Overview of the Products

In this comparison, we will look at two CPU air coolers: the CPU Air Cooler with 4X6mm Heat Pipes and the Thermalright Assassin X120 Refined SE CPU Air Cooler. The first cooler is priced at $23.99, while the latter is available for $17.90, making the Thermalright model about 25% cheaper. Each cooler has unique features that cater to different needs, making this comparison essential for potential buyers.

Compatibility and Socket Support

Both coolers are designed to support a wide range of CPU sockets, which is crucial for users looking to upgrade or build PCs. The CPU Air Cooler with 4X6mm Heat Pipes boasts compatibility with Intel LGA 1700, 1851, 1155, 1156, 2011, and 2066 as well as AMD's AM5, AM4, and AM3 series. In contrast, the Thermalright Assassin X120 Refined SE supports similar Intel sockets and AMD AM4 and AM5 as well. This universality ensures that both products cater to a broad user base, although the first cooler offers a slightly wider array of Intel socket compatibility.

Cooling Performance

Cooling performance is a critical factor for any CPU cooler, and both models deliver effectively. The CPU Air Cooler with 4X6mm Heat Pipes features four 6mm heat pipes designed to dissipate heat efficiently, ensuring optimal CPU performance under heavy workloads. On the other hand, the Thermalright Assassin X120 employs AGHP technology with similar 6mm heat pipes, claiming to solve inverse gravity effects and enhance cooling efficiency. While both coolers are engineered for effective heat dissipation, the direct comparison of their cooling capabilities may vary based on specific use cases and configurations.

Noise Levels and Operation

When it comes to noise levels, both coolers operate quietly, but the Thermalright Assassin X120 has a slight edge. The CPU Air Cooler with 4X6mm Heat Pipes operates at a maximum noise level of 26 dB(A), while the Thermalright model reaches a maximum of only 25.6 dB(A). This difference indicates that the Thermalright cooler may provide a slightly quieter operation, which can be particularly beneficial for users who prioritize a silent computing environment.

Installation Process

Installation ease can significantly affect user experience, and both coolers are designed for straightforward setups. The CPU Air Cooler with 4X6mm Heat Pipes features a non-disassembly fan installation, allowing for hassle-free setup without removing the motherboard or RAM. In comparison, the Thermalright Assassin X120 is also equipped with metal fasteners designed for easy installation across various platforms. While both coolers emphasize user-friendly installation, the non-disassembly feature of the first cooler may offer added convenience for those concerned about RAM clearance.

Build Quality and Durability

Durability is a vital aspect to consider in CPU coolers, and both products offer robust constructions. The CPU Air Cooler with 4X6mm Heat Pipes is built with premium materials, ensuring long-lasting reliability. Meanwhile, the Thermalright Assassin X120 is constructed with industrial-grade materials and features S-FDB bearings for extended service life. Although both coolers promise durability, the Thermalright's emphasis on industrial strength materials may appeal to users seeking a more rugged option.

Airflow and Fan Efficiency

Airflow is another critical factor in cooling efficiency, and both coolers perform admirably in this regard. The CPU Air Cooler with 4X6mm Heat Pipes has a maximum airflow of 68.2 CFM, while the Thermalright Assassin X120 provides a slightly lower maximum airflow of 66.17 CFM. Although the difference is marginal, higher airflow can contribute to better cooling performance, especially in high-performance setups. Thus, users who prioritize maximum airflow might lean towards the first cooler.

Which should you buy?

Choosing between the CPU Air Cooler with 4X6mm Heat Pipes and the Thermalright Assassin X120 Refined SE ultimately depends on individual preferences and specific needs. If you're looking for broader socket compatibility and slightly better airflow, the CPU Air Cooler at $23.99 may be the right choice. Conversely, if you prefer a quieter operation and a more budget-friendly option, the Thermalright Assassin X120 at $17.90 is an excellent pick. Both coolers are capable performers, ensuring that regardless of your choice, your CPU will remain well-cooled.
