I know it is hard to narrow down your search from the hundreds of 140mm case fans present in the market. So I advise you to look for the factors that I have given below and pick the one that ticks the list of factors.

Fan Size

First of all, you should know that the bigger the fan, the more efficient it is . Be careful though, that doesn't mean that a smaller fan won't give you good results. Indeed, the quality of manufacture also comes into play.

Either way, today's PC cases will accept most 80mm , 120mm, and 140mm fans . These measurements represent the base of the fan or, in other words, the square of the fan. It comes from 25mm to 250mm. But choosing the 140mm is an ideal option. The reason is that its large blades. These large blades are sufficient enough to circulate more air at low speed. In terms of noise, these are less noisy. 

Number of fans

Your system needs multiple fans to keep it cooler. That said, instead of buying multiple fans and wasting money, you can buy a fan case that has multiple fans in it. Also, the fan pack comes with the added advantage of easy installation in your computer case as well. So look for a fan case that consists of 5 fans in it. 

Fan speed

It is crucial to test the fan speed because your speed tells you how well it performs. Also, the size of the fan influences the speed. 

Speed is measured in RPM, which is revolutions per minute. A large case fan with lower RPM is highly suggested because it can circulate air and operate with less noise than a small case fan. 

Noise levels

Nobody wants a noisy case fan. When the 140mm case runs/works at maximum RPM, it makes noise. Usually, the small case fans tend to make more noise than the large ones. But still, the noise levels of most 140mm case fans that range from 10dB to 35dB are acceptable. 

Fan type

Apart from the size, the case fans also differ in type. There are two types, static pressure fans, and airflow fans. Airflow fans are ideal for cooling processes, whereas static pressure fans are ideal to use with water cooling radiators. 

Power connection type

Before you pay for the 140mm case fan, you must find out how to connect it to your system. Most case fans have a 4-pin connector type, and it simply connects with your 4-pin connector motherboard. Your system with a 4-pin type can also support a case fan with a 3-pin type with a Molex plug included. But when it comes to which is best? The 4-pin type connector case fan is easy to use and offers better fan speed control.


So now you’ve got a pretty good idea of what to expect when you’re shopping for some of the best 140mm case fans. Remember to keep an eye out for what you want out of your setup - are you looking for fans that will provide functionality, or do you also want a pop of color to impress your gamer friends while you’re streaming? Most of the fans on this list are really affordable, so there should be something here for everyone!


Are 140mm fans better than 120mm?

When compared to 140mm fans, 120mm fans are seen as a standard one in most PCs because they are equipped with some good features. But still, 140mm fans offer a sleek performance than 120mm and beats the former with a better noise level and airflow. 

Are bigger case fans better?

In general, bigger fans will move the same amount of air the smaller fans do at lower revolutions per minute. Since the electric motor present in the bigger fan mechanism doesn't have the need to spin fast, the bigger case fans are quieter than smaller ones.

How many fans do you need in a PC case?

Keeping your system cool is very important. So I recommend you to buy a PC fan case with at least three fans without the power supply, and GPU fans are taken into consideration.
