How to use
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.
Usage recommendations
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.
