Ventola Corsair RS120 12 cm nera 420-2100 RPM 3 pezzi

The Corsair RS120 is a 120 mm case fan sold in a pack of three and designed for direct-to-motherboard connection via a single 4-pin PWM header. It covers a wide speed range (420–2100 RPM) and a maximum static pressure of 4.15 mmH2O, combining a compact 120 mm form factor with an emphasis on airflow efficiency, radiator coverage and quiet operation.

Advantages

RS120 fans feature an optimized blade shape, enlarged usable blade radius within the fan housing and Corsair AirGuide stator vanes to concentrate exhaust airflow over radiator fins. A magnetic dome bearing reduces friction and mechanical noise while extending service life. PWM control and Zero RPM support allow precise speed regulation and the option to stop the fans at low loads for reduced noise. The fans are designed and tested for consistent performance across the full PWM speed range when daisy-chained directly to the motherboard.

Suitable for

• Case ventilation in mid-tower and compact builds
• Radiator cooling in liquid CPU/GPU loops
• Systems requiring low acoustic impact with variable fan speeds

Key specifications

• Type: Fan
• Diameter: 120 mm
• Pack quantity: 3 pieces
• Speed range: 420–2100 RPM (PWM)
• Maximum static pressure: 4.15 mmH2O
• Connector: 4-pin PWM (direct-to-motherboard)
• Colour: Black

How to use

Mount the RS120 fans in the case or on a radiator using the four standard mounting points. Connect the fans in sequence (daisy-chain) and plug the final 4-pin connector into a motherboard PWM fan header to enable unified speed control. Configure fan curves or enable Zero RPM mode in your motherboard BIOS or fan-control software to adjust performance and noise according to system load.

Recommendations

For radiator installations, place the fans so the focused exhaust cone produced by the AirGuide stator vanes passes directly over radiator fins. When using multiple fans, test different intake/exhaust arrangements and set PWM curves to balance cooling and acoustics. Avoid obstructing fan airflow and ensure the 4-pin header supports the combined current draw of chained fans.
