CPU cooler Thermalright Assassin X 120 Refined SE CPU Cooler

Thermalright Assassin X 120 Refined SE is an air cooler for CPU, aimed at mid-range gaming and work configurations, where you seek good performance without unnecessary effects. The combination of a 120 mm fan, low noise level, and wide RPM range makes it flexible for both quiet and more demanding systems. It works with the most popular sockets, including AM4/AM5 and LGA 1700, so there’s no drama when upgrading. The lack of RGB and the entirely black design make it simple and easy to fit into any build.

What you get is a well-balanced 120 mm air cooler that can spin from 500 to 1550 RPM, meaning it can stay almost inaudible at idle and ramp up only under serious load. With an airflow of 66.17 CFM and maximum pressure of 1.53 mmH2O, the fan is suitable for denser towers and more restricted airflow in the case. A maximum noise level of 25.6 dBA means that even under load it won’t “whine” annoyingly in your ear. The dynamic fluid bearing ensures smoother operation and a long lifespan for the fan, which is important if you want the machine to run stably for years.

• Air cooling with a fan 120 x 120 x 25 mm, which is the gold standard for good compatibility with most cases.
• Wide speed range 500–1550 RPM, allowing quiet operation in light mode and more serious airflow during gaming or rendering.
• Airflow 66.17 CFM, sufficient to expel hot air from the radiator and maintain stable temperatures under load.
• Maximum static pressure 1.53 mmH2O, which helps the air effectively pass through the dense fins of the radiator.
• Low noise level up to 25.6 dBA, suitable for people who want their computer to be quiet even under more serious tasks.
• Compatibility with multiple sockets – AM4, AM5, LGA 115x, LGA 1200, LGA 1700, LGA 1851, making it a good option for future upgrades.
• 4-pin connector with PWM control, so you can set a fan curve through BIOS or software according to your preferences.
• Black color scheme without RGB, ideal for clean builds or systems that don’t need lighting.
• Dynamic fluid bearing for less vibration, quieter operation, and longer fan life.

It is suitable for mid-range gaming and work PC configurations where you want decent cooling without water and without paying for unnecessary LED effects. If you are aiming for extreme overclocking or a very hot high-end CPU, you will probably need to look towards more massive towers or water cooling, but for normal use and stable all-core boost, this solution is completely logical.

It combines quiet operation, adequate airflow, and wide compatibility with sockets in a compact 120 mm format. Its strongest weapon is the balance between performance, noise, and practical, clean design.
