Price Comparison

When it comes to pricing, the Thermalright Assassin X 120R Digital ARGB Black CPU Cooler is significantly more expensive than the Thermalright TL-S12RW X3 CPU Fan. The Assassin X is priced at C$32.90, while the TL-S12RW X3 is more budget-friendly at C$19.90. This difference of C$13.00 can be attributed to the additional features and cooling capabilities offered by the Assassin X. Therefore, if budget is a significant factor in your decision-making, the TL-S12RW X3 provides a more economical choice without entirely sacrificing performance.

Cooling Performance

In terms of cooling performance, the Thermalright Assassin X 120R stands out with its more powerful specifications. The Assassin X features a fan speed of 2000 RPM, generating an air volume of 70.84 CFM, compared to the TL-S12RW X3, which operates at a lower speed of 1500 RPM and a reduced air flow of 47.6 CFM. This means that the Assassin X can dissipate heat more effectively, making it more suitable for high-performance CPUs or overclocking scenarios. While the TL-S12RW X3 does provide adequate cooling for standard applications, it may not match the intense cooling demands of more powerful systems.

Noise Levels

The noise levels produced by both products are relatively low, but the TL-S12RW X3 has an edge in terms of quiet operation. The Assassin X operates at a noise level of ≤ 29.8 dBA, while the TL-S12RW X3 is quieter at ≤ 23.2 dBA. This makes the TL-S12RW X3 an appealing option for users who prioritise a silent computing environment. On the other hand, the slightly higher noise level of the Assassin X is a trade-off for its superior cooling performance, making it a better option for those who need efficient cooling over absolute silence.

Design and Aesthetics

The Thermalright Assassin X 120R offers a more robust design with its digital ARGB lighting, which can synchronise with your motherboard for a vibrant visual experience. Its all-aluminium fins not only enhance heat dissipation but also contribute to its aesthetic appeal. The TL-S12RW X3, while also featuring ARGB elements, has a simpler design with a pure white finish and slim ARGB lines. The unique shape and soft silicone feet help reduce noise, enhancing its functional design. Ultimately, if aesthetics and custom lighting are important to you, the Assassin X might be the more visually striking option.

Compatibility

Both the Thermalright Assassin X 120R and TL-S12RW X3 boast wide compatibility, but the Assassin X offers more versatility with support for dual platforms, including Intel LGA 1851/1700/1150/1151/1155/1156/1200 and AMD AM4/AM5 sockets. This broad compatibility ensures that you can use it across a variety of systems. The TL-S12RW X3 is also compatible with most cases and can be used as a case fan or in conjunction with CPU coolers, but it lacks the extensive socket support of the Assassin X. Therefore, if you're building or upgrading a system with specific socket requirements, the Assassin X provides a more comprehensive solution.

Bearing Technology

The Thermalright TL-S12RW X3 employs S-FDB V2 bearing technology, which enhances the fan's longevity and reduces vibration. This is particularly useful in maintaining a quieter operation over time. On the other hand, the Assassin X does not specify its bearing type, which makes it difficult to compare their long-term reliability directly. However, the TL-S12RW X3’s advanced bearing system suggests a focus on durability and noise reduction, making it a suitable choice for users concerned about the lifespan of their cooling components.

Installation Ease

Installation can be a crucial factor for many users, and both the Thermalright Assassin X 120R and TL-S12RW X3 come with installation accessories. The Assassin X is equipped with a detailed installation manual and video guidance, making it straightforward for users to set up. The TL-S12RW X3, being a simpler case fan, is likely to be even easier to install, given its basic design and standard 4-pin PWM connector. For users looking for an uncomplicated installation process, the TL-S12RW X3 stands out as the more user-friendly option.

Which should you buy?

Deciding between the Thermalright Assassin X 120R Digital ARGB Black CPU Cooler and the Thermalright TL-S12RW X3 CPU Fan largely depends on your specific needs. If you're looking for powerful cooling performance, extensive compatibility, and advanced aesthetics, the Assassin X is the clear winner at C$32.90. However, if you prioritise budget, quieter operation, and ease of installation, the TL-S12RW X3 at C$19.90 offers excellent value. Ultimately, assess your cooling requirements and budget to make the best choice for your setup.
