Noctua NH-U12S Redux vs Thermalright Peerless Assassin 120 SE V2 CPU Cooler

Overview of the Coolers

When comparing the Noctua NH-U12S Redux and the Thermalright Peerless Assassin 120 SE V2, it's essential to consider their price points and overall performance. The Noctua model is priced at C$62.95, while the Thermalright cooler is slightly more affordable at C$54.90. Both coolers are designed to provide efficient CPU cooling, but their features and specifications cater to different user needs.

Design and Compatibility

The Noctua NH-U12S Redux features a streamlined design that fits most tower cases, measuring 158mm in height. This cooler is compatible with a range of Intel and AMD sockets, including LGA1851, LGA1700, LGA1200, and AM4. In contrast, the Thermalright Peerless Assassin has dimensions of 125mm x 135mm x 155mm, making it slightly bulkier but still manageable for most builds. It supports Intel LGA 1851, 1700, 1200, and AMD AM4/AM5, offering broad compatibility as well. Both coolers are designed to avoid overhanging RAM slots and blocking PCIe slots, making them suitable for various setups.

Cooling Performance

The cooling performance of these two coolers can be distinguished by their fan specifications. The Noctua NH-U12S Redux is equipped with a quiet NF-P12 redux-1700 fan, which operates efficiently at PWM-controlled speeds, providing full cooling performance under load while remaining near silent at idle. The Thermalright Peerless Assassin features dual 120mm PWM fans with a maximum speed of 1850 RPM, offering an airflow of 88.19 CFM. While both coolers are designed for effective cooling, the Thermalright model boasts higher airflow, potentially making it better for high-performance CPUs.

Noise Levels

Noise levels are a critical consideration for users seeking a quiet operation. The Noctua NH-U12S Redux is known for its quiet performance, particularly at idle, thanks to its advanced fan design. Although the specific noise level is not stated, it is typically regarded as one of the quieter options on the market. The Thermalright Peerless Assassin has a maximum noise level of 29.5 dB(A), which is relatively quiet but may be more noticeable under load compared to the Noctua. For users prioritising silence, the Noctua may have the edge.

Installation and Ease of Use

Both coolers offer user-friendly installation processes. The Noctua NH-U12S Redux includes the high-end NT-H1 thermal paste and a SecuFirm2 mounting system, simplifying the installation on various Intel and AMD platforms. The Thermalright Peerless Assassin also comes with the necessary metal fasteners and installation instructions for both Intel and AMD CPU sockets, ensuring compatibility and ease of setup. While both coolers provide a straightforward installation experience, Noctua's renowned quality and included thermal paste could appeal to users looking for a hassle-free setup.

Build Quality and Durability

Build quality is a hallmark of both brands, but they have distinct approaches. The Noctua NH-U12S Redux is part of a redux line that retains the award-winning design of the original NH-U12S while offering a more affordable price. This cooler is known for its reliability and longevity. The Thermalright Peerless Assassin features an aluminum fin design with a pure copper base, highlighting its robust construction. With 6 heat pipes utilizing GEN 5.0 technology, it aims for exceptional thermal performance. While both coolers exhibit high-quality materials, Noctua's reputation for durability may give it a slight advantage.

Price vs. Performance

When looking at price versus performance, the Noctua NH-U12S Redux is more expensive at C$62.95 compared to the Thermalright Peerless Assassin at C$54.90. However, the Noctua cooler is often praised for its superior quiet operation and build quality, which can justify the higher price for some users. The Thermalright cooler, while less expensive, offers excellent performance and airflow, making it an attractive option for budget-conscious buyers. Ultimately, the choice may depend on how much weight a user places on quiet operation and build quality versus raw cooling performance.

Which should you buy?

Choosing between the Noctua NH-U12S Redux and the Thermalright Peerless Assassin 120 SE V2 ultimately depends on your specific needs and preferences. If you prioritise a quieter operation and superior build quality, the Noctua is a solid choice despite its higher price. However, if you are looking for a more budget-friendly option that still delivers strong cooling performance, the Thermalright model is an excellent alternative. Consider your system compatibility, desired noise levels, and overall budget to make the best decision for your CPU cooling needs.
