Air cooler Thermalright Peerless Assassin 120 SE ARGB 12 cm Black 1550 RPM
The Thermalright Peerless Assassin 120 SE ARGB 12 cm Black 1550 RPM is a compact air cooler engineered for consumer and enthusiast desktop CPUs. This cooler combines a 120 mm fan with Fluid Dynamic Bearing (FDB) for quieter operation, a maximum rotational speed of 1550 RPM and a reported maximum air pressure of 1.53 mmH2O. The unit has a slim footprint with dimensions of 110 mm (W) x 125 mm (D) x 155 mm (H) in a black finish, and is intended to fit a wide range of mainstream processor sockets.
The cooler offers a balance of cooling performance and low acoustic output through its 120 mm FDB fan and moderate maximum speed. Its compact dimensions make it suitable for systems with limited clearance while still providing directed airflow over the heatsink. ARGB lighting integration allows synchronization with supported motherboard or controller ecosystems for visual customization. Compatibility with multiple modern and legacy sockets reduces the need for alternative mounting solutions.
Install the cooler following the manufacturer’s mounting instructions for the specific CPU socket in use. Prepare the CPU surface and apply an appropriate amount of thermal paste if it is not pre-applied. Secure the heatsink to the motherboard using the included brackets and fasteners, ensuring even pressure across the CPU heatspreader. Connect the fan power cable to the CPU_FAN or designated fan header and connect the ARGB cable to a compatible lighting header or controller for illumination control. Verify fan operation and monitor temperatures after initial startup to confirm correct installation.
For reliable operation, ensure adequate case airflow and clearances around the cooler; maintain periodic dust removal from the fan and heatsink fins. When adjusting fan curves or ARGB settings, use motherboard or controller software compatible with the cooler’s connectors. Confirm support for your specific CPU socket before installation.
