Dimension comparison
Overview of the Thermalright Assassin X 120R SE V2 and AXP-120-X67
The Thermalright Assassin X 120R SE V2 is priced at $16.59, making it a budget-friendly option. In contrast, the Thermalright AXP-120-X67 is considerably more expensive at $32.59, which is about 96% higher than its rival. This price difference may influence buyers who are looking for affordability without compromising on performance.
The Assassin X 120R SE V2 features four 6mm heat pipes and a 120mm RGB PWM fan, offering effective cooling performance. Meanwhile, the AXP-120-X67 features six heat pipes and a low-profile design, catering to users with space constraints. Both coolers are compatible with a range of Intel and AMD sockets, making them versatile choices for various builds.
Cooling Performance
When it comes to cooling performance, the Thermalright AXP-120-X67 is designed for efficiency with its six heat pipes and a PWM fan that operates at 1800 RPM. This configuration allows it to deliver a maximum airflow of 59 CFM while maintaining a noise level of up to 26.1 dB(A). On the other hand, the Assassin X 120R SE V2 utilizes four heat pipes and a fan speed of 1550 RPM, achieving an airflow of 66.17 CFM but with a slightly quieter operation at 25.6 dB(A).
While the AXP-120-X67's higher RPM can provide better cooling performance under load, the Assassin X 120R SE V2 offers a balance between airflow and noise, making it a compelling choice for quieter systems. The choice between these two will ultimately depend on the user's specific cooling needs and noise tolerance.
Design and Aesthetics
In terms of design, the Assassin X 120R SE V2 stands out with its RGB lighting, which can add a vibrant touch to any build. Its dimensions are 120mm x 71mm x 148mm, making it a suitable fit for medium-sized cases. Conversely, the AXP-120-X67 has a more understated appearance with its black ARGB design and low-profile height of just 67mm.
This low-profile design is particularly beneficial for compact builds where space is at a premium. Both coolers are constructed from high-quality materials, including aluminum and copper, ensuring durability and effective heat dissipation. Ultimately, the choice here will depend on whether the user prefers a more traditional RGB look or a sleek, understated aesthetic.
Installation and Compatibility
The installation process for both coolers is straightforward, as each comes with metal fasteners compatible with various Intel and AMD sockets. The Assassin X 120R SE V2 supports Intel sockets including LGA 1150, 1151, 1200, and AMD AM4/AM5, while the AXP-120-X67 supports similar Intel sockets along with LGA 2011 and 2066.
The AXP-120-X67’s lower profile makes it advantageous for builds with limited clearance above the CPU, while the Assassin X 120R SE V2's height of 148mm ensures it can fit into a wide range of cases without blocking RAM slots. For users with tighter builds, the AXP-120-X67 is likely the better choice, whereas the Assassin X 120R SE V2 suits those with more standard setups.
Noise Levels
Noise levels are an important consideration for many builders, especially for those seeking a quiet computing environment. The Assassin X 120R SE V2 operates at a maximum noise level of 25.6 dB(A), which is quieter than the AXP-120-X67's maximum of 26.1 dB(A). Though the difference in decibels is minimal, the Assassin X 120R SE V2 may provide a quieter experience in most scenarios.
However, the AXP-120-X67 compensates for its slightly higher noise output with potentially more aggressive cooling performance due to its higher fan speed. Users who prioritize silent operation might lean towards the Assassin X 120R SE V2, while those who need optimal cooling are likely to consider the AXP-120-X67.
Brand Reputation and Quality
Thermalright has built a solid reputation over more than 20 years in the market, focusing on the development of high-quality cooling solutions. Both products are designed with quality bearings and high-performance fans to ensure longevity and reliability. The AXP-120-X67, with its advanced AGHP technique, showcases the brand’s commitment to innovation, while the Assassin X 120R SE V2 emphasizes a balance of performance and affordability.
Both options benefit from Thermalright’s extensive experience and focus on user satisfaction, ensuring that buyers can trust either choice for their cooling needs. However, the features in each model cater to slightly different user priorities, which is worth considering when making a purchase.
Which should you buy?
Deciding between the Thermalright Assassin X 120R SE V2 and the AXP-120-X67 ultimately depends on your specific needs and budget. The Assassin X 120R SE V2, at $16.59, offers excellent value with its effective cooling, RGB aesthetics, and quieter operation. It is ideal for users looking for a cost-effective solution without sacrificing performance.
In contrast, the AXP-120-X67, priced at $32.59, provides superior cooling potential thanks to its six heat pipes and higher RPM fan, making it well-suited for more demanding setups or compact builds where space is limited. If budget is not a primary concern and performance is paramount, the AXP-120-X67 would be the better choice.
Ultimately, both coolers have their strengths, and your decision should reflect your unique requirements in terms of cooling performance, noise levels, and budget.
