Noctua NF-A14 PWM, Premium Quiet Fan, 4-Pin (140mm, Brown)

Product Information

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. I ran a 7950 right above a PSU with the reference GTX 480 above it, and the 480 was actually running cooler (then again, my card hasn't passed 80C under load so I'm special). While its fibre-glass reinforced polyamide construction and certified water and dust protection make the NF-A14 industrialPPC suitable for operation in challenging environments, the renowned SSO2 bearing technology guarantees an MTBF of over 150,000hrs. Thanks to the outstanding aerodynamic efficiency of the NF-A14 design and the use of a novel three-phase motor, the industrialPPC version provides superior airflow and pressure capacity while keeping noise levels and power consumption moderate as against comparable high-speed fans. Swap is a silent 140 mm premium fan with round AAO (Advanced Acoustic Optimization) frame and 140 mm mounting holes (105 mm hole spacing).

The NF-A14 features the further optimised second generation of Noctua's renowned, time-tested SSO bearing. With the tips of the fan blades ploughing through the boundary layer created by the Inner Surface Microstructures, flow separation from the suction side of the blades is significantly suppressed, which results in reduced blade passing noise and improved airflow and pressure efficiency. The NF-A14 is a premium quality quiet 140mm fan with a square frame that complies with Noctua's AAO (Advanced Acoustic Optimisation) standard.

For even greater cooling performance on current high-end CPU coolers, the width has been extended to 150 mm and complemented by advanced aerodynamic design measures such as Flow Acceleration Channels, which again improve the silent performance. C. Sound measured in front of the case was 56,3 dB which according to the app I used for this equals a quiet office. You can change your choices at any time by visiting Cookie preferences, as described in the Cookie notice. Its smooth-running, the SSO2 bearing of benchmark class and the proven premium quality from Noctua make it a first-class choice for the highest demands.

SSO2 bearing - The chromax line fans feature the further optimised second generation of Noctua's renowned, time-tested SSO bearing. Combined with the industrialPPC series’ robust polyamide construction and advanced protection features, this makes the fan ideal for challenging industrial applications.

can be used either to run the fan at a fixed speed of 1200rpm or to cap the maximum speed when using automatic PWM control. Integrated 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. The only difference I can think of is that Founders' Edition cards might be higher-binned chips for enthusiasts, but you aren't using an aftermarket waterblock anyway.

The fan will potentially run at full speed, so if you would like to reduce the speed of the fan you will need to adjust the fan speed setting in your BIOS or use fan control software such as SpeedFan in Windows.If the PSU is underneath it (or at least partially) one, or both of the fans can't get any air from in between the GPU and the PSU. Quality fan The fan is presented in a very smart box, and from the outset you can tell that it is a quality component. With SSO2, the rear magnet is placed closer to the axis to provide even better stabilisation, precision and durability. It will be only 3pin/FLX but you can set each fan individually vs using single mobo header and setting one curve to all connected fans.
