Best 140mm Case Fans in 2021

For better cooling, a computer case needs case fans attached inside the computer case for active cooling. The main function of a case fan is to create an airflow inside the computer case by pulling fresh cool air into the computer case and pushing the warm air out of the computer case.

At a Glance:

Some case fans are designed to cool specific computer components inside the computer case, such as the GPU, motherboard, or CPU. These fans help lower the temperatures of these components that resulting in better performance and longer lifespan of these components. There are various sizes available in the market for the case fans depending on your needs, and the most common sizes are 120mm and 140mm. In this article, we will go through some of the best 140mm case fans, so let’s start.

Since 2006, Noctua has been manufacturing fans, and we are now quite familiar with the NF-P12 and the NF-P14 that stock the famous NH-D14 heatsink. However, Noctua has opened us to a whole new series of fans, the A-series, from 40mm to 140mm. The fan we are going to be talking about is the Noctua NF-A14 case fan. The Noctua NF-A14 is the best value 140mm case fan equipped with what Noctua calls “Noctua’s AAO (Advanced Acoustic Optimisation) standard.” Noctua has also equipped the Noctua NF-A14 case fans with sophisticated aerodynamic design measures such as the Flow Acceleration Channel.

The Noctua NF-A14 case fans feature the SSO2 bearing that first appeared with their Noctua NF-F12, and Noctua’s PWM fans are all driven by Noctua’s silent PWM integrated circuit chips. This means there’s no clicking whatsoever; even when the voltage is changed, the user will not hear any clicking. The Noctua NF-A14 case fans and all the new-generation Noctua fans have Anti-Vibration Pads the soft brown corners. The fan also has airflow enhancements as stepped inlets and inner surface microstructures and also uses the corners as flare vents for fan output which makes it the best 140mm case fan. The Noctua NF-A14 case fans feature metal-bearing shells.

Noctua NF-A14 has a standard 140mm frame which means that when it is mounted, the corners will not be open, and there will be no backflow through the open corners. It also has the “Flow Acceleration Channel” present on the blades. By looking at the seven wide-chord blades, you can tell that this fan will emphasize static pressure in addition to airflow.

Pros

  • No less than 150,000 hours of MTBF
  • Long life and you also get a 6-year warranty
  • Provides stunning performance
  • Excellent build quality

Cons

  • A little bit expensive

Case fans have come a long way and are not simply hard plastic frames that surround the fan to the point that now fans are a “complete package” and aren’t simply a cooling device anymore. Fans nowadays add RGB LED lighting, and some manufacturers add various modes of LED control to take any PC case or CPU cooler to the next level. Today we have Corsair LL140 case fans that we will be talking about here, Corsair’s Dual Light Loop Series of fans. The purpose of such fans is to provide the users with impressive performance and silent performance simultaneously and take it a step further, providing the enthusiasts with some of the best RGB LED control built into it. Corsair designs dual Light Loop Fans with a total of sixteen LEDs; many of these are around the edge, a few are in the hub, and with the connections made to proprietary devices, the visuals that the Corsair LL140 case fans will provide the enthusiasts is awe-inspiring and is one of the best.

When picking up these fans, you will have to start with a dual 140mm kit as these packs are shipped with the Lighting Node Pro and the RGB Lightning Hub, which is not available in the single fan packaging. Keep in mind that you are not stuck with two fans; you can pick a single kit and maximize the cooling and aesthetics with up to a total of six fans per node. All of the LED control is handled via the Corsair LINK software. The Corsair LL140 fans come in a typical Corsair products package with a black background and bright yellow accents. A pair of Corsair LL140 fans can be seen on the front of the box. The front of the fans has a black frame, a white LED ring around the blades, and opaque blades and hub. The Corsair LL140 has rubber pads on the frame to eliminate vibration against the chassis or cooler.

There is a 4-pin PWM controllable fan power lead with a length of twenty-three inches, and the other cable is the RGB LED control which plugs into the Corsair Lighting Node Pro module and has a length of twenty-three inches as well making it the best RGB 140mm case fan. LINK software is the place where all the magic happens with the Corsair LL140 fans. However, you do have to plug in a few extra cables and cable manage those cables, but the RGB lighting and the performance the Corsair LL140 fans provide are awe-inspiring.

Pros

  • Sixteen RGB LEDs
  • Silent
  • Lightning Pro Node Controller

Cons

  • Expensive
  • Performance not impressive

For some time now, Corsair has been selling fans that have levitation blades magnetically. Corsair started with a single and a twin pack fans with just gray blades and black frames, but now these have evolved. These ML fans by Corsair were offered in solid LED color with options of red, white, and blue to add a little bit of bling to the PC case, but Corsair did not stop there. As RGB is so hyped nowadays, it only makes sense that Corsair adds RGB to their Corsair ML140 case fans. Corsair ML140 case fans are the best corsair 140mm case fans. Like the Dual-Light Loop fans, Corsair offers their ML-Series fans in a single pack or a dual pack configuration, but keep in mind that the singles LED effects will not work on their own because they are sold to be additions to the dual pack kits. As mentioned earlier, the single-pack fans do not come with the RGB lighting hub; they do not come with the Lighting Node Pro either, and it kind of makes sense.

Dual pack fan boxes come with a few extra stuff, but apart from all that, the Corsair ML140 fan is designed to deliver 55.4 CFM of airflow with 1.27mm H20 of static pressure which makes it the best premium 140mm case fan. They are PWM controlled, and the sound levels are rated at only 20.4 dB(A), and the fans also come with a five-year warranty. The Corsair products, the Corsair ML140 case fans, come in a black box with yellow accents. A pair of Corsair ML140 case fans can be seen on the front of the box.

The inner packaging is quite robust, and stacking the fans with the hardware box in between them helps in keeping the heaviest bits apart from each other so that they don’t get damaged. On the first look, the Corsair ML140 case fans may look like the rest with black frames and gray rubber anti-vibration pads in the corners. The different thing here is that the seven blades of the fans are white, and each hub on the fans has four RGB LEDs inside of it that provide the user with quite a light show. There is a 4-pin fan power connection and a much thinner 4-pin connection that goes to the fan hub that the fans come with. The Corsair fans offer the best options for LED control and user-friendly UI, which will be helpful for the enthusiasts out there.

Pros

  • Works well in PC Case
  • Four RGB LEDs
  • Speed Control

Cons

  • Requires 12V PWM
  • Quite an Expensive
  • Noisy at high speeds

Phanteks were known for their excellent CPU air coolers until recently. However, with the launch of Phanteks Enthoo Primo PC case, they made a statement of taking on custom water cooling in stride, and Phanteks also backed it up with cases to follow. Phanteks launched their case fans, specifically the Phanteks PH-F120MP and the Phanteks PH-F140MP, but here we will be talking about the Phanteks PH-F140MP 140mm case fans. The Phanteks PH-F140MP case fan is a high static pressure fan that was actually marketed for radiators and it’s quite cheap compared to others which makes it the best budget 140mm case fan.

The package that these fans come in is a nice box that tells you right away what the product is while also showing you a part of the fan cleanly. When we open the box, the fan is revealed along with a set of 4 self-tapping screws, no rubber mounts, no vibration dampeners. The Phanteks PH-F140MP fans are actually meant to be used on radiators with screws provided with the radiator unit, which is why the fan comes packaged like this. However, the Phanteks PH-F140MP fan does perform really well as a case fan, and you can use these included four screws to mount the Phanteks PH-F140MP fans to the case.

The Phanteks PH-F140MP fans have rubber pads attached to the corners to provide some vibration dampening. It has a magnetic, brushless DC motor that draws a maximum of 0.2A of maximum operating current. According to the nature of the PWM devices in the PC DIY sector, the fans should be left running at a constant of 12V, so the maximum operating power draw is 2.4W for the Phanteks PH-F140MP fan. The Phanteks PH-F140MP fan’s cables sleeving is not the best, but it is all black wires used everywhere. These cables have a length of 20 inches to use on a radiator and then a PWM splitter. It has a nice black frame and white blade design that will go with many build color schemes. It is also designed for custom watercoolers who usually need and buy multiple fans to fit on the radiators, which means that being quiet on their own will help. Cheap price and Great quality make it the best 140mm case fan.

  • Great build quality
  • Quite a Cheap
  • Quiet while Operating
  • Long-sleeved cables

Cons

Noise Level:0.08 Sones
Wattage:2.28 W
Dimension:5.51 x 1.06 x 5.51 inches

The F14 fan series was announced by the Arctic, which consists of six new 140mm fans with a wide variety of features. However, these fans are all part of the same series; they have little in common. The F14 series of fans have only two traits: the six-year warranty and the physical size of 140mm. The dimensions of all of the six fans are 140mm x 140mm x 27mm (W x L x H). The ARCTIC F14 PWM PST CO is the best mid-range 140mm case fan that uses dual ball bearings, while most fans use fluid dynamic bearings. The F14 Silent fan and the F14 TC fan are the two most unique fans in the list; the F14 Silent has an 800 RPM, which is lower than the other fans in the F14 fan series, which ranges from 960 RPM to 1350 RPM, however lower RPM means lower noise, and it operated quieter at 0.08 Sone of the noise level.

The F14 TC is unique because it uses a temperature sensor that helps adjust the speed; while this fan spins at 960 RPM to 1350 RPM, it can also adjust its speed to keep the case between 32-38 °C. When the temperature drops below 32 °C, that is when the fan shuts off completely. The other fans in the list are also designed to shut off when the PWM signal drops below 40%. Doing this helps keep your PC relatively quiet when it is idle and helps keep it cool when at full load.

The frame of the ARCTIC F14 fan is black, while the fan itself is white. It does not have any noise dampening rubber on the corners of the ARCTIC F14 fan. But, it still operates quite silently even at full load. The ARCTIC F14 fan is a great choice for your PC build. It has an innovative blade design; the fan’s airflow is great at high speeds, while it is quite good at low speeds. However, the ARCTIC F14 fan will ensure that your PC remains cool while staying pretty silent.

Pros

  • Impressive Performance
  • Creative Blade Design
  • Operates Silently

Cons

  • Lacks Aesthetics

To start with, the ARCTIC BioniX P140 case fans are actually optimized for static pressure and offer a 0dB mode and a few technical improvements. The ARCTIC BioniX P140 is the best quiet 140mm case fan that is available in red and white colors. The package for the ARCTIC BioniX P140 case fans is a simple box in black color with accents of the color of the fan you’re getting. The front of the box has the fan itself pictured on it, along with some of the important technical data, and special features of the fans are also listed here. The focus of the airflow and the optimization to high static pressure is promoted. The fans are specifically suitable for use with pinholes and filters, which increase the air resistance.

Fan’s efficiency has also improved compared to the previous models. The ARCTIC BioniX P140 fan only requires a 0.15A of input current. It does actually benefit the “PWM sharing technology,” too; this simply hides the fact that the PWM connections of the fans are “looped through,” and therefore, several fans can be connected to one of the PWM connectors on the motherboard. This does mean that the load on the PWM port will add up. As some of the motherboards only provide 1.0A of current for these connections, so the Arctic themselves recommend on their support page not to connect more than 5 fans in series and also to check the specifications of the motherboard to be on the safe side.

The P series offers a 0dB mode as a new feature. When the PWM signal goes below 5%, the fan switches off completely. The Arctic also promotes the ARCTIC BioniX P140 fan’s motor as a low vibration one to leave the anti-vibration rubbers out of the ARCTIC BioniX P140 fans. Arctic does give a 10-year warranty on the ARCTIC BioniX P model fans. ARCTIC BioniX P140 fan does have impressive cooling performance. The ARCTIC BioniX P140 fans are audible at the maximum speed, but not too much. The ARCTIC BioniX P140 fan’s low vibration motor does perform quite well to keep the noise levels of the ARCTIC BioniX P140 fan quite low.

Pros

  • Appealing Color Schemes
  • Impressive performance
  • Low to decent noise levels

Frequently Asked Questions

Are 140mm fans better than 120mm?

The main difference is the sound; 140mm fans are larger and can move more air without moving as fast as 120mm fans. A 140mm fan moves slower and creates less noise, and hence larger the fan lesser the noise.

Who are the quietest case fans?

The corsair company makes some of the best CPU parts, and case fans are no exception. Corsair Air Series AF140 is considered widely as one of the best and quietest case fans.

What is the best 120mm case fan?

F12 PWM is considered one of the best 120mm case fans, and it allows the motherboard to run the Fan at the precisely optimized speed.

Are bigger case fans better?

Not in the sense of cooling because you can get the same amount of cooling with a smaller fan, but they are usually quiet, so yes, bigger fans are better and quieter than smaller ones.
