Thermalright Peerless Assassin 120 SE V2 CPU Cooler vs Noctua NH-U9S

Overview of Thermalright Peerless Assassin 120 SE V2 and Noctua NH-U9S

The Thermalright Peerless Assassin 120 SE V2 and Noctua NH-U9S are both high-performance CPU coolers, but they cater to slightly different needs and preferences. The Thermalright model is priced at C$54.90, while the Noctua option comes in at C$74.95. This price difference of C$20.00 indicates that while both products provide excellent cooling capabilities, the features and design may justify the higher cost of the Noctua cooler.

Design and Compatibility

The Thermalright Peerless Assassin 120 SE V2 features a dual-tower design measuring 125mm in width, 135mm in depth, and 155mm in height. This cooler is built with aluminum fins and a copper base, ensuring effective heat dissipation. It is designed to support various Intel and AMD socket types, including LGA 1851, LGA 1700, AM4, and AM5, making it versatile for most modern builds. On the other hand, the Noctua NH-U9S sports a more compact single-tower design with a height of only 125mm, ideal for HTPCs and small form factor builds. It also supports a wide range of sockets, including Intel LGA 1851, LGA 1700, LGA 1200, and AMD AM4 and AM5, ensuring compatibility with many CPUs.

Cooling Performance

In terms of cooling performance, the Thermalright Peerless Assassin 120 SE V2 is equipped with six 6mm heat pipes and can handle a thermal design power (TDP) of up to 265W. This makes it suitable for high-performance CPUs, especially in gaming or workstation environments. Conversely, the Noctua NH-U9S is designed with a 92mm fan, which, while smaller, offers an excellent balance of cooling efficiency and quiet operation. It is renowned for its ability to provide strong cooling performance without the noise, making it an attractive option for users prioritizing a quieter system.

Noise Levels

The Thermalright Peerless Assassin 120 SE V2 operates at a maximum noise level of 29.5 dB(A), which is relatively quiet for a CPU cooler of its size and performance. This dB rating indicates that it should be suitable for users who require a quieter computing experience. In contrast, the Noctua NH-U9S is also engineered for low noise, utilising a specially optimised fan that supports PWM and comes with a low-noise adapter. While specific noise levels are not provided, Noctua is known for its ultra-quiet operation, making this cooler an excellent choice for silent builds.

Fan Specifications

The Thermalright Peerless Assassin 120 SE V2 comes with two 120mm fans that can spin up to 1850 RPM, delivering an airflow of 88.19 CFM at maximum performance. This dual-fan setup enhances its cooling efficiency, particularly under heavy loads. On the other hand, the Noctua NH-U9S features a single NF-A9 92mm fan that is highly praised for its performance and quietness. Although the fan size is smaller, Noctua’s engineering allows it to provide excellent cooling while maintaining a low noise profile, catering to users who may have space constraints.

Installation and Ease of Use

Both coolers are designed for easy installation. The Thermalright Peerless Assassin 120 SE V2 includes metal fasteners for Intel and AMD platforms, ensuring a straightforward setup process. The mounting system is compatible with various CPU socket types, which adds to its versatility. The Noctua NH-U9S also features the SecuFirm2 mounting system, which is known for its reliability and ease of use. It comes with high-end NT-H1 thermal paste, simplifying the installation process for users new to CPU cooler setups.

Brand Reputation and Warranty

Thermalright has built a reputation for providing solid performance at competitive prices, with the Peerless Assassin 120 SE V2 being no exception. However, it does not specify a warranty period in the provided data. In contrast, Noctua is renowned for its quality and offers a generous 6-year manufacturer’s warranty for the NH-U9S. This long warranty period reflects the brand's confidence in its product and serves as an assurance for buyers seeking reliability.

Which should you buy?

Choosing between the Thermalright Peerless Assassin 120 SE V2 and the Noctua NH-U9S ultimately depends on your specific needs and preferences. If you are looking for a powerful, budget-friendly cooler capable of handling high TDPs and do not mind the larger footprint, the Thermalright model at C$54.90 is an excellent choice. However, if you prioritise a quieter operation, a compact design, and a strong brand reputation, the Noctua NH-U9S, priced at C$74.95, may be worth the extra investment. Each cooler excels in its own right, making the decision largely dependent on whether performance or noise levels take precedence in your build.
