Noctua NF-A4x10 PWM vs Thermalright Assassin X120 SE ARGB CPU Air Cooler

Overview of the Noctua NF-A4x10 PWM and Thermalright Assassin X120 SE ARGB CPU Air Cooler

The Noctua NF-A4x10 PWM is a premium quiet fan priced at £18.98, while the Thermalright Assassin X120 SE ARGB CPU Air Cooler is offered at a slightly lower price of £16.29. Both products are designed for cooling purposes but cater to different needs within the computing spectrum.

The Noctua fan, with dimensions of 40x40x10 mm, is ideal for compact spaces and applications like 1U servers or network equipment. In contrast, the Thermalright cooler is a larger, more traditional CPU cooler, measuring 120x71x148 mm, suited for desktop systems. This distinction sets the stage for how each product performs in various scenarios.

Cooling Performance

In terms of cooling performance, the Noctua NF-A4x10 PWM can achieve a maximum speed of 5000 RPM, delivering exceptional airflow in tight spaces. Its maximum noise level is rated at 19.6 dB(A), making it a very quiet option for environments where noise is a concern.

On the other hand, the Thermalright Assassin X120 SE ARGB features a fan speed of 1550 RPM and a noise level that peaks at 25.6 dB(A). While it offers a maximum airflow of 66.17 CFM, which is significantly higher than the Noctua, it also operates at a higher noise level. Therefore, users looking for maximum airflow might prefer the Thermalright, while those prioritising quiet operation may lean towards Noctua.

Design and Aesthetics

The design of the Noctua NF-A4x10 PWM is functional and understated, focusing on performance rather than aesthetics. Its award-winning A-series design incorporates Flow Acceleration Channels and an Advanced Acoustic Optimisation frame, which enhances its cooling capabilities without compromising noise levels.

Conversely, the Thermalright Assassin X120 SE ARGB brings a more vibrant aesthetic with its RGB lighting effects, appealing to gamers and users looking to match their cooling solutions with their build's colour scheme. While the Noctua prioritises efficiency and silence, the Thermalright balances performance with visual appeal, making it attractive for those who value aesthetics in their PC builds.

Installation and Compatibility

The installation process for both products is designed to be user-friendly, but they cater to different configurations. The Noctua NF-A4x10 PWM includes anti-vibration mounts and an OmniJoin adaptor set for compatibility with proprietary fan headers, making it versatile for various setups, particularly in compact or unique environments.

In contrast, the Thermalright Assassin X120 SE ARGB is designed for more traditional CPU sockets, supporting both Intel and AMD platforms, including the latest LGA1700 and AM5 sockets. This broad compatibility and the included metal fasteners ensure that it can be easily mounted in standard desktop cases, giving it an edge for general users upgrading their CPU cooling solutions.

Durability and Lifespan

Durability is a critical aspect of both cooling solutions. The Noctua NF-A4x10 PWM boasts a Mean Time To Failure (MTTF) of over 150,000 hours, an impressive figure that underscores its longevity and reliability as a cooling option.

The Thermalright Assassin X120 SE ARGB, while not explicitly stating an MTTF, uses industrial-strength materials and S-FDB bearings to ensure a long service life, reportedly up to 20,000 hours. While both products are built to last, the Noctua clearly stands out in terms of expected lifespan, making it a potentially better investment for long-term use.

Noise Levels

Noise levels are a significant consideration for many users, particularly in quiet environments. The Noctua NF-A4x10 PWM operates at a maximum of 19.6 dB(A), which is exceptionally low and ideal for users who prioritise silence, such as in home theatres or office spaces.

In comparison, the Thermalright Assassin X120 SE ARGB has a higher noise level of 25.6 dB(A). While this is still relatively quiet, it does not match the Noctua's performance in this regard. Therefore, if noise reduction is a top priority, the Noctua is the superior choice.

Price Comparison

When looking at the price, the Noctua NF-A4x10 PWM is priced at £18.98, whereas the Thermalright Assassin X120 SE ARGB is slightly less expensive at £16.29. The price difference of £2.69 may seem minor, but it reflects the different target markets and applications for each product.

For users needing an ultra-quiet solution for small spaces, the investment in the Noctua may be justified. However, for those looking for a more robust cooling solution for a standard desktop build, the Thermalright offers excellent value for money with its superior airflow capabilities and aesthetics.

Which should you buy?

Choosing between the Noctua NF-A4x10 PWM and the Thermalright Assassin X120 SE ARGB depends largely on your specific cooling needs and preferences. If you require a compact, ultra-quiet fan suitable for tight spaces and prolonged use, the Noctua is the ideal choice, thanks to its high RPM, low noise level, and impressive durability.

However, if you are looking for a powerful CPU cooler with good airflow, stylish RGB aesthetics, and compatibility with a variety of Intel and AMD sockets, the Thermalright Assassin X120 SE ARGB stands out as a strong contender. Ultimately, consider your setup and what aspects—performance, noise, aesthetics, or price—are most important to you before making a decision.
