Noctua NH-U9S vs Thermalright Assassin King 120 SE ARGB CPU Air Cooler

Overview of the Noctua NH-U9S and Thermalright Assassin King 120 SE ARGB

When comparing the Noctua NH-U9S and the Thermalright Assassin King 120 SE ARGB, the most striking difference is their price. The Noctua NH-U9S is priced at C$74.95, while the Thermalright Assassin King is significantly more affordable at C$24.59. This difference in cost reflects the unique features and capabilities of each cooler, making them suited for different user needs and budgets.

The Noctua NH-U9S is designed for compact builds without sacrificing cooling performance, while the Thermalright Assassin King 120 SE ARGB offers a more budget-friendly option with appealing aesthetics but potentially less performance in high-demand scenarios.

Design and Compatibility

The design of the Noctua NH-U9S is compact and single-tower, standing at only 125mm in height. This makes it particularly ideal for HTPCs, ITX, and Small Form Factor builds. Its design ensures that it does not overhang the RAM or PCIe slots on most current motherboards, providing excellent compatibility and ease of installation.

In comparison, the Thermalright Assassin King 120 SE ARGB measures 148mm in height, which may limit compatibility in particularly tight cases. However, it is still designed to fit medium-sized computer cases, thanks to its thoughtful dimensions of 120mm in length and 73mm in width. Both coolers support a range of Intel and AMD sockets, ensuring they can cater to various systems.

Cooling Performance

Cooling performance is a critical factor for any CPU cooler, and here the Noctua NH-U9S stands out with its highly optimised NF-A9 92mm fan. This fan features PWM support and a Low-Noise Adaptor, providing automatic speed control for ultra-quiet operation. The NH-U9S is renowned for its cooling efficiency, particularly in environments where noise levels need to be minimal.

The Thermalright Assassin King 120 SE ARGB, equipped with a 120mm PWM fan operating at a maximum speed of 1550 RPM, also aims to provide effective cooling with a maximum airflow of 66.17 CFM. Its noise level is rated at a maximum of 25.6 dB(A), which is relatively quiet, although it does not explicitly match the Noctua’s emphasis on low-noise operation. Therefore, while both coolers deliver cooling performance, the Noctua may have the upper hand in quieter environments.

Aesthetic Appeal

Aesthetics play a significant role in many builds, and the Thermalright Assassin King 120 SE ARGB features colourful ARGB lighting effects that can enhance the visual appeal of a rig. This aspect is particularly attractive to gamers and PC enthusiasts who enjoy customising their setups.

On the other hand, the Noctua NH-U9S adopts a more utilitarian design with a focus on performance rather than flashy features. While it may not have RGB elements, its classic brown and beige colour scheme is well-regarded among Noctua fans for its professional appearance. Therefore, if aesthetics are a priority, the Thermalright Assassin King will likely be the more appealing choice.

Installation and Maintenance

Ease of installation is crucial for any CPU cooler, and both the Noctua NH-U9S and the Thermalright Assassin King 120 SE ARGB come with their unique mounting systems. The Noctua includes the SecuFirm2 mounting system, which is designed for straightforward installation on various Intel and AMD sockets. Users appreciate the included high-end NT-H1 thermal paste, which simplifies the installation process.

The Thermalright Assassin King also provides metal fasteners for both Intel and AMD platforms, ensuring a secure installation. However, it does not specify the inclusion of thermal paste, which may necessitate an additional purchase for some users. Overall, the Noctua may have an edge in terms of user-friendly installation and included accessories.

Warranty and Reliability

When investing in a CPU cooler, warranty and reliability are important considerations. The Noctua NH-U9S is backed by a 6-year manufacturer’s warranty. This assurance of quality and longevity speaks volumes about Noctua’s confidence in their product.

In contrast, the Thermalright Assassin King does not specify a warranty period in the provided details. While Thermalright has been around for over 20 years and is known for its reliability, the lack of an explicit warranty period might make some consumers hesitate. Therefore, the Noctua NH-U9S offers greater peace of mind in terms of long-term reliability.

Price Point

A major deciding factor between the Noctua NH-U9S and the Thermalright Assassin King 120 SE ARGB is their price. The NH-U9S is positioned at C$74.95, which reflects its premium build quality, advanced features, and strong brand reputation. In contrast, the Thermalright Assassin King is priced at a much lower C$24.59, making it an attractive option for budget-conscious consumers.

While the price difference is significant, it is essential to consider what you are getting for that additional cost. The Noctua may offer superior cooling performance, lower noise levels, and a longer warranty, making it a better long-term investment for serious users.

Which should you buy?

Deciding between the Noctua NH-U9S and the Thermalright Assassin King 120 SE ARGB ultimately comes down to your specific needs and budget. If you are looking for a high-performance cooler with a compact design, exceptional cooling efficiency, and a long warranty, the Noctua NH-U9S is the clear choice. However, if you are on a tight budget and want an aesthetically appealing cooler that still offers decent performance, the Thermalright Assassin King 120 SE ARGB is a solid option. Each cooler has its strengths, making them suitable for different types of users and builds.
