Product information

Description

The Thermalright Peerless Assassin 120 is an air cooler engineered for efficient CPU heat dissipation in desktop systems. It includes a 120 mm fan with a maximum rotational speed of 1550 RPM and a fluid dynamic bearing designed to reduce noise while maintaining steady airflow. The cooler is finished in black and has a compact footprint suitable for many mid-tower and smaller cases, providing a balance between cooling performance and space requirements.

Advantages

The Peerless Assassin 120 combines a low-noise 120 mm fan and an aerodynamic impeller to deliver focused airflow with a measured maximum static pressure of 1.53 mmH2O. Its compact dimensions allow installation in systems with limited clearance while still offering effective heat transfer from the CPU. The fluid dynamic bearing increases fan lifespan and reduces mechanical noise, and the overall design keeps weight low at approximately 0.75 kg.

Suitable for

Everyday desktop computers requiring reliable CPU cooling
Compact or mid-tower gaming builds with limited cooler clearance
Workstations running sustained CPU workloads at stock or mildly overclocked settings
System builders who prefer a black, low-profile cooler aesthetic

How to use

Install the Thermalright Peerless Assassin 120 according to the motherboard and case clearance. Mount the cooler on the CPU using the supplied mounting hardware compatible with the listed sockets and ensure even contact with a thin, uniform layer of thermal paste. Connect the fan to the motherboard fan header or a fan controller and verify the fan spins correctly during system startup. Monitor CPU temperatures under load after installation and, if necessary, adjust fan curves in BIOS or fan-control software to achieve the desired balance between cooling and noise.

Usage recommendations

Ensure sufficient case airflow by using at least one intake and one exhaust fan to complement the Peerless Assassin 120. For systems with high ambient temperatures or sustained heavy CPU loads, verify that the cooler has adequate clearance from RAM modules and GPU to maintain optimal airflow paths.
