Best 120mm Case Fans & 140mm Case Fans

Here are the reviews of best 120mm case fans and 140mm case fans in 2022. All fans are available in different sizes. Most common sizes are 120mm and 140mm. In this reviews, I will be talking about 120mm and 140mm computer case fans. Before buying a case fans you should check your case size. Read this guide to measure fan size.

1. Corsair ML120 Pro LED – Best Overall


When it comes to buying a case fan, Corsair is the best and most popular brand.

The main reason I love this it is a magnetic levitation bearing fans. The magnetic levitation bearing fans has no friction because of the fans shaft’s and the bearing doesn’t touch. As a result, you will get lower noise, longer life span, high airflow.

As I said there is no friction present, the fan is faster and has a better performance too.

The air flow is also amazing in this fan. You will get anywhere between 12 to 75 CFM without any trouble. That makes it an excellent choice for a case fan. It would do well in the front casing as well, provided it has some space in front of it.

The product has a 2400 RPM top speed. Now enjoy everything from lower noise to best cooling performance. However, the fan does get quite noisy at the top speed. They can cool down the CPU even with extended gaming.

Case Fans Buying Guide – How To choose right Case Fans

It’s a well-known fact that when we get angry, we tend to lose self-control, we make stupid decisions, and we create wounds that are difficult to amend. Well, a computer acts similarly. When hot, it may underperform, throttle, and may well ruin your day. That’s where a Case Fan will help you to cool down the system and get it back on track. Most of the PCs have pre-fitted fans, but they are not the best in the business. For the best performance, you will have to buy an aftermarket case fan.

Fans come in different sizes, different varieties, shapes, design and different specifications. You will have to be careful to choose the best one for your PC. No need to panic. We have you covered. This case fans buying guide will help you to select the good case fan as per your requirements.

Size of the fan:

The first thing that you need to keep in mind is the size of the case fan you will need. A standard case fan ranges from 25mm to 250mm. But the most commonly found categories are 80mm, 120mm, 140mm, and 200mm. I am pretty sure that you will not want to buy a fan that will not fit the case. So read further to know more about the various commonly found sizes-

80mm Case Fans:

Being the smallest amongst the most commonly used sizes, it produces less air and is the cheapest amongst the commonly used lot. It also has the knack of producing the most noise. It is suitable for your PC if your system generally doesn’t get too hot. It still produces very good airflow considering it’s size.

If you are looking for a model of this category, you may want to look more for a durable product instead of its quietness and its added accessories. If you normally switch off your PC and it’s used only when required, then you can opt for this type without any further questions. It’s an excellent option for systems with low processing power.

120mm Case Fans:

This type of case fans are bigger than the 80mm ones mentioned above and naturally, produces more airflow. They are equipped with larger blades, but their size somewhat restricts the airflow.

It also tends to spin slower than the 80mm case fans, and it can move almost the same air as compared to the smaller fan given its slowness. It also tends to produce less noise while in operation, which makes it a better choice.

140mm Case Fans:

They have received stardom very recently. They have larger blades than the normal ones, and hence they can operate slowly without even affecting the airflow. This adds to its longevity and reduced noise levels.

They have two very useful features-

  • They have interchangeable rims in most of them. And
  • You will find some of them with mounting holes spaced in an exactly similar way like that of 120mm, which means that if you have enough space, you may well use a 140mm one instead of the 120mm model.

200mm Case Fans:

These, being the largest ones are also the quietest of the lot and is naturally capable of producing more airflow than the rest of the above-mentioned categories. In size it’s big, it requires a lot of power to operate, and they feature large blades to reduce operating noise and improve airflow.

It provides the best cooling when compared to the other categories, and they mostly are equipped with the 3-speed manual switch that can help us to find the right balance. It is the costliest and tends to have the highest lifespan.

Does Case Fans size matter?

The size of the case fan determines a lot of its characteristics, and it’s extremely important to find one that suits the level of performance your computer has. As aforementioned, the size of the fan determines the amount of air it can generate. Further, the size of the fan determines the amount of cooling your system is capable of generating.

You can prioritize the cooling factor of the case fans and hence buy a fan which is bigger and produces the highest level of cooling. You may well consider the noise your fan produces. Here also, the biggest one has an advantage over the others, but in the current market scenario, the smaller ones produce noise that is not unmanageable and can be dealt with.

What is the good case fan size?

It’s pretty clear now that the biggest fan size wins the battle quite comfortably. It has the lowest level of operating noise, last the longest and produces the most airflow, but it’s also the costliest and needs the most space. But the fan you need to buy depends on the specifications of your PC, and hence the case fan size can be a relative term.

Static Pressure Vs. Air Flow:

Static Pressure:

One of the things you should look for is Static Pressure. It essentially stands for the pressure in which the fan circulates air through a small space. As a general rule of thumb, fans with higher static pressure are better for heat sinks and cooling radiators. Also, they are also very good as chassis fans. You can place them in front of the cases as well. High static pressure helps you to cool the CPU efficiently. The blades of these fans are made in such a way that there are lesser gaps in between them.

Air Flow:

Air Flow represents the amount of air moving through an opening. It is another aspect that you should look for when making a decision. The air flow of a fan is measured in Cubic Feet per Minute (CFM). Fans with higher air flow are best suited to be used for case fans. They perform at their highest level when there is a certain amount of space in front of them. However, make sure not to mount them in front of cases or on the radiator. You can distinguish them from static pressure optimized fans only by looking at their blades. Higher air flow fans have blades that have larger gaps between them.

As we have already read about the various aspects of a fan based on its size, let’s discuss some other aspects of this field-

Fan Speed, Noise & Vibration

RPM (Revolutions Per Minute):

A fan’s speed is measured in RPM (revolutions per minute), and it’s one of the main contributors to the performance of the fan. Faster fans will always generate more airflow but may also the highest operating noise. Whereas a slow fan will create less noise but also less airflow.

As always, a balance between the two is the need of the hour. You will get better performance and consume lesser power if you find the right fan. A large fan which operates at lower RPM is a great choice since it will generate enough airflow and will save energy at the same time.

CFM (cubic feet per minute)

Air flow of a fan is measured in CFM(cubic feet per minute). It determines the level of air the fan can fill up in a minute. The better the CFM, the more powerful the fan is since it generates the highest level of airflow. RPM also affects CFM, and your choice should be a proper balance of both which may help you to maintain a respectable level of noise while not taking a hit on the performance.


The noise of a fan is computed in dBa(decibels), and generally, a fan has a noise level ranging from 10 dBa to 36 dBa. And the preferred one is the fan with the lowest dBa. You will mostly find that the manufacturer will provide you with the level of noise of his fan.

Bearing Type

Sleeve bearing:

Mostly used in small toys, they use liquid-based lubrication to reduce friction, and they are mostly for one-time use. They are very affordable and should last around 40k hours(at 60C) while being continually used before you may require a replacement. They have a low operating noise since the fan speed is low and are mounted vertically in any axial orientation. Such fans can suffer from immediate breakdowns without any warning and are highly volatile.

Double ball bearing fans:

They have a longer lifespan than sleeve bearings, and they should last up to 60k to 75k hours (at 60C) of continuous usage and are louder than them. They have a higher temperature tolerance than sleeve bearings. They too can be mounted in any axial orientation. They are mostly used in Server-farm environments and are not recommended for home usage.

Fluid Dynamic And Hydro Dynamic Bearing Fans:

They have the lowest noise levels because they use the fluid cycling technology. They have a lifespan ranging from 100k to 300k hours depending on the selected fan. They are very quiet throughout their lifespan and can be mounted without any issues.

Types of Power Connector for Fans

Connectors are of three types-

  • 3-Pin
  • 4-Pin and
  • MOLEX Connectors

4-Pins fans can be software controlled while the other lack this facility. Fans with MOLEX connectors can be connected hassle free if you have its cable. Rarely they need an adapter.

Fan Filters & Dust Protection

Fans, like most other electronic items, are prone to dust over time. Dust collection can result in higher noise levels and reduced RPM. If not cleared timely, it may eventually lead to complete failure. Fan filters are used to prevent and minimize this problem. They don’t affect airflow and can be set up to prevent dust to flow towards the fan. They need to be regularly cleaned as the dirt keeps on piling on them.

What To Look For Before Buying Case Fans:


Furthermore, you should also check the speed of the fan. Case fan speed is represented by RPM or Revolutions per Minute. In a broad sense, the higher the RPM value, the more air it can gather. However, the performance of the fan also depends on various other factors such as static pressure and airflow. The RPM has a direct relationship with the fan’s noise level as well.

Sound Level:

Another important factor to consider is the sound level of the fan. You should be able to check the fan’s sound level in the package itself. They are measured in decibels (dB). In general, these fans range from 10 dB to 36 dB. Now, it is suggested, as you might expect, to get the fan that produces the lowest amount of noise. If the sound is louder, then it will create distractions, and your work will be hampered.
