Thermalright Peerless Assassin 120 Digital A-RGB Black Dual-Tower CPU Cooler

Thermalright Peerless Assassin 120 Digital A-RGB Black is a dual-tower air cooler for CPU, aimed at mid-range and high-end builds where you seek serious cooling without water. With two 120 mm fans and a wide compatible socket range, you can easily plan it for several generations of upgrades. The built-in A-RGB lighting and digital control give it a modern look without sacrificing efficiency. At up to 1850 RPM and a relatively low noise level of 25.6 dBA, you get a balance between performance and comfort.

What you get

You get a dual-tower design with two 120 x 120 x 25 mm fans, which means a larger contact area of the heatsink and better heat dissipation under load CPU. The wide RPM range of 500–1850 RPM allows you to set profiles – quiet idle and aggressive cooling under load. The maximum airflow of 177.78 CFM, combined with 2.21 mm H2O static pressure, is a strong plus for dense cooling fins and more closed cases where air needs to be “pushed” through the heatsink. The built-in 5V ARGB and 9-pin USB 2.0 connections give you easy control via software, while the standard 4-pin PWM connector provides automatic speed adjustment according to the CPU temperature.

• Dual-tower design with 2 x 120 x 120 x 25 mm fans provides greater airflow through the heatsink for more stable temperatures during long gaming or rendering sessions.
• Wide speed range from 500–1850 RPM allows for quiet operation under low load and aggressive cooling when the CPU is under full load.
• Maximum airflow of 177.78 CFM helps quickly dissipate warm air from the area around the socket, especially in cases with better overall airflow.
• Static pressure of 2.21 mm H2O is suitable for a heatsink with dense fins, where the fans need to effectively “push” air through the aluminum fins.
• Low noise level of around 25.6 dBA allows you to keep a powerful CPU cool without the system turning into a turbine during operation.
• Compatibility with multiple sockets – AM4, AM5, LGA 115x, LGA 1200, LGA 1700, LGA 1851 – means you can use it with both current and older platforms.
• 4-pin PWM for speed control, plus 5V ARGB and 9-pin USB 2.0 for lighting and digital functions give you flexible integration with the motherboard and software.

Who it is suitable for

It is suitable for gaming and work configurations where you want stable air cooling for modern CPUs on AM4/AM5 and LGA 1700/1851, without entering the world of water systems. It is also a good choice if you care about A-RGB aesthetics and a quiet profile during everyday use. If you are aiming for extreme overclocking with maximum TDP and do not have good case ventilation, it may be better to look for even more massive solutions.

The combination of dual-tower design, high airflow, and wide socket range makes this Thermalright Peerless Assassin 120 Digital A-RGB Black a very practical choice for a long-term build. You get serious cooling, flexible control, and a modern look in a well-balanced air cooler.
