## Long description

The Thermalright Assassin X 120 Refined SE is an aluminium air cooler with a 120 mm fan engineered for effective CPU heat dissipation. The unit combines a compact heatsink design with a high-performance fan that delivers focused airflow and elevated static pressure to improve thermal transfer from the processor to the fins. Finished in black aluminium, the cooler is dimensioned for compatibility with a wide range of mainstream desktop platforms and offers a balance between cooling capability and case fitment.
Advantages
The Fluid Dynamic Bearing fan reduces operational noise while maintaining stable rotation and long service life. The cooler’s 120 mm fan provides a maximum air pressure of 1.53 mmH2O, which helps push air through the fin stack and across heatpipes for consistent cooling under moderate to high loads. The aluminium construction combines light weight with corrosion resistance and a uniform black finish for compatibility with varied system aesthetics.
Suitable for
Everyday desktop computing and office systems that require reliable CPU cooling
Mid-range gaming PCs where a compact cooler is needed for RAM and motherboard clearance
Compact builds and small to medium form-factor cases with support for a 120 mm cooler
Key specifications

How to use
Install the cooler following the motherboard and case manufacturer’s instructions: secure the mounting bracket appropriate for the target CPU socket, apply a thin, even layer of thermal compound on the CPU heatspreader, position the heatsink so that the fan airflow aligns with the system’s case ventilation, and tighten mounting screws to the specified torque. Connect the fan cable to the CPU\_FAN or appropriate header on the motherboard to allow speed control and monitoring. Ensure sufficient clearance for memory modules and other components before finalizing the installation.
Usage recommendations
For optimal thermal performance, use a controlled fan curve in the BIOS or a motherboard utility to adjust RPMs based on CPU temperature. Regularly inspect and clean dust from the fan and fin stack to maintain airflow efficiency. Verify case airflow direction and maintain unobstructed intake and exhaust paths to maximize cooling effectiveness.
