One of the most important features of any case fan is the amount of airflow it can generate. CFM is a measure of how much air flows through an opening. It is measured in cubic feet per hour (CFM). CFM rating higher means that there is more airflow. This reduces temperature and improves performance.
The most popular case fans produce great airflow and are extremely quiet. It is important to take into account the budget, type and amount of airflow.
The Noctua NF-14PWM140mm case fan is a fantastic choice if your goal is to achieve the maximum airflow. It has a PWM connector, and comes with a 3-year warranty. It also features swappable corner panels in different colors, making it one the most customizable options available.
The ARCTIC F12PWM rev.2 is another high performance case fan worth looking into. The ARCTIC fan can generate 53 FCM of airflow, which is a large amount of airflow. Despite its impressive airflow, the ARCTIC Fan F12 fan is somewhat noisy. Fortunately, the PWM function can be turned off, allowing the fan to run at a low RPM.
Despite the ARCTIC F12's high performance, it also has a lower noise level than most of its competitors. The noise level is below 36 dBA and can be set at a slower speed to minimize any impact on your system's performance. Your motherboard can control the speed of fan operation because it has a PWM feature.
Silent Wings 3 is another fan that produces substantial airflow at a low price. The Silent Wings 3 has a 6-pole motor that can deliver over 100 square inches of airflow. This is more than you would get from a smaller fan. However, the case fan doesn't produce as much noise as an ARCTIC fan.
Aside from its impressive airflow capabilities, the Silent Wings 3's features are also well-designed. The Silent Wings 3 features include a Focussed Flow Frame, which reduces noise and helps concentrate airflow. The unit also includes eleven stator guide vanes and a six-pole motor.
The Rosewill 120mm Long Life Sleeve is the final option. It is the top-rated case fan, producing the most airflow. Not only does it circulate more air than the rest, it also cools your PC faster than the rest. The Rosewill 120mm Long Life Sleeve is small in size but has a maximum RPM 2000. However, RGB lighting is the highlight of this fan's Rosewill 120mm Long Life Sleeve. While it's not an essential feature, it's still a fantastic feature.
You will need to have a few screws and a cord, regardless of which model you choose. While most models have these included, some models will need you to either connect jumpers or use an additional fan controller.
