Noctua NH-L9i-17xx vs Thermalright Assassin X 90 SE V2 CPU Cooler

Price Comparison

When comparing prices, the Thermalright Assassin X 90 SE V2 CPU Cooler is significantly more affordable at C$24.90, while the Noctua NH-L9i-17xx is priced at C$59.95. This represents a difference of C$35.05, making the Thermalright option a budget-friendly choice for consumers. Despite its lower cost, the Thermalright cooler still boasts impressive features, appealing to users who are looking for effective cooling without breaking the bank.

Brand Reputation

Noctua is renowned for its premium products, having received over 200 awards and recommendations from international hardware websites. The Noctua NH-L9i-17xx, in particular, is backed by a six-year manufacturer’s warranty, ensuring long-term reliability. On the other hand, Thermalright, while having a solid reputation with over 20 years in the market, is generally perceived as a more cost-effective brand. The choice between these brands can depend on whether you prioritise high-end performance and brand prestige or value for money.

Cooling Performance

The Noctua NH-L9i-17xx is designed for Intel’s LGA1700 and LGA1851 platforms and features the award-winning NF-A9x14 slim 92mm fan, which is known for its whisper-quiet operation and efficient cooling performance. It excels in compact spaces, with a height of only 37mm, making it suitable for small form factor cases. In contrast, the Thermalright Assassin X 90 SE V2 utilises a 92mm PWM fan with a maximum speed of 2200 RPM, delivering an airflow of 32.77 CFM and a noise level of up to 23.85 dB(A). While both coolers provide effective cooling, the Noctua's design is more tailored for silent operation under load, especially in compact builds.

Size and Compatibility

In terms of size, the Noctua NH-L9i-17xx has a compact height of 37mm, which allows it to fit in small form factor cases without obstructing RAM or PCIe slots. This makes it an excellent choice for users focusing on compact builds. The Thermalright Assassin X 90 SE V2, on the other hand, stands at 118mm tall, providing broader compatibility with various chassis but potentially limiting options in tighter setups. Both coolers support a range of Intel and AMD sockets, making them versatile choices for different builds.

Installation Ease

Installation is straightforward for both coolers, but the Noctua NH-L9i-17xx includes a SecuFirm2 mounting system designed for easy installation on Intel LGA1700 and LGA1851 CPUs. This is particularly beneficial for users who may not have extensive experience with CPU cooler installations. Conversely, the Thermalright Assassin X 90 SE V2 offers a detailed installation guide and compatibility with multiple CPU slots, which could appeal to DIY enthusiasts. However, the additional complexity may pose a challenge to less experienced users.

Material Quality

The Noctua NH-L9i-17xx boasts high-quality materials and craftsmanship, which is reflected in its award-winning design and durable performance. It includes high-end NT-H1 thermal paste, enhancing its thermal conductivity. The Thermalright Assassin X 90 SE V2 utilises industrial-grade materials, including aluminum and HDT direct touch technology, which contribute to its effective heat dissipation. While both products use quality materials, Noctua’s emphasis on premium components may provide an edge in long-term reliability.

Noise Levels

Noise levels are crucial for many PC builders, particularly those creating quiet or silent systems. The Noctua NH-L9i-17xx is designed to operate quietly, thanks to its NF-A9x14 fan, which ensures whisper-quiet performance under idle conditions. In contrast, the Thermalright Assassin X 90 SE V2 has a maximum noise level of 23.85 dB(A), which is still reasonable for a cooling fan but may not match the near-silent operation of the Noctua product. For users prioritising silence, the Noctua cooler may be the preferable choice.

Which should you buy?

Choosing between the Noctua NH-L9i-17xx and the Thermalright Assassin X 90 SE V2 ultimately depends on your specific needs and budget. If you are looking for a high-quality, compact cooler with a strong emphasis on silent operation and brand reputation, the Noctua NH-L9i-17xx is worth the investment at C$59.95. However, if you are on a tighter budget and still require effective cooling with solid performance, the Thermalright Assassin X 90 SE V2 at C$24.90 offers remarkable value. Consider your priorities around cooling performance, noise levels, and budget to make the best choice for your system.
