The power and speed of several computer parts, including RAM, graphics cards, and processors, have improved. The system now produces a significant quantity of heat as a result of this. Such components could not function as well if they are not properly cooled. In an effort to return the temperatures to normal, the motherboard may throttle.

A case fan is essential since it can remove the extra heat from the case. Investing in a quality case fan will let you enjoy your computer’s components for a long time and end up saving you money. Although the 120mm case fan is still available, it is not the best for pushing a lot of air out. By selecting the best case fan, such as the 140mm, the heat may be dissipated more quickly, protecting the internal components.

An excellent case fan with a size of 140mm is recommended if you enjoy video editing, 3D animation, or gaming. These case fans are effective and move a lot of air at low speeds since they have bigger blades. A good case fan will also operate quietly for you.

Things to Consider While Purchasing the Best 140mm Case Fans:

The optimum choice when it comes to cooling performance for either a computer cabinet or CPU is typically thought to be a 140mm case fan. Choosing the best option gets difficult when there are so many possibilities and so little expertise. Here is a comprehensive buying guide for the finest 140mm case fan if you have any questions.

Air Flow

Any 140mm case fan’s primary function is to exhaust warm air to the outside while drawing in cool air from within. The airflow factor also indicates the same. Typically, it is expressed in terms of CFM (cubic feet per minute). In addition to airflow, it offers information on the overall effectiveness and efficiency of the device.

The position of the intake section, the orientation, the exhaust part of the case fan, and the shape of the fan are other subfactors that affect CFM.

The airflow will be better the higher the CFM. In order for the computer components to function more effectively in cold conditions, your computer casing may require the maximum amount of airflow circulation.

Keep in mind that RPM might be high even if CFM is low. Some of the more affordable 140mm case fans feature a higher CFM and lower RPM.

Fan Speed (RPM)

It represents the fan’s rotational speed and is expressed in RPM (revolutions per minute). Higher RPM indicates faster speed and requires less time to lower the case’s temperature, according to the general rule to be taken into account while studying this element.

There are numerous various speed ratings for 140mm case fans, including 1200 RPM, 1500 RPM, and 1800 RPM. Although greater RPM guarantees better cooling effectiveness, it can also produce loud noises, which is another thing to take into account. If you desire a silent PC, you might have to analyze the preferred RPM while taking into account the noise levels.

Power Connection Types

You should comprehend how a 140mm case fan links to the system before making your choice. They often employ a 4-pin connection type, which is simple to attach to a 4-pin motherboard connector. You can still use a 4-pin connector on the motherboard even if the case fan has a 3-pin connection type. When connecting to a 4-pin connector using a 3-pin connection type, just three pins are required.

Other case fans with a Molex connector style are also available on the market. The Molex connector can be directly linked to the power source rather than via a motherboard. Additionally, certain case fans feature 2-pin, 3-pin, and Molex connections.

Noise Levels

You should also consider how loud a 140mm case fan will be before you buy one. The most common unit of measurement for noise levels is decibels (dB). When the fan is spinning at its highest RPM, it will be as loud as indicated by the dB count in the product specifications.

The majority of the 140mm case fans on the market range in volume from 10 to 35 dB. Louder case fans may annoy the user and have an adverse effect. We advise taking into account a model that performed effectively without producing noise.

Bearing Type

There are several bearing options for 140mm case fans, including sleeve, ball, and hydrodynamic. Because it has a self-lubricating function, the hydrodynamic bearing is regarded as the most reliable and long-lasting alternative among these. The least expensive bearings are sleeves. Ball bearings are more durable than sleeve bearings, but they also make more noise.


Case fans come in a variety of sizes, including 80mm, 120mm, 140mm, and 200mm. Among them, 120mm is regarded as the most common size choice. Larger computer case fans, however, are thought to be more effective in terms of airflow and noise levels. As a result, 140mm case fans are quite popular since they offer a good balance of performance, size, and affordability.

Number of Fans

As a computer uses several fans, it may be better to buy them all at once to save money. The majority of the top 140mm case fans are sold in packs of 5. Selecting this kind of alternative might be quite beneficial. The majority of them are simple to install in any type of computer casing.

Fan Lighting

The majority of computer accessories, including case fans, offer a variety of lighting options. Check out the lighting options as well as the case fan if you want to improve the appearance of your PC. While some of them include RGB lighting, others only have single-color LEDs. We advise looking into a case fan with built-in lighting so that it can look nicer.

Fan Speed Control

It’s always useful to have the option to adjust the fan for the best performance. Therefore, we advise looking into a case fan with adjustable settings. The fan speed can also be adjusted to improve performance. And for the best experience, you may also control the noise level.

Power Consumption

It displays how effectively a 140mm case fan operates. It is easier to determine which fan offers more speed at a lower power consumption when you compare the speed and power consumption of various fans. In general, low-speed fans use less energy than high-speed fans.

Low-speed fans do not necessarily consume less electricity, while this is not always the case. Therefore, before making a decision, it is always preferable to check the fan specs and power consumption. Check the size as well to verify if the system can manage this power.


When a system is installed in a space, ventilation is required. Therefore, you need to make sure the case has additional top vents. They allowed air to enter and exit the system while maintaining efficiency.

Many cases come with extra vents since they require extra hardware to cover all the components. We advise looking for a case that allows for optimum airflow.


At least some noise is produced by each of the 140mm case fans. Additionally, you cannot expect a superior performance by purchasing a low-noise fan. So, if more efficiency and performance, along with lower noise levels, are important considerations, we advise selecting advanced quality produce with expanded characteristics.

A high-end product might have noise reduction features, for instance. Along with that, before making a purchase, you should evaluate the quality of the fan blades. The noise level will decrease as blade quality increases. However, you might need to make some concessions because you can’t purchase low-quality fan blades with a high RPM.

Connector Type

The type of connector should be taken into account next when buying a case fan. The majority of case fans are compatible with the majority of contemporary CPUs and GPUs. However, some situations might not work with the system.

To do it, you must determine whether your system can use any other connector type. A better choice may be made if the case fan is compatible with the CPU. However, under some circumstances, you might be unable to use any case fans with specific connectors.

Fan Aesthetics

For gamers, RGB lighting can be a crucial component. Manufacturers have been including cases with lighting features and aesthetics because of this. To draw in customers, they provide eye-catching design and lighting features. However, you ought to buy a fan that combines good looks with good performance.


Performance is the main consideration when purchasing any case fan. Utilizing the in- and outgoing airflow, which is measured in terms of CFM (cubic feet per minute) rating, the performance of a 140mm case fan is established. The airflow will be better the higher the CFM rating. Finally, you will experience better performance and lower temperatures.


When purchasing a case fan for a significant amount of money, it is crucial to consider the warranty period. Additionally, it is beneficial to have improved services from the manufacturer without having to spend any money. A case fan with a longer warranty period is a good choice. Checking their included warranty is one simple method to make sure of this since computer fans typically come with 2-year, 3-year, or even 6-year warranties, with longer warranties being preferable.

How to Clean 140mm Case Fans?
