Overview

Optimized 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.
Zero RPM Mode
This feature allows the fan to stop spinning under low and moderate loads, providing total silence for those who prioritize a distraction-free environment.
Magnetic Dome Bearings
Magnetic Dome bearings in the RS II series fans minimize noise and reduce friction for greater longevity.
High-Airflow Design
RS120 II fans provide powerful airflow and can move a lot of air, measuring up to 73 CFM at maximum fan speed of 2,100rpm.
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.
More Airflow than a 30mm Fan
The engineering behind the RS II fan allows them to move more air than a thicker 30mm fan, making them highly effective with wider compatibility.
Adjustable PWM Fan Speed
Customize your fan speed using motherboard software for a truly dialed-in cooling setup.
Flexible Cooling Power
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.
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.
Easy Motherboard Fan Control
Daisy-chained fans can be controlled as a single group using motherboard software so there’s no complicated ecosystems or fan controllers required.

Well worth the cost! - I use this as an exhaust fan in my build and this thing is a MONSTER. I have a lot of intakes as this is the ONLY exhaust, and it has no problems pushing that hot air out. Great fan for its price point. Corsair is the goat.
