Air cooler Thermalright Assassin X 120 Refined SE ARGB 12 cm Black

The Thermalright Assassin X 120 Refined SE ARGB 12 cm Black is a single-tower CPU air cooler engineered to provide steady thermal management for mainstream and compact desktop systems. The cooler combines a 120 mm fan with a fluid dynamic bearing and a design tuned for balanced airflow and static pressure. Its black finish and addressable RGB illumination offer visual integration with modern builds while maintaining focus on effective heat dissipation.

Advantages

Designed for quiet operation, the fan runs at a rotational range that supports effective cooling without producing intrusive noise. The cooler delivers a measurable static pressure level suitable for pushing air through dense fin stacks and typical case airflow restrictions. Its compact footprint is intended to reduce interference with memory modules and to fit in many mid-tower and small-form-factor enclosures. The ARGB lighting provides customizable visual accents compatible with common motherboard controllers.

Suitable for

• Cooling mainstream desktop CPUs in gaming or productivity systems
• Small- to mid-tower builds where space for large towers is limited
• Systems that require a balance between low noise and reliable thermal performance
• Builds that use ARGB lighting for coordinated aesthetics

Key specifications

• Fan size: 120 mm
• Maximum rotational speed: up to 1550 RPM
• Bearing type: fluid dynamic bearing
• Maximum air pressure: 1.53 mmH2O
• Color: black with addressable RGB lighting
• Form factor: single-tower air cooler

How to use

Install the cooler following the mounting instructions that match your motherboard socket. Position the cooler so airflow aligns with your case ventilation, typically drawing air through the fin stack toward an exhaust fan. Connect the fan power cable to the CPU fan header and the ARGB cable to a compatible lighting header or controller. Apply a thin, even layer of thermal compound between the CPU heat spreader and the cooler base before fastening the mounting brackets to ensure proper thermal contact.

Usage recommendations

For stable performance, verify BIOS fan curve settings or use motherboard software to tune fan speed profiles based on CPU temperature. Ensure sufficient case airflow by maintaining intake and exhaust pathways and by cleaning dust filters regularly to preserve static pressure and airflow efficiency.
