The amount of airflow a case fan can produce is one of its most important characteristics. CFM, or cubic feet per second (CFM), is a unit that measures the airflow through an opening. A higher CFM rating means more airflow is generated, reducing temperatures and improving performance.
Some of the most popular case fans are those that produce a good amount of airflow while being incredibly quiet. You need to consider what type of fan you want, how noisy it is, and your budget.
The Noctua NF-14 PWM 140mm fan is a great choice if you want to get the best fan for the money. It uses a PWM connector and comes with a three-year warranty. The product also has interchangeable colored corner panels making it one of most customizable on the market.
The ARCTIC F12PWM Rev.2 case fan is another option. The ARCTIC fan produces 53 FCM air flow which is a substantial amount of airflow. Despite its airflow, ARCTIC F12 fans are quite loud. The fan can be turned off by turning off the PWM function, which allows it to run at a low rate of speed.
Despite its high performance, the ARCTIC F12 has a lower noise level that most of its rivals. The noise level is below 36 dBA and can be set at a slower speed to minimize any impact on your system's performance. And, because it is designed with a PWM function, your motherboard will be able to control the speed at which the fan operates.
Silent Wings 3 is another fan that produces substantial airflow at a low price. It has a 6-pole motor but can produce over 100 square feet of airflow. This is much more than you would expect from a smaller fan. The case fan produces less noise than the ARCTIC fan.
Aside from its impressive airflow capabilities, the Silent Wings 3's features are also well-designed. This includes a focussed flow frame, which helps to concentrate airflow and reduce noise. The unit also includes eleven stator guide vanes and a six-pole motor.
The Rosewill 120mm Long Life Sleeve is the final option. It has the highest airflow volume of any top-of-the-line fans. It not only circulates air more than the rest, but it also cools the PC faster than others. Rosewill 120mm Long Life Sleeve, despite its small dimensions, has a maximum RPM value of 2000. The RGB lighting is the most striking feature of the Rosewill 120 mm Long Life Sleeve. This is not a feature you should have, but it's an awesome feature.
It doesn't matter which model you choose; you'll need some screws and a battery. Although most models include these, some may need you to connect jumpers.
