## Long description

Thermalright Peerless Assassin 140 Digital is a CPU heatsink/radiator with a configurable 120/140 mm fan that spins up to 1850 RPM. The unit has sealed precision FDB bearings and a white finish. With dimensions of 160 × 140 × 165 mm and a maximum air pressure of 2.1 mmH2O, it is designed to provide effective processor cooling in desktop systems and supports modern CPU sockets including AM5, AM4, LGA1700 and LGA2066.
Advantages
The heatsink combines a compact tower design with support for a 120/140 mm fan, delivering balanced airflow and static pressure for CPU cooling. Sealed precision FDB bearings reduce noise and increase fan lifespan while PWM control allows automatic speed adjustment based on temperature. The white finish fits a variety of build aesthetics without affecting thermal performance.
Suitable for
Air-cooled desktop PC builds requiring effective CPU heat dissipation
Systems using Socket AM5, Socket AM4, LGA1700 or LGA2066 processors
Quiet or semi-passive cooling setups where low fan noise is important

How to use
Mount the heatsink onto the motherboard following the manufacturer’s installation instructions for the target socket (AM5, AM4, LGA1700 or LGA2066). Apply an appropriate amount of thermal compound to the CPU heat spreader, align the base of the heatsink and secure it with the provided brackets and screws. Connect the fan to the CPU fan header or a PWM-controlled header on the motherboard to enable automatic speed regulation.
Usage recommendations
For best results, ensure good case airflow by arranging intake and exhaust fans to create a clear flow path across the heatsink. Verify compatibility with your case internal dimensions and memory modules, and reapply thermal compound after removing the heatsink for maintenance.
