Dimension comparison
Overview of the Noctua NH-D9L and Thermalright Burst Assassin 120 SE ARGB
The Noctua NH-D9L is a premium cooler priced at C$69.95, while the Thermalright Burst Assassin 120 SE ARGB offers a budget-friendly option at C$29.90. This significant price difference sets the stage for a detailed comparison between these two CPU coolers.
Design and Build Quality
The Noctua NH-D9L features a compact dual-tower design that stands only 110mm tall, making it ideal for small form factor builds and HTPCs. This design ensures compatibility with RAM and PCIe slots, which is crucial for maintaining space efficiency in tight setups. In contrast, the Thermalright Burst Assassin 120 SE ARGB employs a single tower design complemented by six nickel-plated copper heat pipes. While it can accommodate taller RAM modules due to its fin offset technology, its overall height and bulk may be less suited for extremely compact builds.
Cooling Performance
Cooling performance is one of the critical aspects of any CPU cooler. The Noctua NH-D9L is equipped with a highly optimised NF-A9 92mm fan, which operates quietly and efficiently, thanks to its PWM support and Low-Noise Adaptor. This design ensures that it can maintain low temperatures while remaining nearly silent. On the other hand, the Thermalright Burst Assassin 120 SE ARGB features a TL-C12C-S fan that can reach speeds of up to 1550 RPM, generating a maximum airflow of 66.17 CFM while maintaining a noise level of 25.6 dB(A). While both coolers offer good performance, the Noctua NH-D9L's dual-tower configuration may provide superior heat dissipation under heavy loads.
Installation Process
The installation process is crucial for ensuring optimal performance. The Noctua NH-D9L includes a SecuFirm2 mounting system that simplifies installation on a variety of Intel and AMD sockets, including LGA1851, LGA1700, and AM4. This thoughtful design is complemented by high-end NT-H1 thermal paste, which is included in the package. Conversely, the Thermalright Burst Assassin 120 SE ARGB also promises ease of installation, featuring a versatile mounting system compatible with multiple Intel and AMD socket types. However, it does require the use of the original motherboard backplane for AMD installations, which could complicate the process for some users.
Noise Levels
Noise levels are a vital consideration for many PC builders, particularly those seeking a quiet environment. The Noctua NH-D9L is known for its ultra-quiet operation, aided by its advanced fan design and low-noise adaptor. Although specific noise levels are not provided, its reputation suggests minimal acoustic output. In comparison, the Thermalright Burst Assassin 120 SE ARGB has a maximum noise level of 25.6 dB(A), which is fairly quiet for a budget cooler but may not match the near-silent operation of the Noctua.
Aesthetic Appeal
When it comes to aesthetics, the Thermalright Burst Assassin 120 SE ARGB stands out with its RGB lighting, which can be a significant draw for users looking to enhance their build's visual appeal. The ARGB feature allows for custom lighting effects, which can be synchronised with other components. In contrast, the Noctua NH-D9L opts for a more utilitarian design, focusing on performance over flashiness. While the Noctua is well-regarded for its quality, it may not appeal to those who prioritise visual flair in their setups.
Compatibility
The Noctua NH-D9L is compatible with a wide range of Intel and AMD sockets, including the latest offerings like LGA1700 and AM5. This broad compatibility makes it a versatile choice for various builds. Similarly, the Thermalright Burst Assassin 120 SE ARGB supports major Intel and AMD sockets, ensuring it can fit into most modern systems. The fin offset technology further enhances its ability to work with taller RAM modules, making it a flexible option for users with different configurations.
Price Comparison
Price is a significant factor in any product comparison. The Noctua NH-D9L is priced at C$69.95, reflecting its premium positioning and build quality. In contrast, the Thermalright Burst Assassin 120 SE ARGB is available for just C$29.90, making it an attractive option for budget-conscious consumers. While the Noctua offers superior features and performance, the Thermalright provides excellent value for those who do not require the utmost in cooling efficiency.
Which should you buy?
Ultimately, the choice between the Noctua NH-D9L and the Thermalright Burst Assassin 120 SE ARGB comes down to individual needs and budget. If you prioritise performance, quiet operation, and build quality, the Noctua NH-D9L is the superior option, albeit at a higher price. However, if you are looking for a cost-effective solution that still delivers decent cooling performance and offers RGB aesthetics, the Thermalright Burst Assassin 120 SE ARGB is an excellent choice. Each cooler has its strengths, making either a viable option depending on your specific requirements.
