Overview of the Products
When comparing the Thermalright Assassin X 120R Digital ARGB Black CPU Air Cooler and the Thermalright Assassin X 120R SE V2 CPU Cooler, it is evident that both products cater to users seeking efficient CPU cooling solutions. The Digital ARGB model is priced at $22.90, while the SE V2 is more budget-friendly at $16.59, making it approximately 17% cheaper. Both coolers are designed for excellent performance, but they differ in features and specifications that may influence your decision.
Design and Aesthetics
The Thermalright Assassin X 120R Digital ARGB Black CPU Air Cooler boasts a stunning design with a digital screen top cover and customizable ARGB lighting. This cooler's aesthetic appeal is enhanced by its 151mm height and sleek appearance, making it compatible with most cases while maintaining a stylish look. In contrast, the Assassin X 120R SE V2 features a simpler design but remains functional with its 148mm height. Although it lacks the advanced ARGB lighting of its competitor, it still offers an attractive appearance suitable for many PC builds. The choice between these two designs will largely depend on your personal preference for aesthetics versus simplicity.
Cooling Performance
Cooling performance is crucial for any CPU cooler, and both models deliver impressive results. The Thermalright Assassin X 120R Digital ARGB features a fan speed of 2000 RPM, which can effectively manage heat dissipation in high-performance scenarios. The SE V2, while slightly slower at 1550 RPM, also provides efficient cooling with a maximum airflow of 66.17 CFM. The difference in fan speed translates to a potential for better cooling in the Digital ARGB model, making it a preferable option for users engaged in intensive computing tasks. However, the SE V2 still holds its ground as a reliable cooler for moderate usage.
Noise Levels
Noise levels are an essential consideration for any CPU cooler, particularly for users seeking a quiet computing environment. The Thermalright Assassin X 120R SE V2 operates at a maximum noise level of 25.6 dB(A), which is relatively quiet and ideal for silent builds. On the other hand, while the Digital ARGB model does not specify its maximum noise level, it employs silicone corner pads to minimize noise during operation. Users may find that both coolers maintain relatively quiet performance, but the SE V2's defined noise level may be more reassuring for those prioritizing quietness.
Compatibility
Both the Thermalright Assassin X 120R Digital ARGB and the SE V2 are compatible with a range of CPU sockets, including Intel LGA1700, 1150, 1151, 1200, and AMD AM4/AM5 platforms. The SE V2 provides a slightly more straightforward installation process with its included fasteners for both Intel and AMD platforms, ensuring a hassle-free setup. The Digital ARGB model also supports these sockets but is designed with a digital screen that requires additional software installation for full functionality. Ultimately, both coolers offer broad compatibility, but the SE V2 may appeal to users seeking simplicity.
Fan Technology
Fan technology plays a significant role in the performance of CPU coolers. The Thermalright Assassin X 120R Digital ARGB utilizes a PWM fan that can automatically adjust its speed based on motherboard temperature, providing a balance between performance and noise. Its S-FDB bearing technology helps prevent blade shaking, ensuring longevity and reliability. Similarly, the Assassin X 120R SE V2 employs quality S-FDB bearings, which offer similar benefits in terms of noise reduction and performance. Users can feel confident in the durability and efficiency of both coolers, although the Digital ARGB model may have the edge with its higher RPM capability.
Installation and Maintenance
Installation and maintenance are vital aspects for users who may not be as experienced with PC building. The Thermalright Assassin X 120R SE V2 has a height of 148mm, making it a suitable choice for medium-sized cases without obstructing memory installation. Its straightforward mounting system simplifies the installation process. The Digital ARGB model, while slightly taller at 151mm, also maintains good compatibility but may require additional steps for the digital screen setup. Both coolers are relatively easy to install, but the SE V2’s design could be more appealing for novice builders looking for an efficient yet uncomplicated setup.
Price Comparison
Price is always a crucial factor in product evaluation. The Thermalright Assassin X 120R Digital ARGB is priced at $22.90, while the Assassin X 120R SE V2 comes in at a more budget-friendly $16.59. This price difference of about 17% may be significant for users on a tight budget. While the Digital ARGB model offers additional features such as improved aesthetics and a higher fan speed, the SE V2 provides solid performance at a lower cost, making it an attractive option for those who prioritize value.
Which should you buy?
Choosing between the Thermalright Assassin X 120R Digital ARGB Black CPU Air Cooler and the Thermalright Assassin X 120R SE V2 CPU Cooler ultimately depends on your specific needs and preferences. If you value aesthetics, higher performance, and the latest features like digital screens and ARGB lighting, the Digital ARGB model is the way to go. However, if you're looking for a reliable, quieter, and more budget-friendly option, the SE V2 is an excellent choice. Both coolers provide solid performance, but your decision should be based on whether you prioritize style or savings.
