Overview of Thermalright TL-S12W X3 CPU Fan

The Thermalright TL-S12W X3 CPU Fan is an efficient cooling solution designed for case and CPU cooling. Priced at C$19.59, this product offers high performance with a maximum speed of 1500 RPM and a noise level of just 23.2 dBA. The fan's automatic speed control through a 4-pin PWM fan cable interface ensures optimal cooling based on motherboard temperature, making it a versatile choice for various setups.

Thermalright, a well-established brand with over 20 years of experience, focuses on the research and development of computer accessories. The TL-S12W X3 features soft silicone feet for reduced noise and enhanced airflow, delivering 47.6 CFM. Each package includes three fans, making it a comprehensive solution for users looking to improve their system's cooling performance.

Overview of Thermalright Assassin King 120 SE ARGB CPU Air Cooler

The Thermalright Assassin King 120 SE ARGB CPU Air Cooler is a more advanced cooling solution, priced at C$24.59. This cooler stands out with its ARGB lighting effects and a fan speed of up to 1550 RPM, generating an impressive airflow of 66.17 CFM. With a noise level of 25.6 dBA, it provides efficient cooling while maintaining a relatively quiet operation.

Designed for compatibility with both Intel and AMD platforms, the Assassin King 120 SE features a well-constructed heat sink made from aluminum and includes metal fasteners for easy installation. The cooler’s advanced AGHP technique and five 6mm heat pipes enhance its cooling efficiency, making it suitable for CPUs with a thermal design power (TDP) of 125 to 235W.

Performance Comparison

When it comes to performance, the Thermalright TL-S12W X3 offers a maximum airflow of 47.6 CFM at a noise level of 23.2 dBA, while the Assassin King 120 SE pushes the limits further with a maximum airflow of 66.17 CFM but at a slightly higher noise level of 25.6 dBA. This indicates that while both fans are efficient, the Assassin King provides a greater cooling capability, ideal for more demanding setups.

The TL-S12W X3’s automatic speed control allows it to adjust its performance based on temperature readings, which can lead to quieter operation under lower loads. In contrast, the Assassin King’s ARGB features and slightly higher RPM may appeal to users looking for both aesthetics and performance, especially in gaming or high-performance scenarios.

Installation and Compatibility

The Thermalright TL-S12W X3 is designed with versatility in mind, suitable for case cooling and as a supplementary fan for CPU coolers. It comes with all necessary mounting screws and an instruction manual, making installation straightforward for users. Its compatibility with various cooling setups enhances its appeal.

On the other hand, the Assassin King 120 SE specifically targets CPU cooling, supporting multiple socket types for both Intel and AMD CPUs. Its dimensions of 120mm x 73mm x 148mm make it suitable for medium-sized cases. The inclusion of metal fasteners ensures a secure fit, which can be crucial for high-performance applications where stability is key.

Noise Levels and Acoustic Performance

In terms of acoustic performance, the Thermalright TL-S12W X3 operates at a maximum noise level of 23.2 dBA, making it one of the quieter options available for cooling fans. This low noise output can significantly enhance the user experience, especially in environments where silence is preferred, like home offices or media centers.

Conversely, the Assassin King 120 SE, while still relatively quiet at 25.6 dBA, produces slightly more noise due to its higher airflow and RPM. However, this trade-off can be justified by its superior cooling performance. Users prioritizing silence may lean towards the TL-S12W X3, while those who value cooling efficiency and aesthetics might prefer the Assassin King.

Aesthetic Appeal

The design features of the Thermalright TL-S12W X3 are functional but minimalistic, focusing on performance without additional flair. In contrast, the Assassin King 120 SE incorporates ARGB lighting, which not only enhances its visual appeal but also allows users to customize the lighting effects to match their build.

This aesthetic element can be a significant factor for gamers and PC enthusiasts who enjoy showcasing their setups. The ability to sync ARGB with other components can create a cohesive and visually stunning system, making the Assassin King a more attractive choice for those who value style alongside functionality.

Build Quality and Durability

The build quality of the Thermalright TL-S12W X3 is commendable, featuring insulation-grade PBT+PC materials that ensure durability. Its soft silicone feet further reduce vibrations, contributing to a longer lifespan and quieter operation.

Meanwhile, the Assassin King 120 SE is designed with longevity in mind as well, featuring S-FDB bearings and a construction that promises up to 20,000 hours of service life. The use of high-quality materials ensures that this cooler can withstand the rigours of high-performance computing, making it a reliable choice for gamers and content creators alike.

Which should you buy?

Ultimately, the choice between the Thermalright TL-S12W X3 CPU Fan and the Thermalright Assassin King 120 SE ARGB CPU Air Cooler depends on your specific needs. If you are looking for an affordable, efficient, and quiet cooling solution, the TL-S12W X3 at C$19.59 is an excellent option. However, if you require enhanced cooling capabilities, ARGB aesthetics, and compatibility with higher TDP CPUs, the Assassin King at C$24.59 stands out as the superior choice. Both products are backed by Thermalright's reputation for quality, ensuring that whichever option you choose, you are investing in a reliable cooling solution.
