Introduction to CPU Coolers

When it comes to cooling solutions for your CPU, selecting the right cooler can significantly impact both performance and longevity. In this comparison, we pit the Thermalright Assassin X 120 SE ARGB CPU Air Cooler against the Thermalright Aqua Elite 360 V3 Liquid CPU Cooler. The former is priced at C$24.29, while the latter comes in at a higher cost of C$91.70. This article will explore their features, performance, installation, and more to help you make the best choice for your build.

Design and Build Quality

The design of a CPU cooler can affect not just aesthetics but also performance. The Thermalright Assassin X 120 SE ARGB features a compact design with dimensions of 125mm x 71mm x 148mm, making it suitable for medium-sized cases. Weighing 0.645 kg, it includes aluminum heat sinks and metal fasteners for durability. In contrast, the Aqua Elite 360 V3 boasts a larger design with a 360mm radiator and three 120mm fans, delivering a robust cooling solution. The pump head design is unique, featuring an octagonal shape and ARGB lighting, which adds a visually appealing element to your setup. Overall, while the Assassin X is more compact, the Aqua Elite offers a more advanced cooling system.

Cooling Performance

Cooling performance is critical for maintaining optimal CPU temperatures. The Assassin X 120 SE is designed for CPUs with a thermal design power (TDP) of 125 to 225W, making it suitable for mid-range processors. The cooler’s 4x6mm heat pipes and efficient PWM fan can spin at up to 1550 RPM, providing an airflow of 66.17 CFM while maintaining a noise level of ≤25.6 dB(A). On the other hand, the Aqua Elite 360 V3 is engineered for superior cooling with its 360mm radiator and three fans capable of 1500 RPM. It also offers a similar airflow of 66.17 CFM but does so at a lower noise level of ≤23 dBA. This makes the Aqua Elite a better choice for users looking for top-tier cooling performance.

Noise Levels

Noise levels can affect your computing experience, especially in quiet environments. The Thermalright Assassin X 120 SE operates at a maximum noise level of ≤25.6 dB(A), which is quite acceptable for most users. However, the Aqua Elite 360 V3 edges out in this category with a maximum noise level of ≤23 dBA, making it quieter during operation. The lower noise level is achieved thanks to its advanced pump and fan design, which focuses on minimizing vibrations. If a silent operation is a priority for you, the Aqua Elite may be the better option.

RGB Lighting and Aesthetics

For many users, RGB lighting is not just a feature but an essential part of their PC build's aesthetics. The Thermalright Assassin X 120 SE comes equipped with ARGB PWM fans, allowing for customizable lighting that can sync with your motherboard. This adds a dynamic visual element to your setup. The Aqua Elite 360 V3 also offers excellent RGB lighting, with fans and the pump head featuring ARGB sync capabilities that can create a stunning light show. Both coolers excel in this category, but the Aqua Elite's pump design may provide a more visually striking effect.

Installation Process

The installation process can vary greatly between air and liquid coolers. The Assassin X 120 SE is designed for straightforward installation, compatible with Intel sockets (115X, 1200, 1700) and AMD AM4 platforms. It includes all necessary mounting hardware, making it user-friendly for novices. In contrast, the Aqua Elite 360 V3 requires a bit more effort due to its liquid cooling design. It supports a wider range of sockets, including AMD AM4/AM5 and Intel LGA1150 to LGA2066, but the installation process may be more complex for first-time builders. If you prefer a hassle-free installation, the Assassin X could be the right choice.

Price and Value

Price is a significant factor when choosing between these two coolers. The Thermalright Assassin X 120 SE is very affordable at C$24.29, making it an excellent entry-level option for budget-conscious users or those building a mid-range system. On the other hand, the Aqua Elite 360 V3 is priced at C$91.70, reflecting its advanced cooling capabilities and additional features. While the Aqua Elite offers superior cooling performance and aesthetics, it comes at a higher cost. The decision ultimately depends on your budget and cooling requirements.

Compatibility

Compatibility is crucial when selecting a CPU cooler. The Thermalright Assassin X 120 SE supports Intel sockets (115X, 1200, 1700) and AMD AM4, making it versatile for various builds. The Aqua Elite 360 V3 has broader compatibility, supporting more socket types, including AMD AM4/AM5 and Intel LGA1150 to LGA2066. This makes the Aqua Elite a better option for users who might upgrade their systems in the future. However, if your build is compatible with the Assassin X, it offers a solid performance at a lower price point.

Which should you buy?

In conclusion, the choice between the Thermalright Assassin X 120 SE ARGB CPU Air Cooler and the Thermalright Aqua Elite 360 V3 Liquid CPU Cooler largely depends on your specific needs and budget. If you are looking for an affordable, compact solution that provides decent cooling performance, the Assassin X is a great option. Conversely, if you prioritize superior cooling performance, quieter operation, and stunning aesthetics, the Aqua Elite is worth the investment. Ultimately, both coolers are excellent in their own right, but your choice should reflect your cooling requirements and budget constraints.
