Overview of CPU Coolers
In this comparison, we will examine the SCYTHE Big Shuriken 4 Low Profile CPU Cooler and the Thermalright Peerless Assassin 120 SE V2 CPU Cooler. The SCYTHE Big Shuriken 4 is priced at $32.99, making it about 17% cheaper than the Thermalright Peerless Assassin, which retails for $38.99. Both coolers are designed for efficient thermal management in modern computing systems, but they cater to different needs and preferences.
Design and Build Quality
The SCYTHE Big Shuriken 4 features a compact low-profile design with dimensions of 4.7" x 4.8" x 2.6", making it an excellent choice for small form factor builds and Mini-ITX PCs. This design allows for compatibility with a variety of setups, including desktops, laptops, and servers. In contrast, the Thermalright Peerless Assassin 120 SE V2 has a dual tower structure that stands at 155mm high, which not only enhances cooling efficiency but also gives it a more robust appearance. Users looking for a sleek and compact option may prefer the SCYTHE cooler, while those desiring superior cooling performance might lean towards the bulkier Thermalright model.
Cooling Performance
When it comes to cooling performance, both coolers feature six heat pipes designed to effectively dissipate heat. The SCYTHE Big Shuriken 4 is noted for its ability to cool faster than its predecessor, the Shuriken 3, offering good value and silence during operation. However, the Thermalright Peerless Assassin 120 SE V2 has dual 120mm PWM fans that can run up to 1850 RPM, providing a high airflow of 88.89 CFM. This means that while the SCYTHE cooler is excellent for low-profile builds, the Thermalright model is better suited for high-load scenarios like gaming and multitasking, thanks to its robust cooling capabilities.
Noise Levels
In terms of noise levels, the SCYTHE Big Shuriken 4 operates at a sound level of 31.78 dBA, which is relatively quiet for a CPU cooler. This makes it a great option for users who prioritize a silent computing environment. The Thermalright Peerless Assassin 120 SE V2, on the other hand, has a maximum noise level of 29.5 dBA, which is slightly quieter than the SCYTHE model. Although both coolers maintain a low noise profile, the Thermalright cooler edges out slightly in this category, making it a viable choice for noise-sensitive applications.
Compatibility
Compatibility is an essential factor when choosing a CPU cooler. The SCYTHE Big Shuriken 4 supports Intel LGA 1851 and AMD AM5 sockets, making it a flexible option for various systems. The Thermalright Peerless Assassin 120 SE V2 also boasts broad compatibility, supporting both AMD AM4/AM5 and Intel LGA1851/1700 platforms. This extensive socket support means that both coolers can cater to a wide range of builds, but the Thermalright model offers a slight edge due to its support for both AMD and Intel platforms, making it more versatile for users with mixed setups.
Installation Process
The installation process can greatly affect the user experience when setting up a CPU cooler. The SCYTHE Big Shuriken 4 is designed for easy installation, particularly in tight spaces, thanks to its low-profile nature. This makes it user-friendly for those who may not have extensive experience with building PCs. Conversely, the Thermalright Peerless Assassin 120 SE V2 may require a bit more space and effort to install due to its dual tower design. However, its design allows for enhanced cooling once installed, making it worth the extra effort for users seeking top performance.
Target Audience
The SCYTHE Big Shuriken 4 is ideal for users who require a space-saving solution without compromising too much on cooling performance. It caters to Mini-ITX builds and silent computing environments. On the other hand, the Thermalright Peerless Assassin 120 SE V2 is targeted more towards gamers and power users who need reliable cooling under heavy workloads. With its dual fans and robust cooling capabilities, it is better suited for high-performance systems.
Price Consideration
The price difference between these two coolers is quite notable. At $32.99, the SCYTHE Big Shuriken 4 is a budget-friendly option that provides solid performance for low-profile applications. In comparison, the Thermalright Peerless Assassin 120 SE V2 is priced at $38.99, making it about 17% more expensive. While the higher price may reflect its superior cooling capabilities, users on a tighter budget may find the SCYTHE cooler to be a more appealing choice without sacrificing too much performance.
Which should you buy?
In conclusion, choosing between the SCYTHE Big Shuriken 4 and the Thermalright Peerless Assassin 120 SE V2 depends on your specific needs. If you are looking for a compact, budget-friendly cooler suitable for small builds and silent operation, the SCYTHE Big Shuriken 4 is an excellent choice. However, if you require more robust cooling performance for gaming or high-load tasks and are willing to invest a bit more, the Thermalright Peerless Assassin 120 SE V2 stands out with its superior airflow and compatibility. Ultimately, both coolers offer distinct advantages, making them valuable options in the CPU cooler market.
