Thermalright Peerless Assassin 140 Black CPU Cooler vs Noctua NH-U9S

Overview of the Thermalright Peerless Assassin 140 Black and Noctua NH-U9S

The Thermalright Peerless Assassin 140 Black is priced at C$54.90, while the Noctua NH-U9S comes at a higher price of C$74.95. Both coolers are designed for effective CPU cooling but cater to different user needs and preferences.

The Thermalright Peerless Assassin 140 Black features a twin-tower design with dual fans, offering superior heat dissipation capabilities. On the other hand, the Noctua NH-U9S utilises a compact single-tower design, making it ideal for smaller builds without sacrificing cooling performance. This fundamental difference in design reflects their intended applications and user bases.

Cooling Performance

Cooling performance is critical in CPU coolers, and both the Thermalright Peerless Assassin 140 Black and Noctua NH-U9S excel in this regard but through different mechanisms. The Thermalright model features a twin-tower body with symmetrical fins and dual fans that operate at a speed of 1500 RPM, delivering an impressive air volume of 66.17 CFM. This design ensures efficient heat dissipation for high-performance CPUs.

In contrast, the Noctua NH-U9S, despite its smaller size, is equipped with a highly optimised NF-A9 92mm fan. This fan is designed for low noise operation and has PWM support, allowing for automatic speed adjustments based on temperature. This means that while the NH-U9S may not push as much air as the Thermalright cooler, it maintains a strong cooling performance in compact spaces, making it a reliable choice for smaller systems.

Size and Compatibility

Size and compatibility are crucial factors when choosing a CPU cooler, and here the two products diverge significantly. The Thermalright Peerless Assassin 140 Black measures 140mm x 157mm x 158mm, making it suitable for larger and medium-sized chassis. Its 158mm height allows for compatibility with high-profile memory and graphics cards, making it versatile for various builds.

In contrast, the Noctua NH-U9S stands at a compact height of only 125mm, which is ideal for HTPCs, ITX, and small form-factor builds. This smaller stature means that it does not overhang RAM or PCIe slots on most motherboards, making it an excellent choice for builds where space is at a premium. Users looking to build compact systems should consider this aspect seriously when making a decision.

Installation Process

The installation process can vary significantly between different CPU coolers, and this is an important consideration for DIY builders. The Thermalright Peerless Assassin 140 Black comes with all-metal fasteners and a SS2 buckle system, which simplifies the installation on a wide range of CPU models. Additionally, it includes a Y-type adapter cable to connect both fans easily, addressing potential motherboard interface limitations.

Conversely, the Noctua NH-U9S is equipped with the SecuFirm2 mounting system, which is known for its ease of installation. It also includes high-end NT-H1 thermal paste, providing everything needed for a seamless setup. This cooler’s installation process is straightforward, especially for those using Intel LGA or AMD AM4/AM5 sockets. The ease of installation of both models can appeal to different user preferences, whether they prefer a more extensive setup or a quicker, simpler installation.

Noise Levels

Noise levels are a significant consideration for many users, particularly those who prioritise a quiet computing experience. The Thermalright Peerless Assassin 140 Black operates at a noise level of 25.6 dB(A), which is relatively quiet for a cooler that offers such high airflow. This makes it suitable for gamers and professionals who require efficient cooling without excessive noise.

The Noctua NH-U9S, known for its emphasis on quiet operation, features an NF-A9 fan that has a low-noise adaptor for automatic speed control. While the exact noise level isn’t specified, Noctua is renowned for producing some of the quietest fans on the market. Users can expect an ultra-quiet operation, making it an excellent choice for those who prioritise a silent working environment.

Aesthetic Appeal

Aesthetic appeal can be an essential aspect of a build, especially for users who showcase their setups. The Thermalright Peerless Assassin 140 Black sports a sleek black design that can complement modern builds well, featuring a twin-tower structure that adds a robust look to the system.

On the other hand, the Noctua NH-U9S has a more traditional design with its brown and beige colour scheme, which may not appeal to every user. However, its compact size and elegant single-tower design can still attract those who appreciate functionality over aesthetics. Ultimately, the choice here comes down to personal preference regarding visual style.

Price Comparison

When it comes to pricing, the Thermalright Peerless Assassin 140 Black is more budget-friendly at C$54.90, making it an attractive option for users looking for high performance without breaking the bank. In contrast, the Noctua NH-U9S is priced at C$74.95, which reflects its premium build quality and brand reputation.

While the Thermalright offers great value, the Noctua cooler justifies its higher price with features like its renowned low-noise operation and easy installation. Users must weigh the benefits against their budget constraints to determine which cooler provides the best value for their specific needs.

Which should you buy?

Choosing between the Thermalright Peerless Assassin 140 Black and the Noctua NH-U9S ultimately depends on your specific requirements and build conditions. If you're looking for a high-performance cooler with superior airflow and heat dissipation capabilities in a larger chassis, the Thermalright Peerless Assassin 140 Black is an excellent choice. However, if you need a compact, quiet solution for a small form-factor build, the Noctua NH-U9S stands out as the superior option. Consider your system's dimensions, your cooling needs, and your budget before making a final decision.
