## 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: 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.

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.
