Thermalright Peerless Assassin 120 SE ARGB Dual-Tower

Thermalright Peerless Assassin 120 SE ARGB is a dual-tower air cooler for CPU, aimed at mid-range and more serious gaming and workstation configurations. Two 120 mm fans, high overall airflow of 132.34 CFM, and relatively low noise of just 25.6 dBA make it a good option if you want stable temperatures without a 'drone fan' next to your ear. The added 5V ARGB lighting allows you to connect it with the rest of the lighting in the case and arrange your aesthetics as you like. Thanks to the wide socket support, you can easily plan it for future upgrades.

What you get

The two included 120 mm fans with a range of 500–1550 RPM provide flexibility – they can spin slowly and quietly in idle, and under load, they can ramp up the RPMs and blow away the accumulated heat from the radiators. The total airflow of 132.34 CFM is serious for air cooling and helps the CPU maintain stable frequencies during longer gaming sessions or rendering. The noise level of 25.6 dBA means that even at higher RPMs, it won't be the loudest component in the case. The 4-pin PWM connector allows the motherboard to control the RPMs according to temperature, while the 5V ARGB line provides synchronization of the lighting with other ARGB components.

• Dual-tower air cooler with Air cooling type, suitable for serious gaming and workstation systems.
• Wide compatibility with CPU sockets – AM4, AM5, LGA 1700, LGA 1851, LGA 1200, LGA 115x, so you can use it for future upgrades as well.
• Two fans measuring 120 x 120 x 25 mm each, providing a balance between airflow, pressure, and compatibility with most cases.
• Wide RPM range of 500–1550 RPM, allowing for quiet operation during light tasks and more aggressive cooling under load.
• Total airflow of 132.34 CFM, suitable for cooling hotter processors and maintaining lower temperatures under load.
• Low noise level of 25.6 dBA, which helps keep the system quiet even with two fans on the cooler.
• Maximum static pressure of 1.53 mm H2O, useful for effectively blowing through the dense fins of the two radiators.
• 4-pin PWM connector for automatic RPM control and 5V ARGB for synchronized lighting with other components.

Who it is suitable for

Peerless Assassin 120 SE ARGB is a good choice if you are building a gaming or productivity machine and want serious air cooling with ARGB, without switching to liquid cooling. It is suitable for mid to high-end processors on AM4/AM5 and LGA 1700/1851 platforms, provided that your case can accommodate a dual-tower cooler. If you are aiming for super-compact ITX builds or extreme overclocking, it might be better to look for lower/more specialized solutions.

The combination of dual-tower design, high airflow, and low noise, plus ARGB and wide socket compatibility, makes this cooler a very sensible option for a stable and good-looking build.
