Dylan Howe

I analyzed the best 140mm case fans to produce my top-seven PC fans for the article. I am an avid gamer who constantly looks for the best pro gaming components and software to develop an unbeatable gaming rig. Here I’ll guide you through the best 140mm case fans for your PC.

Undeniably, the name Noctua NF-P14s stands out as my favorite pick for the best option on my list. Taking into account an expected life span of more than 150,000 hours and a top CFM of 110.3 cm/m, the Noctua can produce a lot of air flow for a long time. With a 6-year warranty, Noctua stands behind the build quality of its products. The best thing about this fan is the sound. At just 19.6 at the max RPM of 1200, this fan makes just a whisper while keeping your overclocked processors chilled out.

Another great choice from the list has the name be quiet! Pure Wings Two. With a 37.3 dBA at 1600 RPM, this fan is a little louder, but also is super powerful. It can move a ton of CFM. If RGB LED lighting is a priority criteria for your aesthetic, then the Corsair LL140 fan is another household name and a good go-to option for enthusiasts. With 16 RGB LEDs distributed in two loops, you’ll get a rainbow of lights that has compatibility with the ground-breaking Corsair iCUE software.

How to Choose the Best 140mm Case Fans for Your PC

Case fans provide a way to circulate cooling air in your computer tower in order to remove heat from all of your electronic components. This circulation provides one of the best cooling solutions, while reducing the need for thermal throttling and increasing the life expectancy of most of your electronics.

Most front fans draw large amounts of cool air from the outside environment into the case, while fans at the end expel heated air from within the computer case back out to the surrounding environment.

In addition, many fans may all be distributed within a case for circulating much more cool air to all core electronic components and heatsinks.

Here are some of my priority recommendations for identifying fans with the best build quality across several categories.

RPM

Revolutions per minute account for the speed at which the fan rotates. A higher RPMs means that the fan blades are pushing air faster, while a lower RPMs indicates that air is moving much more slowly. In most pulse-width modulated (PWM) fans, the RPM is controlled by the input current. Most of the best 140mm case fans are designed to operate at a range of RPM, such as 500 - 2,000 RPM.

Usually, using fans at a lower blade speed is a way to draw less current and make less noise. Using fans in a series or in parallel may allow you to use each fan with a voltage reducer to conserve more amperage in some budget builds. Most designs allow you to increase the blade speed to account for a higher load on the GPU or when overclocking your 10th-generation Intel CPU. This can help to maintain the best operating temperature and avoid thermal throttling in some budget builds.

It’s a good idea to account for both the maximum and the minimum RPM of case fans and make sure to look to see that they will adequately meet all of your needs.

Air Pressure

Air pressure is a way to measure the force generated by air flow accelerated by fans. Fans draw much air from the surrounding environment. Airflow is accelerated by passing through rotating blades. All of the accelerated air is then pushed into the computer tower. The more force generated by the air, the further this air will travel before decelerating, sometimes even producing a similar amount of force as produced in magnetic levitation.

In addition, if the output is incident on a surface, such as a heatsink or a radiator, then airflow with a higher air pressure can push more heat from the surface and thermal paste back into the surroundings, thereby increasing the effectiveness of radiative and convective cooling solutions. If you plan to use a 140mm case fan with a heatsink or a radiator, make sure to look for the options with the best static pressure rating possible.

CFM

Cubic feet per minute (CFM) is a measure of the amount of air flow that a 140mm case fan can accelerate per minute. CFM is the best criteria for measuring overall efficiency and performance. Even if a fan has a high RPM, the CFM may still be quite low, whereas some budget fans with lower blade speeds can still have a high CFM.

CFM is controlled by a combination of factors, such as the shape, orientation, and position of the intake part and exhaust part of the case fans. In your computer case, you want to keep as much airflow circulating as possible, while taking into account noise and amperage. Choosing high CFM fans is the best way to achieve these performance goals. High CFM fans work well in parallel and provide a variety of set-up options and usage alternatives.

RGB Lighting

The fact is that the best 140mm case fans aren’t purely functional. They enhance your aesthetics by providing a way to illuminate a budget computer case with LEDs, while making Pro gaming a much more dramatic show. The combination of visuals and each color transition are fun to look at, providing the best visual experience.

There are some special function controllers, such as the Corsair iCUE software, that provides the best way to achieve all-in-one integration to control everything like your case fans, RGB lighting, and other peripherals such as your mouse, a Cooler Master keyboard, and thumb drives from a Cooler Master hub.

Some things to consider are that RGB systems may be powered using a separate input connector (e.g., a Molex-type adapters). Most RGB systems can be coordinated with RPM to provide an at a glance look at cooling fan utilization and performance, or the RGB lighting can be a more decorative design that produces the best color scheme options for your computer cases.

Noise Profile

One of my most important recommendations to take into account in choosing your 140mm case fans is sound production and noise. While 140mm case fans may deliver peak performance for hours at a time, hearing some combination of grinding noises while you game can be a problem for people, becoming way more distracting than you may realize at first.

However, one thing to consider is that the quietest 140mm fans are not always the best fans for sound performance or noise profile. In terms of sound quality, a louder rotor with a tolerable noise profile that you don’t mind may be less distracting than another one with a softer, but high-pitch whine.

Typically, high-end fans are designed to emit multi-frequency noise over a broad frequency spectrum to produce gentler, more pleasant auditory aesthetics. Budget blades without this engineering hack are another matter, producing mono-frequency noise which can be grating for consumers.

In terms of design categories, don’t just check the volume production range of the CPU cooler, but also make sure that the blades of the 140mm case fans are all engineered to produce a pleasant sound. These are important recommendations to get the best auditory experience and performance.

Conclusion

Case fans are an essential component to look at in your gaming rig. They keep your electronics cool and functioning at an optimal temperature for best performance and 140mm case fans can be used throughout much of your budget build to improve airflow, expelling hot air from computer cases.

In conclusion, the Noctua fan is my favorite pick for the best 140mm option. With its quiet operation and high CFM, you’ll have plenty of cooling air for any task without being disturbed by things like the sound of the Noctua fans operating. The Noctua has a long life-expectancy which makes a huge difference in terms of value for money. With this cooler product, you know that you have the best quality assurance for your money.
