Things to Consider While Purchasing the Best 140mm Case Fans:
140mm case fans are mostly considered to be the best option when it comes to cooling performance for either a computer cabinet or CPU. With so many options and less knowledge, it becomes confusing to choose the best option. If you are wondering how to purchase the best 140mm case fan, then below is a detail guide for your reference.
1. Fan Speed (RPM)
It represents the speed of the fan rotation and measured in terms of RPM (revolutions per minute). The general rule to consider while analyzing this factor is – higher RPM means more speed and less time is taken to decrease the case’s temperature.
140mm case fans are available in different speed ratings that include 1200 RPM, 1500 RPM, 1800 RPM and many others. Though higher RPM ensures better cooling performance, it can also lead to high noise levels which is another factor to consider. If you want a silent computer, then you may have to consider the noise levels while analyzing the preferred RPM.
2. Air Flow
Expelling warm air outside and inhaling the cool air inside – is the main purpose of any 140mm case fan. And the air flow factor represents the same. It is usually measured in terms of CFM (cubic feet per minute). Apart from airflow, it also provides insights on the product’s overall performance and efficiency.
CFM further depends on the sub factors that include position of the intake part, orientation, exhaust part of the case fan and shape.
Higher the CFM, better will be the air flow. In your computer case, you may need maximum airflow circulation so that the computer components will operate better under low temperatures.
Remember that, even if the CFM is low, RPM can be high. Some of the budget-friendly 140mm case fans have lower RPM and higher CFM.
3. Power Connection Types
Before choosing 140mm case fan, you should understand how it connects to the system. In most of the cases, they use 4-pin connection type which can be easily connected to a 4-pin connector on the motherboard. Even if the case fan has a 3-pin connection type, you can still use a 4-pin connector on the motherboard. If you use a 3-pin connection type, you can connect to 4-pin connector however you have to use only three pins.
You can also find other case fans in the market that have Molex connection type. Instead of connecting to a motherboard, the molex can be directly connected to the power source. Some of the case fans also come with 2-pin, 3-pin and molex type connections.
4. Bearing Type
140mm case fans are available in different types of bearing that include sleeve, ball and hydrodynamic. Among these options, hydrodynamic bearing is considered the best and durable option as it comes with a self-lubricating feature. sleeve bearings are considered least expensive. When it comes ball bearing last stronger compared to sleeve bearing but generate a lot of noise.
5. Noise Levels
Before purchasing a 140mm case fan, you should also check out the noise levels produced by it. The noise levels are mostly represented in terms of decibels (dB). The dB count mentioned in the product specifications represent how loud the fan will be when it is running at the maximum RPM level.
Most of the 140mm case fans available in the market range between 10 to 35 dB. Louder case fans can disturb the user and also affect the experience. We recommend considering a model that provided efficient performance without generating noise.
6. Size
140mm case fans are available in different sizes that include 80mm, 120mm, 140mm and 200mm. Among them 120mm is considered the most standard size option. However, larger computer case fans are considered more efficient in terms of air flow and less noise levels. So, 140mm case fans have become quite popular as they are a combination of budget price, size and performance.
7. Number of Fans
As a computer utilizes multiple fans, it can better to purchase them as a pack to reduce the upfront costs. Most of the best 140mm case fans come in a pack of 5. Choosing this type of option can be of great value. Most of them are easy to install in any computer case.
8. Fan Lighting
Similar to most of the computer peripherals, case fans come with different lighting options. If you like to enhance your PC’s aesthetics, then you have to check the lighting choices available along with the case fan. Some of them come with RGB lighting while others come with single color LED. We recommend to check out a case fan that comes with in-built lighting so that it can look much better.
9. Fan Speed Control
The ability to tweak the fan for optimized experience is always handy. So, we recommend checking out a case fan that ensures tweaking options. You can also control the fan speed for optimizing it performance. And you can also dictate the noise level for ultimate experience.
10. Power Consumption
It represents the efficient operation of a 140mm case fans. When you compare the speed and power consumption of different fans, it is helps you find out which one offers more speed in less power consumption. Low-speed fans usually consume less power compare to higher speed fans.
However, it is not always not true that low speed fans provide less power consumption. So, it is always better to check the fan specifications and power consumption before making the choice. You should also check out the size and see if the system can handle this power.
11. Quality
All the 140mm case fans generate at least some noise. And you cannot purchase a low noise fan and expect better performance. So, if better efficiency and performance is major factor along with less noise level, then we recommend choosing advanced quality produce with enhanced features.
For example, a high-end product comes with noise reduction features. Including that, you should also check out the fan blade quality before making a purchase. Higher the blade quality, lesser will be the noise. But you may have to compromise in some part as you cannot get high RPM and low-quality fan blades.
12. Ventilation
Every system needs ventilation when installed in a room. So, you have to check whether the case comes with extra vents on the top. They let the air flow in and out of the system without compromising the efficiency.
There are several cases which offer extra vents as they need additional hardware for covering all the components. We recommend to check for a case which allows proper air flow.
13. Connector Type
The next factor to consider while purchasing a case fan is connector type. Most of the modern-day CPUs and GPUs are compatible with majority of case fans. But some case may be incompatible with the system.
For that, you have to check out whether any other connector type is suitable with your system. If the case fan is compatible with CPU, then it can be a better option. But in some of the cases, you may not use any case fans with certain connectors.
14. Fan Aesthetics
RGB lighting can be an important aspect for gamers. This is why manufacturers have been adding the case with lighting features and aesthetics. They offer eye-catching design and lighting mechanisms for attracting the customers. But you should purchase a fan that is a combination of decent performance and aesthetics.
15. Performance
For any case fan, performance is the primary factor you are investing in it. The performance of a 140mm case fan is determined using in and out airflow which is represented in terms of CFM (cubic feet per minute) rating. Higher the CFM rating and better will be the airflow. And ultimately, you will get improved performance and decreased temperatures.
16. Price
There are several 140mm case fans in the market that range from budget-friendly to expensive. You have to choose a model that comes within your budget without compromising the necessary features.
17. Warranty
When you are spending several bucks on a case fan, it is important to check out the warranty duration. And in addition to that, it helps to get better services from the manufacturer without paying any money. It is suitable to select a case fan with a longer warranty duration. One easy way to ensure this is to simply check their included warranty as computer fans offer 2 year long, 3 year long, and even 6 year warranty periods where higher is always better.

Frequently Asked Questions
Ans: When it comes to analyzing RPM of a case fan, you have to consider this thumb rule – higher the RPM, louder will be the model. A 1000RPM is actually considered pretty good as most of the case fans come between 1400 and 1600RPM. Lesser noise means non-intensive or leisure PCs
Ans: Usually, higher the case fan number, better the airflow. But we recommending choosing a case that supports at least 3 fans for optimum performance. Having more case fans will ensure proper airflow and better overall performance. If you use a computer for heavy workouts or gaming, then you may need more case fan and the other way around.
Ans: For connecting case fans, you may need a PSU with Molex connectors. You can use Molex three-pin fan adapters or plug in the fan directly like a molex connector. But the fan will run at complete speed as there would be no voltage tweaking option.
Ans: Generally, only a single case fan will be mounted at the rear end of the case. But if you are investing in a high-quality case, then it offers two or three case fins. However, it may be a bit more expensive. When you look at the bright side, it will significantly improve the performance and keep the temperature to a minimum.
Ans: Case fans are plugged into four-pin system fan heads which are located on the motherboard. They are also plugged into three-pin system fan heads based on the personal preference. But if you need more than one case fan, then you can use one of the two plugging options.
Ans: Usually, case fans last for at least 3 years. But it also depends on fan usage. If you use it daily, then the lifespan of case fan decreases drastically. However, if you are an occasional user, the case fan can be operated for a long period of time. Most of the brands mention average lifespan on their fan specifications in the product description.
Ans: For that you may have to plug the power cord of the case fan into three-pin or four-pin system fan header. After that, you can control the case fan speed in the BIOS menu. If the case fans are connected through Molex connected to the PSU, then you will not be able to control the speed.
Ans: The fan size can be determined by the fan size fitting positing in the case and measuring along the fan four sides. However, make sure the distance between the fan screw holes and the actual body. the most popular case fans have 120mm size.
Ans: The blow will be forward when the fan turns in same direction as the angled blade. However, when the angled down blade and fan turn in opposite direction, the reverse is the true answer.
Ans: You can achieve this by simple disabling the LED on the case fan and cutting the LED wire. Some of them come with jumper that can be removed while other come with power leads that can be cut. Some of the case fans come with jumpers that don’t cut the power lead to LED.
Ans: The difference between the 120mm and 140mm fans is not just cooling. The main reason for 140mm being better is the noise levels. The 140mm fan is usually larger so it can provide decent airflow at lower RPM. Smaller fans are capable of operating at higher RPM because of the small size and increased sound output.
Ans: Bigger case fans are usually much better compared to smaller ones, especially when it comes to sound output. Larger fans are capable of operating at lower RPM even with same airflow as high RPM and small sized fan. As they are operating at lower RPM, larger fans come with lower noise levels and are usually a popular choice.
Ans: In a PC case, you can place case fans anywhere you want. But it needs the case to support the location. Actually, case fans are placed at the back of chassis for dissipating the warm air. Apart from that, you can fit the case fans on the front sides or top of the chassis.
Ans: If the case fan is plugged into a three-pin or four pin system fan headers, then you can overlock the fan. Now, you have to head the BIOS menu and enter the case fan settings. Once the case fan information is found, the bIOS will display the RPM information. Higher RPM levels ensure faster revolution of the case fan.
