## Summary description

Thermalright Peerless Assassin 140 SE ARGB is a CPU air cooler featuring a dual-tower heatsink design and ARGB lighting. Designed for compatibility with 140mm fans, it provides improved heat dissipation for desktop processors. Suitable for gaming rigs and workstations, it helps maintain lower CPU temperatures under load and supports standard mounting for common sockets.

## Long description

The Thermalright Peerless Assassin 140 SE ARGB is a dual-tower CPU air cooler designed for desktop processors. It features a twin-tower heatsink layout optimized for 140mm fan installation and includes ARGB lighting for visual integration with modern PC builds. The cooler is engineered to improve heat dissipation compared with single-tower designs while maintaining compatibility with standard motherboard sockets and typical RAM heights.
Advantages
The dual-tower construction increases available surface area for heat transfer, allowing more efficient dissipation from the CPU heat pipes into the fins. Support for 140mm fans provides higher airflow at lower fan speeds compared to smaller fans, which can reduce noise under load. Integrated ARGB lighting offers addressable illumination that can be synced with motherboard control software. The mounting system is designed to deliver secure contact with the CPU heatspreader and to support a range of mainstream processor sockets.
Suitable for
 Gaming desktop builds requiring improved CPU cooling
 Workstations running sustained CPU-intensive tasks
 PC cases with clearance for dual-tower coolers and 140mm fans
 Systems where ARGB lighting synchronization is desired
Key specifications
 Cooling architecture: dual-tower heatsink with multiple heat pipes
 Fan support: compatible with 140mm fans for intake and exhaust
 Lighting: addressable RGB (ARGB) integrated on the cooler or included fan(s)
 Material: aluminium fins with copper heat pipes and base for thermal conduction
 Compatibility: designed for mainstream desktop CPU socket types (tower cooler form factor)
 Noise and airflow: designed to balance airflow and acoustic performance with larger fan diameters
How to use
Install the cooler following the manufacturer’s mounting instructions appropriate for your CPU socket. Prepare the CPU by cleaning the heatspreader surface and apply a suitable amount of thermal paste before seating the cooler base. Mount the towers and fans so that airflow direction aligns with your case ventilation layout, typically front-to-back or bottom-to-top. Connect the fan power cables to the motherboard fan headers and the ARGB cable to a compatible ARGB header or controller, and verify secure mechanical fastening to avoid contact with RAM modules or other components.
Usage recommendations
Ensure your case has sufficient clearance for a dual-tower cooler and 140mm fans; check RAM height and PCIe slot space to prevent interference. Use motherboard software or an ARGB controller to manage lighting effects. For optimal thermal performance, maintain regular dust cleaning of fins and fans and consider configuring PWM fan curves in firmware or software for temperature-responsive cooling.
