The Thermalright Peerless Assassin X 120 Refined SE Black CPU Air Cooler (Peerless Assassin X 120 Refined SE) is a high-performance single-tower cooling solution engineered to deliver exceptional thermal regulation for mainstream desktop processors. Combining a stealthy, fully blacked-out structural aesthetic with precise mechanical engineering, this component provides an optimized balance of cooling density and footprint versatility for modern systems.
The physical architecture implements a compact single-tower design featuring 51 aluminum fins bound to a precision nickel-plated C1100 pure copper base plate through four robust 6mm anti-gravity heatpipes. Driven by a high-pressure 120mm TL-C12C PWM fan utilizing premium Fluid Dynamic Bearings, it rapidly moves ambient air through concentrated cooling channels to safely dissipate thermal energy up to a solid 225W rating while keeping the system’s operational sound footprint ultra-low.
Key Features & Specifications
Advanced AGHP Anti-Gravity Heatpipes: Employs four premium 6mm copper heatpipes engineered with special internal capillary structures to guarantee unrestricted vapor-phase heat transfer regardless of vertical or horizontal chassis orientation.
Optimized Single-Tower Fin Density: Features an array of 51 finely spaced aluminum fins designed to broaden the effective surface area, maximizing cooling performance within restricted computer enclosure layouts.
High-Static Pressure PWM Fan: Powered by a color-matched 120mm TL-C12C fan that outputs up to 66.17 CFM of volumetric airflow to handle sharp processing load spikes efficiently.
Sealed Fluid Dynamic Bearings: S-FDB fan rotation architecture vastly reduces internal mechanical friction, capping maximum noise levels at a whisper-quiet 25.6 dBA while ensuring an extended operational lifecycle.
Universal Contact Fastener Array: Includes precise structural metal brackets offering uniform seating tension and out-of-the-box compatibility with current AMD AM5/AM4 and Intel LGA 1851/1700 platforms.
