Best 140mm Case Fans: 5 Top Picks In 2020

If you’re an avid gamer, a video editor or simply a tech enthusiast, you’re likely familiar with how important cooling is for your whole setup. A ton of importance is placed on temperature and cooling solutions, whether you’re discussing a GPU cooler, CPU cooler, a water cooler or a set of custom airflow coolers. All of them are essential to keep your PC running smoothly and efficiently.

While GPU coolers and CPU coolers are often the focal point of a cooling system, the case may retain a lot of heat and its ventilation may not be enough to dissipate heat on its own. This is where case fans come in. They manage the temperature by dissipating heat and allowing the computer to run on lower temperatures.

Although they are available in various shapes and sizes, the most popular and widely used case fans are 140mm case fans due to their greater airflow and quieter operation. They provide efficient cooling with lower RPM and high CFM. Due to their low RPMs, compared to the 120mm case fans, they are quieter as well which adds to the overall experience of users.

In this article, we’ve outlined some of the best 140mm case fans available and compared their features, pros, cons and specifications to give you a detailed outline of these products. Reading through this article will help you make an informed choice and enable you to get the perfect case fan for your needs.

The Coolar Master MasterFan Pro 140 is a fantastic choice for users who want an affordable fan that will cool their case as well as add some flair to its aesthetics. The MasterFan pro 140 delivers exactly what these users want. It is affordable and provides those on a budget an option to get an RGB fan.

Although the RGB lighting isn’t as impressive as the dual loop lighting on the Corsair LL140, it is still quite pleasing. The build quality is top-notch and the fan is quite reliable. However, it doesn’t exactly have top-notch performance.

The MasterFan Pro 140 produces an airflow of 46.2 CFM which is a tad bit under powered. It does have adjustable rotation speeds which can range from 650 RPM to 1550 RPM. However, the fan doesn’t dissipate intense heat as well as other premium fans do, so it should be taken into consideration if you plan on running hardware intensive tasks on your PC.

Its price is highly competitive but its performance is slightly under-par. One positive side-effect of this low-performance is that the fan operates even quieter than its competitors, which makes it a a great buy. All in all, the MasterFan Pro 140 is a great budget option for those who want their case to have a cool-looking cooling fan.
