140mm Case Fans Product Reviews
1 Corsair LL Series LL140 – Best Premium 140mm Case Fan
Case fans have evolved a lot and aren’t merely rigid plastic frames surrounding the fans anymore. They aren’t only a cooling device anymore but a “complete package.” Today, many fans have added RGB LED lighting and other features that take your PC case or CPU cooler to another level.
The Corsair LL140 case fan is part of the Dual Light Loop series, and the purpose isn’t only to provide the user with impressive and silent performance but also to provide you with some of the best RGB LED controls built into it.
Dual light loop with 16 LEDs
The Dual Light Loop Fans are designed with sixteen LEDs, with most of them around the edges. A few are placed in the hub, and with connections made to proprietary devices, the visuals that this case fan provides is awe-inspiring. When buying the LL140, you will have to start with the dual 140mm kit since they include the Lighting Node Pro and the RGB Lighting Hub, which aren’t included in the single fan kit.
If you want more than two fans, you can also choose a single kit and maximize your machine’s cooling and aesthetics since every node holds up to six fans. It’s easy to control the lighting since all LEDs are handled through the Corsair LINK software, where all the magic happens. By using the software and controller, you can switch between a vast number of flashing light modes, including “Colour Cycle,” “Rainbow Wave,” “Visor,”…etc.
The front of the LL140 fans has a black frame with a white LED ring around the blades. The structure also has rubber pads to eliminate vibrations against the chassis or cooler. The fans have a twenty-three inch 4-pin PWM controllable fan power lead, and another twenty-three inch RGB LED control cable that you plug into the Lightning Node Pro module.
The Corsair LL140 is powerful as well, the fans reach a maximum RPM of 1300, and you can control the speed with the PWM. It also has a decent airflow rating of 51.5 CFM, making it possible to game as long as you don’t over-exert your processor.
- Size: 140 x 140 x 25mm
- RGB: Yes
- Noise Level: 25 dB
- Fan Speed: 600-1300 RPM

2 Noctua NF-A14 – Best Value 140mm Case Fan for the Money
Noctua has been manufacturing fans since 2006, and we have become familiar with the NF-P12 and NF-P14 that stock the famous NH-D14 heatsink. Now they have opened us to a whole new series of fans, the A-series that ranges from 40-140mm. But the fan we’re focusing on is the Noctua NF-A14.
The Noctua NF-A14 is equipped with “Noctua’s AAO (Advanced Acoustic Optimization) standard.” They also include practical aerodynamic design measures like the Flow Acceleration Channel that reduce flow separation.
Control the speed…
The NF-A14 features the SSO2 bearing, which was first seen on the Noctua NF-F12. It’s a hydrodynamic bearing with a magnet. The magnetic field stabilizes the rotation, leading to greater airflow efficiency and longer life. The fans are driven by Noctua’s silent integrated PWN allowing you to tweak the speed between 300 to 1500 RPM. Fixed silicon pads in all corners absorb vibrations that are produced when the blades rotate at higher speeds.
As a result, the fans won’t rattle inside the case. At 1500 RPM, the NF-A14 pushes out an outstanding 82.5 CFM while keeping the noise level below 24 dB. The Noctua NF-A14 has a standard 140mm frame. So, when mounted, the corners are closed, preventing any backflow through open corners.
- Size: 140 x 140 x 25mm
- RGB: No
- Noise Level: 24 DB
- Fan Speed: 1500 RPM
- Bearing: SSO2
- Airflow: 82.5 CFM
The Noctua NF-A14 is, without doubt, one of the best static pressure fans in the 140mm category. Static pressure fans are commonly used on larger components like GPUs and radiators. Don’t be discouraged by the unattractive beige color, as this truly is a beast.
The fans combine excellent performance with a six-year warranty to safeguard your investment. So what are you waiting for? Buy the Noctua NF-A14 now!
- Has a broad 300-1500 RPM speed.
- Includes a 6-year manufacturer warranty.
- 150,000 hours of operational life span.
- 4-pin PWM version for tweaking fan speeds.
- The square frame design makes it perfect for water cooling.
- Anti-vibration silicone pads.
- Quite expensive.
- The beige color may be off-putting.
3 Corsair ML140 PRO RGB – Best Rated 140mm Case Fan
Fans with magnetic levitation blades are nothing new to the Corsair line-up. They have been selling them for quite some time now. They started with single and twin pack fans, with a simple grey frame and blades, but they have evolved.
The ML140 PRO was first sold in solid LED color with red, white, and blue as an option to add a little bit of flair to the PC case. But since then, they have started adding RGB lighting to the ML140 PRO.
Single or dual-pack configuration?
Like the Dual-Light Loop fans, the ML-series fans are available in a single or dual pack configuration. But the single fans LED effects won’t work on their own since they are sold as additions to the dual pack kits. Like the LL140, the single pack doesn’t include the RGB lighting hub or the Lighting Node Pro.
The dual pack includes a few extra things, but apart from that, the ML140 fans deliver an airflow of 55.4 CFM with 1.27mm H20 of static pressure. The fan speed is controllable via the PWM. The fan speed varies between 400 RPM to 1,200 RPM, and the sound level is excellent, with a rating of 20.4 dB. They also include a five-year warranty.
At first glance…
At first glance, the ML140 PRO looks like any other case fans with black frames and grey rubber anti-vibration pads in each corner. The difference is that the seven fan-blades are white, and each hub on the fan has four RGB LEDs inside, providing you with a pretty cool light show.
The ML140 PRO has a four-pin power connection for the fan and a much thinner four-pin connection for the included fan hub.
- Size: 140 x 140 x 25mm
- RGB: Yes
- Noise Level: 20.7 dB
- Fan Speed: 400 – 1200 RPM
- Bearing: Magnetic Levitation
- Airflow: 55.4 CFM
But are they the Best 140mm Case Fans you can buy?
The ML140 PRO are great performers, very well built, and backed by good packaging, customer support, and warranty. The RGBs look good, and there are a lot of reasons to justify the price. But it would be best if you opted for the dual-pack, so you don’t miss out on the RGB effects and the rubber corners.
The ML140 PRO gives you a good bang for your buck and will suit almost any build.

6 ARCTIC BioniX P140 – Best Budget 140mm Case Fan
The ARCTIC BioniX P140 case fans are optimized for static pressure and include a few technical improvements like a 0dB mode. The BioniX P140 is available in four different colors, red, white, grey, and grey/white, making it suitable for all PC builds.
The airflow and high static pressure are the main features and make the fans suitable for use with pinholes and filters for increased air resistance. The fans’ efficiency has also improved compared to previous models.
The PWM sharing technology and 0dB mode…
The BioniX P140 only requires a 0.15A input current. It also promotes the PWM sharing technology, but it merely hides the fact that the PWM connections are “looped through,” making it possible to connect several fans to one of the PWN connectors on the motherboard.
This will increase the PWM load, and since some motherboards only provide 1.0A current for these connections, a series of five fans are recommended. The speed is adjustable from 200 – 1950 RPM.
The new 0dB mode feature enables the fan to switch off as soon as the PWM signal goes below 5%. The motor is a low vibrating one, so there are no installed anti-vibration rubbers.
- Size: 140 x 140 x 28mm

Best 140mm Case Fans Buying Guide
Computer components, including RAM, processors, and graphics cards, have increased in both speed and power consumption. This has resulted in an increased amount of heat produced by the system as well. When the heat rises, the motherboard tends to throttle or scale down its performance to bring temperatures down to normal levels.
This means that the CPU and other components don’t run at their full potential. Case fans help remove the excessive heat from the case to enhance the performance.
What’s Essential When Buying A Case Fan?
There are a few key factors to look for when buying a case fan. So we have listed them here to help you…
Case fans vary in sizes ranging from 25 to 140mm, but the most popular ones are 80, 120, 140, and 200mm. Lately, the 140mm case fans have become increasingly popular since the larger blades are more efficient and circulate more air at lower speeds. They are also quieter.
- Power Connection Type
How does the fan connect to the system? The 4-pin is the most common and connects directly to the 4-pin connector on the motherboard. A 3-pin will also connect to a 4-pin connector but does so using only three pins.
The Molex connection type connects directly to the power supply instead of the motherboard, and some fans feature a combination of the two, for example, a Molex and 3-pin.
- Fan Speed
The fan speed is measured in revolutions per minute (RPM); the speed influences the performance and is determined by the fan size. Larger case fans run at lower RPM, circulate more air, and are, in general, quieter.
- Noise Levels
Noise levels are computed in dBA (decibels) and tell you how loud the fan gets when running at maximum RPM. The levels usually range from 10 dBA to 35dBA, with noise levels increasing as the case fans size decreases.
- Air Flow
Another critical factor is the airflow measured in cubic feet per minute (CFM) and describes the amount of air the fan can push per minute. It’s best to opt for a fan with a high CFM while still considering the size and speed.
- Bearing Type
The three most common bearing types are sleeve, ball, and hydrodynamic (fluid) bearings. The hydrodynamic is self-lubricating and the most durable of the three. The ball bearing is a little louder than the sleeve bearing but will last longer.
