Overview of Thermalright TL-C12CW-S X3 and Thermalright Assassin King 120 SE
The Thermalright TL-C12CW-S X3 CPU Fan is a versatile 120mm case cooler priced at C$17.99, while the Thermalright Assassin King 120 SE ARGB CPU Air Cooler is a more robust solution for CPU cooling, available for C$24.59. Both products come from the reputable Thermalright brand, known for its commitment to quality and performance in computer cooling solutions.
The TL-C12CW-S X3 is designed primarily for case cooling, featuring a maximum speed of 1550 RPM and an airflow rate of 66.17 CFM. It excels in providing silent operation with noise levels capped at 25.6 dBA. In contrast, the Assassin King 120 SE is a dedicated CPU air cooler that incorporates advanced heat pipe technology and is engineered to handle CPU TDPs ranging from 125 to 235 watts, making it a suitable choice for more demanding systems.
Performance Comparison
In terms of performance, the Thermalright TL-C12CW-S X3 operates at a maximum speed of 1550 RPM and achieves an airflow of 66.17 CFM, effectively drawing heat away from the case and CPU. The fan's design includes quality S-FDB bearings that minimise noise while maximising cooling efficiency, thereby extending its lifespan.
On the other hand, the Assassin King 120 SE also operates at the same maximum RPM and airflow as the TL-C12CW-S X3, but it employs a five-heat pipe design that enhances thermal conductivity and cooling efficiency. This makes the Assassin King a superior option for high-performance CPUs, as it can handle higher thermal loads with minimal noise, maintaining the same 25.6 dBA noise level.
Design and Aesthetics
The design of the Thermalright TL-C12CW-S X3 is visually appealing, featuring high-brightness LED lighting effects with ARGB support. It provides up to 17 modes of lighting, allowing for customisation and synchronisation with the motherboard. This aesthetic flexibility makes it an attractive choice for users who value visual appeal in their builds.
Conversely, the Assassin King 120 SE retains a professional look while incorporating ARGB lighting into its design. The cooler is slightly bulkier, measuring 120x73x148mm, which makes it more suitable for medium-sized cases. Its aluminium heat sink and metal fasteners add a robust feel, ensuring durability while providing effective cooling performance.
Installation Ease
When it comes to ease of installation, the Thermalright TL-C12CW-S X3 is designed to be user-friendly. It features a standard 4-pin PWM connector, making it compatible with most motherboards and easy to integrate into existing systems as a case fan.
In comparison, the Assassin King 120 SE includes mounting hardware for both Intel and AMD platforms, ensuring compatibility across a wide range of CPU sockets, including the latest models. This versatility, combined with the effective ARGB lighting control, makes the installation process straightforward for both novice and experienced builders.
Compatibility and Use Case
The TL-C12CW-S X3 functions effectively as a case fan but can also be used alongside CPU coolers, helping to maintain optimal temperatures within the case. Its airflow capabilities make it suitable for various setups, providing flexibility in configurations.
On the other hand, the Assassin King 120 SE is specifically designed as a CPU cooler, supporting a TDP range of 125 to 235 watts. This makes it an ideal choice for gamers or professionals using high-performance CPUs. Its compatibility with both Intel and AMD sockets allows for broader application across different build types.
Noise Levels
Both the Thermalright TL-C12CW-S X3 and the Assassin King 120 SE are designed for silent operation, with noise levels that do not exceed 25.6 dBA. This makes them excellent choices for users looking to maintain a quiet computing environment.
However, the TL-C12CW-S X3’s design, focusing on case cooling, ensures that it operates quietly while managing heat effectively. The Assassin King 120 SE, with its more complex cooling assembly, is also designed to be quiet, offering the same noise level while sustaining higher performance levels under load.
Price Consideration
The Thermalright TL-C12CW-S X3 is priced at C$17.99, making it an affordable option for those looking for a reliable case fan. Its combination of performance, aesthetics, and features offers great value for users on a budget.
In comparison, the Assassin King 120 SE is priced at C$24.59. While it is more expensive, its advanced cooling capabilities and compatibility with high-performance CPUs justify the price difference. Users looking to invest in a more capable cooling solution may find the additional cost worthwhile.
Which should you buy?
Choosing between the Thermalright TL-C12CW-S X3 and the Thermalright Assassin King 120 SE ultimately depends on your specific cooling needs and system configuration. If you require a versatile case fan with appealing aesthetics and silent operation, the TL-C12CW-S X3 is an excellent choice at a lower price point. However, if you are building a high-performance system that requires robust cooling capabilities, the Assassin King 120 SE offers superior performance and compatibility with demanding CPUs, making it worth the extra investment.
