## Summary description

Suitable for everyday use, gaming rigs and workstation builds where effective air cooling and compact dual-tower performance are required.

## Long description

Thermalright Peerless Assassin 120 SE Black is a 120mm-class CPU air cooler with a dual-tower heatsink design finished in black. The cooler is built for mainstream desktop processors and accepts 120mm fans to create airflow through two stacked fin arrays. Multiple heat pipes connect the base to the fin stacks to transfer heat away from the CPU, delivering improved dissipation compared with single-tower designs while keeping a compact footprint for many tower-style PC cases.
Advantages
The dual-tower layout increases fin surface area for better heat exchange while remaining compatible with standard 120mm fans. The black finish provides a neutral appearance that integrates with a wide range of builds. Multiple heat pipes and a direct-contact base improve thermal transfer from the processor to the fins. The cooler's dimensions and mounting system are intended to provide compatibility with mainstream CPU sockets and typical memory module heights.
Suitable for
Everyday desktop systems requiring reliable air cooling
Gaming PCs where sustained CPU cooling is needed under load
Workstations performing productivity tasks that generate moderate heat
Upgrades from stock coolers to achieve lower temperatures and quieter operation
Key specifications
Form factor: 120mm-class dual-tower air cooler
Fan support: compatible with standard 120mm fans (single or dual configuration)
Cooling structure: stacked aluminium fin arrays with multiple heat pipes
Finish: black-coated heatsink surfaces
Compatibility: designed for mainstream desktop CPU sockets and typical memory clearance
How to use
Install the cooler according to the motherboard and case orientation so that airflow aligns with the case ventilation. Mount a 120mm fan or two onto the fin stacks using the supplied clips or fan screws, ensuring the fan direction pushes air through the fins toward an exhaust. Apply a thin, even layer of thermal paste to the CPU heatspreader, position the cooler’s base onto the CPU, and fasten the mounting brackets following the manufacturer's torque guidance to ensure stable contact without overtightening. Connect the fan(s) to the appropriate CPU fan header(s) on the motherboard and configure fan curves in BIOS or software for desired noise and cooling balance.
Usage recommendations
For optimal performance, use at least one high-quality 120mm fan with a balanced airflow/noise profile; consider a push–pull configuration with two fans if case space and clearance allow. Verify memory and RAM cooler clearance before installation, and ensure case airflow supports intake and exhaust to maximize the cooler’s effectiveness. Periodically clean dust from the fins and fans to maintain thermal performance.
