Overview of Thermalright Assassin X 120 SE ARGB CPU Air Cooler

The Thermalright Assassin X 120 SE ARGB CPU Air Cooler is designed for efficient cooling performance and aesthetic appeal. Priced at C$24.29, this cooler features a compact design with dimensions of 125mm x 71mm x 148mm, making it suitable for medium-sized computer cases. With a weight of 0.645kg, it is robust enough to handle a TDP of 125 to 225W, ensuring that it can effectively dissipate heat from high-performance CPUs.

In addition to its performance capabilities, the Assassin X 120 SE incorporates advanced technology such as 4×6mm heat pipes that utilise AGHP techniques to counteract inverse gravity effects. This air cooler is compatible with a variety of CPU sockets, including Intel 115X, 1200, 1700, and AMD AM4, providing versatility for different builds.

Overview of Thermalright TL-S12RW X3 CPU Fan

The Thermalright TL-S12RW X3 CPU Fan is a cost-effective cooling solution priced at C$19.90. With a size of 120mm x 120mm x 25mm, this fan is designed to enhance airflow within your system while maintaining a low noise level of 23.2dBA when operated at its maximum speed of 1500RPM. This combination of size and performance makes it an ideal choice for both case and CPU cooling applications.

Featuring S-FDB V2 bearings, the TL-S12RW X3 is engineered to reduce vibration and noise, ensuring a quieter operation. It provides an airflow of 47.6 CFM, which is adequate for removing heat from the computer chassis and CPU, thus adding to the overall cooling efficiency of a system.

Cooling Performance Comparison

When it comes to cooling performance, the Thermalright Assassin X 120 SE ARGB CPU Air Cooler excels with its TDP rating of 125 to 225W, making it suitable for high-performance CPUs that generate significant heat. Its design, including 4×6mm heat pipes, enhances heat dissipation, contributing to its superior cooling capabilities.

In contrast, the Thermalright TL-S12RW X3 CPU Fan offers an airflow of 47.6 CFM, which is efficient for general cooling needs but does not match the cooling power of the Assassin X 120 SE. While the fan is designed to work well in tandem with CPU coolers and case ventilation, it is more of a supplemental cooling component rather than a standalone solution for high-TDP CPUs.

Noise Levels and Acoustic Performance

Noise levels are a critical consideration for many computer users, especially in quieter environments. The Thermalright Assassin X 120 SE operates at a noise level of 25.6 dB(A), delivering a balance between cooling efficiency and audible performance. This makes it suitable for users who want effective cooling without excessive noise.

On the other hand, the TL-S12RW X3 operates slightly quieter at a maximum noise level of 23.2 dB(A). This slight advantage may appeal to users prioritising quiet operation. However, the difference in noise levels is minimal, and both products are designed to operate quietly, enhancing the overall user experience in noise-sensitive environments.

Build Quality and Design

In terms of construction, the Thermalright Assassin X 120 SE is built with high-quality materials, including an aluminum heat sink and industrial-strength PBT + PC materials for durability. Its design features metal fasteners for both Intel and AMD platforms, ensuring easy installation and a secure fit.

The Thermalright TL-S12RW X3, while constructed with a focus on aesthetics and functionality, features a unique pure white design with ARGB lines that can enhance the visual appeal of a build. The fan's soft silicone feet also contribute to its build quality by reducing vibration and noise, but it lacks the robust design elements found in the Assassin X 120 SE.

Compatibility and Installation

Compatibility is a significant factor when choosing cooling solutions. The Thermalright Assassin X 120 SE supports a wide range of CPU sockets, including Intel’s 115X, 1200, 1700, and AMD’s AM4. This extensive compatibility ensures that it can be used in various builds without the need for additional mounting hardware.

The TL-S12RW X3 is versatile as well, serving not only as a case fan but also complementing CPU coolers to enhance cooling efficiency. However, it does not have the same level of socket versatility as the Assassin X 120 SE, making it more suitable for specific applications rather than universal compatibility across different CPU platforms.

Price and Value Proposition

The Thermalright Assassin X 120 SE is priced at C$24.29, reflecting its capabilities as a high-performance CPU cooler. Given its cooling efficiency, build quality, and versatility, many users will find that it offers excellent value for the price, especially for high-TDP systems.

In contrast, the TL-S12RW X3 is more budget-friendly at C$19.90. It provides decent performance for general cooling needs but lacks the high-end capabilities of the Assassin X 120 SE. For users on a tighter budget or those who do not require extreme cooling, the TL-S12RW X3 represents good value, particularly when used in conjunction with other cooling components.

Which should you buy?

Deciding between the Thermalright Assassin X 120 SE ARGB CPU Air Cooler and the Thermalright TL-S12RW X3 CPU Fan ultimately depends on your specific needs. If you require robust cooling for a high-performance CPU, the Assassin X 120 SE, with its superior TDP rating and efficient heat dissipation, is the clear choice at C$24.29. However, if you are looking for an affordable and aesthetically pleasing fan that can support general cooling needs, the TL-S12RW X3 at C$19.90 serves as a solid option, especially as a complement to a more powerful cooler.
