Case fans form an essential part of the PC cooling system. They draw cooler air into the case from the exterior and push it to hot areas such as the graphic card and heatsink.
Consider a few important factors before purchasing a case-fan. These include CFM (Case Fan Flow), RPM, power consumption, noise levels, and fan control options.
120mm vs 140mm Fans
Most cases use the 120mm case fan. The 120mm fans have a rating of 40-50 CFM. That's more than enough for your CPU and graphics. You should be aware that higher CFM results in louder noise. If you prefer a quieter option, choose the 140mm model.
Static RGB Fans
If you want to add a stylish touch to your PC, static-pressure rgb Fans are the perfect choice. The white blades add to the aesthetics. These fans come with a control panel, making it easy to change the color scheme.

The best thing about them is that they can be used to get a large amount of RGB lighting, without having to worry about connecting multiple cables. The fans are available in various sizes so you can find the perfect fan for your system.
PWM fans vs non-PWM fans
Pulsewidth Modulated technology is used by most of the case fans available on the market. This technology allows them run at different speeds during various periods. It is a great way to reduce your power consumption, and increase the life of your components.
PWM can be costly. If you're on a budget, you can opt for non-PWM models, which are usually more affordable.
Many of the most expensive 200mm fans come with RGB LEDs. These can dramatically improve the look of a system. Many of them are also incredibly quiet and can be tailored to your preferred colour scheme.
We have gathered some of best static pressure RGB fans that you can check out. All of them are rated for high airflow, low noise and make excellent choices for cooling your PC.

Case fans are an important component in any high-end system. The fan should be suited to the user's needs and durable for many years.
For example, if you're looking to improve your graphical performance with a new video card or GPU, you'll need a fan that is designed for the job. It can also be a good idea to check the manufacturer's recommendations for the best fan for your system, as it will help you avoid unnecessary expenditure and get the most out of your hardware.
The biggest issue with a lot of cases is that they're not designed to accept the bigger fans you'll likely need in your setup. It's a pain to buy a larger-sized fan only to realize that your case can't handle it. Before buying fans, make sure you check your system's dimensions and that they are compatible with the motherboard.
