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

Pricing Comparison

When it comes to pricing, the Thermalright Peerless Assassin 120 is the more economical choice at C$51.39, while the Noctua NH-U12S Redux is priced at C$62.95. This represents a difference of C$11.56, making the Thermalright cooler the budget-friendly option for consumers looking to keep costs down. Given that both coolers offer excellent performance, the price difference could influence buying decisions, especially for those on a tighter budget or looking for cost-effective cooling solutions.

Design and Build Quality

The Noctua NH-U12S Redux features a slim 120mm size, allowing for excellent compatibility with most tower cases, RAM, and PCIe slots. Standing at 158mm in height, this cooler is designed to avoid blocking RAM slots and fits comfortably in most ATX and Micro-ATX motherboards. In contrast, the Thermalright Peerless Assassin 120 has a double tower design that measures 125mm in length, 135mm in width, and 157mm in height. Its offset asymmetric layout allows for installation without obstruction, giving it an advantage in tight spaces. Both coolers showcase quality materials, but Noctua’s reputation for durability may appeal to users prioritizing longevity.

Cooling Performance

In terms of cooling capabilities, the Thermalright Peerless Assassin 120 boasts an impressive TDP of 245W, indicating its ability to handle high-performance CPUs. Its design includes six pure copper sintered heat pipes that enhance heat dissipation efficiency. Meanwhile, the Noctua NH-U12S Redux is part of the acclaimed redux line and offers effective cooling with its NF-P12 redux-1700 fan, ensuring that it operates quietly at idle while ramping up performance under load. While both coolers excel in cooling performance, the Thermalright may have the upper hand for users with higher TDP CPUs.

Noise Levels

The Noctua NH-U12S Redux is engineered for near-silent operation, particularly at idle, thanks to its quiet fan design. This is a significant consideration for users who prioritize a low-noise environment, such as gamers or professionals working in sound-sensitive areas. On the other hand, the Thermalright Peerless Assassin 120 operates at a noise level of ≤25.6dB(A) at maximum fan speed. While the Thermalright is relatively quiet, it may not match the near-silent performance of the Noctua model. Thus, for users sensitive to noise, the Noctua is likely the better option.

Fan Features

The Noctua NH-U12S Redux comes equipped with a single NF-P12 redux-1700 fan that allows for automatic speed control through PWM, ensuring optimal performance under various loads. This feature is particularly beneficial for users who want a hassle-free cooling experience without constant manual adjustments. Meanwhile, the Thermalright Peerless Assassin 120 includes two PWM fans, which not only enhance airflow but also feature colourful ARGB lighting effects for those who enjoy illuminated PC builds. While both coolers offer PWM functionality, the dual-fan setup of the Thermalright could provide better cooling at the cost of increased noise during peak performance.

Installation and Compatibility

Both coolers offer straightforward installation processes, but they cater to different user needs. The Noctua NH-U12S Redux includes the SecuFirm2 mounting system, which simplifies installation across various Intel and AMD sockets, including LGA1700 and AM4. This feature can especially benefit users who plan on upgrading or changing components in the future. The Thermalright Peerless Assassin 120 also supports a wide range of Intel and AMD sockets, with corresponding mounting plates included. However, its larger design may require more space and careful consideration during installation. Ultimately, both options are user-friendly, with slight advantages depending on the specific motherboard and case configuration.

Brand Reputation

Noctua has built a strong reputation in the cooling market for its premium quality and performance. Known for its durability and reliability, Noctua products are often the go-to choice for enthusiasts and professionals alike. In contrast, Thermalright has also established itself as a reputable brand, particularly with its innovative designs and competitive pricing. While both brands offer reliable products, Noctua's long-standing reputation may sway some consumers towards the NH-U12S Redux, especially those who seek proven performance and quality.

Which should you buy?

Choosing between the Noctua NH-U12S Redux and the Thermalright Peerless Assassin 120 ultimately depends on your specific needs and budget. If you are looking for a high-quality cooler with renowned silent operation and excellent compatibility, the Noctua NH-U12S Redux at C$62.95 stands out as the premium choice. However, if budget is your primary concern and you require robust cooling for a high-TDP CPU, the Thermalright Peerless Assassin 120 at C$51.39 offers compelling value with solid performance. Consider your priorities—whether it’s price, noise levels, or brand reputation—before making your final decision.
