Cooling Capability

As the name indicates, cooling capacity is one of the most important features that you may be looking for in your best case fans intentionally or unintentionally. The fan must be able to quickly cool down your PC by dissipating heat energy from your gaming system.

The product with the highest cooling capacity will obviously rank on top of your list of buying the best case fan. Therefore it should be able to reduce the temperatures of your system by a long shot with its effective cooling skills.

The cooling capability of the case fan is greatly affected by the airflow of that model. You can say that the cooling capacity is somewhat directly proportional to the airflow and vice versa.

The airflow is usually measured in terms of CFM which is what you should check first while buying a product. Think as Low CFM means lower airflow which means lower cooling properties and higher CFM means higher airflow which will ultimately have a greater cooling effect.

Durability

When you buy a product with your hard-earned money, you want it to work well for a longer period of time. This simply means that if you’re investing in best case fans for your gaming PC, it must be durable and have a longer lifespan.

Bearing Type

The durability depends upon bearing type more than any other materials used in the product. The particular type of bearing used in the fan greatly affects its performance as well as its lifespan. The parts usually get damaged due to continuous usage and heated temperatures.

Make sure to check the bearing when buying the best case fan for your gaming computer. Some bearings can last longer than the other types. For example, the fans with fluid bearings are observed to work well for longer periods of time as compared to the ones that have a ball bearing because of less friction.

Noise Level

It is very common for case fans to be noisy and overly loud irrespective of the purpose for which the device is being used. For example, if you’re using a case fan with your PC, its main goal should not only be limited to providing a great cooling effect to the heated system but also a quiet sound environment is necessary to have a better gaming experience.

While gaming on your PC, you need to concentrate on winning the game, and if not winning, you definitely wish to enjoy the game to its fullest at the very least for which you need to focus your attention on the game. But due to the high noise coming from the case fans, focusing on the game is next to impossible.

The noise levels are usually measured in dBA which will always be given in the column of features by the manufacturer. The lower the noise level, the better will be your gaming experience.

Zero Interreptions

The noise profile of the case fans can be a great disturbance for the gamers. Therefore, in order to ensure uninterrupted better gameplay, you need to make sure that the fans you are buying must have a low noise profile so you don’t have to deal with the disturbing noise problems.

The products that we have picked for your gaming units are capable of keeping the noise profile very low and even inaudible in most cases. You will be provided with the quietest possible fan functioning greatly in cooling down your system as well.

The noise level is also affected by the rotations per minute at which the fan spins. Running your case fan at high speeds all the time will cause it to make more noise and it may get damaged soon.
