Thermalright Assassin X 120R SE Plus CPU Cooler - 4×6mm Heat Pipes vs Noctua NH-U9S

Overview of the Products

When comparing the Thermalright Assassin X 120R SE Plus and the Noctua NH-U9S, it's important to note that both CPU coolers cater to specific needs and preferences. The Thermalright cooler is priced at C$25.59, while the Noctua unit is significantly higher at C$74.95. This price disparity may reflect differences in design, performance, and additional features that appeal to different segments of the market.

The Thermalright Assassin X 120R SE Plus boasts a double PWM fan system designed to provide efficient cooling with a noise level of no more than 25.6 dB(A). On the other hand, the Noctua NH-U9S features a compact single-tower design ideal for smaller builds, making it particularly suited for HTPCs and small form factor systems.

Design and Compatibility

The Thermalright Assassin X 120R SE Plus features a dual-fan design with a standard size of 120x120x25mm, making it a versatile choice for various cases. It supports multiple CPU socket platforms, including Intel's LGA 1700 and AMD's AM4/AM5, ensuring broad compatibility.

Conversely, the Noctua NH-U9S has a compact height of only 125mm, which is beneficial for builds that are constrained by space. Its design prevents overhanging on RAM or PCIe slots, which can be a significant advantage for users with tight builds. Both coolers are designed for ease of installation, with the Noctua featuring the SecuFirm2 mounting system, while Thermalright also provides specific mounting plates for various CPU sockets.

Cooling Performance

Cooling performance is a crucial factor when choosing a CPU cooler, and both units position themselves well in this regard. The Thermalright Assassin X 120R SE Plus utilises four 6mm heat pipes and claims an industrial service life of up to 20,000 hours, which indicates a focus on long-term reliability.

In contrast, the Noctua NH-U9S incorporates a highly optimised NF-A9 92mm fan, which is equipped with PWM support and a Low-Noise Adaptor for automatic speed control. This design enhances its cooling efficiency, particularly in compact builds. While specific cooling performance metrics aren’t detailed, both products have been engineered to provide effective thermal management, tailored for different use cases.

Noise Levels

When it comes to noise levels, the Thermalright Assassin X 120R SE Plus operates at a maximum noise level of 25.6 dB(A), ensuring a relatively quiet environment during operation. This is particularly important for users who prioritise a silent computing experience.

The Noctua NH-U9S, while also designed for quiet operation, does not specify a maximum noise level in the provided data. However, Noctua is renowned for its focus on low-noise operation, suggesting that it is likely to perform similarly in terms of noise output. Users seeking silence alongside cooling performance will find both options appealing, though the Thermalright provides a clear numerical reference.

Build Quality and Longevity

Build quality can significantly influence a cooler's performance and longevity. The Thermalright Assassin X 120R SE Plus uses high-quality materials such as industrial-strength PBT + PC, enhancing its durability. The inclusion of S-FDB bearings also contributes to the cooling fan's longevity, reducing blade shaking and noise.

On the other hand, the Noctua NH-U9S is backed by a six-year manufacturer's warranty, indicating strong confidence in its durability and performance. It also includes high-end NT-H1 thermal paste, further ensuring optimal thermal transfer between the CPU and cooler. Both models reflect a commitment to quality, but Noctua's warranty stands out as a testament to its reliability.

Installation Process

The installation process of a CPU cooler can greatly impact the user experience, and both the Thermalright Assassin X 120R SE Plus and Noctua NH-U9S are designed with user-friendliness in mind. The Thermalright cooler includes specific mounting plates and fasteners for various CPU socket platforms, streamlining the installation process for users.

The Noctua NH-U9S features the SecuFirm2 mounting system, which is known for its straightforward and secure installation. This system is compatible with a range of Intel and AMD sockets, minimizing potential compatibility issues. While both coolers promote easy installation, Noctua’s reputation for user-friendly setups may provide an additional edge for less experienced builders.

Price Point

Price is often a decisive factor for consumers, and in this comparison, the Thermalright Assassin X 120R SE Plus is significantly more affordable at C$25.59. This lower price point makes it an attractive option for budget-conscious users or those seeking a cost-effective cooling solution.

In contrast, the Noctua NH-U9S is priced at C$74.95, reflecting its premium positioning in the market. The higher cost may be justified by its advanced features, build quality, and brand reputation. Users should consider whether the additional investment in the Noctua cooler aligns with their specific needs and performance expectations.

Which should you buy?

Ultimately, the choice between the Thermalright Assassin X 120R SE Plus and the Noctua NH-U9S depends on your specific requirements and budget. If you seek an affordable, effective cooling solution for a variety of builds, the Thermalright cooler is an excellent choice with its dual-fan design and broad compatibility.

Conversely, if you are looking for a premium product with a compact design, exceptional build quality, and a strong brand reputation, the Noctua NH-U9S may justify its higher price. Both coolers deliver reliable performance, but the decision should hinge on your individual priorities regarding price, size, and specific cooling needs.
