CPU cooler Thermalright Peerless Assassin 120 Digital White Dual-Tower CPU Cooler

Thermalright Peerless Assassin 120 Digital White is a dual-tower air cooler for CPU, aimed at powerful gaming and workstation configurations, where you seek serious cooling without switching to water. The white design and two 120 mm fans make it suitable for builds centered around a white case. Support for a wide range of sockets – from AM4/AM5 to LGA 1200/1700/1851 – gives you the freedom to use it with both current and older platforms. With a maximum rotation speed of up to 1850 RPM and low noise around 25.6 dBA, you get a combination of performance and comfort.

What you get

The two included 120 mm fans in a push-pull configuration provide strong airflow – up to 177.78 CFM, which helps maintain stable temperatures during long gaming or rendering sessions. The maximum static pressure of 2.21 mm H2O means that air passes effectively through the dense cooling fins – important in a dual-tower design. The speed range of 500–1850 RPM allows you to set a profile – quieter for everyday work and more aggressive under load. The 4-pin connector provides PWM control through the motherboard, while the additional 9-pin USB 2.0 allows for digital functions and monitoring, if your motherboard and software support it. This way, you combine serious cooling with fine-tuning of noise and behavior.

• Dual-tower air cooler with 2 x 120 x 120 x 25 mm fans for larger heat exchange area and more efficient heat dissipation.
• Wide compatibility with CPU sockets – AM4, AM5, LGA 115x, LGA 1200, LGA 1700, LGA 1851, making it a flexible choice for new and upgrade builds.
• Speed range 500–1850 RPM, allowing a balance between quiet mode at idle and aggressive cooling under maximum load.
• Maximum airflow up to 177.78 CFM, suitable for cooling powerful CPUs and for long gaming or productivity sessions.
• Static pressure 2.21 mm H2O, which helps air pass effectively through the dense fins of the radiator.
• Low noise level around 25.6 dBA, so the system remains relatively quiet even at higher speeds.
• Combination of 4-pin PWM and 9-pin USB 2.0 connectors for precise fan control and additional digital features.

Who it is suitable for

This cooler is a good choice if you are building a mid-range to high-end gaming or workstation machine and want reliable air cooling with the potential for higher CPU frequencies. It is also suitable if you often work under long load – streaming, rendering, compiling – and want to keep temperatures under control without the system sounding like a vacuum cleaner. If you are aiming for a super quiet, entirely low-profile build in a small case, this dual-tower form factor might be a bit large for you.

The strongest aspect of the Thermalright Peerless Assassin 120 Digital White is the combination of powerful airflow, relatively low noise, and wide compatibility with modern sockets, making it a stable foundation for serious gaming or creative builds.
