Overview of the SCYTHE Big Shuriken 4 and Thermalright Peerless Assassin 120
The SCYTHE Big Shuriken 4 is priced at $32.99, while the Thermalright Peerless Assassin 120 is available for $45.90, making the SCYTHE cooler about 28% cheaper. Despite the price difference, both products are designed to provide effective cooling solutions for CPUs. The SCYTHE Big Shuriken 4 is a low-profile cooler, making it ideal for compact builds, while the Thermalright Peerless Assassin 120 boasts a dual tower design for enhanced cooling efficiency.
Design and Build Quality
When it comes to design, the SCYTHE Big Shuriken 4 features a compact form factor at 4.7" x 4.8" x 2.6", suited for mini-ITX setups. In contrast, the Thermalright Peerless Assassin 120 is larger, with dimensions of 138mm x 125mm x 162mm, making it compatible with standard ATX chassis. The Peerless Assassin’s dual tower and dual fans are designed for superior heat dissipation, while the SCYTHE's low profile is advantageous for space-constrained builds.
Cooling Performance
The cooling performance of both products is impressive, but they cater to different user needs. The SCYTHE Big Shuriken 4 is equipped with six heat pipes, enabling it to cool faster than its predecessor, the Shuriken 3. On the other hand, the Thermalright Peerless Assassin 120 employs six pure copper heat pipes and operates at a fan speed of 1850 RPM, promising excellent performance with a noise level of ≤25.6 dB. This makes the Peerless Assassin particularly effective for users seeking quiet yet powerful cooling.
Compatibility
In terms of compatibility, both coolers support a range of CPU sockets. The SCYTHE Big Shuriken 4 is compatible with Intel LGA 1851 and AMD AM5, which covers many modern CPUs. The Thermalright Peerless Assassin 120 offers broader compatibility, supporting AM4/AM5 and Intel sockets including LGA 1700, 1851, 1150, 1151, 1155, 1156, and 1200. This makes the Peerless Assassin more versatile for users with different hardware configurations, ensuring a wider appeal.
Noise Levels
Noise levels are an important consideration for many users, particularly those building a quiet PC. The SCYTHE Big Shuriken 4 operates at a noise level of 31.78 dB, which is reasonable for a cooler of its type. Meanwhile, the Thermalright Peerless Assassin 120 is quieter, with a maximum noise level of ≤25.6 dB. This approximately 20% lower noise level in the Peerless Assassin can be a deciding factor for users prioritizing a silent operation, especially in noise-sensitive environments.
Installation Process
The installation process for both coolers is relatively straightforward, but the Thermalright Peerless Assassin 120 provides more detailed guidance. The Peerless Assassin comes with dual-platform mounting clips, ensuring compatibility across multiple platforms and simplifying the installation process. The SCYTHE Big Shuriken 4, while also designed for easy setup, may require more careful consideration due to its low-profile nature, particularly in tight spaces. Users may find the clearer instructions and versatile mounting options of the Peerless Assassin a significant advantage.
Price Point
In terms of pricing, the SCYTHE Big Shuriken 4 is more budget-friendly at $32.99 compared to $45.90 for the Thermalright Peerless Assassin 120. This represents a significant cost difference of about $12.91, making the SCYTHE cooler a more attractive option for budget-conscious consumers. However, the price of the Peerless Assassin may be justified by its advanced features, superior cooling performance, and quieter operation, appealing to users willing to invest more for enhanced capabilities.
Which should you buy?
Choosing between the SCYTHE Big Shuriken 4 and the Thermalright Peerless Assassin 120 ultimately depends on your specific needs and build requirements. If you're looking for a cost-effective, low-profile cooler suitable for compact builds, the SCYTHE Big Shuriken 4 is a great choice. However, if you require robust cooling performance, wider compatibility, and quieter operation, the Thermalright Peerless Assassin 120 stands out despite its higher price. Consider your setup, budget, and cooling demands to make the best decision for your CPU cooling needs.
