Description
The Scythe Big Shuriken 4 (SCSK-4000) represents a significant evolution in low-profile cooling, engineered to meet the thermal demands of high-performance CPUs within space-constrained environments. Standing at a total height of just 67mm, this cooler utilizes a top-down airflow design that not only cools the processor but also provides secondary airflow to surrounding motherboard components like VRMs and M.2 SSDs. The upgraded heatsink architecture incorporates six 6mm copper heat pipes and a high-density aluminum fin stack, ensuring rapid heat transfer that rivals many larger tower coolers.
This cooling solution is specifically tailored for five key user groups:
- Small Form Factor (SFF) enthusiasts building in boutique Mini-ITX cases like the Fractal Terra or Louqe Ghost S1.
- Home Theater PC (HTPC) builders who require a silent operation profile for immersive media consumption.
- Professional workstation users utilizing compact desktop builds for content creation and rendering.
- Gamers seeking a reliable, high-performance alternative to stock coolers for Intel LGA 1700 or AMD AM5 platforms.
- System integrators looking for a high-compatibility cooler that simplifies installation in cramped chassis.
Technical Specifications and Compatibility:
- Dimensions: 120 x 122 x 67 mm (including fan).
- Heat Pipe Array: 6 x 6mm diameter high-efficiency copper heat pipes.
- Fan Model: Kaze Flex II 120 Slim AH PWM (15mm thickness).
- Fan Speed: 300 (±200) to 1900 (±10%) RPM.
- Airflow Performance: 51.98 CFM with a static pressure of 1.71 mmH2O.
- Noise Levels: Quiet operation ranging up to a maximum of 31.78 dBA.
- Socket Support: Intel LGA 1851, 1700, 1200, 115x; AMD AM5, AM4.
The user experience is centered around the H.P.M.S. VI (Hyper Precision Mounting System), which provides a secure and straightforward installation process with optimal contact pressure. The included Kaze Flex II 120 Slim fan features a Fluid Dynamic Bearing (FDB) for a 120,000-hour lifespan and integrated anti-vibration rubber pads to eliminate resonance. Its asymmetrical heatsink design is a critical feature, offset to ensure that the cooler does not overhang RAM slots or the primary PCIe slot, allowing for the use of high-profile memory modules without interference.
In a relational comparison, the Big Shuriken 4 offers a substantial performance boost over 47mm ultra-low-profile coolers by leveraging its additional surface area and two extra heat pipes. While standard tower coolers provide more raw thermal mass, they are physically incompatible with most SFF cases; the SCSK-4000 bridges this gap by offering near-tower performance in a footprint that fits almost any compact chassis. Compared to its predecessor, the Big Shuriken 3, this fourth-generation model features improved fan aerodynamics and native support for the latest Intel LGA 1851 and AMD AM5 sockets.
Frequently Asked Questions:
- Is the Scythe Big Shuriken 4 compatible with the new Intel LGA 1851 socket? Yes, the H.P.M.S. VI mounting system provides full out-of-the-box compatibility for LGA 1851 and LGA 1700.
- What is the total height of the cooler with the fan installed? The total height is exactly 67mm, making it suitable for cases with limited vertical clearance.
- Does this cooler interfere with tall RGB RAM? No, the asymmetrical design is specifically engineered to provide clearance for high-profile memory modules on most motherboards.
- Can the fan be replaced with a standard 25mm thick fan? Yes, though you would need to source longer fan clips or screws, and the total height would increase to 77mm.
- What is the warranty period for this product? The Scythe Big Shuriken 4 comes with a 3-year manufacturer warranty.
