Thermalright Peerless Assassin 120 SE Dual-Tower CPU Cooler

Thermalright Peerless Assassin 120 SE is a dual-tower air cooler for CPU, aimed at mid-range and more serious gaming and workstation configurations. With two 120 mm fans and broad support for modern sockets, this cooler is an easy choice if you want something serious above stock coolers. It operates in the range 500–1550 RPM, allowing a balance between silence and cooling. There is no RGB, so the focus is entirely on efficiency and practicality.

What you get

The two fans sized 120 x 120 x 25 mm are set to work in sync – at lower speeds your system stays quiet, and under load you can rely on stable airflow. The total airflow of up to 132.34 CFM is serious for air cooling and is suitable for CPUs with higher consumption, as long as they are within the officially supported by the socket. The noise level of up to 25.6 dBA is quite low for a dual cooler, which is a plus if you want your machine to not hum constantly. The 4-pin connector gives you PWM control through the motherboard, so you can set aggressive or quiet fan curves according to the system's purpose. Thanks to the support for AM4/AM5 and LGA 1700/1851, you can use it in both current Ryzen and new Intel configurations without worrying about changing when upgrading the platform.

• Dual-tower design with 2x 120 mm fans for greater heat dissipation area and more stable temperatures under prolonged load.
• Wide compatibility with CPU sockets – AM4, AM5, LGA 1200, LGA 115x, LGA 1700, LGA 1851 – a convenient choice for future platform upgrades.
• Wide speed range 500–1550 RPM, allowing quiet idle and more aggressive cooling under high load.
• Serious airflow of up to 132.34 CFM, suitable for cooling powerful CPUs in well-ventilated cases.
• Low noise level of up to 25.6 dBA, so even under load the system remains relatively quiet.
• Max. static pressure 1.53 mm H2O, which helps the air effectively pass through the dense radiator.
• Standard 4-pin PWM connector for full integration with motherboard fan control and easy profile management.

Who it is suitable for

Peerless Assassin 120 SE is a very good choice if you are building a gaming or workstation PC with a modern Intel or AMD CPU and want serious air cooling without entering the world of water systems. It is suitable for people who value a quiet operating mode but do not want to sacrifice temperatures during gaming or rendering. It is not for you if you are looking for an RGB show or super-compact cooling for small ITX cases.

The combination of dual-tower design, two 120 mm fans, high airflow, and low noise makes it a very balanced air cooler. If you prioritize efficiency and silence over lights and decoration, this is exactly the type of cooler.
