Heatsink/Radiator Thermalright Assassin X 120 REFINED SE WHITE 12 cm 1550 RPM 25.6 dB
The Thermalright Assassin X 120 REFINED SE WHITE is a compact tower heatsink with a 120 mm fan designed for effective CPU cooling in desktop systems. Built for compatibility with a wide range of modern consumer sockets, it delivers active airflow and static pressure suitable for dissipating heat from high-performance processors. The fan uses a fluid dynamic bearing to extend service life while keeping operational noise low. The cooler combines aluminium fin stacks with a black finish and white fan accents for a neutral aesthetic in many chassis layouts.
This cooler provides balanced thermal performance and acoustics, achieving up to 1550 RPM and a rated noise level of 25.6 dB. With a maximum airflow of 66.17 cfm and air pressure of 1.53 mmH2O, it is optimized for maintaining lower CPU temperatures under sustained loads. The fluid dynamic bearing enhances longevity and reduces bearing-related noise over time. Its compact 120 mm fan and tower layout make it suitable for mid-tower and many smaller enclosures without compromising clearance for memory modules or motherboard components.
Install the heatsink according to the motherboard and cooler manufacturer instructions, ensuring correct socket mounting and even application of thermal paste between CPU heatspreader and cooler base. Mount the 120 mm fan on the heatsink in the intended airflow direction and connect the fan header to a CPU_FAN or compatible PWM header on the motherboard. Confirm clearance for RAM modules and nearby components before final tightening, then power on the system and monitor temperatures and fan speed in BIOS or a hardware monitoring utility to verify proper operation.
For reliable cooling and quieter operation, ensure the fan header is configured for PWM control and use a motherboard fan curve that increases speed gradually with CPU temperature. Clean dust from the fin stack and fan periodically to maintain airflow. When used in compact cases, verify front-to-back airflow to avoid recirculation of warm air.
