10 Best 120mm Case Fans Reviews in 2024

No matter how powerful a gaming computer you have, it’ll suffer to deliver you optimal performance if it’s overheating every time you start playing games or do any other heavy task. To correct that, it’s highly important that your PC rig should have good airflow to blow out the excess heat.

Hence, installing case fans is one of the most affordable ways to keep the temperatures of your gaming PC maintained. That being said, in this article, you will find some of the best 120mm case fans that you can get from the market. So, if you are interested in buying one, make sure to check these few important things beforehand:

  • Fan Speed: For faster and more efficient cooling, you should be looking out for a case fan that runs at a decent speed. For that, you can simply check the maximum speed of any case fan option as it’s generally given in the terms of RPM. A fan with a higher RPM rating will rotate fast as compared to a fan that has a low RPM rating.
  • Noise Level: While you lookout for a fast-running fan, don’t forget to check its noise levels. Generally, fast fans produce more sound which might feel unpleasant and disturbing while you work on your PC. The noise level of a case fan is generally mentioned in terms of decibels (dB). So, you should note that a case fan with a lower dB will work more quietly.
  • Airflow: The rate at which your PC is cooled down by the case fans depends on the efficiency of the case fans. With case fans that offer high airflow, the air is drawn out or sucked in faster which helps in maintaining the temperatures more easily. That said, the airflow of case fans is usually given in terms of CFM, you can compare that between multiple options to find the best one for your PC case.

Apart from these things, if you are curious to know more about 120mm case fans, we have also included a short and simple buying guide later in this article that will help you out. The buying guide includes all the essential information that a customer should care about checking before spending their hard-earned money.

Buying Guide for the Best 120mm Case Fans

Every PC owner understands very well how important it is to have a well-ventilated PC case. In case the PC has bad airflow, it will eventually lead all the components like GPU, CPU to heat up a lot when used for longer sessions. And, overheating of these kinds of components is not a good sign.

That being said, you should make your PC as ventilated as possible to keep the temperatures under control as it will increase the overall life of your PC. You can simply do it by installing case fans in your PC rig. Thus, if you are thinking of buying some new case fans for your PC, here are some things that every customer should keep in mind to buy the best case fans for their PC rig.

1. Max Rotational Speed

First of all, if you look into the market, you will come across hundreds of 120mm case fan options to choose from. However, you should note that not all of them work the same. So, the best and easiest way to compare them is by checking their max rotational speed. The speed of a fan is measured in RPM which is also called rotations per minute. Hence, it should be pretty clear to you that a fan with higher RPM will work faster and will offer better airflow. Any fan option that is able to deliver rotational speed over 1200 RPM can be considered good.

2. Noise Level

Although we suggest you go for a fast speed fan, you must take care of the fact that it’s not too noisy. Generally, if a fan’s speed is high, it is assumed to create more noise. And, from our personal experience, we can tell that the noisy fans do not offer a pleasant experience.

That’s where the build quality and the design of the fan come into play as a well-designed fan can definitely perform quietly without lacking any speed. The noise level of a case fan is usually mentioned in terms of decibels (dB). Hence, if you want to compare different options, you can easily do it as a case fan with a lower dB noise level will perform more quietly. Thus, you should go for a fan that is fast, but also quiet as well.

3. Airflow

Another important thing that you can consider checking is the amount of air displacement that the fans offer. The Airflow offered by case fans is generally mentioned in terms of CFM. Thus, a fan with a higher CFM capacity will have more power and displace more air from your computer’s cabinet. For instance, a 40 CFM fan will not perform as well as a fan that offers 60 CFM airflow. But, you must note that a fan with higher airflow capacity will have a faster speed as well which can become one reason for it to be loud and noisy.

4. RGB Lighting

Although fans are used to maintain the temperature levels inside the PC rig. However, if you think of it in another direction, case fans can also be used to decorate a PC rig as well. In the market, there are case fan options available that come with in-build RGB lighting as well. Thus, if you are a fan of RGB lighting, like most other gamers, you will definitely like those options. However, the addition of RGB lighting in a case fan increases its power usage, as well as hikes up its cost too. Thus, these kinds of case fans fall into the premium category and would be slightly pricier than other case fan options.

5. Connector Type

While buying a new case fan, you have to keep an eye on the type of connector that they use. Well, some case fans generally use a 3 pin connector, while there are such options available too that use a 4 pin connector. In general, a 3 pin connector is used for case fans. However, a 4 pin connector case fan is more advanced as the 4th pin allows your computer to adjust the fan speed as per the requirements. That means, your computer can manage the speed according to the situation which can make your computer highly power-efficient and also increase the overall life of the case fan.

6. Warranty

Apart from all the specifications, one must also not forget to check for the warranty information of the case fan. If we look at the top brands, almost all of them offer a 1-year warranty for their case fan options. Thus, it is highly important to pick a case fan from a popular brand only so that you can get the benefits of the warranty. It is due to the fact that even if the fans go faulty after a few months of usage, or come damaged out of the box, you can get a new one as a replacement without spending any extra money on it.

FAQs about 120mm Case Fans

1. How is a 4 pin connector different from a 3 pin connector?

Ans. A 4-pin PWM connector is much more advanced as compared to a 3 pin PWM connector as it adds the functionality to control the fan rotational speed. In the case of the 3 pin PWM connector, the case fan will keep running at a constant speed. On the other hand, case fans with 4 pin connectors are fully controllable and their RPMs can be adjusted as required.

2. What is the best size for a case fan?

Ans. The 120mm case fans are typically the standard and the best size as they are universally compatible with almost all kinds of PC rigs. Although, if you have other plans in mind, there are case fans of other sizes also available in the market such as 80mm, 92mm, 140mm, and even 200mm.

3. How fast should a case fan be?

Ans. It depends on what type of tasks you do on your PC. If you are a gamer or do other heavy tasks like video editing on a regular basis, 1400-1600 RPM fans will deliver optimal cooling. On the other hand, if you are a casual user and just use your computer for light tasks, fans with 900-1200 RPM fan speed will do good enough.


We have tried to include all sorts of case fan options in our list so that everyone can find a suitable one as per their taste. Thus, we hope you have gone through the article and have already picked the best one for yourself. However, if you haven’t been able to decide yet, you can also consider going through the buying guide as it contains a lot of information that might help you out.
