Ventola Corsair RS140 14 cm nero 330–1700 U/min 0,11–3,46 mmH2O

The Corsair RS140 is a 140 mm black case fan designed for direct-to-motherboard connection via a single 4-pin PWM header. It operates between 330 and 1700 RPM and delivers air pressure from 0.11 to 3.46 mmH2O, offering a balance of airflow and static pressure suitable for use on radiators or as a chassis fan.

Advantages

RS140 fans integrate features that improve airflow efficiency and reduce noise: optimized blade geometry for effective air movement, a fan housing that allows a large blade radius within the 140 mm form factor, and Corsair AirGuide stator vanes that focus exhaust airflow to better cover radiator fins. A magnetic dome bearing reduces friction and mechanical noise while extending fan lifespan. PWM control with Zero RPM support enables precise speed regulation and minimal acoustic output at low loads.

Suitable for

• PC cases requiring a 140 mm fan
• Radiator cooling in liquid-cooled systems
• Airflow or static-pressure-focused cooling tasks

How to use

Connect the RS140 to a motherboard 4-pin PWM header and configure fan curves in BIOS or your motherboard software to match desired cooling and noise levels. When used on radiators, orient the fan so the Corsair AirGuide vanes align with airflow across the radiator fins. For multiple RS Series fans, daisy-chain them in sequence to the same PWM header where supported by your motherboard.

Recommendations

Set a PWM profile that allows Zero RPM at low system loads to eliminate unnecessary noise, and choose higher fan speeds under sustained CPU/GPU load or during intensive tasks to maximize cooling performance.
