Thermalright Assassin X 120 V2 Plus CPU Cooler 4 Heat Pipes with AGHP Technology vs Noctua NH-U9S

Overview of the Thermalright Assassin X 120 V2 Plus and Noctua NH-U9S

The Thermalright Assassin X 120 V2 Plus and the Noctua NH-U9S are both notable CPU coolers, each catering to different needs in the PC building landscape. The Thermalright model is priced at C$25.90, while the Noctua model retails for a significantly higher C$74.95. This price difference reflects varying design philosophies and target markets, which will be explored in detail.

Design and Build Quality

The Thermalright Assassin X 120 V2 Plus features a compact design measuring 120(L)x96(W)x154(H)mm, making it suitable for a variety of builds. Its four heat pipes utilize AGHP technology to enhance cooling performance, addressing issues related to orientation. In contrast, the Noctua NH-U9S is a single-tower cooler with a height of only 125mm, designed for tight spaces like HTPCs and small form factor builds. This height ensures it does not overhang RAM or PCIe slots on most motherboards, providing flexibility in case design.

Cooling Performance

The Thermalright Assassin X 120 V2 Plus is equipped with four 6mm heat pipes that promote effective heat dissipation, making it a robust option for high-performance CPUs. Its S-FDB bearings contribute to a quieter operation while maintaining maximum cooling capabilities. The Noctua NH-U9S, on the other hand, utilises a highly optimised NF-A9 92mm fan that supports PWM for automatic speed control, ensuring ultra-quiet operation even under load. While both coolers are effective, their performance may vary based on individual use cases and configurations.

Compatibility and Installation

The Thermalright Assassin X 120 V2 Plus supports a wide range of CPU sockets, including Intel's 1150/1151/1155/1156/1200/1700 and AMD's AM4/AM5 sockets. It comes with metal fasteners tailored for these platforms, alongside installation videos for guidance. The Noctua NH-U9S also boasts broad compatibility, supporting Intel LGA1851, LGA1700, LGA1200, LGA115x, and AMD AM4/AM5 sockets. It includes the SecuFirm2 mounting system for straightforward installation, making both coolers user-friendly.

Noise Levels

One of the standout features of the Thermalright Assassin X 120 V2 Plus is its focus on minimal noise, thanks to its quality S-FDB bearings. This design helps in reducing vibration and blade shaking, allowing for a quieter operation during intense tasks. The Noctua NH-U9S is renowned for its ultra-quiet operation, aided by the Low-Noise Adaptor that can automatically control fan speeds. Both coolers prioritise low noise levels, but the Noctua's reputation in this area may appeal more to users seeking silent operation.

Cooling Technology

The Thermalright Assassin X 120 V2 Plus employs advanced AGHP technology, which helps mitigate the inverse gravity effect that can affect cooling performance in various orientations. This technology ensures that the cooler maintains efficiency regardless of its installation position. The Noctua NH-U9S features a highly optimised fan that not only delivers excellent airflow but also promises durability, backed by a 6-year manufacturer’s warranty. While both coolers leverage innovative technologies, the Thermalright’s AGHP technique may provide a slight edge in versatility.

Price and Value

The Thermalright Assassin X 120 V2 Plus is priced at a budget-friendly C$25.90, making it an attractive option for those looking to save costs without sacrificing performance. In contrast, the Noctua NH-U9S is significantly more expensive at C$74.95, reflecting its premium build quality and brand reputation. While the Noctua offers extensive features and reliability, the Thermalright cooler provides excellent value for users on a budget.

Which should you buy?

Choosing between the Thermalright Assassin X 120 V2 Plus and the Noctua NH-U9S ultimately depends on your specific needs and budget. If you seek an affordable cooler that provides solid performance and versatility, the Thermalright model is an excellent choice at C$25.90. However, if you prioritise top-notch quiet operation, high-quality components, and a well-established brand, the Noctua NH-U9S, despite its higher price of C$74.95, is likely the better option. Consider your system requirements, budget, and cooling expectations before making a decision.
