Price Comparison

The i3/i5/i7 LGA115x CPU Heatsink is priced at $9.99, while the Thermalright Assassin X 120R SE V2 CPU Cooler is priced at $16.59. This makes the Thermalright cooler about 66% more expensive than the ZYZMOON heatsink. For budget-conscious buyers, the ZYZMOON heatsink offers a more affordable cooling solution, especially for those with a limited budget or lower power requirements. On the other hand, the Thermalright cooler, while pricier, may provide additional performance benefits that justify the cost for users looking for enhanced cooling capabilities.

Cooling Performance

The Thermalright Assassin X 120R SE V2 boasts a high-performance fan that operates at a speed of 1550 RPM, enabling an airflow of 66.17 CFM and maintaining a noise level of 25.6 dB(A). In contrast, the i3/i5/i7 LGA115x CPU Heatsink does not specify its airflow or noise levels but is designed for CPUs with a thermal design power (TDP) of up to 65W. While the ZYZMOON heatsink is adequate for lower-end CPUs, the Thermalright's advanced features, such as its four heat pipes and efficient fan performance, suggest it is better suited for demanding applications and overclocking scenarios.

Design and Build Quality

The ZYZMOON heatsink features an aluminum design with pre-applied thermal paste, allowing for easy installation via a tool-free push pin mechanism. Meanwhile, the Thermalright Assassin X 120R SE V2 is constructed with a pure copper base and aluminum heat sink, equipped with metal fasteners to ensure a secure installation on both Intel and AMD platforms. The inclusion of S-FDB bearings in the Thermalright cooler enhances its durability and reduces noise during operation. Overall, while both products are well-made, the Thermalright's higher-end materials and construction may provide better longevity and performance.

Compatibility

The i3/i5/i7 LGA115x CPU Heatsink is compatible with Intel's LGA1200, LGA1151, LGA1150, LGA1155, and LGA1156 sockets, supporting a variety of Intel Core processors including i3, i5, and i7 models. The Thermalright Assassin X 120R SE V2 offers broader compatibility, supporting not only Intel sockets (LGA1150, LGA1151, LGA1155, LGA1156, LGA1200, LGA1700, and LGA1851) but also AMD's AM4 and AM5 sockets. This wider compatibility makes the Thermalright cooler suitable for a more diverse range of systems, appealing to users who may switch platforms in the future.

Installation Process

The installation process for both coolers is designed to be straightforward. The ZYZMOON heatsink features a tool-free push pin installation method, making it accessible even for those with minimal technical skills. On the other hand, the Thermalright Assassin X 120R SE V2 provides detailed installation instructions and video guidance, allowing users to install it correctly, even though it may require slightly more effort due to the inclusion of metal fasteners. This difference can be significant for users who prefer ease of installation versus those who value a more secure setup.

Noise Levels

The Thermalright Assassin X 120R SE V2 operates at a maximum noise level of 25.6 dB(A), indicating that it is designed for quiet performance without sacrificing cooling efficiency. In contrast, the i3/i5/i7 LGA115x CPU Heatsink does not specify its noise levels, which leaves uncertainty regarding its operational sound. For users sensitive to noise or those looking for a quieter computing environment, the Thermalright cooler is likely the better option, as its design focuses on low noise while maximizing airflow.

Aesthetic Appeal

When it comes to aesthetics, the Thermalright Assassin X 120R SE V2 features RGB lighting, which can enhance the visual appeal of a gaming or high-performance build. The ZYZMOON heatsink, while functional, does not offer any RGB features and is more utilitarian in appearance. For users who value a visually striking setup, the Thermalright cooler may be more appealing, while the ZYZMOON heatsink serves those who prioritize function over form.

Which should you buy?

Choosing between the i3/i5/i7 LGA115x CPU Heatsink and the Thermalright Assassin X 120R SE V2 ultimately depends on your specific needs and budget. The ZYZMOON heatsink is an economical choice for users with low-power processors and basic cooling requirements, priced at $9.99. However, if you are looking for superior cooling performance, better compatibility across platforms, and quieter operation, the Thermalright cooler, priced at $16.59, may be worth the investment. Each option has its strengths, so consider your priorities—whether it's cost, performance, or aesthetics—before making a decision.
