Overview of the Products

When comparing the Thermalright Assassin X 120R SE V2 CPU Air Cooler and the Thermalright TL-S12RW X3 CPU Fan, both products showcase Thermalright's commitment to efficient cooling solutions, but they serve different purposes. The Assassin X 120R SE V2 is a comprehensive CPU air cooler priced at C$23.59, while the TL-S12RW X3, which costs C$19.90, is designed primarily as a case fan that can also complement CPU coolers.

The Assassin X 120R SE V2 integrates advanced cooling technologies and is suitable for a variety of CPU sockets, making it versatile for different builds. In contrast, the TL-S12RW X3 stands out with its unique design and features that enhance airflow and reduce noise, appealing to users looking for sleek aesthetics and quiet operation.

Cooling Performance

The Thermalright Assassin X 120R SE V2 excels in cooling performance with its four 6mm heat pipes and an airflow rating of 66.17 CFM at a maximum fan speed of 1550 RPM. This high airflow is crucial for dissipating heat from high-performance CPUs, ensuring stable operation during intensive tasks. The noise level is kept relatively low at 25.6 dB(A), making it a solid choice for users prioritizing performance alongside quiet operation.

On the other hand, the TL-S12RW X3 operates at a maximum speed of 1500 RPM and delivers an airflow of 47.6 CFM, which is good for case ventilation and can help maintain overall system temperatures. While it may not match the cooling capacity of the Assassin X 120R SE V2, its design allows for effective cooling in both cases and as a supplemental fan for CPU coolers.

Design and Aesthetics

The design of the Thermalright Assassin X 120R SE V2 is functional, with a height of 148mm that fits into most medium-sized cases without obstructing RAM slots. Its industrial-strength PBT + PC material ensures durability. The self-luminous fan adds a unique touch, providing illumination that can enhance the aesthetic appeal of a gaming setup.

In comparison, the TL-S12RW X3 features a pure white design with slim round ARGB lines, creating a modern and visually appealing look. The soft silicone feet help minimise vibrations and noise, further contributing to a quiet computing environment. Both products reflect Thermalright's attention to aesthetics and performance, but the TL-S12RW X3 may appeal more to users who value visual design alongside functionality.

Noise Levels

In terms of noise levels, the Thermalright Assassin X 120R SE V2 operates at a maximum of 25.6 dB(A), which is relatively quiet for a CPU cooler of its capabilities. This low noise level makes it an excellent choice for users who require a silent operation during gaming or work sessions.

Conversely, the TL-S12RW X3 is slightly quieter, with a maximum noise level of 23.2 dB(A). This reduction in sound makes it an ideal choice for those who prioritise a silent environment, especially in builds where multiple fans are used. Although both fans are designed to operate quietly, the TL-S12RW X3 edges out slightly in this category.

Compatibility

The Thermalright Assassin X 120R SE V2 offers extensive compatibility with various CPU socket types, including Intel's LGA1150 through LGA1700 and AMD's AM4 and AM5 platforms. This versatility allows users to integrate the cooler into a wide range of systems without worrying about compatibility issues, making it a practical choice for both new builds and upgrades.

In contrast, while the TL-S12RW X3 is primarily a case fan, it can also be effectively used in conjunction with CPU coolers to enhance cooling performance. However, it does not have the same level of direct compatibility with CPU sockets, as its primary role is to assist with airflow within the chassis.

Durability and Lifespan

The Thermalright Assassin X 120R SE V2 boasts an impressive lifespan of up to 20,000 hours, thanks to its S-FDB bearings, which are designed to provide long-lasting performance under continuous use. This durability makes it a reliable choice for users who demand consistent cooling over extended periods.

The TL-S12RW X3 also features S-FDB V2 bearings, ensuring a long operational lifespan while reducing vibration and noise. However, specific longevity figures are not provided, making it slightly less transparent in terms of lifespan compared to the Assassin X 120R SE V2. Both products are built to last, but the explicit longevity claim of the Assassin X 120R SE V2 gives it an edge in this category.

Price Comparison

Price is a crucial factor when choosing between these two products. The Thermalright Assassin X 120R SE V2 is priced at C$23.59, while the Thermalright TL-S12RW X3 is more budget-friendly at C$19.90. The price difference of C$3.69 reflects the additional features and capabilities of the Assassin X 120R SE V2, which serves as a dedicated CPU cooler, whereas the TL-S12RW X3 functions primarily as a case fan.

While both products offer good value for their respective functionalities, the choice ultimately depends on whether a user prioritises a dedicated CPU cooler or a versatile case fan that can support cooling needs.

Which should you buy?

In conclusion, the choice between the Thermalright Assassin X 120R SE V2 CPU Air Cooler and the Thermalright TL-S12RW X3 CPU Fan ultimately rests on your specific cooling needs. If you require robust CPU cooling performance with extensive compatibility and durability, the Assassin X 120R SE V2 is the superior option, albeit at a slightly higher price. However, if you are looking for an aesthetically pleasing, quiet case fan that can enhance airflow and support your CPU cooler, the TL-S12RW X3 offers excellent value with its lower price point. Consider your system's requirements and personal preferences when making your decision.
