## Summary description

Thermalright Peerless Assassin 140 SE is a dual-tower air CPU cooler designed for effective heat dissipation in desktop systems. It supports mounting of 140 mm fans and uses a multi-heatpipe tower design to transfer heat away from the CPU. Suited for gaming rigs, workstations and overclocked systems, it provides reliable cooling performance and is compatible with mainstream sockets.

## Long description

Thermalright Peerless Assassin 140 SE is a dual-tower air cooler engineered for efficient heat removal in desktop PCs. The cooler employs multiple heat pipes and two fin stacks to move thermal energy from the CPU contact plate to a larger dissipation area. It supports installation of 140 mm fans to provide higher airflow at lower RPM, and its design targets gaming systems, workstations and overclocked rigs that require sustained cooling performance while maintaining reasonable acoustic levels.
Advantages
The dual-tower layout increases fin surface area for improved heat dissipation compared with single-tower designs. Compatibility with 140 mm fans allows effective airflow with lower rotational speed, reducing noise for equivalent cooling capacity. The multi-heatpipe construction ensures direct and rapid transfer of heat from the CPU to the fins. The cooler is designed for broad socket compatibility with common desktop platforms and includes mounting hardware for secure installation.
Suitable for
High-performance gaming desktops that run extended gaming sessions
Workstations performing CPU-intensive tasks such as rendering or data processing
Overclocked systems requiring enhanced cooling headroom
Systems where balance between cooling performance and acoustic level is important
Key specifications
Dual-tower heatsink architecture with two fin stacks
Support for 140 mm fan mounting (fan(s) not necessarily included)
Multiple heat pipes for direct heat transfer from the CPU contact plate
Aluminium fin construction for efficient thermal conduction
Solid base plate for stable contact with CPU heatspreader
Designed for compatibility with mainstream desktop CPU sockets
How to use
Install the Thermalright Peerless Assassin 140 SE on a compatible motherboard following the included mounting instructions. Begin by preparing the CPU surface and applying a thin, even layer of thermal paste. Secure the cooler's mounting bracket to the motherboard using the supplied hardware, align the cooler base over the CPU, and fasten the retention mechanism evenly to ensure consistent contact. Attach 140 mm fan(s) to the fin stacks in the intended airflow direction, connect fan power cables to the motherboard fan headers, and verify BIOS/firmware fan control settings for optimal thermal and acoustic balance.
Usage recommendations
For best results, pair the cooler with high-quality 140 mm fans and ensure adequate case airflow. Check clearance for RAM modules and tall memory heatsinks before installation, and confirm that the cooler fits inside your case with respect to motherboard and chassis dimensions.
