Is your PC your pride and joy? Perhaps you’re only getting started with your first build, or you’re looking to replace or improve something you already have. No matter, we believe that for the majority of us, our computer represents an investment of time, effort, and money that makes it quite precious to us.

High-end computers can have a cost that falls into the thousands of dollars, so it’s crucial that we do our best to keep them in good health. The best and most recommended way is to provide a lot of cooling.

Case fans make up a crucial part of every PC build, be it a top-notch gaming rig or a simple office computer. Without proper cooling, PCs tend to bottleneck, perform badly, or worse yet — break down. That’s why you’re doing the right thing by wanting to pick up a couple of 140mm fans!

At WePC, researching and testing computer components is our passion project and we’re here to share that with you. Sifting through a sea of choices can be quite as difficult as it is time-consuming, so let us deal with all that for you.

Below you’ll find a comprehensive guide on all things related to 140mm fans, along with our best picks for this year. Read on, because your perfectly cooled rig is just a few minutes away!

The Best 140mm Fan

Corsair ML140

Editor's Rating

★★★★★ 4.7/5

Pros

Cons

As long as you have the option, when building a top-notch gaming rig it’s always good to go with high-end fans to match. When it comes to the top of the line products, we recommend the Corsair ML140.

Much like the Arctic we recommended above, this fan has a stylish black and white design that will not overpower the inside of your case. They lack LED lights, but what they lack in simple design they make up for in performance.

One of the best things about this dual pack of fans is the fact that they come with a magnetic bearing. This means that they harness magnetic levitation technology in order to function. The benefits of that are simple and enjoyable. You can expect lower noise, a longer lifespan, and improved performance.

The RPM is adjustable and can reach up to 1600 RPM with a high 97 CFM airflow. You’ll find that you can tailor these fans to your needs, switching between high and low cooling based on what you’re up to.

Corsair has a custom rotor design that optimizes the balance between high static pressure and high airflow, which makes it a good fit for very demanding builds. Whether you’re a gamer or a content creator, you’ll find the cooling more than adequate.

While normally rather quiet, these fans may have a tendency to get louder over time if used at top speeds. They’re still not overly loud, but if you’re looking for the quietest build possible, read on below to check out our recommendation in that department.

Overall, these high-end fans are really impressive in terms of performance and longevity. If you’re looking for something made to last, you’ll probably want to check them out.

The Best Silent 140mm Fan

ARCTIC F14 Silent

Editor's Rating

★★★★★ 4.7/5

Pros

Cons

Starting with its amazing efficiency and ending with the long service life, Arctic F14 has truly earned our coveted “Best Overall” spot. Considering that it succeeds on multiple levels, we had a really easy time naming it the best of the best for our guide.

As far as design goes, Arctic has used their tried and true minimalistic approach to bring forth a classic mix of black and white without LED lights. Not all non-LED fans look good in every case, but this one will blend in just right without looking dull. We believe that the majority of builds will suit this type of aesthetic.

Looks are nice and all, but it’s the performance that we care about the most, and we’re sure you do too.

This is one of the most energy-efficient case fans we’ve ever seen. It stops when your computer is idle and it adjusts to what you’re doing, never going past 800 RPM. Combined with 46 CFM, it delivers strong, reliable cooling without making your fans work overtime.

It has a fluid dynamic bearing system, which means that its life expectancy is much greater than in static pressure models. This is a fan that, once bought, will likely stay with you until you want a replacement and should not break down even after years of use.

Arctic’s fan design is rather innovative and promotes efficient ventilation. This is due to the way the fan blades are made, allowing them to improve airflow. The impeller is designed with a focus on removing as much noise as possible without any loss of performance.

Due to the limited RPM, we wouldn’t call this our first pick for overclocking, but it can be done — just take it easy and pace yourself to find the perfect spot.

Mixing silent performance and sheer cooling power into one neat package, this Arctic fan has impressed us on many levels. We recommend that you check it out!

The Best RGB 140mm Fan

Corsair LL Series LL140 RGB

Editor's Rating

★★★★★ 4.6/5

Pros

Cons

Corsair’s LL140 fans made it onto our list for a number of reasons, but we can bet that the first thing you’ll see here will be the incredible design of these LED fans.

This is a dual pack of RGB PWM fans that comes with some of the best color combinations that can be found on the market. Ranging from vibrant hues to soft pastels, these fans can truly light up your case and make as much of a statement as you like.

The fans include 16 independent RGB LEDs in each one, split between two separate light loops. The LED lights are controlled by the included Lighting Node PRO, Corsair’s staple software, that allows you to pick and choose between all the different variations.

Moving on to actual specs, these fans aren’t just pretty, they can actually pack a good punch. The combo of adjustable RPM (600-1300) and a good airflow of 51.5 CFM delivers a good balance between efficient cooling and low noise.

Thanks to PWM, you’re able to dynamically control the fan speed to suit your needs. The fan blades themselves are innovatively engineered, allowing for low-noise operation without sacrificing performance.

If we were to find some downsides of this 140mm fan set, we’d point out the cable management as the culprit. Be careful when installing them and try to be as tidy as you can to not get confused.

Overall, we believe that these fans simply shine — figuratively and literally — and stand out from the competition. They’re definitely worthy of a closer look.

A Solid 140mm Fan

Thermaltake Ring 14 High Static Pressure Fan

Editor's Rating

★★★★★ 4.5/5

Pros

Cons

At WePC, we like to double and even triple check every product before we recommend it to you. This is simply because we believe that your hard-earned cash should be spent on the best possible products. Due to that, we like to research cost-effective options that bring in the most features for the lowest prices.

Thermaltake’s Ring 14 is one such fan that manages to find the perfect balance in terms of pricing, but it does so at no cost to the performance. Featuring a number of good cooling solutions, this fan could probably come at a higher price — and we’d still recommend it.

The design of this fan is rather inconspicuous at first glance, but it does feature a couple of LED lights that make it shine in the dark. The colors aren’t overly bright, so this will work well in a more muted setup.

The specs are where the cost-to-performance factor truly comes into play, delivering in terms of cooling, longevity, and reliability. Compared to the standard case fan, this may offer up to 40% better cooling performance on average temperatures.

The airflow measures at 51.15 CFM, and the RPM at 1400. Due to Thermaltake’s concentrated compression blade design, this fan is engineered to focus the inner circle of air outwards. This allows the outer section to pressurize and compress.

There’s a wind blocker frame included that maximizes the static pressure and thus, reduces the amount of noise this fan makes — yes, even at high speeds. We found it to be pleasantly quiet while still packing quite a punch in terms of cooling.

If you want to get the best performance for every penny that you spend, we believe that Thermaltake makes that easy to achieve.

The Best Budget 140mm Fan

Cougar CFD14HBR

Editor's Rating

★★★★★ 4.4/5

Pros

Cons

Cougar’s bright red CFD14HBR model is remarkably quiet, but that’s not the only good quality you will find in this 140mm fan.

Let’s first talk about the design. Cougar isn’t really an LED fan, but it has 4 LED lights on the outer rim that resemble spotlights. The body of the fan itself is a bright red/orange, which, to some, can almost seem to overpower the inside of a case. However, if you like vibrant colors, you’re sure to enjoy this fan.

As far as the build itself goes, this is a very solid pick in terms of performance versus noise levels. The fans can spin at up to 1200 RPM, but even at the highest level, you’ll be pleased with the low noise output of 18 dB(A). That’s barely more than a whisper.

Part of the reason why it’s so quiet comes from the way its fan blades are built. Nine dual-layer rigid blades are capable of generating a powerful airflow, air pressure, and great cooling all throughout. All of this is done while reducing wind shear noises and noisy air turbulences.

Vibrations are kept at a minimum thanks to the way the fans have been engineered. Also, as this is a hydrodynamic bearing fan, noise is even further reduced due to the lack of friction.

As you probably know by now, HDB fans have a long life expectancy. As such, this is a fan that once picked up, is likely to stay with you for as long as you like.

We don’t recommend mounting it horizontally, as that is the one thing that may cause vibrations. It is an HDB fan, so you can mount it in any way you like, but the recommended orientation is vertical.

To achieve the lowest noise levels possible, make sure you check out Cougar’s CFD14HBR.

Final Word

We hope that you enjoyed getting to know the best 140mm fans on the market. Whenever we test anything and then work on our guides, we try to make sure that we pick something for everyone. Budget, high-end, and mid-range fans were all included in our list.

As we’ve put them through some pretty extensive testing, we feel certain that we can vouch for them — the above are truly the best fans currently on the market.

just as we said at the very beginning, picking out the right case fan can almost seem like a chore. Fans lack the exciting specs that, for example, GPUs have. Case coolers may have no direct effect on your PC’s performance in games and the like the way some other parts do, but that doesn’t make them any less important.

We hope that our guide has helped you take your pick and you’ll soon be assembling the PC of your dreams! Why don’t you let us know below what you’re planning to use in your next build?
