Thermalright CPU Cooler Assassin X 120 Refined SE PLUS - LGA1851/AM5

Thermalright Assassin X 120 Refined SE PLUS is an air CPU cooler from mid to high range, aimed at stable and quiet cooling of modern gaming and workstation configurations. It comes with two 120 mm fans and supports the latest sockets, including LGA 1851 and AM5, making it a good option for current platforms. The noise level is only 25.6 dBA, so you can keep your machine under load without annoying background noise. The black design allows you to easily combine it with most cases and themes without clashing visually.

What you get: two 120 mm fans with S-FDB Bearing, which combine good lifespan and lower noise, especially during long operation. The speed range from 500 to 1550 RPM gives you flexibility – lower speeds for quiet idle and higher for stable temperatures under load. The airflow up to 124.17 CFM (or 210.97 m³/h) and pressure 1.53 mmH2O mean that the cooler can effectively draw heat even in more densely packed cases. 4-pin connectors allow PWM control, so the motherboard can automatically adjust the speeds according to your CPU temperature. Compatibility with a wide range of sockets makes the cooler a good investment if you are considering a future platform upgrade.

• Tower-type air cooling with two fans 120 x 120 x 25 mm, providing serious airflow through the radiator.
• Compatibility with multiple platforms – LGA 1150/1151/1155/1156/1200/1700/1851 and AM4/AM5, so you can use it when changing CPU and motherboard.
• Fans with S-FDB Bearing, which are oriented towards longer life and quieter operation during extended gaming or rendering.
• Speed range from 500 to 1550 RPM, allowing a balance between low noise and more serious cooling depending on the load.
• Maximum airflow up to 124.17 CFM / 210.97 m³/h and static pressure 1.53 mmH2O for effective heat dissipation through the radiator and case.
• Low noise level of only 25.6 dBA, suitable for configurations where silence is a priority – streaming, work, or night gaming.
• 4-pin PWM connectors for intelligent speed control through the motherboard, without the need for constant manual adjustments.
• Sleek black color that fits most builds without visually dominating the rest of the hardware.

This cooler is suitable for gaming and workstation configurations on current platforms, where you seek a good balance between cooling and noise. It is also suitable if you plan to switch to LGA 1851 or are already on AM5/AM4 and want something more serious than the stock cooler. If you are aiming for extreme overclocking or a completely silent system under full load, you will likely look towards larger towers or liquid cooling, but for mainstream CPUs, this is a very reasonable step up.

The most sensible aspect here is the combination of dual 120 mm setup, low noise, and wide compatibility with modern sockets. You install it once and are set for several generations of platforms ahead.
