article, I’ve only covered the latter due to its sheer compatibility and popularity. But, hey, don’t get me wrong, because you can still find plenty of smaller fans that operate in a whisper. Take the Antec TrueQuiet, for instance. I may not have included it my Top 10, but the Antec 120mm case fan can also be an option.

  • Fan Speed

Another crucial factor related to size and performance is the fan speed. It is measured using RPMs. Fan speed is considered to be a significant contributing factor for generating audible noise. In that aspect, if you want something that works silently, it’s better to purchase a bigger fan that can operate at with lower RPMs. This particular model doesn’t spin as quickly, hence noisily, as its smaller sibling.

Keep in mind though, that fan speed and blade size aren’t the only factors that affect quiet computing. Fan bearings may also play an important role. FDB or fluid dynamic bearing fans are comparable with sleeve bearing fans in delivering low-noise output. Ball bearing fans, on the other hand, tend to produce noise toward the end of its life span.

  • Pins

The power distribution of fans consists of a 3-pin or 4-pin connection. The former is a standard design that allows the equipment to function at top speed. Unless its voltage is reduced using the motherboard.

As for the latter, you can control it using separate software. And the outcome of such a structure comes in the form of minimal energy costs. In fact, it also enables fine-tuning the speed in order to enhance performance. While also reducing the undesired noise to a great extent!

  • Air Flow

The air flow of case fans is measured using CFM or cubic feet per minute. The more air the fan is able to move per minute, the higher the cooling capacity. But this comes at a cost. Meaning, a higher CFM also implies a higher level of audible noise (and maybe even higher power consumption). This is why most people prefer high static pressure fans over high airflow fans.

It’s interesting to note that you have an almost endless list of options when it comes to choosing the best cooling system for your case. The market is overflooded with fan kits and different fan design to suit every gamer’s needs and preferences. For an added appeal, you might want to consider getting a 120mm led case fan. Frequently, this PWM fan comes in different colors and has a fan controller that allows you to control its speed to either maximize or minimize airflow and noise level.

What Is The Correct Case Fan Placement?


Photo credit:

Now we know all about the best 120mm case fan,but not many of us know the answer to this question. It might seem like a straightforward question, but the answer is not so, as it largely depends on different variables.

But after testing and reviewing so many different models, I have come to one conclusion. The optimal placement consists of a single fan at the back, two on top, and two at the front.

However, if you’re dealing with only a single fan setup, the best way to go about it is to place it in the rear. When positioned in that spot, it helps in achieving cooler temperatures for the internal case, ​and it does so by eliminating hot air present inside that case into the surrounding/exterior environment.

Another factor that may dictate the positioning of your fan inside the case is the type of bearing used. If you have a 120mm computer case fan with a sleeve bearing, it’s usually suitable for vertical mounting instead of horizontal. This is because the lubricants inside the bearing will get tipped to one side if the fan is placed horizontally, thus preventing it from providing uniform protection against friction. Sleeve bearing fans, therefore, are the best choice for vertical placement.

Final Review on Best 120mm Case Fan

My Choice: ARCTIC F12 PWM Rev.2 Case Fan

The consumer market is up to the neck with such technologically advanced products. So it’s no cakewalk to choose the best 120mm case fan. In that context, please feel free to select any model from the 10 options reviewed above. They’re all high quality fans as far as performance goes.

But my top pick is the ARCTIC F12 PWM Rev.2 Case Fan. Its innovative fan blade design improves air flow while also facilitating highly effective ventilation! At the same time, the remarkable impeller focuses on reducing the  noise level. Even the service life of the gear is impressive. Thanks to the addition of the flexible, dynamic bearing system. So it’s all covered!
