Noctua NH-L12S vs Thermalright Peerless Assassin 120 Black CPU Air Cooler

Price Comparison

When it comes to pricing, the Thermalright Peerless Assassin 120 Black CPU Air Cooler is significantly more affordable at C$54.90 compared to the Noctua NH-L12S, which is priced at C$87.95. This represents a difference of C$33.05, making the Peerless Assassin a budget-friendly option for those looking to enhance their CPU cooling without breaking the bank. The lower price of the Peerless Assassin does not necessarily compromise its performance, as it offers excellent cooling capabilities, but potential buyers should weigh the cost against their cooling needs and system compatibility.

Design and Build Quality

The Noctua NH-L12S features a compact and premium-quality design with a total height of just 70mm, making it ideal for smaller ITX and HTPC systems. Its low-profile design is particularly beneficial in tight spaces. In contrast, the Thermalright Peerless Assassin boasts a more substantial build, featuring a double tower design that measures 125mm in length, 135mm in width, and 157mm in height. This design allows for a greater heat dissipation area of 9600cm, which could contribute to better overall cooling performance. While Noctua is known for its high-quality materials, the Thermalright’s use of a full electroplating reflow welding process adds to its robust construction.

Cooling Performance

The Thermalright Peerless Assassin excels in cooling performance with its dual PWM fans, which can reach a fan speed of 1500 RPM and provide an airflow of 66.17 CFM. This dual-fan setup allows for effective heat dissipation, making it suitable for demanding CPU loads. On the other hand, the Noctua NH-L12S utilises a highly optimised NF-A12x15 120mm fan designed for ultra-quiet operation. While the NH-L12S is noted for its low noise levels and efficient cooling, the sheer airflow capability of the Peerless Assassin might give it an edge in scenarios where maximum cooling is required.

Installation and Compatibility

Both the Noctua NH-L12S and the Thermalright Peerless Assassin are designed for easy installation and broad compatibility with various CPU sockets. The NH-L12S comes equipped with the SecuFirm2 mounting system and supports Intel sockets like LGA1851, LGA1700, and several AMD sockets, including AM5 and AM4. Conversely, the Peerless Assassin offers compatibility with an extensive range of Intel sockets (LGA1150 through LGA2066) and AMD platforms (AM4, AM5). While both coolers provide ample compatibility, the variety of supported sockets in the Peerless Assassin may appeal to users with diverse setups.

Noise Levels

The Noctua NH-L12S stands out for its ultra-quiet operation, thanks to its low-noise adaptor that allows for automatic speed control. This cooler is designed to operate quietly, which is an essential factor for users who prioritise a silent computing experience. The Thermalright Peerless Assassin, while equipped with dual fans, claims a maximum noise level of 25.6 dB(A). Although this level is relatively quiet, it may not match the whisper-quiet operation of the NH-L12S. Therefore, for users sensitive to noise, the Noctua may be the preferable option.

Thermal Performance

In terms of thermal performance, the Thermalright Peerless Assassin’s design and dual fan setup suggest it can handle higher thermal loads effectively. The combination of six heat pipes and the AGHP technique enables it to maintain efficient cooling even in vertical or horizontal orientations. The Noctua NH-L12S, while designed for moderate heat loads, is particularly suited for CPUs like the Intel 285K and AMD Ryzen 7950X3D. Users with CPUs that generate moderate heat will find the NH-L12S to be a reliable choice, but those with more demanding processors may benefit from the increased thermal capacity of the Peerless Assassin.

Aesthetics

Aesthetics can play a significant role in a user’s choice of CPU cooler. The Noctua NH-L12S maintains a classic and understated design that aligns well with various PC builds, especially in minimalist setups. On the other hand, the Thermalright Peerless Assassin features a sleek black finish, which could appeal to users looking for a more modern and aggressive appearance. The visual choice between the two will largely depend on personal preference, as both coolers offer a distinct style that can complement different builds.

Which should you buy?

Choosing between the Noctua NH-L12S and the Thermalright Peerless Assassin 120 Black ultimately depends on your specific needs and budget. If you're looking for a compact, quiet, and high-quality cooler for a system with moderate heat output, the Noctua NH-L12S is an excellent choice, albeit at a higher price of C$87.95. However, if budget is a primary concern and you require robust cooling performance for a demanding CPU setup, the Thermalright Peerless Assassin at C$54.90 offers great value with its dual fans and extensive compatibility. Consider your CPU’s thermal requirements, your system's size, and your noise tolerance when making your decision.
