Factors to Consider While Buying the Best 140mm Case Fan

1. Airflow 

While buying any case fan, you must check the pc case airflow. Airflow is how much air that the fan can blow into the case. Airflow is mainly measured in CFM (cubic feet per minute). Therefore, you want to make sure that you get a case fan with maximum airflow while at the same time one with minimal noise levels.

Mostly the airflow of a fan will vary depending on the design, fan blade type, and speed. Fans with the best air flow are more efficient and will push air through easily.

2. Fan Speed (RPM)

It would be best to look at how fast or slow the fan rotates, which is the fan speed. The speed is measured in revolutions per minute or RPM. Low RPMs will push air slowly, while high RPMs will make the fan blades push air faster.

Most fan cases will are designed to allow blade speed increment this way, and you can use the fan at low or moderate speeds, which will help regulate the temperature. Most PWM fans or pulse width modulated fans, the revolutions per minute are managed by the input current. The best 140mm case fans are mostly designed to offer great performance at RPM ranging from 500 to 2000 RPMs.

3. Static Pressure

Static Pressure is a very important factor to consider because it is the force that the fan is throwing the air in the case while the airflow is the amount of air that the fan pushes. You will need to purchase a static pressure fan that has high pressure. You could use the high static pressure for the cooler to drive air through the fins, and you could also use it for the cases.

The static pressure is measured in mmH2O. The high static pressure fans will ensure that air is received in all components, and it o ensures that there is efficient cooling.

4. Noise Level

Another aspect that you can think about is the noise level of the 140mm case fans you will purchase. Of course, all case fans are noisy, but the noise levels will vary depending on the brand and construction of the case fan. The noise of the case fan is mostly measured using the Decibel (dB), which normally goes between 10 to 35 dB.

Top speed case fans will be louder than the ones with low fan speed. Some brands will design case fans with LNA or the low noise adapter that will help to reduce the noise levels.

5. Power Connection Type

You have to note how your computer's case fan will be connected to the system before purchasing the case fan you settle for. Most of the best 140mm fans have a four-pin that will typically connect to the four-pin connector on the motherboard.

However, you can also find some models that will connect to a four-pin motherboard using a three-pin. Others will also connect directly to the power supply, and some will have a combination of the three and four-pin.

6. Bearing Type 

The bearing type is another great point you should check while purchasing the 140mm case fans. Some of the best well-known bearings are; fluid dynamic bearing, which is best for reducing noise; ball bearing, which has great build quality; and sleeve bearing, which is one of the most affordable. The fluid dynamic bearing is a commonly used bearing for most of the best 140mm case fans because it has a self-lubricating feature.

7. Number of fans

It is advisable if you paid attention to the number of fans that a package comes with. Since every computer uses multiple fans, you can save some dollars if you purchase case fans that have more fans in a package. For example, the best 140mm case fan will normally come with up to five fans.

8. Fan Lighting

Case fans will come with varying lighting options, and if you want to upgrade your computer's aesthetics, you should consider investing in a fan that comes with this feature. However, it would be great if you invested in one that comes with inbuilt lightings.

Frequently Asked Questions(FAQs)

1. Do 140mm fans cool better than 120mm?

The 140 mm fans and 120mm fans have a smooth performance that makes them unique. The 120 mm fan is the most regular in almost all PCs, and they have amazing features and relatively quiet. The 140 mm, on the other hand, is considered to be more superior to the 120mm fans because they have better airflow and great noise levels.

2. Are intake and exhaust fans the same?

Intake fans are the fans on the print part of the pc, that draw cool air from the room to cool the pc. On the other hand, exhaust case fans are Fans on the rear part of your computer that expel hot air from the computer to the room.

Is it better to get 2 140mm fans or 3 120mm fans?

Having 2 140 fans or 3 120 fans will mainly depend on what you are looking for. Suppose you are looking for a great and effective cooling then, it will be better to get the 3 120 fans. However, the 2 140mm fans are much better because they are quiet and will not be as powerful as the 3 120mm fans. Conclusively it will all depend on what you are looking to get.
