The Peerless Assassin 140 White is a high-performance dual-tower air cooler designed for maintaining stable operating temperatures in high-thermal design power processors. The cooling structure incorporates six 6mm diameter heatpipes that run through the dual aluminum fin stacks. Thermal transfer efficiency is achieved via a C1100 pure copper, nickel-plated base plate, which maximizes contact area with the CPU integrated heat spreader. This entire assembly is rated to dissipate up to 250W of thermal load.
Heat dissipation is managed by two fans—a 120mm and a 140mm unit—both utilizing S-FDB bearings for reduced friction and extended operational lifespan. Both fans operate up to 1500 RPM and feature Pulse Width Modulation (PWM) support for automatic speed control based on thermal requirements. At maximum rotational speed, the cooler delivers 77.8 CFM of airflow while generating a static pressure of 2.09 mmH2O. The operational noise output peaks at 25.6 dB under full load conditions. The 158mm height requires consideration for case clearance, but the design provides wide compatibility across modern platforms, including current Intel LGA 1700 and AMD AM5 sockets.
