Thermalright Assassin X 120 SE ARGB CPU Air Cooler vs Noctua NH-D9L

Overview of the Thermalright Assassin X 120 SE ARGB CPU Air Cooler

The Thermalright Assassin X 120 SE ARGB CPU Air Cooler is a competitively priced option at C$24.29, making it an appealing choice for budget-conscious users. With a height of 148mm, the cooler is designed to fit comfortably in medium-sized computer cases, while its 4×6mm heat pipes support a Thermal Design Power (TDP) of 125 to 225W, providing ample cooling for a range of CPUs.

Thermalright has over 20 years of experience in developing computer cooling solutions, and the Assassin X 120 SE is a testament to their commitment to quality. It features a PWM fan with a maximum speed of 1550 RPM, generating a maximum airflow of 66.17 CFM while maintaining a noise level of just 25.6 dB(A). This balance of performance and quiet operation makes it suitable for various applications, from gaming to general computing.

Overview of the Noctua NH-D9L

The Noctua NH-D9L is a premium cooler priced at C$69.95, reflecting its high-end performance and quality. Standing at only 110mm tall, this compact dual-tower cooler is optimised for small form factor builds, such as HTPCs and ITX systems, without overhanging RAM or PCIe slots on most modern motherboards.

Noctua is renowned for its quality, and the NH-D9L is no exception. It comes with a highly optimised NF-A9 92mm fan that supports PWM and features a Low-Noise Adaptor for automatic speed control, ensuring ultra-quiet operation. Additionally, it includes high-end NT-H1 thermal paste and a SecuFirm2 mounting system for easy installation. With a 6-year warranty, the NH-D9L stands as a reliable choice for both Intel and AMD processors.

Cooling Performance Comparison

In terms of cooling performance, both the Thermalright Assassin X 120 SE and Noctua NH-D9L are designed to handle significant thermal loads. The Assassin X 120 SE supports a TDP between 125 to 225W, making it suitable for a wide range of CPUs, including high-performance models. The NH-D9L, while compact, is also designed for robust cooling with efficient airflow thanks to its dual-tower design.

The Assassin X 120 SE offers a higher maximum airflow of 66.17 CFM compared to the NH-D9L's performance metrics, which are not explicitly stated but are known to be effective for its size. Thus, the Thermalright cooler might have an edge in scenarios demanding more intensive cooling, particularly for larger CPUs. However, the NH-D9L’s design excels in smaller builds where space is a premium.

Noise Levels and Acoustic Performance

Noise levels are an essential factor for many users, particularly those looking for a quiet computing experience. The Thermalright Assassin X 120 SE operates at a maximum noise level of 25.6 dB(A), which is fairly quiet and suitable for a range of environments. Its fan speed of 1550 RPM contributes to this low noise output, making it a good option for gamers and professionals alike.

On the other hand, the Noctua NH-D9L is specifically designed for ultra-quiet operation, with its NF-A9 fan optimised to minimise noise while maintaining performance. While explicit noise levels for the NH-D9L aren’t provided, Noctua fans are generally known for their low noise output, making it a strong contender for users prioritising silence over maximal airflow.

Installation and Compatibility

Installation ease can greatly influence a user’s choice of cooler. The Thermalright Assassin X 120 SE includes metal fasteners compatible with both Intel and AMD platforms, making it versatile for various builds. Its height of 148mm also allows it to fit in medium-sized cases without issue.

Conversely, the Noctua NH-D9L features a SecuFirm2 mounting system that simplifies installation across a range of Intel and AMD sockets, including the latest LGA1700 and AM5 platforms. Its compact size is particularly beneficial for smaller cases, where installation can often be tricky. Users building in confined spaces may appreciate the NH-D9L’s thoughtful design that avoids interference with RAM and PCIe slots.

Build Quality and Warranty

Build quality is critical in CPU coolers, and both brands offer reliable products. The Thermalright Assassin X 120 SE is crafted with industrial-strength materials, including PBT + PC material, ensuring durability. It is also backed by a respectable reputation from Thermalright, which has been in the industry for over 20 years.

The Noctua NH-D9L, however, is often regarded as a benchmark in cooler quality. With a 6-year manufacturer’s warranty, it reflects Noctua’s confidence in its product longevity and performance. Users may find this extended warranty appealing, especially for high-value components in their systems.

Which should you buy?

Choosing between the Thermalright Assassin X 120 SE ARGB CPU Air Cooler and the Noctua NH-D9L ultimately depends on your specific needs and budget. If you are looking for a budget-friendly cooler that provides robust performance and can handle higher TDP CPUs, the Thermalright Assassin X 120 SE is an excellent choice at C$24.29. Conversely, if you prioritise quiet operation, compact design, and high build quality, the Noctua NH-D9L, despite its higher price of C$69.95, may be the better option for you. Both coolers offer solid performance, but the right choice will hinge on your individual requirements and preferences.
