Case fans form an essential part of the PC cooling system. They pull in cooler air from outside and push it away from hot spots inside the case such as the graphics card and heat sink.
It's crucial to take into consideration a few factors when shopping for a new case fan. CFM (Case Flow), power consumption, noise level, and fan controls are some of the factors you should consider when shopping for a case fan.
120mm vs 140mm Fans
The 120mm fan is usually the size that you will find in most cases. They are typically rated 40-50 CFM and can cool your CPU or graphics card. You should be aware that higher CFM results in louder noise. If you prefer a quieter option, choose the 140mm model.
Static RGB Fans
Fans with static pressure and rgb are perfect for anyone looking to upgrade their PC in a stylish way. They feature white fan blades, which add to the aesthetics of your case. The controller makes it easy to customize them for any 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. There are a variety of sizes available, so you will be able find one that suits your build.
PWM vs. non-PWM supporters
Pulse width modulated is the most common type of fan on the market. It allows for a variable speed to be used at different times. This is useful for lowering your power consumption and increasing the life of your components by reducing overheating.
PWM's downside is that it may be pricey. If you're on a budget, you can opt for non-PWM models, which are usually more affordable.
Most premium 200mm case fan models are equipped with RGB leds. This can have a dramatic effect on the appearance of your system. They're also often incredibly quiet, and can be customised to suit your colour schemes.

You'll also need the right fan if you are looking to upgrade your graphics with a video card or GPU. If you want to get the most performance from your hardware, it is a great idea to ask the manufacturer what fan they recommend.
Most cases are not built to accommodate the larger fans that you will likely need for your setup. You can get frustrated if you purchase a larger fan, only for your case to be incapable of handling it. Before buying fans, make sure you check your system's dimensions and that they are compatible with the motherboard.
