This is for 3x Corsair RS120 fans, swapped out from a brand-new Corsair case.

The Corsair RS120 120mm PWM Fans Triple Pack gets your PC cooling setup off on the right foot with three efficient and reliable fans. Daisy-chained 4-pin PWM connectors let you link multiple fans together and control them all through just a single 4-pin PWM header on your motherboard. Enjoy fan speeds up to 2,100 RPM, with the static pressure to be great for radiator use as well. Corsair AirGuide Technology with anti-vortex vanes directs airflow for concentrated, powerful cooling. Magnetic Dome bearings ensure quieter operation and increased longevity, while Zero RPM mode offers silent operation at low loads.

• Streamlined Fan Connections: Daisy-chain multiple fans together and control them all through just a single 4-pin PWM connector.
