The Thermalright Assassin X 120 Refined SE ARGB is a high-performance single-tower CPU air cooler engineered for efficient thermal management across modern Intel and AMD platforms. Featuring 4x6mm AGHP heat pipes, a TL-C12C-S PWM fan spinning up to 1550 RPM, and a 148mm-tall aluminum heatsink with copper base, it delivers up to 66.17 CFM of airflow while maintaining a quiet 25.6 dBA noise level. Compatible with Intel LGA 115x, 1200, 1700, 1851 and AMD AM4, AM5 sockets, the Thermalright Assassin X 120 Refined SE ARGB offers versatile installation for a wide range of builds.

Cooling Performance

The cooler utilizes four 6mm AGHP (Anti-Gravity Heat Pipe) units that efficiently transfer heat from the CPU surface to the aluminum fin stack. The copper base plate ensures direct contact with the processor IHS for maximum heat conduction. With a maximum airflow of 66.17 CFM and air pressure of 1.53 mm H2O, the Thermalright Assassin X 120 Refined SE ARGB handles demanding thermal loads from mainstream and high-performance CPUs alike.

Fan Specifications

The included TL-C12C-S fan measures 120mm x 120mm x 25mm and weighs 120g. It operates at a maximum rated speed of 1550 RPM ±10% using a 4-pin PWM connector for automatic motherboard-controlled speed adjustment. The S-FDB (Sealed Fluid Dynamic Bearing) construction provides smooth, long-lasting operation while keeping noise output at just 25.6 dBA. The fan draws a maximum of 0.20 A, ensuring efficient power usage.

ARGB Lighting

The Thermalright Assassin X 120 Refined SE ARGB features vibrant addressable RGB lighting through a 3-pin ARGB connector, compatible with major motherboard RGB synchronization software. The colorful illumination effect enhances the visual appeal of any PC build while maintaining the cooler’s focus on thermal performance and quiet operation.

Socket Compatibility and Installation

This cooler supports a broad range of CPU sockets including Intel LGA 115x, 1200, 1700, and 1851, as well as AMD AM4 and AM5 platforms. The 148mm heatsink height ensures compatibility with most mid-tower and full-tower cases. Metal fasteners for both Intel and AMD platforms are included to achieve secure and stable installation, making the Thermalright Assassin X 120 Refined SE ARGB a flexible choice for new and upgraded builds.

Build Quality and Design

Constructed with an aluminum heatsink cover and a copper base plate, the single-tower design measures 120mm long, 46mm wide, and 148mm tall with a heatsink weight of 630g. The AGHP technology ensures consistent cooling performance regardless of mounting orientation, whether the motherboard is installed horizontally or vertically. The combination of premium materials and thoughtful engineering makes this cooler a reliable component for sustained CPU performance under load.
