Overview of the Products

In this comparison, we will look at the i3/i5/i7 LGA115x CPU Heatsink by ZYZMOON and the Thermalright Assassin X 120R Digital ARGB Black CPU Cooler. The ZYZMOON heatsink is priced at $9.99, whereas the Thermalright cooler is available for $24.90. This highlights a significant price difference, with the Thermalright option being about 149% more expensive.

Cooling Efficiency

The i3/i5/i7 LGA115x CPU Heatsink is designed for Intel processors with a thermal design power (TDP) of up to 65W. It provides sufficient cooling for various Intel i-series CPUs and includes a pre-applied thermal paste, ensuring efficient heat transfer right out of the box. On the other hand, the Thermalright Assassin X 120R excels in heat dissipation with a more advanced design featuring four heat pipes and a high-speed fan capable of reaching 2000 RPM, which allows it to handle more demanding workloads and higher TDPs effectively.

Design and Aesthetics

The design of the Thermalright Assassin X 120R is notably superior in terms of aesthetics and functionality. It features a digital screen top cover that displays real-time CPU and GPU temperatures, adding an element of user interactivity and monitoring. In contrast, the i3/i5/i7 LGA115x CPU Heatsink adopts a more traditional look with a straightforward aluminum heatsink design, which, while functional, lacks the modern flair and features of its competitor.

Ease of Installation

When it comes to installation, both products emphasize user-friendliness. The i3/i5/i7 LGA115x CPU Heatsink boasts a tool-free push pin installation, making it accessible for users looking for simplicity. The Thermalright Assassin X 120R also includes installation accessories and has a design intended for compatibility with various Intel and AMD sockets, but it requires the original backplate for AMD installations, which might complicate matters for some users.

Noise Levels

Noise levels can be a crucial factor in CPU coolers. The Thermalright Assassin X 120R operates at a noise level of ≤ 29.8 dB(A), which is relatively quiet for a cooler with such performance capabilities. The i3/i5/i7 LGA115x CPU Heatsink does not provide specific noise level metrics, but given its lower performance specifications, it may operate at lower noise levels during typical use. For users who prioritize silence, the Thermalright cooler represents a more sophisticated option.

Compatibility

Compatibility is another area where these products differ significantly. The i3/i5/i7 LGA115x CPU Heatsink is compatible with a range of Intel sockets, including LGA1200, 1151, 1150, 1155, and 1156, making it versatile within its specific category. In contrast, the Thermalright Assassin X 120R supports both Intel (including LGA 1700 and 1851) and AMD sockets (AM4/AM5), offering broader compatibility for users who may switch platforms in the future.

Price and Value

The price difference between these two coolers is significant, with the i3/i5/i7 LGA115x CPU Heatsink costing $9.99 and the Thermalright Assassin X 120R priced at $24.90. This means the Thermalright cooler is about 149% more expensive than the ZYZMOON option. While the Thermalright offers advanced features and better cooling capabilities, the ZYZMOON cooler may represent better value for users with less demanding CPU cooling needs or those on a tight budget.

Which should you buy?

The decision between the i3/i5/i7 LGA115x CPU Heatsink and the Thermalright Assassin X 120R ultimately depends on your specific needs and budget. If you are looking for a budget-friendly option that provides basic cooling for low to mid-range Intel CPUs, the ZYZMOON heatsink at $9.99 is a solid choice. However, if you require superior cooling performance, advanced features like a digital screen, and broader compatibility with both Intel and AMD platforms, the Thermalright Assassin X 120R at $24.90 is worth the investment.
