Thermalright Peerless Assassin 120 Digital ARGB Black CPU Cooler Air with 6X6mm vs Noctua NH-U9S

Overview

In the world of CPU coolers, the Thermalright Peerless Assassin 120 Digital ARGB Black and the Noctua NH-U9S are two distinct contenders that cater to different needs. The Thermalright cooler is priced at C$62.90, while the Noctua model comes in at C$74.95. This price difference reflects the unique features and specifications of each product, making them suitable for various builds and preferences.

Design and Aesthetics

The Thermalright Peerless Assassin 120 features a dual-tower design with a black finish and a digital display on the magnetic top cover, enhancing both aesthetics and functionality. Its overall height of 162mm allows it to fit in most mainstream ATX chassis. This cooler's design is not just about looks; it includes dual fans that promote efficient airflow.

In contrast, the Noctua NH-U9S has a compact single-tower design, reaching only 125mm in height. This makes it an ideal choice for HTPCs and small form factor builds, as it does not overhang RAM or PCIe slots on most modern motherboards. While the Noctua may not have the flashy features of the Thermalright, it is renowned for a classic, utilitarian aesthetic that appeals to many users.

Cooling Performance

The Thermalright Peerless Assassin 120 is equipped with dual fans that operate at a speed of 1850 RPM and can achieve an air volume of 88.89 CFM. This setup ensures effective heat dissipation, capable of handling high-performance CPUs with ease. The cooler's six pure copper heat pipes and base are designed for optimal contact with the CPU, promising efficient thermal management.

Conversely, the Noctua NH-U9S utilises a highly optimised NF-A9 92mm fan, which also offers PWM support and a Low-Noise Adaptor for quieter operation. While the NH-U9S is not as powerful in terms of airflow compared to the Thermalright, its compact design allows for decent cooling performance in constrained spaces. The Noctua is especially suited for users who prioritise silent operation without sacrificing too much cooling efficiency.

Noise Levels

When it comes to noise levels, the Thermalright Peerless Assassin 120 operates at a maximum noise level of ≤25.6 dB(A), which is relatively quiet for a dual-fan setup. This makes it a viable option for gamers and content creators who prefer a quieter working environment without compromising on cooling performance.

On the other hand, the Noctua NH-U9S is designed with silent operation in mind. Its low-noise adaptor alongside the optimised fan design allows it to operate quietly while still providing adequate cooling. Users looking for a whisper-quiet CPU cooler may find the NH-U9S to be a better fit, especially in environments where noise is a critical factor.

Compatibility

The Thermalright Peerless Assassin 120 boasts a height of 162mm, making it compatible with a wide range of mainstream ATX chassis. Its dual-tower design allows ample space for high-capacity memory and graphics cards, ensuring compatibility with various builds. Additionally, its installation does not present significant challenges, making it accessible for a broad audience.

In contrast, the Noctua NH-U9S is specifically designed for smaller builds. Its 125mm height means it is ideal for compact systems like HTPCs and ITX builds. It is compatible with multiple Intel and AMD sockets, including LGA1851, LGA1700, LGA1200, LGA115x, and AMD AM5 & AM4, making it versatile in terms of CPU compatibility.

Installation Process

Both coolers offer user-friendly installation processes, but they differ in complexity. The Thermalright Peerless Assassin 120 comes with a straightforward mounting system that allows for easy setup, especially for users familiar with PC building. Its dual-fan design might require a bit more attention during installation, but overall, it is designed to be accessible.

In comparison, the Noctua NH-U9S is backed by its renowned SecuFirm2 mounting system, which ensures a secure and straightforward installation process. It includes high-end NT-H1 thermal paste, aiding in optimal thermal conductivity. This makes the NH-U9S an attractive option for those who prefer a no-fuss installation experience.

Brand Reputation

Thermalright has established itself as a brand known for quality and performance in the cooling market. The Peerless Assassin 120 reflects this commitment, showcasing innovative features like the digital ARGB and dual fans, which appeal to modern users looking for both aesthetics and functionality.

Noctua, on the other hand, is lauded for its commitment to silent operation and reliability. With a six-year manufacturer’s warranty, the NH-U9S exemplifies Noctua's reputation for durability and performance, making it a popular choice among enthusiasts who value long-term reliability in their components.

Which should you buy?

Choosing between the Thermalright Peerless Assassin 120 Digital ARGB Black and the Noctua NH-U9S ultimately depends on your specific needs and preferences. If you seek a cooler that combines effective cooling performance with aesthetic appeal, the Thermalright model at C$62.90 is an excellent choice. However, if your priority is a compact, quieter solution for a small form factor build, the Noctua NH-U9S at C$74.95 stands out as the ideal option. Each cooler has its strengths, so consider your build requirements and preferences before making a decision.
