Dimension comparison
Brand Overview
Both the Thermalright TL-S12W X3 CPU Fan and the Thermalright Assassin X 120 SE ARGB CPU Air Cooler come from Thermalright, a brand with over 20 years of experience in the computer accessory market. This established brand is well-regarded for its innovative designs and quality products, appealing to both casual users and enthusiasts. While both products share the same brand lineage, their focuses differ significantly—one is a case fan, and the other is a comprehensive CPU cooler.
Cooling Performance
When comparing cooling performance, the Thermalright TL-S12W X3 offers a maximum speed of 1500 RPM, generating an airflow of 47.6 CFM with a noise level of 23.2 dBA. This makes it suitable for maintaining optimal temperatures within a case. In contrast, the Thermalright Assassin X 120 SE ARGB boasts a higher fan speed of 1550 RPM and an impressive airflow of 66.17 CFM, albeit with a slightly higher noise level of 25.6 dBA. These specifications suggest that the Assassin X 120 SE is better equipped to handle higher thermal loads, making it ideal for more demanding CPU cooling situations.
Design and Build Quality
In terms of design, the Thermalright TL-S12W X3 is a straightforward 120mm case fan that emphasizes noise reduction through its PBT+PC material and silicone dampening feet, which help minimize vibrations. The Thermalright Assassin X 120 SE, on the other hand, features a more complex design with a heat sink made of aluminum and four 6mm heat pipes that utilize AGHP technology. This not only enhances its cooling capabilities but also provides a more robust build quality. Its dimensions of 125mm x 71mm x 148mm allow it to fit in a medium-sized computer case, striking a balance between size and performance.
Compatibility
Compatibility is another crucial factor when choosing between these two products. The Thermalright TL-S12W X3 can be used universally as a case fan or in conjunction with CPU coolers, making it versatile for various setups. Alternatively, the Thermalright Assassin X 120 SE is specifically designed as a CPU cooler, compatible with a range of Intel and AMD sockets, including 115X, 1200, 1700, and AM4. This targeted compatibility ensures that the Assassin X 120 SE will fit right into most systems, making it a dedicated solution for CPU cooling.
Installation
Installation processes differ for the two products. The Thermalright TL-S12W X3 comes as a package of three fans, including necessary mounting screws and an instruction manual, which simplifies the setup for users looking to improve airflow in their cases. Conversely, the Thermalright Assassin X 120 SE includes metal fasteners for both Intel and AMD platforms, which may require a bit more attention during installation due to its more complex mounting system. However, both products are designed with user-friendliness in mind, ensuring a relatively straightforward installation experience.
Price Point
Price is a significant consideration for consumers. The Thermalright TL-S12W X3 is priced at C$19.59, making it an affordable choice for those looking to add efficient cooling to their systems without breaking the bank. In contrast, the Thermalright Assassin X 120 SE has a higher price of C$24.29, reflecting its more advanced cooling capabilities and additional features. While the Assassin X 120 SE offers superior performance, the TL-S12W X3 provides excellent value for users who need basic cooling.
Noise Levels
Noise levels can greatly affect the user experience, especially for those seeking a quiet computing environment. The Thermalright TL-S12W X3 operates at a maximum noise level of 23.2 dBA, which is relatively quiet and suitable for typical use. The Thermalright Assassin X 120 SE, while slightly louder at 25.6 dBA, still offers a balance of performance and noise control. Users prioritizing silence might lean towards the TL-S12W X3, while those requiring more cooling power may accept the slight increase in noise from the Assassin X 120 SE.
Which should you buy?
When deciding between the Thermalright TL-S12W X3 CPU Fan and the Thermalright Assassin X 120 SE ARGB CPU Air Cooler, consider your specific cooling needs and system requirements. If you are looking for an affordable, versatile case fan that provides decent airflow and quiet operation, the TL-S12W X3 is an excellent choice. However, if you require efficient cooling for a high-performance CPU and are willing to invest a bit more, the Assassin X 120 SE offers superior airflow and advanced design features. Ultimately, your decision should hinge on whether you need a simple case fan or a dedicated CPU cooler for demanding applications.
