The new decade is here and with it comes a new generation of fans. A new generation of fans that have been made to be quieter and quieter with each generation. Now new fans have been made to be even more silent. Fans that have been made to please the ears of gamers. Fans that have been made to keep the components inside the case cool. Fans that have been made to keep the components inside the case from being destroyed from being damaged by the heat. Fans that have been made to keep the components inside the case from melting due to the heat. Fans that have been made to keep the components inside the case from exploding due to the gravity of the components. Fans that have been made to keep the components inside the case from getting messed up

Most gamers have a lot to think about when it comes to case fans, but what can they expect from a 140mm unit? It is a question we have been answering for a while now, and this guide is a must-read for fans of the hard drives, as it explains all the pros and cons of the most popular cases on the market.

There are so many different case fans out there, it can be hard to pick the best one. To help you with your decision, we’ve tested the top options on the market to bring you the list of the best 140mm fans for all your computer needs. It’s important to know that case fans are not just for cooling down your PC, but they can also be used to push air out of your computer, to improve the cooling of your GPU, and even to improve the airflow of your whole case.. Read more about best 140mm case fan 2021 and let us know what you think.

Many stories regarding the on-spree use of a large number of fans in a system have been documented in various study publications. Because you’re creating a beast of an order, the possibilities of temps rising are at an all-time high, the rationale was perfectly reasonable. Because no one like cooking their components, a study was conducted out of pure curiosity, and it was discovered that consumers were more interested in purchasing case fans without having a command of the necessary knowledge. This page covers all of the issues that have been reported as well as how to buy case fans in a more professional manner.

High-end components, such as the newest GPU products, are known to need greater TDP, which unfortunately results in higher power consumption. As a result, more heat is radiated. The role of the case fans now enters the picture. To turn some of the fans into intake fans, they are rotated 180 degrees. The front fans are usually designated as intake fans, while the rear fans are designated as exhaust fans. You don’t need to go into great detail regarding intake and exhaust fans since the topic isn’t nearly as complex as the fans’ function.

The majority of Chassis cases are designed to comfortably accommodate 5 to 6 fans, which has been a standard number in recent years. There are a few things to bear in mind while purchasing fans. Even so, it’s a good idea to search for RGB lighting that matches the other components in the casing. We’ll start by talking about how noise levels, airflow, and size all work together to make a good fan.

Because this page is about 140mm case fans, all of the items listed below are the same size. As a result, remain connected and informed!

The Top 8 140mm Case Fans

1. Corsair AF140 Air Series


The Corsair earning the top position on the list of best 140mm case fans is unsurprising. The Corsair Air Series AF140 LED is a multipurpose fan that delivers excellent airflow and static pressures. The fan is quite light, weighing just 6.2 ounces, making it easy to transport. The voltage rating of these fans is 12 volts, which is an important factor to consider. If the RGB headers on your motherboard are 5 volts, don’t even attempt to put these fans on them. It’s possible that you’ll wind up breaking the warranty.

These fans come with a set of connections and are packaged in a neat manner. The fans have a 3-pin connection, while the LED lights have a 4-pin connector. The fans’ greatest feature is its efficient design, which includes custom-molded fan blades. They maintain a continuous flow of high-volume air into the enclosure. When compared to other current fans on the list, the blades are narrow and generate low noise levels. It also has a bearing to assist reduce vibrations produced by undesired resistance. It’s also worth noting that these fans don’t come with RGB, so don’t hold your breath.

Not to add that these fans may be simply installed on the case’s top, exhaust, and back sides without obstructing or blocking other fans in the area. You don’t have to do much during the installation procedure other than connect all of the connections to their correct locations and properly screw the fans. That’s all there is to it; your fans have turned on. There is another alternative, which is to connect directly to Molex, however this would cause the system to operate at full speed all of the time.

Furthermore, Corsair’s proprietary software allows you to customize the LED patterns.


  • It comes with its own packaging and instruction manual.
  • High CFM
  • Directing is simple.

2. PWM Noctua NF-A14


Fans of Noctua are renowned for their role-playing simplicity. The majority of their fans are basic, old, and capable of delivering excellent results. If you want to obtain the greatest results, the Noctua NF-A14 PWM is the way to go. These fans continue to blow at a faster pace, providing adequate airflow to your case and keeping the temperature below the set point. It’s worth noting that these fans operate at a relatively modest volume. Despite the fact that they will be operating at full capacity, you will not hear anything. That’s what makes the Noctua NF-A14 PWM so appealing.

The only thing that prevents consumers from purchasing this fan is the color scheme and code. As I previously said, Noctua is a fan of minimalism. You don’t receive any RGB or LED. In this day and age, most gamers want their casings and systems to stand out from the crowd so they may brag and appear expensive. But you’re not even close to becoming flashy with Noctua. You shouldn’t worry about your appearance, in my view. What counts is the cost and the effectiveness of the product. And Noctua succeeds in giving its clients the best.

Furthermore, when compared to other models on the list of 140mm case fans, the static pressure is quite typical. Because of the bearings utilized, the fans are also known for their anti-vibration mode. These bearings are specifically placed to prevent any kind of vibrations since they may send uninterested pulses all throughout the motherboard, reducing component life. Well, each fan will set you back about $20, which is very reasonable.

Overall, if you’re looking for performance, Noctua is a great choice.


  • Airflow is unusually high.
  • Noise levels are lower.


  • Color coding and scheme are out of date.

3. HD Series 140 RGB Corsair


It’s just the way it is. People generally cheer for Corsair goods because of their high performance and efficiency. These fans blow strong gusts of airflow into the enclosure, causing the temperature to drop dramatically. Corsair has a reputation for giving customers complete control over their goods, and the HD series 140 RGB is no exception. You may adjust the BIOS settings or use third-party software to manipulate the dancing lights as you like. The fan is lightweight at 7.8 ounces, giving it another portable and light-weighted option in the category.

Not to mention, you receive a cutting-edge design and layout that is a visual feast for the eyes. With sluggish tides, the RGB is rhythmically breaking down and rising. It’s just spellbinding. As a result, adding these fans just makes your case more visually appealing.

Noise levels, ventilation, and static pressure are all notable characteristics for the Corsair lineage. Noise levels are about 28.6 dB, which is tolerable. Surprisingly, you also receive an additional controller that allows you to adjust the settings, speed, and lighting as you want. Explicitly speaking, controllers cause a long-term disruption in the stability, therefore it’s preferable to adjust the settings through software, but the option is still yours.

When it comes to modes, there are approximately seven of them, each having 12 different color spectra. Regardless, the fans have amazing blade designs that push air into the enclosure at a rapid pace. You must be fascinated by the turbulence and vibrations produced by spinning. It’s not a lot. You have bearings fitted, which reduces the quake’s intensity significantly, which is a good thing.

You receive a 3-pin RGB cord with a 4-pin connection for turning on the fans as far as cords and cables go. Installing them is a time-consuming procedure. On the RGB hub, you must connect all of the 3-pin RGB connections. The remainder of the wires will either go to the Molex or to the motherboard’s RGB headers.


  • Fans that are quiet
  • Durable
  • Efficient
  • Increase the RGB value


  • Radiators aren’t as important.

4. Riing 140mm Premium Edition by Thermaltake


Do you know what 2-way fans are? Thermaltake Riing 140mm premium Edition, on the other hand, has taken the initial step toward providing innovative technologies. For functionality, 2-way addresses both sides directly. The blade system is very complicated and beyond the scope of this essay, however keep in mind that a single fan may serve as both an exhaust and an intake fan. To cater to either the input or exhaust structure, you don’t need to split them disproportionately. Simply place the fan in the case and it will function properly.

Note that a single fan may serve both functions. One side of the fan is typically unattractive, according to reports. Thermaltake has created a product that is as beautiful on both sides and can be put in any orientation.

The fans manage to make proportionally less noises than typical fans while yet maintaining enough airflow. You introduce strong winds inside the case, resulting in a significant drop in temperature, which is good to the seated components. The static pressure is enough, which aids in the fan’s stability. You may also use “Alexa” software to operate these fans. Surprisingly, both sides can have RGB enabled. As previously said, both sides may be used equally for intake and exhaust, so sit back and watch the dancing lights from the rear and front blades. This results in strong RGB lighting in the casing, which is pleasant to the eye.

The Thermaltake Riing 140mm premium Edition fans have just one drawback. They’re not cheap. A three-pack fan costs $150, which is considerably more expensive. That means a single fan will set you back $50. It does, however, make sense. You’re receiving a premium Fan-build that works from both sides, which is a feature that isn’t found in every fan-build. That is, after all, the catch.


  • Fans that are quiet
  • It’s possible to utilize it from both sides.
  • System with a lot of airflow

5. LL Series 140 RGB by Corsair


We’re at it again. Corsair is making its third appearance on our list of the top 140mm case fans. What conclusions can we draw from this? If you’re searching for performance, the Corsair LL Series is the way to go. The Corsair LL series 140 RGB, on the other hand, comes with a twin light loop that floods the case with light. These fans are heavier than other flagship versions and need 13.2 volts (+1.2-volts more), thus they’re power hungry and require robust case fittings to support their massive weight.

There are 16 distinct lightning patterns and color spectrum on the fans. You may switch between various settings by using third-party software from Corsair or by fiddling with the BIOS. It’s all up to you. The 140mm size offers you the advantage of being able to adjust fan speeds between 600 and 1300 RPM. Surprisingly, noise levels are lower than the average of 25.0 decibels. It’s worth noting that these fans provide excellent airflow, which lowers the high temperatures in a matter of minutes. Even the static pressure generated by the fans is consistent and reasonable. Another feature of the Corsair LL series 140 RGB is the use of bearings to reduce vibration pulses.

An RGB hub and controller are included with the fans. Connect the RGB 3-pins to the hub, and the four pins to the motherboard or Molex. The remainder of the tweaking may be done using the controller or the program. The only drawback to purchasing these fans is the expensive cost. It’s even more costly than the premium version of the Thermaltake Riing 140mm. The complete package costs approximately $95 to get. So it’s all up to you.


  • Fans that are rather silent
  • High CFM

Noctua NF-A14 iPPC-3000, Noctua NF-A14 iPPC-3000, Noctua NF


Noctua, welcome back! What can we anticipate from Noctua in the future? Regardless of drab color schemes and color spectra, Noctua has been firmly planted in the earth. The Noctua NF-A14 iPPC-3000 is a high-speed fan with plenty of airflow. Users have reported that the 158.5 CFM, which is the highest on the list, resulted in a considerable decrease in temperature. Consider how fast the fans are whirling. It has acoustic acceleration characteristics and is well-optimized. It has great entry protection and can keep its lifeline intact for a longer length of time without breaking it.

To operate, the fan needs 12 volts. It’s worth noting that the fans can spin up to 3000 RPM, which is far faster than the majority of the fans on the list. The 4-pin connection is used to switch on the fans, thus you only need one connector. No RGB, which is very obvious with Noctua. They don’t give a damn about aesthetics or illumination.

Surprisingly, the ruggedized fiberglass on the fans aids in dust and water protection. It also houses SSO2 bearings with a life expectancy of over 150,000 hours. The device also comes with a six-year guarantee. Furthermore, the usage of polyamides has made the blades and material more brittle and tougher. So, yes, you can count on them to endure extreme heat. But, due to the ferocious gusts of wind sent inside the container by the fans, I doubt they will ever feel it.

Overall, if you want mid-range fans, the Noctua NF-A14 iPPC-3000 is the fan for you. Purchase them right now!


  • When the weather is hot, it’s the ideal time to use it.
  • Airflow and static pressure are exceptional.


  • There is no RGB solution.
  • High amounts of noise

7. PWM PST Arctic F14 F14 F14 F14 F14 F14 F14 F14 F


It’s time to add a fresh name to the list of the finest 140mm case fans. The Arctic is renowned for generating a variety of thermal pastes, with the majority of them aiming to offer cooling solutions. They began producing Arctic Fans, and one of them is the Arctic F14 PWM PST. With ultra-fast-moving fans and prolonged performance rates, it provides regulated PWM technology. The product’s unique feature is that it has a 4-pin connection that can be inserted in two different ways. If one of them does not suit your needs, you may always try the other.

The PWM speed controls the majority of the fan’s operation, resulting in precise input through sensors. The fans come with certain transistors and sensors. When the temperature rises, the fans begin to rotate at their maximum speed in order to cool the room. These fans operate in passive cooling mode, which means they won’t turn on until temperatures reach a certain level. All of this is due to the PWM technology utilized in the fans. The highest noise level generated is 0.3 sone, or 26.0 decibels. Not to add, these fans are built using cutting-edge technology to reduce noise levels, ensuring that you will hear little to no noise when gaming. Surprisingly, the fans feature a fluid dynamic bearing that allows them to maintain their specified lifespan. These are the supporters you should be cheering for if you’re searching for something out of the ordinary.


  • Low amounts of noise
  • Installation with two-way communication
  • Bearings with a fluid dynamic motion


  • Cooling with a single fan
  • At low system loads, it is inefficient.

Noctua NF-P14s redux 1500, Noctua NF-P14s redux 1500, Noctua NF


Isn’t this their third entry? In the first place, it’s not really unexpected. For their performance charts, Noctua is all over the place. The Noctua NF-P14s redux 1500 adds a new element to the game. The fans’ square frames enable them to double as radiators. The cooling system is of the highest quality. You get strong breezes that meander within the casing without interfering with the components. It’s also worth noting that it’s a PWM fan that operates in passive cooling mode. As a result, the fans will not turn on until the temperature rises over a specific point.

With a 4-pin header, you can make them operate on 12V. This implies you’ll have no RGB choices. There are no LEDs on these fans. It’s OK to use fans that aren’t RGB as long as they lower the temperature. Performance should be your first goal, which these high-end rotating fans can easily provide. When compared to other flagship models, the maximum noise level is 25.8 decibels, which is quite low.

This is one of the cheapest fans you can get without sacrificing your system’s performance ratio. If you believe you’ll be able to tolerate the fans’ eerie design, go ahead and purchase them now!


  • Cheap
  • A large number of optional attachments are available.


  • Can only run on a restricted number of CPUs (as a radiator)
  • At times, it may be very loud.

What are the many characteristics of a fan?

Levels of Noise

The noise levels are measured in decibels (dB), and they differ from one fan to the next. The noise level rating on the fan is always mentioned by the manufacturer, so the customer was at least aware of the consequences of operating the fans in the system. The ratings go from 10 to 36 dB, and any number higher than that just indicates you’re giving up for allowing the jets to fly about your space. However, there is a cost here. Fans perform at their best when there is a lot of noise, whereas they perform at their worst when there isn’t a lot of noise. Before you buy the fans, you need to establish a happy medium.


It’s best to go with larger fans since if your computer is under a lot of stress, you’ll require a precise ventilation system within the case. That’s only feasible if you choose the appropriate size. The sizes are typically 80mm, 100mm, 120mm, 140mm, and 200mm, although they may vary from one manufacturer to the next. You’ll have to pick between two alternatives for this. To fit additional fans, you’ll need to select the smallest size available. If you’re hoping for a larger crowd, you’ll only be able to accommodate a few people. It’s all up to you.


 CFM (Cubic Feet per Minute) is used to measure airflow, and it varies from product to product. When you install case fans, you’re looking forward to getting warm and hot air out of your system. You don’t have to worry about sacrificing your components as long as the CFM is greater. The printed CFM rate may readily be found in manuals and instructions. After reading it, make your final decision.

Fans with a Static Pressure

Inside the casing, static pressure is known for causing violent winds. Your components are in excellent hands as long as the fans are supplying them with adequate air. You must ensure that the fans you purchase have adequate static pressure ratings.           

Final Opinion

Your main focus should be striking a balance between performance and pricing. It has been observed that few costly fans provide effective effects, leaving you with nothing but financial losses. I’d suggest the Corsair Air Series AF140 since it’s one of those fans that doesn’t cost a lot yet delivers greater performance. If you want something that comes out of the box and has the greatest airflow system, the Noctua NF-A14 PWM should be your best option. Because it’s one of those fans that can produce 100 CFM or more, which is very impressive. Overall, the final choice is yours to make. Before making a choice, keep everything in mind.

I hope this tutorial has answered all of your questions!

Most Commonly Asked Questions

What is the best fan size?

It’s all about fluid dynamics. A 120mm fan should feel like it’s moving a lot of air, but this isn’t the case. Because the space is smaller, the concentration area shrinks dramatically, giving the impression that the fans are blowing more air within. When using a 200mm or 140mm fan, the air is spread out, giving the impression of less air being pushed in. The fluid dynamics are unchanged.

For a case fan, what is a reasonable RPM?

At 1000 RPM, fans are typically silent. Any RPM between 1300 and 1500 is OK. If your fans are intended to spin at 2000 or 3000 RPM, expect them to obstruct your hearing.

Are two case fans sufficient?

Certainly not! It is completely dependent on the system’s environment. If your system has components that are quite hot, you will need proper airflow control. And putting 4-5 fans in the case is the only way to accomplish this.

Case fans are among the most important cooling system components in a computer. They are responsible for carrying heat out of the computer, thus making it cool enough for you to actually work with. However, not all fans are created equal. There are many popular options with many different features, but if you are looking for the best in class case fan, you need to look no further than the newly launched Noctua NF-A14 140mm case fan..
