We found a few 3D prints to use these fans with a Raspberry Pi too!\u003c\/p\u003e\n\u003ch3\u003e5V PWM version\u003c\/h3\u003e\n\u003cp\u003eMany devices such as network or storage solutions use 5-volt 40mm fans with PWM speed control. With the same operating voltage, PWM support and the included OmniJoin adaptor set that makes it compatible with proprietary fan headers, the NF-A4x10 5V PWM is ideal for replacing noisy or broken 5V 40mm fans with PWM.\u003c\/p\u003e\n\u003ch3\u003eReduced motor hub size\u003c\/h3\u003e\n\u003cp\u003eThanks 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.\u003c\/p\u003e\n\u003ch3\u003eFlow Acceleration Channels\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eAAO frame\u003c\/h3\u003e\n\u003cp\u003eNoctua’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.\u003c\/p\u003e\n\u003ch3\u003eStepped Inlet Design\u003c\/h3\u003e\n\u003cp\u003eNoctua’s Stepped Inlet Design adds turbulence to the influx in order to facilitate the transition from laminar flow to turbulent flow, which reduces tonal intake noise, improves flow attachment and increases suction capacity, especially in space-restricted environments.\u003c\/p\u003e\n\u003ch3\u003eInner Surface Microstructures\u003c\/h3\u003e\n\u003cp\u003eWith 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.\u003c\/p\u003e\n\u003ch3\u003eIntegrated Anti-Vibration Pads\u003c\/h3\u003e\n\u003cp\u003eIntegrated 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.\u003c\/p\u003e\n\u003ch3\u003eCustom-designed PWM IC with SCD\u003c\/h3\u003e\n\u003cp\u003eSupporting fully automatic PWM speed control, the NF-A4x10 5V PWM uses Noctua’s custom-designed NE-FD3 PWM IC that integrates Smooth Commutation Drive (SCD) technology. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus makes the fan quieter at low speeds.\u003c\/p\u003e\n\u003ch3\u003ePolarity protection\u003c\/h3\u003e\n\u003cp\u003eAs many devices using 5V fans feature proprietary connectors, and documentation of the pin alignment may not be available, the fan features an integrated diode for polarity protection. This way, you’re on the safe side if you accidentally connect it with reverse polarity.\u003c\/p\u003e\n\u003ch3\u003eSSO2 Bearing\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003ch3\u003eOmniJoin Adaptor Set\u003c\/h3\u003e\n\u003cp\u003eMany devices featuring 40mm fans use proprietary fan headers, so the NF-A4x10 comes with Noctua’s OmniJoin adaptor set. Just cut the original fan’s cable, fix it to the adaptor using the supplied 3M Scotchlok connectors and you can plug the NF-A4x10 to proprietary fan headers!\u003c\/p\u003e\n\u003ch3\u003eUSB power adaptor cable\u003c\/h3\u003e\n\u003cp\u003eThe fan includes a USB power adaptor cable that allows it to run on power banks, devices with USB host ports or USB power supplies such as those used for smartphones, giving you near endless possibilities for using the fan in your home, in your car or wherever a need for cooling occurs!\u003c\/p\u003e\n\u003ch3\u003eExtensive cabling options\u003c\/h3\u003e\n\u003cp\u003eThe fan’s short 20cm primary cable minimises cable clutter in typical applications while the supplied 30cm extension provides extended reach when necessary.
