Dimension comparison
Brand Overview
Both the Thermalright Assassin X 90 SE V2 CPU Cooler and the Thermalright Burst Assassin 120 SE ARGB CPU Air Cooler come from Thermalright, a Taiwanese brand with over 20 years of experience in the CPU cooling market. This brand has established itself as a key player in the industry, known for its innovation in computer accessories, including CPU air coolers and case fans. Each product reflects the brand’s commitment to quality and performance, though they cater to slightly different needs and preferences within the market.
Design and Build Quality
The design of the Thermalright Assassin X 90 SE V2 CPU Cooler is compact, with dimensions of 94mm x 77mm x 118mm. This cooler features a heat sink made from aluminum, combining high density with direct-touch technology for optimal thermal transfer. In contrast, the Burst Assassin 120 SE ARGB stands taller and broader, relying on an impressive six nickel-plated heat pipes for enhanced heat dissipation. Its larger fan, measuring 120mm, further boosts airflow and cooling efficiency. Both coolers utilise durable materials, but the Burst model's design is aimed at providing better thermal management due to its larger size and enhanced airflow capabilities.
Cooling Performance
When it comes to cooling performance, the Thermalright Burst Assassin 120 SE ARGB outshines its competitor, boasting a maximum airflow of 66.17 CFM compared to the Assassin X 90 SE V2's 32.77 CFM. This significant difference means that the Burst model can dissipate heat more efficiently, making it ideal for high-performance CPUs that generate more heat under load. Additionally, the Burst model's fan operates at a lower maximum noise level of 25.6dB(A), while the Assassin X 90 SE V2 reaches up to 23.85dB(A) at its peak. Despite the difference in noise levels, the Burst model's superior airflow makes it the better choice for those prioritizing cooling efficiency.
Fan Technology
Both coolers employ advanced fan technology, but they differ in size and speed. The Thermalright Assassin X 90 SE V2 features a 92mm fan that operates at speeds of up to 2200 RPM. While this high speed can deliver effective cooling, the smaller fan size limits airflow compared to the Burst Assassin 120 SE ARGB's 120mm fan, which runs at a maximum of 1550 RPM. The Burst model's fan is designed to provide a balanced performance, combining sufficient airflow with lower noise output. This makes the Burst model more suitable for users seeking a quieter computing environment without sacrificing cooling performance.
Compatibility
In terms of compatibility, both coolers support a wide range of CPU socket types. The Thermalright Assassin X 90 SE V2 is compatible with Intel's 1150, 1151, 1155, 1156, and 1200 sockets, as well as AMD's AM4 and AM5 sockets. The Burst Assassin 120 SE ARGB goes a step further, supporting additional Intel sockets like 1700 and 1851. This broader compatibility makes the Burst model a more versatile option for users with newer motherboard models. Furthermore, both products come with mounting accessories to facilitate installation, though the Burst model also incorporates features designed to ease maintenance and upgrades.
Price Point
The Thermalright Assassin X 90 SE V2 is priced at C$24.90, while the Thermalright Burst Assassin 120 SE ARGB is slightly higher at C$29.90. The modest price difference reflects the enhanced features and performance of the Burst model. For an additional C$5.00, users gain access to superior cooling capabilities, larger fan size, and better overall performance. While the Assassin X 90 SE V2 is an attractive option for budget-conscious consumers, the Burst model offers greater value for those willing to invest a little more for improved efficiency.
Aesthetic Appeal
The aesthetic appeal of the Thermalright Burst Assassin 120 SE ARGB is particularly noteworthy due to its addressable RGB lighting, which allows for customisation and enhances the overall look of a gaming setup. This feature is absent in the more utilitarian design of the Assassin X 90 SE V2, which does not include RGB options. For users who value visual elements in their builds, the Burst model is clearly the more attractive choice. The ability to synchronise lighting with other components adds a layer of personalisation that many modern gamers and PC builders appreciate.
Which should you buy?
Choosing between the Thermalright Assassin X 90 SE V2 CPU Cooler and the Thermalright Burst Assassin 120 SE ARGB CPU Air Cooler ultimately depends on your specific needs and preferences. If you are looking for a budget-friendly option that provides solid performance in a compact design, the Assassin X 90 SE V2 is a great choice. However, for those seeking superior cooling performance, enhanced compatibility, and aesthetic appeal, the Burst Assassin 120 SE ARGB stands out as the superior option. The additional investment in the Burst model is justified by its advanced features and better overall performance, making it the recommended choice for most users.
