Air cooler Thermalright Peerless Assassin 120 ARGB
The Thermalright Peerless Assassin 120 ARGB is a compact white air cooler designed for effective CPU heat dissipation in desktop systems. It integrates a 120 mm fan with a maximum rotational speed of 1550 RPM and Fluid Dynamic Bearing (FDB) technology to balance airflow performance with reduced operational noise. With overall dimensions of 135 mm (W) x 125 mm (D) x 157 mm (H) and a weight of 0.75 kg, the cooler fits many mid-tower and compact cases while adding ARGB lighting for system aesthetics.
The Peerless Assassin 120 ARGB delivers a combination of reliable cooling performance and quiet operation thanks to its 120 mm fan and FDB bearing. Its modest height and compact footprint make it suitable for systems where space is limited. The white finish provides a neutral look that complements a variety of build themes, and integrated ARGB lighting offers visual customization without compromising cooling function.
Prepare the motherboard and CPU area by removing any previous cooler and cleaning the CPU heatspreader. Install the appropriate mounting brackets for your processor socket following the included instructions, apply an appropriate amount of thermal paste to the CPU, then position the Peerless Assassin 120 ARGB onto the mounting points and secure it evenly. Connect the fan power cable to a CPU fan header and the ARGB cable to a compatible RGB header or controller. After installation, verify fan operation and ARGB lighting in the system BIOS or software and monitor temperatures under load.
Ensure case airflow is not obstructed and that RAM or motherboard components do not interfere with the cooler. Use the manufacturer-recommended mounting orientation and verify compatibility with tall memory modules. For optimal results, check thermal paste application and confirm fan header settings to allow the cooler to vary speed according to CPU temperature.
