Price Comparison

This makes the Thermalright cooler about 40% cheaper than its SCYTHE counterpart. If budget is a primary consideration, the Thermalright offers significant savings for those looking to upgrade their cooling solution without breaking the bank. However, the higher cost of the SCYTHE cooler may reflect additional features or performance enhancements that justify its price for some users.

Cooling Performance

In terms of cooling efficiency, the SCYTHE Big Shuriken 4 features six heat pipes designed to provide superior heat dissipation. This allows it to handle a thermal output of up to 200W, which is particularly beneficial for high-performance CPUs. The Thermalright Assassin King, on the other hand, utilizes five heat pipes and is also built to manage substantial cooling demands, although its maximum thermal output isn't specified. The SCYTHE cooler's design is noted for cooling faster than its predecessor, Shuriken 3, which may appeal to users seeking the latest technology for optimal performance.

Noise Levels

Noise is a crucial factor for many PC builders, and here the SCYTHE Big Shuriken 4 operates at a maximum noise level of 31.78dB. The Thermalright Assassin King is designed to be quieter, with a noise level capped at 25.6dB. This results in the Thermalright cooler being about 19% quieter than the SCYTHE model. For users who prioritize a silent computing environment, the Thermalright Assassin King may be the preferable choice, especially in noise-sensitive settings like home offices or media centers.

Size and Compatibility

The SCYTHE Big Shuriken 4 has compact dimensions of 4.7" x 4.8" x 2.6", making it an excellent option for Mini-ITX builds where space is at a premium. It supports both Intel LGA 1851 and AMD AM5 sockets, enhancing its versatility. Conversely, the Thermalright Assassin King 120 SE is slightly larger at 120(L)x73(W)x148(H)mm but still fits well within mid-sized cases. It supports a wider range of sockets, including multiple Intel and AMD configurations. Users with space constraints might lean towards the SCYTHE for its lower profile, while those needing broader compatibility may prefer the Thermalright.

Aesthetic Appeal

Aesthetics can play a significant role in the selection of a CPU cooler. The SCYTHE Big Shuriken 4 has a more utilitarian design, focusing solely on functionality without any RGB lighting. In contrast, the Thermalright Assassin King features ARGB lighting effects, allowing for customizable colors and lighting patterns, which can enhance the look of a gaming rig. For users who value visual aesthetics in their builds, the Thermalright may offer an attractive option that complements their system's design.

Brand Reputation

Both brands have established themselves in the cooling market. SCYTHE is recognized for its innovative designs and performance-driven products, particularly in low-profile cooling solutions. Thermalright has built a reputation over more than 20 years, focusing on high-quality cooling products that cater to both average users and enthusiasts. This brand credibility can influence purchasing decisions, with some users preferring to stick with a brand they trust based on previous experiences or reviews.

Ease of Installation

Ease of installation is vital for users looking to upgrade or build their systems. The SCYTHE Big Shuriken 4 is designed for quick installation across compatible sockets, which can be a plus for those who may not have extensive experience with PC building. Meanwhile, the Thermalright Assassin King includes metal fasteners for both Intel and AMD platforms, facilitating a straightforward installation process. Users who value a hassle-free setup may find both coolers relatively easy to install, though individual experiences may vary based on specific system configurations.

Which should you buy?

Choosing between the SCYTHE Big Shuriken 4 and the Thermalright Assassin King 120 SE ultimately depends on your specific needs and preferences. If you're looking for a compact cooler with superior thermal capacity and don't mind paying a bit more, the SCYTHE may be the right choice for you. However, if budget sensitivity, lower noise levels, and aesthetic appeal with customizable RGB lighting are your priorities, the Thermalright Assassin King stands out as a compelling option. Each cooler has its strengths, so consider your individual requirements carefully before making a decision.
