Ideal for integration into heatsinks and compact devices
Proven NF-A4x10 design provides outstanding performance-to-noise efficiency
Available in 24, 12 and 5V with different connectors and cable lengths
Having received more than 50 awards and recommendations from the international press, Noctua’s NF-A4x10 has become a proven premium choice for 40mm cooling needs. Its renowned efficiency has convinced tens of thousands of customers all over the world.
The frameless n-version of the NF-A4x10 is ideal for direct integration into custom heatsink designs and compact devices where it can be helpful to push air out both in axial and radial direction. Three small screw mounting tabs ensure easy installation as well as consistent cable routing.
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.
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.
Supporting fully automatic PWM speed control, the NF-A4x10 PWM uses Noctua's novel, custom-designed NE-FD1 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 lower speeds.
When the fan is set to 0% PWM duty cycle by the motherboard or PWM fan controller, it will stop. This makes it ideal for creating setups with semi-passive cooling that automatically turn the fans off and thus run completely silent at idle if thermals allow.
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.
For B2B clients, we can offer the NF-A4x10n in 24, 12 or 5V variants with customised cables and connectors. Please contact us at b2b@noctua.at if you’re interested in integrating the NF-A4x10n into your device.
Noctua fans are renowned for their impeccable quality and outstanding longevity. Like all Noctua fans, the NF-A4x10 features an MTTF rating of more than 150,000 hours and comes with a full 6-year manufacturer's warranty.
