The Thermalright Peerless Assassin 140 Black (PEERLESS ASSASSIN 140 BLACK) is an elite, high-performance dual-tower CPU air cooling solution engineered to handle intense thermal loads generated by next-generation multi-core processors. Featuring a stealthy, fully blacked-out structural aesthetic, this heavyweight thermal system delivers premium heat extraction for high-end gaming configurations and workstation computing without disrupting clean hardware design themes.
The physical architecture of the thermal assembly leverages an asymmetrical split dual-tower fin layout coupled with a precision-machined, micro-engraved C1100 pure copper nickel-plated cold plate. Operating alongside six robust 6mm anti-gravity heatpipes and a mismatched high-pressure 120mm and 140mm fan array, it generates massive volumetric airflow velocity through dense core cooling channels to sustain a commanding heat dissipation capacity under continuous computation surges.
Key Features & Specifications
Advanced Dual-Tower Heat Dissipation: Designed with a symmetrical dual-tower aluminum fin array that expands the surface cooling field to accelerate thermal conduction away from the core base.
AGHP Anti-Gravity Heatpipe Technology: Uses six premium 6mm copper heatpipes engineered with special internal capillary structures to guarantee unrestricted heat transfer efficiency in both horizontal and vertical case mounting configurations.
Asymmetrical Mixed Dual-Fan Setup: Employs a specific combination of a high-pressure 120mm intake fan and a larger 140mm mid-tower fan to optimize constant positive airflow velocity while reducing internal physical turbulence.
Fluid Dynamic Bearing Engineering: Both fans utilize integrated S-FDB bearing architectures to significantly reduce operational friction, keeping peak noise outputs low while expanding the mechanical life of the rotation assembly.
Robust SS2 Multi-Socket Support: Includes heavy-duty structural all-metal fasteners that provide balanced mounting seating pressure and native, toolless compatibility across current AMD AM5/AM4 and Intel LGA 1851/1700 platforms.
The Computer Guy Charmhaven Advantage
In-Store Advice: Our local workshop team will check your specific desktop layout to confirm that your chassis internal width can easily clear the 158mm physical tower height without coming into contact with your enclosure’s side panels.
Local Support & Advice: Visit our Charmhaven workbench on the Central Coast for practical, face-to-face tips on shifting fan mounting clips to accommodate tall high-profile RAM modules, selecting premium thermal interface pastes, and configuring custom UEFI BIOS PWM fan acoustics.

Important Product Information
Clearance & Form Factor Restrictions: This large cooling system features a total installation height profile of 158mm, and system configurations utilising tall enthusiast memory kits may require clipping the front 120mm fan slightly higher on the tower assembly.
Power & PWM Routing: The dual cooling fans require standard 4-pin PWM connections, necessitating the deployment of the provided Y-splitter connector to route power smoothly through a single dedicated motherboard CPU_FAN utility header.
