## Overview

The Noctua NF-A4x10 5V PWM is a premium, ultra-quiet 40x40x10 mm fan designed for efficient cooling in compact setups. Powered by 5V with PWM speed control, it delivers up to 5000 RPM while maintaining a whisper-quiet 19.6 dB(A) noise level. Its advanced acoustic frame and Flow Acceleration Channels optimize airflow and reduce noise, making it ideal for Raspberry Pi cases, 3D printed projects, and other small electronics. The included USB power adaptor and anti-vibration mounts provide versatile, stable, and easy installation options.

## Description

Premium 40x10mm fan with Flow Acceleration Channels and Advanced Acoustic Optimization for superior quiet cooling. Includes USB power cable with PWM speed control.

Review: Teeny USB powered quiet fan, perfect! - Purchased for a 3D printed project, works an absolute treat! So long as Noctua fans stay consistently great I'll be consistently brand loyal, nice and quiet with good airflow.
Review: Great for a Raspberry Pi case! - I bought this fan as I wanted to use it as an extractor on a Raspberry Pi case - I needed something small, silent and low voltage so it could be run from the Pi's USB ports. This fan achieved all those goals and more! It came with a USB adapter, which left the cable pretty long - too long to go a few cm into a USB port on the side of a Pi - so I cut the wires and soldered the USB connector directly on to the wires leaving the fan housing - very simple to do thanks to the nice design from Noctua and it's happily doing its job of keeping a Raspberry Pi nice and cool. Obviously at 5v it doesn't have a lot of oomph, but for its size and how silent it is, it does move a good amount of air. Impressed and recommended for smaller projects such as Raspberry Pi based builds!

A: Mind is controlled but done with firmware.  It is super quiet thou

**Q: What resistors do i need to work with my raspberry pi 4 pwm**
A: Depends on how your attaching it, I'm using it via the enclosed usb adapter for past 6 months, but it runs constant, I have purchased a 2n2222 npn transistor but not used it yet in conjunction with pinouts for temperature control.

*by G***P on 14 February 2021*

Best cooling fans you can buy. Used a lot of these fans of various size and voltage. Very quiet and efficient. Many connection cable options are provided for speed control or direct control together with low noise/vibration mounting pieces. Very long working life with sealed bearings and a six year Warranty. Highly recommended.
