Price Comparison
When considering price, the Intel i3/i5/i7 LGA115x CPU Heatsink is notably the less expensive option, retailing at C$19.99 compared to the Thermalright Assassin X 120R SE Plus CPU Cooler, which is priced at C$25.59. This makes the ZYZMOON cooler a budget-friendly choice for users seeking to enhance their CPU cooling without breaking the bank. However, the price difference of C$5.60 could be justified by the Thermalright cooler's advanced features and technology that promise enhanced performance, particularly for users with higher cooling demands.
Cooling Performance
In terms of cooling performance, the Thermalright Assassin X 120R SE Plus is designed with four 6mm heat pipes that employ advanced AGHP technology. This innovation is intended to counteract the inverse gravity effect that can occur based on the cooler's orientation, ensuring consistent cooling regardless of installation position. Meanwhile, the Intel i3/i5/i7 LGA115x CPU Heatsink is suitable for processors with a thermal design power (TDP) of up to 65W, which may limit its effectiveness for more demanding CPUs. Users needing robust cooling for higher TDP processors may find the Thermalright cooler's capabilities more appealing.
Noise Levels
The Thermalright Assassin X 120R SE Plus boasts a maximum noise level of 25.6 dB(A), which is commendably low for a CPU cooler, ensuring a quieter computing environment. In contrast, the ZYZMOON cooler does not specify its noise levels, which may be a concern for users prioritizing a silent operation. If noise reduction is a priority in your PC build, the Thermalright model could be the better option, especially in environments where noise can be a distraction.
Fan Technology
The Thermalright Assassin X 120R SE Plus features two PWM fans, TL-C12C and TL-C12RB V2, which are designed to provide efficient cooling while maintaining low noise levels. The fans operate at speeds of 1550 RPM and 1500 RPM respectively, delivering airflow of up to 66.17 CFM. On the other hand, the Intel i3/i5/i7 LGA115x CPU Heatsink includes a single pre-applied thermal paste and a 4-pin PWM power connector for straightforward installation. While both coolers feature PWM technology for optimal performance, the dual fan configuration of the Thermalright cooler offers superior airflow and cooling efficiency.
Compatibility
When it comes to compatibility, the Thermalright Assassin X 120R SE Plus supports a wider range of CPU sockets, including Intel 1150/1151/1155/1156/1200/1700/17XX and AMD AM4/AM5. This versatility makes it a suitable choice for users with various setups. Conversely, the Intel i3/i5/i7 LGA115x CPU Heatsink is specifically designed for Intel's LGA 115x sockets and supports a range of Intel Core processors, but does not extend to AMD systems. For users who may consider future upgrades or have mixed setups, the broader compatibility of the Thermalright cooler could be a significant advantage.
Build Quality
The Thermalright Assassin X 120R SE Plus is constructed with industrial-strength materials, including PBT and PC, which contribute to its durability and longevity. It also features S-FDB bearings that reduce fan blade shaking and noise, enhancing the cooler's operational lifespan. The Intel i3/i5/i7 LGA115x CPU Heatsink, while functional, is primarily an aluminum heatsink that, although effective for its intended use, may not offer the same level of durability and performance under heavy loads as the Thermalright model. Users looking for long-lasting performance might find the build quality of the Thermalright cooler more reassuring.
Installation Process
Both coolers promise a straightforward installation process, but they differ in their approach. The Thermalright Assassin X 120R SE Plus comes with various mounting plates and fasteners for different CPU socket platforms, allowing for a more tailored installation experience. In contrast, the Intel i3/i5/i7 LGA115x CPU Heatsink features a tool-free push pin installation method, which simplifies the setup for users who prefer an easy and quick installation. However, the comprehensive support provided by Thermalright for various sockets may appeal to those looking for flexibility.
Which should you buy?
In conclusion, the choice between the Thermalright Assassin X 120R SE Plus and the Intel i3/i5/i7 LGA115x CPU Heatsink largely depends on your specific needs and budget. If you're looking for a cost-effective solution for lower TDP processors and prefer an easy installation, the ZYZMOON cooler could be a suitable option. However, for users seeking superior cooling performance, lower noise levels, broader compatibility, and enhanced durability, the Thermalright cooler justifies its higher price point.
