The SCYTHE Big Shuriken 4 Low Profile CPU Cooler is priced at $32.99, making it a competitive option in the CPU cooler market. This cooler is designed for compact builds, such as Mini-ITX PCs, and offers compatibility with a range of devices including desktops, laptops, and servers. Its dimensions are 4.7" x 4.8" x 2.6", and it has a noise level of 31.78 dB, which reviewers have noted as being relatively quiet for its performance.
The cooler features 6 heat pipes, allowing for efficient thermal dissipation, which is particularly effective for users who may be upgrading from older models like the Shuriken 3. Additionally, it supports Intel LGA 1851 and AMD AM5 sockets, broadening its usability for various CPU setups. Overall, the SCYTHE Big Shuriken 4 combines performance with a compact design, making it an appealing choice for those with space constraints.
Overview of the Thermalright Peerless Assassin 120 Mini Black
The Thermalright Peerless Assassin 120 Mini Black CPU Cooler is priced slightly higher at $34.39, presenting a compelling choice with its advanced features. This cooler incorporates AGHP technology and 6 heat pipes, which enhance its cooling capabilities by addressing gravitational effects on heat dissipation. Its dimensions are 4.92" x 5.31" x 5.31", making it a bit taller than the SCYTHE model, and it operates at a noise level of 25.6 dB, which is quieter than the SCYTHE cooler.
The Peerless Assassin also features a 120mm PWM fan that operates at a speed of 1500 RPM, providing an airflow of 66.87 CFM. This makes it suitable for various CPU sockets, including AMD AM4 and AM5, as well as Intel LGA 1851, 1700, and more. With a robust design and effective cooling technology, the Thermalright Peerless Assassin 120 Mini Black offers a solid performance for those looking for a reliable CPU cooler.
Design and Build Quality
When it comes to design, the SCYTHE Big Shuriken 4 showcases a low-profile structure that fits well in tight spaces. Its compact size of 4.7" x 4.8" x 2.6" allows for easy installation in Mini-ITX cases without sacrificing performance. The cooler's aesthetic is sleek and functional, appealing to users who prioritize space-saving solutions.
In contrast, the Thermalright Peerless Assassin 120 Mini Black has a more substantial presence due to its larger dimensions of 4.92" x 5.31" x 5.31". Its fully blackened body with an antioxidant coating adds a modern touch, while the CNC precision micro-engraved copper base enhances its visual appeal. While the larger size may limit compatibility with certain compact cases, it also suggests a more robust thermal performance due to the increased surface area for heat dissipation.
Cooling Performance
Cooling performance is critical for any CPU cooler, and both products excel in this area. The SCYTHE Big Shuriken 4 employs 6 heat pipes to efficiently dissipate heat, making it a strong performer for its size. Users have noted that it cools better than its predecessor, the Shuriken 3, ensuring that even under load, it maintains optimal temperatures for CPUs.
On the other hand, the Thermalright Peerless Assassin 120 Mini Black leverages its AGHP technology to enhance cooling efficiency. Its 12cm performance fan pushes a substantial 66.87 CFM airflow, which is more than adequate for maintaining low temperatures. The combination of advanced heat pipe technology and a high-performance fan grants the Peerless Assassin an edge in cooling capabilities, especially for high-performance CPUs.
Noise Levels
Noise levels are a key consideration for users looking for a quiet computing experience. The SCYTHE Big Shuriken 4 operates at a noise level of 31.78 dB, which is relatively quiet but may be noticeable in a quiet room or during idle conditions. Users appreciate its balance of cooling efficiency and noise management, making it a suitable choice for those who prioritize a low-noise environment.
Conversely, the Thermalright Peerless Assassin 120 Mini Black is quieter, operating at a maximum noise level of 25.6 dB. This lower noise output is a significant advantage for users who are highly sensitive to sound, especially in environments where silence is preferred, such as home offices or media centers. The quieter operation combined with effective cooling makes the Peerless Assassin an appealing option for noise-conscious users.
Compatibility and Installation
Both the SCYTHE Big Shuriken 4 and the Thermalright Peerless Assassin 120 Mini Black offer broad compatibility with various CPU sockets. The SCYTHE model supports Intel LGA 1851 and AMD AM5 sockets, making it versatile for different builds. Its compact design simplifies installation in smaller cases, making it user-friendly for those who may not have extensive experience with CPU cooler installations.
The Thermalright Peerless Assassin 120 Mini Black is compatible with a wider range of sockets, including Intel LGA 1150, 1151, 1200, and AMD AM4/AM5. This extensive compatibility ensures that it can cater to most modern CPU setups. However, its larger size may require more careful consideration during installation in tighter spaces, possibly making it a bit more challenging than the SCYTHE cooler for some users.
Price Comparison
In terms of pricing, the SCYTHE Big Shuriken 4 is currently available for $32.99, which makes it a cost-effective option for users on a budget. It is about 1.17% cheaper than the Thermalright Peerless Assassin 120 Mini Black, priced at $34.39. While the price difference is not substantial, it may influence buyers who are looking for the best value for their money without compromising on performance.
The slightly higher price of the Thermalright model may be justified by its advanced cooling technology and quieter operation. Users willing to invest a little more may find that the additional features of the Peerless Assassin provide enhanced performance and overall satisfaction.
Which should you buy?
Choosing between the SCYTHE Big Shuriken 4 and the Thermalright Peerless Assassin 120 Mini Black ultimately depends on your specific needs.
