Corsair RS140

Direct connection to the motherboard
Bypass the fan hubs and excessive cables - connect your RS series fans in series and control them all from a single 4-pin PWM connector on your motherboard.

Airflow and static pressure
A better fan is based on several key features that each improve how it handles air pressure and airflow as a radiator or case fan. RS fans are designed to excel in both areas.

Blade design
Optimised angle of attack, airflow shape and edge curvature ensure maximum airflow efficiency.

Fan housing
The fan housing has been designed to support the largest possible blade diameter within its size limit.

Corsair Airguide
Stator fins are angled to focus the airflow cone and improve radiator fin coverage and heat dissipation.

Each noise source addressed
Magnetic bearing
This improved bearing minimises friction and mechanical noise, achieving a balance between high airflow performance and low acoustic footprint. In addition, the reduced friction means a longer life for your fan.

Strength in numbers
Proven cooling performance
RS fans have undergone months of extensive testing to ensure exceptional performance across the full range of PWM fan speeds, which are set via their direct connection to the motherboard.

Zero RPM mode
PWM control allows you to precisely set fan speeds so that your fans only run as fast as they need to, resulting in less overall fan noise. Support for Zero RPM mode means they can stop completely at low loads to eliminate fan noise.
