Noctua NF-A14 140mm ULN 800RPM Fan

The NF-A14 is a premium quality quiet 140mm fan with a square frame that complies with Noctua’s AAO (Advanced Acoustic Optimisation) standard. Its square shape and 140mm mounting holes (124.5mm spacing) make it ideal for use on watercooling radiators or as an upgrade for 140mm case fans. Featuring sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A14 further improves on Noctua's renowned quiet cooling performance. The ULN version provides super slow 800 or 650rpm speed settings for ultra low noise applications and highly noise sensitive users who demand near silent operation. Its superb running smoothness, reference class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands.
