Noctua NF-A4x20 PWM vs Corsair iCUE LINK LX120-R RGB 120mm PWM Reverse Fans

Design and Aesthetics

The Noctua NF-A4x20 PWM has a utilitarian design focused on performance and noise reduction, while the Corsair iCUE LINK LX120-R RGB 120mm PWM Reverse Fans boast a striking aesthetic with advanced RGB lighting. Noctua's fan is compact at 40x40x20 mm and is designed primarily for quiet operation, making it ideal for 1U servers and networking equipment. In contrast, the Corsair fan features dual light loops with 18 LEDs per fan, providing vibrant, customisable lighting that can sync with other iCUE RGB devices, appealing to gamers and PC builders looking for eye-catching setups. The Corsair’s reversed rotor design enhances the visibility of its RGB ring, setting it apart visually.

Performance and Efficiency

Performance-wise, the Noctua NF-A4x20 PWM has a maximum speed of 5000 RPM, delivering superior airflow and a maximum sound level of just 14.9 dB(A), which is remarkably quiet for high-speed fans. This makes it an excellent choice for environments where noise is a critical factor. On the other hand, the Corsair iCUE LINK LX120-R can reach speeds of up to 2400 RPM, achieving airflow of 66.7 CFM and a static pressure of 4.72 mm H2O. While it operates at a lower speed than the Noctua, its airflow capacity and static pressure make it effective for cooling radiators and ensuring optimal system performance.

Noise Levels

In terms of noise levels, the Noctua NF-A4x20 PWM excels with a maximum sound output of only 14.9 dB(A). This extremely low noise level is a significant advantage for users who require a quiet operating environment, such as in home theatres or office settings. The Corsair iCUE LINK LX120-R, while designed for quiet operation with its Magnetic Dome bearing, does not specify a noise level, indicating it may be louder than the Noctua when operating at maximum speeds. Therefore, if minimising noise is a top priority, the Noctua fan is the clear winner.

Installation and Compatibility

The Noctua NF-A4x20 PWM comes with a comprehensive installation kit that includes anti-vibration mounts, fan screws, an extension cable, a Y-cable, and an OmniJoin adaptor set for proprietary fan headers. This makes it highly versatile for various setups, especially in tight spaces. In contrast, the Corsair iCUE LINK LX120-R is designed for easy installation with its included iCUE LINK bridge connectors, allowing for a seamless connection of multiple fans to the iCUE LINK System Hub using a single cable. While both fans offer ease of installation, the Noctua's compatibility with a broader range of devices, including network equipment and DVRs, gives it an edge in versatility.

Longevity and Reliability

Longevity is a strong point for the Noctua NF-A4x20 PWM, boasting a mean time to failure (MTTF) of over 150,000 hours. This statistic highlights its reliability, making it a suitable option for continuous operation, such as in servers or storage devices. The Corsair iCUE LINK LX120-R, while also built for durability, does not provide specific longevity metrics. However, it features a Magnetic Dome bearing which is designed to reduce friction and noise, contributing to its longevity. For users prioritising long-term performance, the Noctua fan is a more reliable choice based on available data.

Price Point

The Noctua NF-A4x20 PWM is priced at £18.40, making it an affordable option for customers seeking high-quality cooling without breaking the bank. In contrast, the Corsair iCUE LINK LX120-R is significantly more expensive at £64.99. This higher price reflects its advanced features, such as RGB lighting and the ability to connect multiple fans seamlessly. However, for those who need a straightforward, effective cooling solution without additional frills, the Noctua offers excellent value for money.

Target Audience

The Noctua NF-A4x20 PWM is perfect for users who prioritise silent operation and reliability, such as server administrators and professional users who need efficient cooling for network devices. Its compact size and quiet performance make it suitable for environments where noise is disruptive. Conversely, the Corsair iCUE LINK LX120-R appeals to gamers and PC enthusiasts who value aesthetics and customisation. With its vibrant RGB lighting and modern design, it stands out in custom builds, catering to those who want both performance and style.

Which should you buy?

In conclusion, the choice between the Noctua NF-A4x20 PWM and the Corsair iCUE LINK LX120-R depends on your specific needs. If you require a fan that excels in quiet operation, longevity, and versatility for various devices, the Noctua NF-A4x20 PWM is the superior choice at £18.40. However, if aesthetics, customisable RGB lighting, and connecting multiple fans with ease are your priorities, the Corsair iCUE LINK LX120-R, priced at £64.99, will better suit your setup. Ultimately, both fans serve distinct purposes tailored to different user preferences.
