Product information

Description

The Thermalright Peerless Assassin 120 SE is a 120 mm black processor heatsink designed to provide effective CPU cooling. It uses a dual-tower heatsink arrangement combined with a 120 mm fan to improve heat dissipation while remaining compact enough for many builds. The cooler supports a wide range of Intel and AMD sockets, including LGA 115x/1200/1700 and AM4/AM5.

The dual-tower heatsink and effective fan pairing provide reliable heat transfer without excessive height, and the all-black finish fits a variety of system aesthetics.

How to use

Install the heatsink following the manufacturer’s mounting instructions for the specific CPU socket. Apply a thin, even layer of thermal paste on the CPU heatspreader, secure the cooler to the motherboard with the included mounting hardware, and connect the fan to the CPU_FAN or system fan header. Ensure there is adequate clearance in the case for the cooler dimensions and that airflow inside the case is not obstructed.

Usage recommendations

For optimal cooling, position case intake and exhaust fans to create a directed airflow path across the Peerless Assassin 120 SE. Check compatibility with memory modules and VRM heatsinks to ensure the cooler does not interfere with adjacent components.
