Overview of the Products

In this comparison, we will examine two CPU coolers: the i3/i5/i7 LGA115x CPU Heatsink and the Thermalright Assassin X120 Refined SE. The former is priced at $9.99, making it a budget-friendly option, while the latter comes in at $17.90, which is about 79% more expensive. Both coolers are designed to enhance the cooling efficiency of Intel processors, but they have different specifications and features that may appeal to different users.

Design and Build Quality

The i3/i5/i7 LGA115x CPU Heatsink features an aluminum heatsink and is designed for easy installation with a tool-free push pin mechanism. This model is specifically tailored for Intel's LGA 115x series, ensuring compatibility with several generations of Intel processors. In contrast, the Thermalright Assassin X120 Refined SE boasts a more robust design with 4 heat pipes and a PWM fan, providing efficient cooling with a noise level of ≤25.6dB(A). The Assassin X120 is made from aluminum and includes metal fasteners for secure installation on both Intel and AMD platforms, making it a versatile choice.

Cooling Performance

Cooling performance is a critical factor when choosing a CPU cooler. The i3/i5/i7 LGA115x CPU Heatsink is suitable for processors with a TDP (Thermal Design Power) of up to 65W, which covers a range of Intel i3, i5, and i7 CPUs. However, the Thermalright Assassin X120 Refined SE is designed for greater performance, featuring 4 heat pipes that utilize AGHP technology to enhance heat dissipation and combat inverse gravity effects. This cooler can handle a wider range of heat outputs, making it a better option for users with high-performance CPUs or those who plan to overclock.

Compatibility

Compatibility can significantly influence your choice of CPU cooler. The i3/i5/i7 LGA115x CPU Heatsink is compatible with Intel's LGA 1200, 1151, 1150, 1155, and 1156 sockets, making it a solid choice for users with older Intel systems. On the other hand, the Thermalright Assassin X120 Refined SE supports a broader range of sockets, including Intel's LGA 1150, 1151, 1155, 1200, 1700, and AMD's AM4/AM5. This versatility allows users to consider the Assassin X120 as a longer-term investment for future upgrades.

Noise Levels

Noise levels are an essential consideration for many users, especially those who prioritize a quiet computing environment. The i3/i5/i7 LGA115x CPU Heatsink does not provide explicit noise specifications, but its simpler design may lead to quieter operation under low loads. In contrast, the Thermalright Assassin X120 Refined SE features a PWM fan that operates at a maximum noise level of ≤25.6dB(A). This fan is designed to provide efficient cooling while maintaining a quiet ambiance, making it a suitable choice for users who desire a balance between performance and noise.

Price Comparison

The i3/i5/i7 LGA115x CPU Heatsink is priced at $9.99, making it a very affordable option for budget-conscious consumers. In contrast, the Thermalright Assassin X120 Refined SE is available for $17.90, which is about 79% more expensive than its counterpart. While the price difference is significant, the Thermalright cooler offers enhanced features, cooling performance, and compatibility, which may justify the higher cost for users who require more robust cooling solutions.

Brand Reputation

Brand reputation can play a crucial role in consumer decisions. ZYZMOON, the manufacturer of the i3/i5/i7 LGA115x CPU Heatsink, may not be as widely recognized as Thermalright, which has over 20 years of development experience and a strong presence in both domestic and international markets. Thermalright's focus on research and development in computer accessories, including CPU coolers, enhances its credibility. This established reputation may provide consumers with more confidence when investing in the Thermalright Assassin X120 Refined SE.

User Experience and Installation

User experience and ease of installation are vital factors to consider. The i3/i5/i7 LGA115x CPU Heatsink features a simple tool-free push pin installation, making it accessible for users who may not be familiar with CPU cooler setups. Conversely, the Thermalright Assassin X120 Refined SE offers a more complex installation process due to its multiple components and compatibility with both Intel and AMD platforms. While the installation may take a bit longer, the benefits of improved cooling performance may offset the initial setup time.

Which should you buy?

Choosing between the i3/i5/i7 LGA115x CPU Heatsink and the Thermalright Assassin X120 Refined SE ultimately depends on your specific needs and budget. If you are looking for an economical solution for lower TDP processors and prefer a straightforward installation, the i3/i5/i7 LGA115x CPU Heatsink is a solid choice at $9.99. However, if you require superior cooling performance, versatility, and a reputable brand, the Thermalright Assassin X120 Refined SE at $17.90 offers a compelling option, especially for users with demanding CPU requirements or future upgrade plans.
