The Noctua Chromax Inlet Side Spacers for Noctua 140mm Fans is an inlet spacer kit for the Noctua 140mm fans. The NF-A14 is a premium quality quiet 140mm fan with a square frame that complies with Noctua's AAO (Advanced Acoustic Optimisation) standard.

Just cut the original fan’s cable, fix it to the adaptor using the supplied cable connectors and you can plug the NF-F12 5V to proprietary fan headers!Designed for pressure demanding applications such as heatsinks and radiators, the Focused Flow frame features eleven stator guide vanes that straighten, channel and focus the airflow, which allows the NF-F12 to rival the performance of conventional fans running at much faster speeds. Both cables are fully sleeved and a 4-pin y-cable allows to connect a second NF-F12 fan to the same PWM fan header for automatic control. The NF-A4x10 comes with an adaptor from 3-pin Molex to the 2-pin connectors used on many graphics cards or network and storage devices. It is not possible for us to draw any conclusions about you, and any data collected as a result will never be passed on to third parties.

Custom designed for the new Focused Flow™ frame and to work in tandem with the eleven stator guide vanes, the NF-F12's seven blade Heptaperf™ impeller has been carefully optimised to achieve a perfect balance between power and quietness. This means that the NF-A12x25 is a true jack-of-all-trades with excellent performance in both static pressure demanding and airflow demanding applications. g. the NF-S12A 120mm fan at 1200rpm is quieter than the NF-F12 120mm fan at 1200rpm), so always refer to our dB(A) specifications rather than to RPM speeds only.The new redux edition NF-R8 80mm fans offer quiet operation, superior airflow and feature an industry grade SSO bearing, an MTBF rating of over 150,000 hours and a 6 year Noctua warranty.

The Noctua NF-A4x10 5V PWM 40mm Fan features an advanced aerodynamic design with flow acceleration channels and an AAO frame, reduced motor hub, integrated anti-vibration pads, custom PWM IC with SCD, SSO2 bearing, and an OmniJoin adapter set.

Accessories: Redux and industrialPPC line fans come with mounting screws only whereas the standard-line fans come with a rich bundle of accessories (different cables, adaptors, anti-vibration mounts, etc. Featuring Noctua’s AAO (Advanced Acoustic Optimisation) frame as well as sophisticated aerodynamic design measures such as Flow Acceleration Channels, the NF-A8 further improves the renowned quiet cooling performance of the award-winning NF-R8.
