Noctua NF-A9 PWM, Premium Quiet Fan, 4-Pin (92mm, Brown)

- The NF-A9 is a 92 mm fan that pumps out high airflow while staying nice and quiet - Thanks to PWM control, the fan only turns on and speeds up when it needs to - The anti-vibration pads and low noise adapter minimise noise for a quieter setup- Its AAO frame and stepped inlet blades are strong and durable- The Zero RPM mode turns the fan blades off during light loads for silent operation- Its hydrodynamic bearing's got a long lifespan, giving you years of quiet cooling - Manufacturers part numbers: NF-A9 PWM|678258
