Overview of SCYTHE Big Shuriken 4 and Thermalright Assassin X 120R SE V2
The SCYTHE Big Shuriken 4 Low Profile CPU Cooler is priced at $32.99, while the Thermalright Assassin X 120R SE V2 CPU Cooler comes at a significantly lower price of $16.59, making it about 50% cheaper. Both coolers are designed to provide efficient cooling for desktop and laptop CPUs, but they cater to slightly different needs and preferences.
The SCYTHE Big Shuriken 4 boasts a compact size of 4.7" x 4.8" x 2.6" and is particularly well-suited for Mini-ITX PC builds. It features 6 heat pipes, which enhance its cooling performance compared to its predecessor, the Shuriken 3. On the other hand, the Thermalright Assassin X 120R SE V2, with a height of 148mm, combines a larger cooling surface area with 4 heat pipes and a quieter fan operation, making it an attractive option for standard-sized cases.
Cooling Performance Comparison
When it comes to cooling performance, the SCYTHE Big Shuriken 4 utilizes 6 heat pipes, which provide improved thermal management, especially in low-profile builds. This cooler is rated for a maximum thermal design power of 200W, allowing it to handle higher performance CPUs effectively. Reviewers have noted its silent operation, rated at 31.78dB, which is beneficial for users who prioritize quiet computing.
Conversely, the Thermalright Assassin X 120R SE V2 features 4 heat pipes and a fan speed of 1550 RPM, delivering a maximum airflow of 66.17 CFM while maintaining a low noise level of up to 25.6dB. This makes the Thermalright cooler not only effective in keeping temperatures down but also quieter than many competitors. Users looking for a balance between cooling efficiency and noise levels might find this product appealing.
Size and Compatibility
Size is a crucial factor when choosing a CPU cooler, especially for compact builds. The SCYTHE Big Shuriken 4 has a low profile of 67mm, making it an excellent choice for Mini-ITX systems or builds with limited vertical space. It supports both Intel LGA 1851 and AMD AM5 sockets, ensuring compatibility with modern CPUs.
In contrast, the Thermalright Assassin X 120R SE V2 measures 120(L)x71(W)x148(H)mm, making it more suitable for standard ATX cases. It supports a wider range of Intel and AMD sockets, including LGA1150 through LGA1851 and AM4/AM5. This versatility allows users to install the cooler across various system builds, which is a significant advantage for those who may upgrade their components frequently.
Noise Levels
Noise levels are crucial for gamers and professionals who work in quieter environments. The SCYTHE Big Shuriken 4 operates at 31.78dB, which is relatively quiet but not the quietest option on the market. Users may find it suitable for general use but could be noticeable during intensive tasks.
On the other hand, the Thermalright Assassin X 120R SE V2 shines in this category, boasting a maximum noise level of just 25.6dB. This cooler is designed with S-FDB bearings that help reduce vibration and noise, making it an excellent choice for those who want a high-performance cooler without compromising on sound levels.
Design and Aesthetics
Design and aesthetics can significantly affect the overall appeal of a CPU cooler. The SCYTHE Big Shuriken 4 has a minimalist design that fits seamlessly into most builds, especially those focused on compactness. Its low-profile height and silver finish give it a clean, understated look.
In contrast, the Thermalright Assassin X 120R SE V2 features an RGB PWM fan, which adds a customizable lighting element to your PC build. This cooler's design is more traditional, with an aluminum heat sink that offers a balance between performance and style, appealing to users who enjoy a visually striking setup.
Installation Process
Both coolers are designed for ease of installation, but the approaches differ. The SCYTHE Big Shuriken 4 is noted for its compatibility with Mini-ITX setups and straightforward installation process, which is a plus for first-time builders. Its compact size simplifies fitting within tight spaces.
The Thermalright Assassin X 120R SE V2 also includes metal fasteners for Intel and AMD platforms, ensuring a secure fit. It offers clear installation instructions, which can be a boon for users unfamiliar with cooler installations. However, due to its larger size, it may require more careful planning regarding case compatibility.
Price Analysis
Price is a significant differentiator between the two products. The SCYTHE Big Shuriken 4 is available for $32.99, while the Thermalright Assassin X 120R SE V2 is priced at $16.59. This means that the SCYTHE cooler is about 99% more expensive than the Thermalright option. For budget-conscious consumers or those looking for a cost-effective cooling solution, the Thermalright cooler presents a compelling case.
While the SCYTHE cooler offers more heat pipes and a slightly higher thermal capacity, the substantial price difference might lead many to consider whether those features justify the higher expense, especially for typical gaming or workstation needs.
Which should you buy?
Choosing between the SCYTHE Big Shuriken 4 and the Thermalright Assassin X 120R SE V2 ultimately depends on your specific needs and preferences. If you're building a compact Mini-ITX system and require a low-profile cooler with excellent performance, the SCYTHE Big Shuriken 4 is a strong candidate. However, if you're looking for a quieter, more affordable solution that fits into a standard-sized case, the Thermalright Assassin X 120R SE V2 is an exceptional choice. Both coolers offer solid performance; your decision should hinge on budget, case compatibility, and noise preferences.
