Thermalright Assassin X 90 SE V2 CPU Cooler vs Noctua NH-U9S

Overview of the Thermalright Assassin X 90 SE V2 and Noctua NH-U9S

The Thermalright Assassin X 90 SE V2 is priced at C$24.90, while the Noctua NH-U9S has a higher price tag of C$74.95. Despite the price difference, both CPU coolers offer unique features that cater to different needs.

The Thermalright brand has built a reputation over 20 years for producing reliable cooling solutions. The Assassin X 90 SE V2 utilises advanced AGHP technology, which includes a 4x6mm heatpipe designed to enhance cooling performance. In contrast, Noctua is celebrated for its premium products and the NH-U9S showcases an efficient design that is especially suitable for compact builds. Each cooler stands out in its own right, making the choice dependent on your specific requirements.

Design and Size Comparison

The design and size of a CPU cooler can significantly impact compatibility and aesthetics in a build. The Thermalright Assassin X 90 SE V2 dimensions are 94(L)x77(W)x118(H)mm, allowing it to fit into a wide range of chassis models. Conversely, the Noctua NH-U9S is designed with a compact single-tower structure and measures only 125mm in height. This makes the NH-U9S ideal for HTPCs and small form factor builds, ensuring that it does not overhang RAM or PCIe slots on most motherboards.

While the Thermalright cooler is slightly shorter in overall height, the Noctua's compact design provides a distinct advantage in tight spaces, making it a better choice for users with space constraints. Thus, while both coolers are well engineered, their designs cater to different build environments.

Cooling Performance

Cooling performance is a crucial factor when selecting a CPU cooler. The Thermalright Assassin X 90 SE V2 features a PWM fan that operates at a maximum speed of 2200 RPM, generating an airflow of 32.77 CFM and maintaining a noise level of 23.85 dB(A). This level of performance is supported by its advanced heatpipe technology and industrial-grade materials, ensuring effective heat dissipation.

On the other hand, the Noctua NH-U9S comes equipped with a highly optimised NF-A9 92mm fan, which also offers PWM support and is designed for ultra-quiet operation, particularly when combined with the Low-Noise Adaptor. While specific airflow figures are not provided for the NH-U9S, it is known for its strong cooling performance in compact environments.

Both coolers excel in cooling efficiency, but the Thermalright offers higher RPM and airflow, which may be preferable for users seeking maximum cooling potential, especially in higher performance environments.

Noise Levels

Noise levels are an important consideration for users who prioritise a quiet computing experience. The Thermalright Assassin X 90 SE V2 operates at a maximum noise level of 23.85 dB(A). This is relatively quiet for a cooler that operates at such high RPMs, making it suitable for gaming or workstation setups where noise could be a distraction.

The Noctua NH-U9S is specifically designed for low-noise operation, aided by its PWM fan and the inclusion of a Low-Noise Adaptor. While the exact noise level is not specified, Noctua's reputation for quiet performance suggests it will be very competitive in this area.

In summary, while both coolers aim for quiet operation, the Thermalright has a measurable noise output, whereas the Noctua is designed to be quieter, which could sway users who are particularly sensitive to noise.

Compatibility

Compatibility with various CPU sockets is essential for ensuring that a cooler can fit a wide range of builds. The Thermalright Assassin X 90 SE V2 supports a broad spectrum of CPU cooling slots, including Intel's 1150/1151/1155/1156/1200 and AMD's AM4/AM5. This flexibility means it can be used with many current processor models.

The Noctua NH-U9S also has extensive compatibility with Intel LGA1851, LGA1700, LGA1200, LGA115x, and AMD AM5 & AM4. It features an offset mounting option for optimal efficiency. Both coolers provide good compatibility, but the Thermalright's broader range of supported Intel sockets may appeal to users with older systems.

Installation Process

The ease of installation can greatly affect user experience, especially for those who may not be familiar with building PCs. The Thermalright Assassin X 90 SE V2 includes mounting plates and fasteners for different CPU socket platforms, along with installation instructions to guide users through the process.

Similarly, the Noctua NH-U9S comes with a SecuFirm2 mounting system that simplifies the installation process and ensures a secure fit. This system has been well-regarded for its straightforward assembly, which can be beneficial for users new to PC building.

Both coolers are designed with user-friendliness in mind, but the Noctua's reputation for a hassle-free installation process may give it an edge for novice builders.

Brand Reputation

Brand reputation can influence purchasing decisions significantly. Thermalright has over two decades of experience in the cooler market, providing a solid foundation of trust among users. The brand has consistently delivered reliable products that meet user expectations.

Noctua, on the other hand, is often viewed as the premium choice in cooling solutions, known for its high-quality materials, innovative designs, and superior performance. The NH-U9S is backed by a 6-year manufacturer's warranty, further establishing Noctua's commitment to quality and customer satisfaction.

The choice between these brands may ultimately come down to personal preference, but Noctua’s established reputation for excellence may appeal to those looking for a premium product.

Which should you buy?

Ultimately, choosing between the Thermalright Assassin X 90 SE V2 and the Noctua NH-U9S boils down to your specific needs and preferences. If you are looking for a cost-effective solution with excellent cooling performance and broad compatibility, the Thermalright Assassin X 90 SE V2 at C$24.90 is a compelling choice. However, if you prioritize a compact design, ultra-quiet operation, and a premium brand reputation, the Noctua NH-U9S, priced at C$74.95, may be worth the extra investment. Each cooler has its strengths, so consider your build requirements and personal preferences carefully before making a decision.
