Factors to Consider When Buying Case Fans

You might be tempted to pick up the cheapest option on the market but that is not something that we can recommend. Here are a couple of things that you need to keep in mind when you are in the market for case fans.


The size of a case fan determines how much air it can pull into the case or exhaust out of the case. They come in different sizes such as 80mm, 120mm and 140mm. 120mm is the most popular size and these fans will fit into pretty much any case that is on the market right now. The size of the fan can increase the airflow but that is a problem that can also be solved by using additional fans of the same size.

Here we are going to look into 120mm fans as they are the standard size and they can easily fit into pretty much any gaming case.


Just because the fans seem to have a boring job does not mean that they have to look boring too. There are plenty of options when it comes to aesthetics. You can match the color of the fans with the rest of your build. You can have fans that come with LED lights.

Nowadays fans come with RGB lights that can be controlled to offer all kinds of different effects. If other components of your build have RGB lighting then you could get RGB fans to match the theme of your build.


Many case fans that offer higher RPM (revolution per minute) produce noise. While there are fans on the market that are silent as compared to others, you will need to make a trade-off between fan speed and noise. The faster the fans spin the more noise they will make. If you would rather have a silent system, then you should opt for the fans that are quieter.


The speed of a fan is measured in RPM. RPM stands for revolutions per second. While a high-speed fan will provide better airflow, it will also produce additional noise. What you need is a balance between the two. A fan that offers decent speeds but does not produce a lot of noise.


Case fans use different types of bearings. Each type has its pros and cons. Here we are going to look into the different types of bearings used in case fans so that you have a basic understanding of what you are buying.

Sleeve Bearing

Case fans that use sleeve bearing are normally inexpensive. That is one of the reasons why they are so popular. While these are cheaper than other types of fans they are also not as durable. They will last a year or two.

Ball Bearing

Ball bearings are found in high-end fans. These fans offer high airflow and are expensive because they are more durable and produce less noise.

Rifle Bearing

In simple terms, fans that use rifle bearings are better than sleeve bearing fans but not as good as ball-bearing fans.
