RS140 II 140mm PWM Fan in Black from CORSAIR

RS140 II 140mm PWM Fan Hero Image

OPTIMISED FOR QUIET OPERATION The second-generation CORSAIR RS140 II PWM fan has been revamped to deliver class-leading acoustics both at lower RPMs and at maximum power for an overall quieter experience while providing excellent cooling performance. Features such as Zero RPM Mode and Magnetic Dome bearings ensure reliable operation that is very quiet while providing powerful and effective cooling. RS II fans can be daisy-chained together for an easy setup with fewer cables, and just a single 4-pin PWM motherboard header is needed to control fan speeds. AirGuide technology with anti-vortex vanes direct airflow for concentrated, powerful cooling.

Optimised for Quiet Computing The RS II series has been redesigned to offer improved airflow efficiency at lower fan speeds, moving more air than its predecessor at moderate fan speeds for a quieter cooling experience with excellent performance.

High-Airflow Design RS140 II fans provide powerful airflow and can move a lot of air, measuring up to 96 CFM at maximum fan speed of 1,700rpm.

AirGuide Technology Angled anti-vortex stator vanes on each fan assist in focusing airflow to improve cooling performance while allowing for targeted cooling of hot components and better static pressure when pushing air through a dense radiator.

Adjustable PWM Fan Speed Customise your fan speed using motherboard software for a truly dialed-in cooling setup. RS II fans excel as both case and radiator fans, offering powerful airflow and excellent static pressure to improve both air and liquid cooling setups.

Close up image of daisy chain cable

Daisy-Chain Connectivity RS II fans can be daisy-chained together with just one cable going to the motherboard’s 4-pin PWM connector for a quick and hassle-free installation process. Daisy-chained fans can be controlled as a single group using motherboard software so there’s no complicated ecosystems or fan controllers required.
