Dimension comparison
Overview of Products
In the realm of CPU cooling solutions, the Intel i3/i5/i7 LGA115x CPU Heatsink and the Thermalright Peerless Assassin 120 Black CPU Air Cooler cater to different needs and preferences. The Intel cooler, priced at C$19.99, offers an economical option for users with lower thermal design power (TDP) CPUs, while the Thermalright model, priced at C$54.90, aims to deliver superior cooling performance for more demanding setups.
Cooling Performance
When it comes to cooling efficiency, the Thermalright Peerless Assassin 120 Black clearly stands out. It features a double tower design and two PWM fans, providing an air flow of up to 66.17 CFM at a maximum noise level of 25.6 dB(A). In contrast, the Intel cooler is designed for CPUs with a TDP of 65W or less, primarily targeting budget-conscious users or those with less power-hungry processors. While the Intel cooler is adequate for its intended purpose, it cannot compete with the advanced cooling capabilities of the Thermalright model.
Design and Build Quality
In terms of design, the Thermalright cooler boasts a robust construction with an aluminum heat sink and a full electroplating reflow welding process. This not only enhances its aesthetic appeal but also improves heat dissipation efficiency. The Intel heatsink, also made from aluminum, is simpler in design and intended for more straightforward installation. While both products are well-constructed, the Thermalright’s design elements suggest a focus on performance, making it a more durable and efficient choice for higher-end CPUs.
Installation Process
The installation process varies significantly between the two products. The Intel cooler promotes an easy, tool-free push pin installation, making it accessible for users who may not have extensive technical expertise. On the other hand, the Thermalright Peerless Assassin comes with metal fasteners for Intel and AMD platforms, which requires a bit more effort but ensures a more secure mounting. Users willing to invest extra time in setup may appreciate the added stability of the Thermalright cooler.
Compatibility
Compatibility is a crucial factor to consider when selecting a CPU cooler. The Intel cooler is specifically designed for LGA 115x sockets, catering to Intel's i3, i5, and i7 processors. Meanwhile, the Thermalright Peerless Assassin supports a wider range of sockets, including Intel’s LGA 1150, 1151, 1155, 1156, 1200, 1700, and AMD’s AM4 and AM5. This broader compatibility makes the Thermalright a more versatile option, particularly for users who may upgrade their systems in the future.
Thermal Management Features
Both coolers offer features aimed at enhancing thermal management. The Thermalright Peerless Assassin employs six pure copper sintered heat pipes, significantly improving heat transfer efficiency compared to the Intel cooler, which primarily relies on its aluminum heatsink. The Peerless Assassin also utilises AGHP technology to mitigate inverse gravity effects, further enhancing cooling performance. In contrast, while the Intel cooler is equipped with pre-applied thermal paste, it lacks the advanced thermal management features found in the Thermalright model.
Price Point Analysis
Price is often a decisive factor in product selection. The Intel i3/i5/i7 LGA115x CPU Heatsink is priced at C$19.99, making it an attractive option for budget-conscious consumers or those with lower-performance CPUs. Conversely, the Thermalright Peerless Assassin 120 Black is priced at C$54.90, which reflects its advanced features and capabilities. While the Thermalright may seem expensive, its design and performance justify the higher price point for users needing more effective cooling solutions.
Which should you buy?
Choosing between the Intel i3/i5/i7 LGA115x CPU Heatsink and the Thermalright Peerless Assassin 120 Black boils down to your specific needs and budget. If you are looking for a cost-effective cooling solution for a lower TDP CPU and prefer a straightforward installation, the Intel cooler is a practical choice. However, if you are building a high-performance system or plan on overclocking, the superior cooling capabilities, design, and broader compatibility of the Thermalright Peerless Assassin make it the better investment. Ultimately, the right choice will depend on your system requirements and cooling demands.
