Corsair RS140 140mm PWM - case fan, white

DIRECT-TO-MOTHERBOARD CONNECTION
Skip the fan hubs and excessive cables – daisy-chain your RS Series fans in sequence and control them all through just a single 4-pin PWM connector on your motherboard.

AIRFLOW AND STATIC PRESSURE
A better fan relies on several key features, each improving how it handles air pressure and airflow as a radiator or case fan. RS fans were engineered to excel at both.

BLADE SHAPE
Optimized angle of attack, airfoil shape, and edge curvature ensure maximum airflow efficiency.

FAN HOUSING
The fan housing was designed to support the largest possible blade radius within its size limit.

CORSAIR AIRGUIDE
Stator vanes are angled to focus the exhaust airflow cone and improve the coverage of radiator fins and heat dissipation.

EVERY SOURCE OF NOISE ADDRESSED
MAGNETIC DOME BEARING
This improved bearing minimizes friction and mechanical noise, achieving a balance between high airflow performance and low acoustic footprint. On top of that, the reduced friction means greater longevity for your fan.

STRENGTH IN NUMBERS
PROVEN COOLING PERFORMANCE
RS fans have undergone months of extensive testing to guarantee exceptional performance at the full range of PWM fan speeds set with their direct-to-motherboard connection.

ZERO RPM MODE
PWM control lets you precisely set fan speeds so your fans only spin as fast as they need to, resulting in less fan noise overall, while support for Zero RPM means they can stop spinning completely at low loads to eliminate fan noise.
