Noctua NF-A8 PWM vs Thermalright Assassin X120 SE ARGB CPU Air Cooler

Overview of the Noctua NF-A8 PWM

The Noctua NF-A8 PWM is a premium quiet fan that offers excellent performance in a compact design. Priced at £24.59, it features a maximum speed of 2200 RPM with a noise level of just 17.7 dB(A). This makes it an ideal choice for users looking for efficient cooling without the distraction of loud fans.

Designed specifically for compact PC cases, including HTPCs and Small Form Factor builds, the NF-A8 is versatile enough for various applications, such as intake and exhaust systems. Its 4-pin PWM capability allows for automatic speed control, ensuring optimal cooling based on the system's needs. Additionally, the fan boasts a reliability rating of over 150,000 hours MTTF, highlighting its durability for long-term use.

Overview of the Thermalright Assassin X120 SE ARGB CPU Air Cooler

The Thermalright Assassin X120 SE ARGB CPU Air Cooler is a more affordable option, retailing at £16.29. It features a maximum fan speed of 1550 RPM and a higher noise level of up to 25.6 dB(A), which may be a consideration for users prioritising silence.

With dimensions of 120x71x148 mm, this cooler is designed to fit medium-sized computer cases and is compatible with both Intel and AMD platforms. The cooler includes a range of ARGB lighting effects, adding a visual appeal to the build. Its design utilises 4×6mm heat pipes, enhancing heat dissipation and overall efficiency, making it suitable for gamers and high-performance users alike.

Design and Build Quality

The design of the Noctua NF-A8 PWM focuses on compactness and efficiency. Measuring 80x80x25 mm, it is structured with Flow Acceleration Channels and an Advanced Acoustic Optimisation frame, which contribute to its quiet operation and high airflow. The inclusion of anti-vibration mounts and a Low-Noise Adaptor further enhances its usability in noise-sensitive environments.

In contrast, the Thermalright Assassin X120 SE ARGB has a larger footprint at 120x71x148 mm, which caters to a different segment of the market. Its build features an aluminium heat sink and metal fasteners, ensuring sturdy installation on various CPU sockets. While the design may take up more space, it provides a striking visual element with its ARGB lighting, appealing to users who value aesthetics as much as performance.

Cooling Performance

When it comes to cooling performance, the Noctua NF-A8 PWM offers a maximum airflow efficiency of over 150 m³/h, making it a strong contender for compact applications. Its ability to scale from 450 to 2200 RPM allows for tailored cooling depending on the system load, making it suitable for both low and high-performance scenarios.

On the other hand, the Thermalright Assassin X120 SE ARGB boasts a maximum airflow of 66.17 CFM, which, while lower than the Noctua, is still commendable for a CPU cooler. The presence of 4×6mm heat pipes enhances heat dissipation, making it effective for maintaining lower CPU temperatures under load. However, for users with high-performance CPUs, the NF-A8 may provide more robust cooling capabilities.

Noise Levels

Noise levels are a critical factor for many users when choosing cooling solutions. The Noctua NF-A8 PWM excels with a maximum noise level of only 17.7 dB(A), making it one of the quietest fans available. This is particularly beneficial for users who require a silent environment, such as in office or home theatre setups.

Conversely, the Thermalright Assassin X120 SE ARGB has a higher noise level of up to 25.6 dB(A). While this is still relatively quiet compared to many stock coolers, it may not meet the expectations of users who prioritise silence above all else. If noise performance is a key consideration, the NF-A8 PWM clearly holds the upper hand.

Compatibility and Installation

The Noctua NF-A8 PWM is designed primarily for compact cases, making it ideal for users with limited space. Its 4-pin PWM compatibility allows for straightforward integration with various motherboards, facilitating easy installation. The inclusion of anti-vibration mounts and fan screws further simplifies the setup process.

In contrast, the Thermalright Assassin X120 SE ARGB supports a broader range of CPU sockets, including various Intel and AMD configurations. With its more extensive installation kit, it caters to users building mid-range to high-end systems. However, the larger size may pose challenges in compact builds, making careful case selection essential for potential buyers.

Price-to-Performance Ratio

The Noctua NF-A8 PWM is priced at £24.59, reflecting its premium quality and performance capabilities. This price may deter budget-conscious users, but for those prioritising silent operation and long-term reliability, the investment could be justified.

On the other hand, the Thermalright Assassin X120 SE ARGB, at £16.29, offers a compelling price-to-performance ratio, particularly for those looking to enhance their cooling without breaking the bank. While it may not match the NF-A8 in terms of noise and maximum RPM, its features, including ARGB lighting and solid cooling performance, make it an attractive option for gamers and casual users alike.

Which should you buy?

Choosing between the Noctua NF-A8 PWM and the Thermalright Assassin X120 SE ARGB ultimately depends on your specific needs and priorities. If silent operation and compact design are paramount, the Noctua NF-A8 PWM is the clear winner, offering superior noise performance and reliability. However, if you are looking for an affordable cooling solution with aesthetic appeal and adequate performance for medium-sized cases, the Thermalright Assassin X120 SE ARGB is a solid choice. Ultimately, assessing your budget and application will guide you to the right decision.
