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

Price Comparison

When comparing the Thermalright Peerless Assassin 120 and the Noctua NH-U12S, the price is a significant factor. The Peerless Assassin 120 is priced at C$51.39, making it a budget-friendly option. In contrast, the Noctua NH-U12S comes at a higher price of C$79.95. This difference of C$28.56 may reflect the additional features and brand reputation associated with Noctua, known for its premium cooling solutions. Buyers on a tighter budget might lean towards the Thermalright, while those willing to invest more for perceived quality may opt for the Noctua.

Cooling Performance

Cooling performance is a crucial consideration for any CPU cooler. The Thermalright Peerless Assassin 120 boasts an effective heat dissipation area of 9600cm², which is substantial for maintaining optimal CPU temperatures. It features a TDP rating of 245W, indicating its capability to handle high-performance CPUs effectively. On the other hand, the Noctua NH-U12S, while not providing a specific TDP rating, is designed with a slim-tower configuration that combines excellent cooling with case and RAM compatibility. Users can expect impressive performance from both coolers, but the Thermalright may have the edge in raw cooling capacity.

Design and Dimensions

In terms of design and dimensions, the Thermalright Peerless Assassin 120 measures 125mm in length, 135mm in width, and 157mm in height. It features a twin-tower design that allows for efficient airflow and heat dissipation. Conversely, the Noctua NH-U12S utilises a classic slim-tower design that enhances compatibility with various cases and components, ensuring it does not overhang RAM or PCIe slots on most motherboards. This design consideration makes the Noctua an appealing choice for those with compact builds, while the Thermalright's larger dimensions may favour users seeking maximum cooling performance.

Fan Technology

Fan technology plays a pivotal role in the overall functionality of CPU coolers. The Thermalright Peerless Assassin 120 incorporates two PWM fans, each with a maximum speed of 1500 RPM and a noise level of ≤25.6 dB(A). This dual-fan setup provides a high airflow rate of 66.17 CFM, contributing to its strong cooling performance. The Noctua NH-U12S is equipped with the renowned NF-F12 120mm Focused Flow fan, which is optimised for low-noise operation. It includes a Low-Noise Adaptor for automatic speed control, ensuring quiet performance. While both coolers deliver effective cooling, the Thermalright’s dual fans may offer superior airflow, whereas Noctua excels in noise management.

Installation and Compatibility

Installation and compatibility are essential for easy setup and performance. The Thermalright Peerless Assassin 120 supports a wide range of Intel and AMD sockets, including Intel's LGA 1150 through 1700 and AMD’s AM4 and AM5. It comes with metal fasteners designed for easy installation. The Noctua NH-U12S also features broad compatibility with sockets including Intel LGA 115x, LGA 1200, LGA 1700, and AMD AM4 and AM5. It provides a SecuFirm2 mounting system that simplifies installation. Both coolers excel in this category, but users should verify compatibility with their specific motherboard before making a purchase.

Aesthetics and RGB Lighting

Aesthetics can be an important aspect for gamers and PC builders. The Thermalright Peerless Assassin 120 features colourful ARGB lighting effects, allowing users to customise their build’s look with synchronised lighting through the motherboard. This can enhance the overall visual appeal of a gaming rig. In contrast, the Noctua NH-U12S opts for a more understated, classic design without RGB lighting. While it may not have the flashy features of the Thermalright, Noctua’s reputation for quality and performance can appeal to users prioritising functionality over aesthetics.

Noise Levels

Noise levels are a critical factor for many users, especially in quiet environments. The Thermalright Peerless Assassin 120 operates at a maximum noise level of ≤25.6 dB(A), which is relatively quiet for its performance level. The Noctua NH-U12S is known for its ultra-quiet operation, enhanced by its Low-Noise Adaptor that further reduces noise during operation. While both coolers are designed to operate quietly, Noctua’s emphasis on low-noise technology may make it the better choice for users who prioritise a silent computing experience.

Which should you buy?

Ultimately, the choice between the Thermalright Peerless Assassin 120 and the Noctua NH-U12S depends on your specific needs and budget. If you are looking for a cost-effective solution with robust cooling performance and RGB aesthetics, the Thermalright Peerless Assassin 120 is an excellent option at C$51.39. However, if you prefer a premium cooler with a strong reputation for quiet operation and reliability, the Noctua NH-U12S, despite its higher price of C$79.95, could be the better investment. Consider your priorities, whether they be cost, cooling performance, or noise levels, to make the best decision for your build.
