Dimension comparison
Overview of the Products
When it comes to CPU cooling, the Intel i3/i5/i7 LGA115x CPU Heatsink by ZYZMOON and the Thermalright Peerless Assassin 120 SE V2 CPU Cooler present two distinct options for users. The ZYZMOON cooler is priced at C$19.99, making it a budget-friendly choice, while the Thermalright model is significantly more expensive at C$54.90. Both coolers are designed to maintain optimal temperatures for CPUs, but they cater to different performance needs and user preferences.
Design and Build Quality
The Intel i3/i5/i7 LGA115x CPU Heatsink features a straightforward design with an aluminum heatsink, emphasizing ease of installation with pre-applied thermal paste and tool-free push pin installation. In contrast, the Thermalright Peerless Assassin 120 SE V2 boasts a more robust construction, featuring an aluminum fin structure on a pure copper base. Its dimensions of 125mm x 135mm x 155mm allow for more efficient heat dissipation, while the 6 heat pipes are specifically designed to combat the inverse gravity effect, providing enhanced cooling performance.
Cooling Performance
Cooling performance is critical for any CPU cooler, and the Thermalright Peerless Assassin 120 SE V2 excels in this area with a TDP rating of up to 265W, significantly higher than the Intel cooler, which is suitable for CPUs with a TDP of up to 65W. The dual thickened PWM fans in the Thermalright model can achieve an airflow of 88.19 CFM at a noise level of 29.5 dB(A), ensuring effective cooling even during high-load scenarios. The ZYZMOON cooler, while adequate for lower TDP processors, may struggle under more demanding conditions.
Compatibility
Compatibility is an essential factor to consider when choosing a CPU cooler. The Intel i3/i5/i7 LGA115x CPU Heatsink is designed specifically for Intel Core i3, i5, and i7 processors with socket types LGA 1150, 1151, 1155, and 1156. This makes it a solid choice for users with older Intel systems. On the other hand, the Thermalright Peerless Assassin 120 SE V2 supports a wider range of sockets, including Intel LGA 1851, 1700, 1200, and 115X, as well as AMD AM4 and AM5. This versatility makes the Thermalright cooler a better option for users who may upgrade their systems in the future.
Installation Process
Installation can greatly influence user experience, and here, the ZYZMOON cooler shines with its tool-free push pin installation method, allowing for quick and easy setup. This is particularly beneficial for novice users who may not be familiar with complex installation processes. Conversely, the Thermalright Peerless Assassin 120 SE V2, while also designed for ease of installation, comes with metal fasteners that may require additional effort and time. Users who appreciate a straightforward installation may favour the ZYZMOON cooler for its simplicity.
Price Consideration
Price is often a decisive factor in product selection. The ZYZMOON cooler is priced at C$19.99, making it an appealing option for budget-conscious consumers or those with lower cooling needs. In comparison, the Thermalright Peerless Assassin 120 SE V2, priced at C$54.90, is significantly more expensive but justifies the price with advanced cooling capabilities and broader compatibility. Users must weigh their cooling requirements against their budget when making a choice between these two products.
Noise Levels
Noise levels can affect the overall computing experience, especially for users who value a quiet environment. The Thermalright Peerless Assassin 120 SE V2 operates at a maximum noise level of 29.5 dB(A), which is relatively quiet for a high-performance cooler. In contrast, the ZYZMOON cooler’s noise level is not specified but is generally expected to be lower due to its simpler design and lower fan speeds. For users prioritizing quiet operation, the ZYZMOON may seem like a preferable option, while those needing superior cooling will find the Thermalright cooler's noise levels acceptable given its performance.
Which should you buy?
In deciding between the Intel i3/i5/i7 LGA115x CPU Heatsink and the Thermalright Peerless Assassin 120 SE V2, the choice ultimately hinges on your specific needs. If you are seeking an economical cooling solution primarily for lower TDP Intel processors, the ZYZMOON cooler at C$19.99 is a sound choice. However, if you require enhanced cooling performance for more demanding tasks or future-proofing with broader compatibility, the Thermalright Peerless Assassin 120 SE V2, priced at C$54.90, offers superior features and performance.
