Overview of the Thermalright Peerless Assassin 120 Black CPU Air Cooler
The Thermalright Peerless Assassin 120 Black CPU Air Cooler is priced at $38.90, about 17% more expensive than the SCYTHE Big Shuriken 4. It features a more robust cooling design, including six heat pipes and dual PWM fans, which significantly enhance its cooling capabilities. With dimensions of 4.92" x 5.31" x 6.18", it provides a larger heatsink surface area, ensuring effective heat dissipation. This cooler is compatible with a wide range of Intel and AMD sockets, including LGA 1700, 115X, 1851, and AM4/AM5, making it a versatile choice for various builds. Additionally, it operates at a low noise level of 25.6 dB, contributing to a quieter computing experience.
Performance Comparison: Cooling Efficiency
In terms of cooling efficiency, the SCYTHE Big Shuriken 4 utilizes six heat pipes to improve heat dissipation, allowing it to cool CPUs with a Thermal Design Power (TDP) of up to 200 watts. However, the Thermalright Peerless Assassin 120 Black excels in this area, boasting a TDP capability of 245 watts due to its advanced AGHP technology. This allows for better performance under heavy loads, making it a better choice for high-performance CPUs. The dual PWM fans of the Peerless Assassin also create an airflow of 66.17 CFM, compared to the SCYTHE’s single fan setup, indicating a more robust cooling solution for users who push their systems to the limits.
Noise Levels: A Quiet Operation
When it comes to noise levels, the SCYTHE Big Shuriken 4 operates at 31.78 dB, which is relatively quiet but higher than the Thermalright Peerless Assassin's 25.6 dB. This difference may be significant for users prioritizing silent operation in their setups. The Peerless Assassin's dual fan design not only improves cooling performance but also contributes to its quieter operation, making it a better choice for users who require a peaceful working or gaming environment.
Design and Aesthetics
The SCYTHE Big Shuriken 4 features a low-profile design that is particularly beneficial for compact builds. Its dimensions allow for easy installation in tight spaces, which is a significant advantage for Mini-ITX systems. On the other hand, the Thermalright Peerless Assassin 120 Black showcases a more traditional tower design, which, while bulkier, can provide better heat dissipation overall. The black aluminum heatsink with a modern aesthetic appeals to users looking for a visually striking cooler that matches contemporary gaming rigs.
Installation and Compatibility
Both coolers offer broad compatibility with various CPU sockets, but the installation process may vary. The SCYTHE Big Shuriken 4 supports Intel LGA 1851 and AMD AM5, making it suitable for modern builds. Meanwhile, the Thermalright Peerless Assassin 120 Black supports a wider array of sockets, including LGA 1700, 115X, 2066, and AM4/AM5, providing greater flexibility for users with different CPU setups. This ease of installation is further enhanced by the inclusion of metal fasteners in the Peerless Assassin, which may simplify the mounting process.
Price Considerations
The SCYTHE Big Shuriken 4 is currently priced at $32.99, making it a more budget-friendly option compared to the Thermalright Peerless Assassin 120 Black, which costs $38.90. The approximately $5 difference may be significant for those on a tighter budget but could be justified by the enhanced performance and features offered by the Peerless Assassin. Ultimately, the decision may hinge on whether the user prioritizes cost savings or superior cooling performance.
Which should you buy?
Choosing between the SCYTHE Big Shuriken 4 and the Thermalright Peerless Assassin 120 Black ultimately depends on your specific needs and budget. If you're looking for a compact, low-profile cooler that performs adequately for general use and is more budget-friendly, the SCYTHE Big Shuriken 4 is an excellent choice. However, if you require superior cooling performance, particularly for high-end CPUs, and are willing to pay a bit more for enhanced features and quieter operation, the Thermalright Peerless Assassin 120 Black would be the better investment.
