> 3 dayQuietest fans Ive ever owned. My only complaint is the rubber screws they provided to install the fans in the case broke when I tried to install them. The amount of force needed to push them through was unexpectedly high. I ended up just removing then and using some extra fan screws I already had.

Greater than one weekIt works, its quiet and I love them. The color is ugly, but I didnt buy it for looks. With the same RPMs as my stock fans on the Thermaltake cooler, you can definitely hear the difference and Im getting the same cooling.

> 3 dayEdit: I decided to give the low noise adapter a shot before calling it quits. With the low noise adapter attached, I dont get a drone at the the very lowest speeds. But silence at the cost of such little airflow, and almost $30 does not an acceptable product make. I will still be removing and returning this fan when I have time a little later in the week.

> 3 dayReally good fan. I cant hear them at low RPM, but theyre relatively loud at high RPM. Theyre basically always running at low RPM so this is fine for me (using PWM to control them).

> 3 daySo quiet I almost took my computer apart again after installing it to make sure it was on. Installation was a breeze ;).

> 3 dayGreat fan. Great airflow. Low noise. 4-pin connector allows variable speed.
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 the renowned quiet cooling performance of the award-winning NF-P14. The PWM version sports Noctua’s custom designed NE-FD1 IC for fully automatic speed control via 4-pin fan headers and comes with a Low-Noise-Adaptor to reduce the maximum speed during PWM control from 1500rpm to 1200rpm. Its performance-oriented 1500rpm top speed and comprehensive speed control options make the NF-A14 PWM an elite choice for users who strive to strike a perfect balance between excellent cooling capacity and superb quietness of operation, be it on watercooling radiators, on heatsinks or in case ventilation.
Square 140mm frame
The NF-A14"s square 140mm frame with 140mm mounting holes (124.5mm spacing) makes it a premium grade replacement for common 140mm case fans and perfect for use on 140mm water cooling radiators, where its square shape will ensure full coverage and best pressure performance.

|---|---|---|---|
Flow Acceleration ChannelsThe NF-A14 impeller features suction side Flow Acceleration Channels. By speeding up the airflow at the crucial outer blade regions, this measure reduces suction side flow separation and thus leads to better efficiency and lower vortex noise. |
SSO2 BearingThe NF-A14 features the further optimised second generation of Noctua"s renowned, time-tested SSO bearing. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability. |
Integrated anti-vibration padsIntegrated anti-vibration pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard screws and other mounting systems. |
Scope of delivery
|
AAO frame
Noctua"s AAO (Advanced Acoustic Optimisation) frames feature integrated anti-vibration pads as well as Noctua"s proprietary Stepped Inlet Design and Inner Surface Microstructures, both of which further refine the fan"s performance/noise efficiency.
