Fan header convertor for NOCTUA NF-A4x10 5V

[massager0313]

Hi, I’m looking for the fan pin header convertor for my NOCTUA NF-A4x10 5V

What’s the type of VF2 fan pin header? My noctua 3pin to 2pin convertor has different header

The Noctua NF-A4x10 5V PWM comes standard with a USB power adapter cable and this is the optimal adapter for connecting to 5V without PWM control.

Using Odroid XU4 fan on VisionFive 2

In the meantime, I ordered a Heat sink with fan for Odroid XU-4 - blue for each of my two VF2s and they were delivered within four days. And Botland sells cheaper and without penalty fee. I have combined the heat sinks with one NF-A4x10 5V PWM each, which I am still controlling with an Adafruit EMC2101 I2C PC Fan Controller on a Raspberry Pico W for the time being.

I have wired my Noctua 5V PWM NF-A4x10 directly to the fan header with dupont connectors. Soon, I intend to connect the PWM lead, possibly also the RPM lead, to the GPIO, and write a small program in Rust that responds to change in CPU temperature running as a Linux service under systemd. (I’ve been doing it this way with Raspberry Pi 4B for three years.)

A nice little starter project, as soon as I have 3D printed a case.

Thank you all for your answers, hmm I should’ve bought PWM type not the just 5V type.
If I come up with other solution I will post here, thanks again.

I am also a fan of PWM fans.

Control of 5V PWM fans, manually, with script and automatically by kernel

The topic of cooling has been addressed here in the forum on various occasions. Some consider fan-assisted cooling to be necessary, others swear by passive cooling and still others find the topic overrated and consider cooling of the VF2 to be unnecessary. Differing opinions on this subject are normal and perfectly fine. Here I would like to address only the first group and go through the possibilities of temperature-regulated PWM control together with you. Those who are concerned about cooling…

Using Odroid XU4 fan on VisionFive 2

It seems the Odroid XU4 fan is mostly compatible with the VisionFive 2: [IMG_0480] I had to remove the connector and replace it with one to fit the VisionFive 2, but it seems to be working well after doing that. I made some further notes on it in this post: VisionFive 2 hardware setup and costings – Graham Markall The idle temperature seems to have dropped down from about 50 deg C to about 30 deg C with the fan running. I have not yet tested it under load but will post some more details onc…

If you remove the PWM pin (third pin), and move the GND pin (first pin) to this position, you can plug the fan directly into the GPIO header. This may block access to 3v3 pins though. If you aren’t using GPIO, then this is a workable solution. It is what I do with my fan on VF2.
