Overview of the Thermalright Assassin X 90 SE V2 CPU Cooler

The Thermalright Assassin X 90 SE V2 CPU Cooler is a compact cooling solution that stands out for its impressive design and features. With dimensions of 94mm in length, 77mm in width, and 118mm in height, it is designed to fit in a variety of chassis models. This cooler is priced at C$24.90, making it an affordable option for those seeking effective CPU cooling. The use of four 6mm heat pipes and the AGHP technique enhances its cooling efficiency, enabling the cooler to handle a significant thermal load, which is essential for maintaining optimal CPU performance.

The Assassin X 90 SE V2 is equipped with a PWM fan that operates at a maximum speed of 2200 RPM, offering an airflow of 32.77 CFM while maintaining a noise level of just 23.85 dB(A). This blend of performance and low noise makes it an appealing choice for users who prioritize a quiet computing environment. Additionally, its compatibility with both Intel and AMD sockets, including Intel's LGA 1200 and AMD's AM5, ensures that it can cater to a wide range of build configurations.

Overview of the Thermalright Assassin Spirit 120 EVO Dark CPU Cooler

The Thermalright Assassin Spirit 120 EVO Dark CPU Cooler is another excellent offering from Thermalright, featuring a slightly larger design compared to its counterpart. Measuring 120mm in length, 73mm in width, and 156mm in height, it provides ample cooling capabilities. Also priced at C$24.90, it presents a comparable value to the Assassin X 90 SE V2. This cooler utilises four 6mm heat pipes and an anodic black brushed top cover that enhances its aesthetic appeal while also maximising heat dissipation.

The Spirit 120 EVO Dark boasts a PWM fan with a rotation speed of 1850 RPM, providing efficient cooling performance while ensuring that noise levels are kept in check. Its design allows for a universal fit across various Intel and AMD sockets, including the latest LGA 1700 and AM5. With its effective cooling design and user-friendly installation process, this cooler is well-suited for both novice builders and seasoned enthusiasts alike.

Cooling Performance Comparison

When it comes to cooling performance, both the Assassin X 90 SE V2 and the Spirit 120 EVO Dark offer impressive specifications. The Assassin X 90 SE V2 features a maximum airflow of 32.77 CFM, supported by a fan that reaches speeds of 2200 RPM. Its compact design allows for efficient heat dissipation, particularly in smaller chassis where space is a premium.

In contrast, the Spirit 120 EVO Dark, while slightly larger, has a lower maximum fan speed of 1850 RPM. However, it compensates for this with its larger size, which can enhance overall cooling efficiency. The larger heat sink and body of the Spirit 120 EVO Dark allow for increased heat dissipation area, potentially making it more effective in high-performance scenarios. Therefore, while the X 90 SE V2 may excel in RPM and airflow, the Spirit 120 EVO Dark's design could lead to superior thermal management in more demanding applications.

Noise Level Assessment

Noise level is a critical consideration for many users, especially those building a quiet PC. The Assassin X 90 SE V2 operates at a maximum noise level of just 23.85 dB(A), making it one of the quieter options available. This low noise output is particularly notable given its higher fan speed, indicating effective engineering that prioritises silent operation without sacrificing performance.

On the other hand, the Spirit 120 EVO Dark also maintains reasonable noise levels, although specific dB ratings are not provided. The combination of its PWM fan control and lower RPM helps keep noise to a minimum. While both coolers aim to operate quietly, the Assassin X 90 SE V2 has a quantifiable edge in this category, making it a better choice for users sensitive to noise.

Installation and Compatibility

Both coolers offer straightforward installation processes with wide compatibility across various CPU platforms. The Assassin X 90 SE V2 supports Intel sockets 1150 through 1200 and AMD's AM4/AM5, ensuring it can accommodate a broad range of systems. Its compact dimensions also ease installation in tighter spaces.

The Spirit 120 EVO Dark shares similar compatibility, supporting Intel sockets from LGA 1150 to 1700 and AMD’s AM4/AM5. This universal compatibility makes both coolers suitable for a wide array of builds. However, the Spirit 120 EVO Dark requires the original backplate for AM4/AM5 installations, which may add a minor complication for some users. Overall, both units are designed for ease of use, but the Assassin X 90 SE V2 may be slightly more user-friendly in tighter configurations.

Aesthetic Appeal

Aesthetically, the Spirit 120 EVO Dark has a distinct advantage due to its anodic black brushed top cover, which gives it a modern and stylish look. This could be particularly appealing for users looking to build a visually striking rig. The sleek finish and design elements create a premium feel, setting it apart in a competitive market.

Conversely, the Assassin X 90 SE V2 features a more utilitarian design, focusing primarily on performance rather than visual flair. While it may not have the same aesthetic appeal as the Spirit 120 EVO Dark, its straightforward design is functional and effective. For users prioritising performance over looks, the X 90 SE V2 remains an excellent choice.

Which should you buy?

Deciding between the Thermalright Assassin X 90 SE V2 and the Thermalright Assassin Spirit 120 EVO Dark ultimately depends on your specific needs. If you prioritise a quieter operation and a compact design, the Assassin X 90 SE V2 stands out with its lower noise levels and efficient cooling capabilities. However, if you prefer a stylish cooler with potentially enhanced thermal performance due to its larger size, the Spirit 120 EVO Dark is an excellent option.

Both coolers are competitively priced at C$24.90 and offer solid performance, making them suitable for a variety of builds. Consider your priorities—whether it be aesthetics, noise levels, or cooling efficiency—to make the best choice for your PC cooling needs.
