Corsair RS 140 PWM Fan, Magnetic Dome bearing, 140mm, Black

The CORSAIR RS140 is a 140mm cooling unit intended for standard computer case integration. It operates using a 4-pin Pulse-Width Modulation (PWM) connector, allowing the system to modulate the rotational speed precisely across a wide range. The operational speed spans from a minimum of 330 RPM up to a maximum of 1700 RPM, balancing high-performance cooling potential with lower acoustic requirements.

At maximum speed, the fan is rated to deliver an airflow of 95.5 CFM and generate a static pressure of 3.46 mmH2O. Acoustic management is optimized through its minimum speed setting, which results in a low operational noise level of 10 dB, rising to 36 dB at full rotational capacity. Durability is addressed through the implementation of a Magnetic Dome bearing, contributing to the unit’s rated Mean Time Between Failures (MTBF) of 100,000 hours.

The unit features support for Zero RPM mode, enabling the fan to halt rotation entirely when system temperatures are low enough, effectively eliminating acoustic output during minimal load conditions. The physical dimensions of the fan are 140 mm by 140 mm with a 25 mm depth, making it compatible with standard 140mm mounting points in PC chassis.
