10 Best Case Fans of 2019

Posted on

If you are a PC user, you will probably know the importance of maintaining a reasonable and safe temperature of important components to keep them functioning efficiently. However, there are instances where certain types of PC usage or usage of the PC in a certain environmental condition can lead to overheating of the CPU case.

If you are facing such overheating issues, then it may be time for you to place one or two case fans that can disperse away the excess heat. After all, you don’t want to shorten the lifespan of your valuable equipment simply because of overheating.

Using a case fan is considered as active cooling in the PC maintenance parlance. The main role of a case fan is to push away the hot air from areas like the heat sink and graphic cards, and pull in cooler air from the outside and allow it to flow over the “problem” areas.

Choosing the right fan

There are a few factors which you should consider as you research various case fan options. Having knowledge of such factors will allow you to sift through multiple offerings and short-list a select few which you can then evaluate more closely.

Purpose of the fan

You need to know the reason as to why you are looking for a case fan. Is it because your existing fan is making too much noise? Or is it because you need active cooling in a specific area of the CPU?

If you are simply taking a preventive step of protecting the entire CPU system, then the choice of your fan will be different. Knowing the purpose of you wanting a case fan will point you in the right direction.

Ability to control the settings

Some applications of the fan would simply require a plug-and-play model which runs at the same speed as long as it is powered. Some other applications may require a fan to run at variable speeds in different time periods.

The ability to control the fan either manually via a controller or electronically through software is an important factor. This factor is related to our first point, which is the purpose of the fan. Once you know the purpose, you will know how much controlling ability you need for your case fan.


The noise level of the fan is measured in dBA or decibels. The decibel level is measured for the highest speed of fan operation. It is an indication of how loud the case fan is.

It generally is a good idea to have a look at the dBA level but you must also note that the dBA level is not always consistent. There are ways, especially through physical adapters and third-party software, in which one can lower the noise level by slowing down the speed of the fan.

However, dBA is still a reasonably good benchmark to determine the noise efficiency of a fan’s design.

Fan Speed

Fan speed is measured in revolutions per minute. It an important performance attribute of any case fan. Depending on your heat dissipation requirement, you need a fan with a speed that is high enough to dissipate component heat.

However, selecting a fan with the right speed is a balancing act. While higher speeds are great as they can blow away heat faster, they also make more noise. You can, however, lower the noise by opting for a larger fan which will run at a lower speed and still provide enough air flow to dissipate the same amount of heat.

Size of the fan

The size of the fan is perhaps one of the most important metrics when selecting a case fan. There is a wide range of sizes, from as low as 40mm to as high as 200mm, available in the market.

Fan size is important because a larger fan can provide the same amount of air flow at lower speeds as a smaller fan at a higher speed. Since the smaller fan has smaller blades, it has to rotate faster to generate a high enough air flow.

The other size to think about is the overall dimensions of the case fan module. After all, it has to fit within your CPU system. Depending on how you plan to use the case fan and where you plan to place it, dimensions will play an important role.

Generally speaking, most CPU cases are able to accommodate 120mm and 140mm models. The 120mm models are the most popular.


The pins on the case fan module primarily provides power to the module. However, the pins can also provide the added ability to control the fan settings. A standard 3-pin design will provide power to the fan and allow it to run at a constant speed. The speed in a 3-pin design can be lowered by lowering the voltage coming out of the motherboard.

Some fans have a 4-pin design. This configuration allows the use of third-party software to control the speed of the fan and reduce energy costs. Fine-tuning of the fan speed also helps reduce the noise levels.

There is also a 2-pin configuration on some case fan models. That setup is very basic and it simply allows on and off functioning with no control over fan speeds.


The look of the case fan can be an important factor for some users. Some fans come with LED lighting. In such cases, some users may prefer the color and the design of the lighting to match the overall look of the computer system.

There are components like the mouse, keyboard, screen, and the CPU housing which may already have a certain theme or look. The idea is to select a fan or an LED lighting range which does not look out of place or attract the wrong kind of attention.

Let us now look at some of the best fans across different size categories.

80mm Case Fans

1. Arctic F8 PWM REV. 2

Arctic F8 PWM REV. 2

Budget buyers will like the Arctic F8 PWN REV. 2. It costs a mere $5.99. For this small price, you get a case fan with a 2-way design that blows warm air out and pulls cooler air in. What’s amazing is that this budget fan has a 4-pin design which allows you to control the operation of the fan via a controller or third-party software.

Being an 80mm fan, it will run at high speeds. Hence, it will need lubricating oil for smooth rotations. The fan has an integrated capsule with lubricating oil in it for that very purpose. Decent levels of lubrication will also help lower the noise levels of the fan.

Other fans in this category use a sleeve bearing for noise reduction. However, that design does not provide as long a service life as the Arctic F8 PWM REV. 2 does with an integrated lubricating oil capsule.

While the 80mm Arctic F8 PWM REV. 2 is small enough to fit in small CPU housings, it may be too small in size for a medium or large CPU system. It might not be able to dissipate the heat or provide an adequate amount of airflow for larger systems.
