The Thermalright Peerless Assassin 140 Black is an air cooling unit configured to manage high thermal loads generated by modern processors. This dual-tower heatsink utilizes six 6mm diameter copper heat pipes designed for efficient thermal transfer away from the copper base plate. Heat dissipation is achieved through a specific dual-fan arrangement, featuring one 120mm unit positioned on the exterior and one 140mm unit placed between the radiator towers. This structure facilitates comprehensive airflow across the entire fin stack.
Both installed fans operate at a controlled maximum rotational speed of 1500 RPM and incorporate S-FDB bearings for consistent operation. The cooling solution is rated to produce a maximum noise level of 25.6 dB under full load conditions. Performance specifications include a peak airflow output of 77.8 CFM and a static pressure of 2.09 mmH₂O, indicating effective performance even when faced with resistance from dense fin arrays. The unit requires 158mm of vertical clearance within the PC chassis.
The cooler is engineered for broad compatibility across current desktop platforms. Supported sockets include Intel LGA 1700, 1200, and 115X series, alongside AMD’s AM4 and AM5 interfaces. Connection requires a standard 4-pin header, providing Pulse Width Modulation (PWM) functionality for dynamic speed adjustment. The total installed dimensions measure 132mm in width and 140mm in depth, ensuring suitability for a range of desktop PC builds.
