Review: Le silence - Très très très silencieux, un peu léger pour le refroidissement mais c'est parfait pour mes besoins
Review: Silencioso - Increíble cómo algo tan pequeño puede mover tanto aire sin sonar como un mosquito enfadado. Lo he usado para sustituir el ventilador de serie de una impresora 3D y el cambio es brutal; ahora el silencio es casi total. Noctua nunca falla con la calidad de sus rodamientos.

## Questions & Answers

**Q: I need to control the speed using arduino (the arduino has a 500 hz pwm frecuency) can this fan handle this frequency for pwm or what it is?**
A: You can change the PWM to FAST PWM for these applications on Arduino. Googalize "25k PWM Arduino code". The real issue is trying to find data specs on the PWM IC that Noctua uses. Googalize "Noctua PWM white paper" and you'll get all the info you need on their PWM specs. Target frequency is 25kHz but the acceptable range is 21kHz to 28kHz. GOOD LUCK.

**Q: Is there a 5vdc pwm temperature controller for this fan? been searching, but can't find.**
A: No its controlled by the motherboard.  I threw away the usb adapter cable, If it was used to power the fan, since usb is 5v, I would expect it to run at full speed.  I used my fan on an NVIDIA NANO Single board computer

**Q: how long is the cable, from the fan all the way to the usb connector?  i want to put this in a small area, so looking for one with a very short cable**
A: 40cm.

**Q: is there a usb version of the noctua 40x20 5v fan**
A: No, there is no USB specific version available. But the kit does include a USB Type A to 4-pin female adapter cable.

### ⭐⭐⭐⭐⭐ Klein, leise und zuverlässig – typisch Noctua
*by L***R on 10 July 2026*

Der Noctua NF-A4x10 5V PWM ist für mich einer der besten Lüfter in dieser Größenklasse – da gibt es eigentlich nicht viel zu sagen. Die Verarbeitung ist, wie von Noctua gewohnt, erstklassig und der Lüfter arbeitet trotz seiner kompakten Abmessungen angenehm leise. Dank der PWM-Regelung lässt sich die Drehzahl präzise anpassen, sodass bei geringer Last kaum etwas zu hören ist und bei Bedarf trotzdem eine überzeugende Kühlleistung zur Verfügung steht. Zum Lieferumfang gehören zudem hochwertiges Zubehör wie Entkoppler und Adapter, sodass einer unkomplizierten Installation nichts im Weg steht. Wer Wert auf Qualität, Langlebigkeit und einen leisen Betrieb legt, macht mit diesem Lüfter nichts falsch. Klare Kaufempfehlung!
