Dimension comparison
Price Comparison
When it comes to price, the Noctua NH-L12S is significantly more expensive than the Thermalright Burst Assassin 120 SE ARGB. The Noctua NH-L12S is priced at C$87.95, while the Thermalright model is a budget-friendly C$29.90. This represents a difference of C$58.05, making the Thermalright a more appealing option for those looking to save on their cooling solution without sacrificing quality.
Cooling Performance
Cooling performance is a crucial factor for any CPU cooler, and here, the Thermalright Burst Assassin 120 SE ARGB has notable advantages. The Thermalright features a single tower design with six nickel-plated anti-oxidation pure copper heat pipes, allowing for efficient heat dissipation. It boasts a maximum fan speed of 1550 RPM and an airflow of 66.17 CFM, which can handle moderate heat loads effectively. In comparison, the Noctua NH-L12S is marketed as a premium low-profile cooler, providing adequate cooling for CPUs with moderate heat loads but does not specify airflow or RPM numbers, leaving its performance less quantifiable.
Noise Levels
Noise levels play an important role in the overall user experience of a CPU cooler. The Thermalright Burst Assassin operates at a maximum noise level of 25.6 dB(A), which is relatively quiet for its performance level. The Noctua NH-L12S is designed for ultra-quiet operation, thanks to its optimized NF-A12x15 120mm fan with PWM support. However, specific noise level ratings are not provided for the Noctua model, making it challenging to compare directly. Users seeking a quieter solution might lean towards Noctua’s reputation for low-noise designs, but without exact figures, the advantage remains speculative.
Size and Compatibility
Size and compatibility are critical when selecting a CPU cooler, especially for compact builds. The Noctua NH-L12S is a low-profile cooler with a total height of only 70mm, making it a suitable choice for ITX and HTPC systems. This compact design is essential for users with space constraints. In contrast, the Thermalright Burst Assassin has a standard height, but its fin offset technology allows it to avoid interference with memory height, which can be a significant advantage in certain setups. Both coolers are compatible with a wide range of Intel and AMD sockets, making them versatile options for various CPU platforms.
Installation Process
The installation process can vary greatly between different CPU coolers, impacting user experience. The Noctua NH-L12S includes the SecuFirm2 mounting system, designed for easy installation across multiple Intel and AMD sockets. This thoughtful design can simplify the setup for users who may not be seasoned builders. On the other hand, the Thermalright Burst Assassin also emphasizes ease of installation with its SS2 grommets and compatibility with various CPU models, but it requires the original motherboard backplane for AMD installations. While both coolers aim for user-friendly installation, Noctua's dedicated mounting system may provide a slight edge in simplicity.
Aesthetic Appeal
When it comes to aesthetic appeal, the Thermalright Burst Assassin stands out with its ARGB lighting, adding a modern touch to any build. The integrated 5V 3PIN ARGB lighting allows users to customize their rig’s look easily, appealing to gamers and PC builders who value aesthetics alongside performance. The Noctua NH-L12S, while sleek and professional, does not feature any RGB lighting, which may deter users looking for a more vibrant setup. Therefore, for those prioritizing aesthetics, the Thermalright model may be the more attractive choice.
Brand Reputation and Quality
Brand reputation is an essential consideration in the cooling market. Noctua is widely recognized for its high-quality, reliable cooling solutions and has received numerous awards for its products, including the NH-L12S. Its focus on silent performance and longevity has built a loyal customer base. Thermalright, while respected, does not have the same level of widespread recognition, particularly in the premium segment. However, the Burst Assassin offers impressive cooling features at a budget price, positioning it as a solid entry-level option. Ultimately, users may prefer Noctua for their established reputation but may find Thermalright's offering compelling for budget builds.
Which should you buy?
Deciding between the Noctua NH-L12S and the Thermalright Burst Assassin 120 SE ARGB largely depends on your specific needs and budget. If you are looking for a compact, premium-quality cooler with a reputation for quiet operation and are willing to invest C$87.95, the Noctua NH-L12S is a solid choice. However, if you are seeking an affordable solution that offers great cooling performance, aesthetic appeal, and a price tag of only C$29.90, the Thermalright Burst Assassin is hard to beat. Ultimately, your decision should hinge on factors such as budget, space constraints, and personal preferences regarding aesthetics and brand loyalty.
