The Thermalright Assassin X 120R SE Plus CPU Cooler is designed for both performance and noise reduction, featuring advanced cooling technology. Priced at C$25.59, this cooler employs four 6mm heat pipes and double PWM fans to provide effective cooling while maintaining a noise level of just 25.6 dB(A). Thermalright, a well-established brand with over 20 years of experience, focuses on quality and performance in its product offerings, making this cooler a reliable choice for gaming and high-performance PCs.
The Assassin X 120R SE Plus features a fan speed of 1550 RPM, allowing for an airflow of 66.17 CFM. It is compatible with a wide range of CPU socket types, including Intel's 1700 and AMD's AM5, thus providing versatility in installation. The product's AGHP technique aids in countering the inverse gravity effect, enhancing its cooling capability across various orientations, making it suitable for multiple setups.
Overview of the Thermalright AXP120-X67
The Thermalright AXP120-X67 Low Profile CPU Air Cooler offers a compact design without compromising on cooling efficiency. With a price tag of C$36.90, this cooler is slightly more expensive than the Assassin X 120R SE Plus, but it boasts unique features that may justify the cost for certain users. The AXP120-X67 is designed for low-profile builds, measuring just 67mm in height, making it an ideal choice for compact cases.
Equipped with 6×6mm heat pipes, this cooler ensures efficient thermal dissipation, and its PWM fan operates at a speed of 1800 RPM, generating an airflow of 59 CFM. Despite its lower airflow compared to the Assassin X, it maintains a noise level of 26.1 dB(A), slightly higher than its competitor. The AXP120-X67 has broad compatibility as well, supporting various Intel and AMD sockets, ensuring it fits a wide array of builds.
Cooling Performance Comparison
In terms of cooling performance, the Thermalright Assassin X 120R SE Plus stands out with its higher airflow of 66.17 CFM compared to the AXP120-X67's 59 CFM. This difference can be critical for users aiming for maximum cooling efficiency, especially in overclocked systems. Moreover, the Assassin X operates at a lower noise level of 25.6 dB(A), making it a quieter option during high-performance tasks.
Both coolers utilize the AGHP technique that mitigates the inverse gravity effect, ensuring optimal cooling regardless of orientation. However, the Assassin X's combination of higher airflow and lower noise levels positions it as a more effective choice for users who prioritize a balance between performance and quiet operation.
Noise Levels and User Experience
Noise levels play a significant role in the user experience of any cooling solution. The Assassin X 120R SE Plus operates at a maximum noise level of 25.6 dB(A), rendering it almost silent during operation. In contrast, the AXP120-X67's noise level reaches up to 26.1 dB(A), which is slightly louder but still considered quiet for a CPU cooler.
The difference of 0.5 dB(A) might seem minimal, yet for users who are sensitive to sound, this can be an important factor. The Assassin X's quieter operation makes it a better option for users who prioritize a peaceful computing environment, whether for gaming, work, or general use.
Installation and Compatibility
Both the Thermalright Assassin X 120R SE Plus and the AXP120-X67 are designed with user-friendly installation in mind, offering compatibility with a wide range of Intel and AMD sockets. The Assassin X supports Intel sockets from 1150 to 1700 and AMD AM4/AM5, while the AXP120-X67 also accommodates a similar range of Intel and AMD sockets, including 2011 and 2066.
The ease of installation is enhanced by the inclusion of necessary mounting plates and fasteners in both products. However, the AXP120-X67's low-profile design may appeal to users with space restrictions, as it can fit into tighter cases where traditional coolers may not.
Brand Reputation and Reliability
Both products stem from Thermalright, a reputable brand with over two decades of experience in the cooling market. This brand's longstanding presence indicates a commitment to quality and reliability. The materials used in both coolers are designed to ensure durability, with the Assassin X featuring S-FDB bearings that extend fan life and minimise noise. Similarly, the AXP120-X67 uses pure copper heat pipes and aluminum fins, which contribute to effective heat dissipation.
Given the brand's history and the positive reception of its products, users can expect a level of reliability and performance that is well-supported by Thermalright's research and development efforts.
Pricing Considerations
Price is always a crucial factor when making a purchasing decision. The Thermalright Assassin X 120R SE Plus is priced at C$25.59, making it a more budget-friendly option for those looking for effective cooling without breaking the bank. On the other hand, the AXP120-X67 is priced at C$36.90, which may be justified by its low-profile design and slightly more advanced features.
Ultimately, the choice between the two may depend on the user's specific needs and budget. For those seeking maximum performance at a lower price, the Assassin X is compelling. However, users with space constraints may find the AXP120-X67 worth the extra investment.
Which should you buy?
The decision between the Thermalright Assassin X 120R SE Plus and the AXP120-X67 hinges on your specific requirements.
