Noctua Ultra Silent 140mm Fan NF-P14 FLX (Brown)

The Noctua NF-P14 FLX follows in the footsteps of the successful NF-P12, the NF-P14 is a highly optimised, premium quality 140mm fan with Vortex-Control Notches for superb quietness and outstanding aerodynamic efficiency. Metal reinforcements, SCD2 technology and Noctua premium grade SSO-Bearing guarantee exceptional running smoothness and excellent long-term stability. Using the same hole-spacing as common 120mm fans and achieving a superior airflow/noise ratio, the NF-P14 is ideal for upgrading 120mm CPU or case fans. At an impeller diameter of almost 140mm, it is critical to avoid unbalance due to the bigger rotating masses. In order to guarantee the highest possible degree of manufacturing precision, minimum tolerance and excellent long-term stability, the NF-P14 employs high precision CNC milled brass parts to reinforce the motor hub as well as a bearing shell made entirely from brass. Using a round frame with the same hole-spacing as common 120mm fans and producing more airflow due to its larger diameter, the NF-P14 is a perfect upgrade for 120mm CPU or case fans. Thanks to the supplied adaptors, the NF-P14 also fits common 140mm mounting holes. Providing 1200, 900 and 750 rpm speed settings via the supplied Low-Noise and Ultra-Low-Noise Adapters, the NF-P14 FLX (Flexibility) can be fine-tuned for superior airflow or maximum quietness. The latest version of Noctua advanced SCD drive system ensures superb running smoothness by eliminating torque variations and switching noises.
