Featuring advanced aerodynamic design, 4-pin PWM speed control (1000-5000 RPM), and anti-vibration mounts, it delivers efficient airflow with minimal noise (19.6 dB(A)) and exceptional reliability (>150,000 hours MTTF). Perfect for professionals seeking silent, precise thermal management in tight spaces. ## Description Product Description Featuring advanced aerodynamic design measures such as Flow Acceleration Channels and Noctua’s AAO frame, the NF-A4x10 is an award-winning, premium-quality quiet fan in size 40x10mm. 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 as well as an OmniJoin Adaptor Set for easy connection to proprietary fan headers. Its superb running smoothness, reference-class SSO2 bearing and Noctua’s trusted premium quality make it an elite choice for the highest demands. 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. Flow Acceleration Channels The NF-A4x10 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 Bearing The NF-A4x10 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 Pads Integrated Anti-Vibration Pads made from extra-soft silicone minimise the transmission of minute vibrations while maintaining full compatibility with all standard mounting systems and fan clips used on heatsinks. Inner Surface Microstructures 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. Reduced motor hub size Thanks to its streamlined, compact motor design, the NF-A4x10's motor hub is smaller than with conventional 4cm fans. This allows for more blade surface area and thus contributes to the NF-A4x10's superior airflow and pressure performance. Review: Amazing tiny little fans! - Almost silent all the time; even at max speed they will not be audible at all with headphones on. Great little fans which can be used to replace PSU fans, or as case fans in a tiny ITX build. Installation was super easy and comes with all the required mounting hardware, and also pairs well with a fan splitter. I used these in a 3D printed bracket for a Jonsbo NV10, and they work great! Slightly questionable value for money for such small fans but performance is so good that I cannot really complain! Review: Great Fans To Help Move Heat From Confined Spaces - Noctua are a known and very good brand of fans. I don't use Noctua as my case fans as the aesthetic does not fit my build. However, the back of my PC gets very warm. I am running a 5080 and a 13th Gen Intel along with a 1000W PSU. This generates quite a bit of heat. Whilst the case fans (Lian Li TL LCD and non-LCD) do a great job of getting the heat from the main case, heat accumulates in the back where my cabling is. I have put two of these very small fans in the rear of my case to help exhaust some of the heat and reduce the temperature inside the cabling compartment. They are PWM so I am running these from their own header and set the fan speed to around 80% minimum which is around 5000rpm (in the BIOS with System temp as the monitor). If the system temp gets over 45 deg, the fans will ramp to full speed which is around 5500rpm. These do not move massive amounts of air like case fans do, but they seem enough to deal with light scenarios. They function as they should. Fast and very, very quiet. In fact, so quiet, I cannot hear them at all (but they are in the rear so quite well sound insulated). Pretty good value for money. At £14 per fan, they are not the cheapest, but you are paying for quality (they come with a 6 year warranty which is nice). Plenty of cabling options in the box also. You might need an extension cable if you have a large case and, therefore, quite a long run. Overall, they are small, spin and move air in the direction you want!

You need to identify which leads on the Noctua are 12V and Ground. The colour code is not obvious. The Noctua does come with a short 12v + Ground cable to adapt the pins to whatever plug you are connecting too. It comes with handy Scotchlok connectors to facilitate this. **Q: Which way round to install, blow ambient air onto the hot area or 'suck' air away from the hot area ?** A: Only true answer is try both ways and see what works best for your setup, I have mine blowing on the components but they are right next to an intake fan **Q: Could i rewire this to a gpu ph2.0 mini 4pin? the 40mm fan on my motherboard is dodo, but uses this connection instead of a standard 3/4pin header.** A: As long as you know which wire is which on your motherboard yes absolutely ## Customer Reviews ### ⭐⭐⭐⭐⭐ Amazing tiny little fans! *by J***. on 29 May 2026* Almost silent all the time; even at max speed they will not be audible at all with headphones on.
