Review: Noctua NF-A4x10 5v PWM Fan In my opinion, these fans live up to their premium quality advertisement. Build quality is excellent, noise is very minimal, and the 40 millimeter depth allows for extra airflow. You may not enjoy the color but I'm confident you will enjoy the quality and performance. Used to cool to steering wheel pedal sets they perform quite well and are nearly silent. Cooling is very efficient. These can be mounted with screws or with the included rubber grommets. Please bear in mind these are for 5 volt current not 12 volt. They will work with both PWM or direct voltage applications
Review: El ventilador del mini pc minisforum, funcionaba irregularmente, haciendo a menudo un ruido escandaloso, como no encontraba recambios me decidí a buscar un ventilador con connector de 4pins a 5v para remplazarlo a mi manera (ver fotos 😅) La verdad es que esto muy contento, como el ordenador esta escondido y no se ve, me da igual su apariencia, y este ventilador Noctua funciona de maravilla y de forma muy silenciosa. Me sorprendió por su precio, la cantidad de accesorios que trae consigo, adaptador usb, cable alargador, tornillos, gomas de anclaje, etc. Se nota que es un producto de mucha calidad, hasta tiene las esquinas blandas para evitar al máximo transmitir las vibraciones del mismo al ordenador y evitar así amplificar el poco ruido que pueda hacer

## 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.
