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

Product Information

N.A 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. We ship all products in unopened boxes directly as received from our manufacturer in brand new and in perfect condition.

This problem also occurs if you try to use an in-line fan speed controller such as the one made by Gelid.Swap has an MTBF specification of over 150,000 hours and is delivered with a full six-year manufacturing warranty. 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. Acceleration of the airflow in the critical outer regions of the fan blades reduces suction vortex shedding, resulting in higher efficiency and lower turbulence-induced noise emissions. 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.

So you can plug the 4-pin fan connector onto the 3-pin motherboard fan header, leaving the fourth pin not connected to anything. The NF-A14 is a premium quality quiet 140mm fan with a square frame that complies with Noctua’s AAO(Advanced Acoustic Optimisation) standard. Having received more than 100 awards and recommendations from the international press, Noctua’s NF-A14 has become a proven premium choice for 140mm cooling needs. Stops at 0% PWM - When the fan is set to 0% PWM duty cycle by the motherboard or PWM fan controller, it will stop. The anti-vibration pads made from extra-soft silicone reduce the transmission of minimal vibrations and are compatible with all standard screws as well as standard mounting systems or fan brackets used with CPU coolers.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. Like all Noctua fans, the NF-A14 has an MTBF specification of over 150,000 hours and comes with a full 6-year manufacturer's guarantee. It will use voltage control to them, but get as accurate as you can with PWM connection (since most mobos only offer pure fan control on CPU header anyway). The NF-A14 offers sophisticated aerodynamic design measures such as flow acceleration channels and improves the well-known low-noise cooling performance of the award-winning NF-P14. They're in the front of my Fractal Define R6 so thankfully I can't see them and they don't clash with the theme of my build.
