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

Price Comparison

The Noctua NH-U12S Redux is priced at C$62.95, while the Thermalright Peerless Assassin 120 Black is more affordable at C$54.90. This C$8.05 difference in price makes the Thermalright a more attractive option for budget-conscious consumers. While Noctua is renowned for its quality, the lower price of the Peerless Assassin may appeal to those looking for good performance without breaking the bank.

Cooling Performance

When it comes to cooling performance, the Thermalright Peerless Assassin boasts a dual-tower design with an effective heat dissipation area of 9600 cm². This configuration is designed for superior cooling efficiency, particularly during heavy workloads. In contrast, the Noctua NH-U12S Redux features a slim 120mm size that excels in compatibility with most tower cases and does not block RAM slots or PCIe slots. However, it relies on a single fan, which may not provide the same level of cooling as the dual-fan setup of the Thermalright.

Fan Technology

The Noctua NH-U12S Redux is equipped with an NF-P12 redux-1700 fan that operates quietly and features PWM for automatic speed control. This design ensures full cooling performance under load while remaining nearly silent at idle. The Thermalright Peerless Assassin, however, comes with two PWM fans that can achieve a maximum airflow of 66.17 CFM at 1500 RPM, which may translate to better overall cooling performance. Both fans aim for low noise levels, but the dual-fan design of the Thermalright could provide an edge in heat dissipation.

Installation Process

For ease of installation, the Noctua NH-U12S Redux includes the SecuFirm2 mounting system along with high-end NT-H1 thermal paste. This streamlined installation process is compatible with various Intel and AMD sockets, making it versatile for many builds. The Thermalright Peerless Assassin also supports a wide range of Intel and AMD sockets and features metal fasteners for stability. However, the inclusion of thermal paste in the Noctua package could simplify the installation for first-time builders.

Build Quality

Noctua is well-known for its high-quality products, and the NH-U12S Redux is no exception. The brand's reputation for reliability and performance is a significant selling point. The Thermalright Peerless Assassin utilizes a full electroplating reflow welding process for its construction, which is designed to enhance durability. While both products exhibit solid build quality, Noctua may have the upper hand due to its long-standing reputation in the cooling market.

Compatibility

The Noctua NH-U12S Redux is designed to fit most tower cases with a height of 158mm, ensuring that it does not interfere with RAM slots or PCIe lanes on most ATX and Micro-ATX motherboards. The Thermalright Peerless Assassin, with dimensions of 125mm x 135mm x 157mm, also fits a wide range of cases and allows for installation on the first graphics card slot. Both coolers are compatible with a variety of CPU sockets, making them suitable for diverse builds.

Noise Levels

The Noctua NH-U12S Redux operates quietly, particularly at idle, thanks to its advanced fan design. The Thermalright Peerless Assassin is rated for a maximum noise level of 25.6 dB(A), which is competitive for a cooler with dual fans. While both coolers are designed to minimize noise, the single-fan setup of the Noctua may offer a quieter operation under light loads. However, the Thermalright’s dual fans could provide better cooling without significantly increasing noise levels.

Which should you buy?

Ultimately, the choice between the Noctua NH-U12S Redux and the Thermalright Peerless Assassin 120 Black comes down to your specific needs. If you prioritize a reputable brand with a focus on quiet operation and excellent compatibility, the Noctua is a smart choice. However, if you are looking for superior cooling performance at a lower price, the Thermalright Peerless Assassin offers an attractive alternative. Both coolers have their strengths, so consider your budget and cooling requirements before making a decision.
