Hello
I just tested it and found no problem.
You may need to update your kernel to the latest version.
pi@raspberrypi:~/x729-script $ uname -a Linux raspberrypi 6.6.51+rpt-rpi-v8 #1 SMP PREEMPT Debian 1:6.6.51-1+rpt3 (2024-10-08) aarch64 GNU/Linux pi@raspberrypi:~/x729-script $
The fan is running normally.

1 day ago Hello,
I am using Ubuntu 24.04 Server.
:~$ uname -a
Linux userver 6.8.0-1015-raspi #17-Ubuntu SMP PREEMPT_DYNAMIC Mon Nov 11 14:12:16 UTC 2024 aarch64 aarch64 aarch64 GNU/LinuxWhen I power on my setup, I notice that the FAN is not rotating. I am not using accumulator batteries at the moment on the X729 board.

20 hours ago We have tested Ubuntu 21.10 on RPi4 and the script works. OS is changing, kernel is changing, we need some time to test the script on Ubuntu 24.10 server on RPi 5 and update it We recommend you to use the Raspberry Pi official OS bookworm

15 hours ago I have tried with the Raspberry Pi official OS bookworm and it works. However, it is strange why it is not working with the Raspberry Pi official Ubuntu Server 24.04.1. If you could share some ideas, it would be highly appreciated. Thank you.

1 hour ago I add a pythone file (sample/pwm_fan_control_gpiod.py) to control pwm fan on ubuntu 24.04 server, and it can works.
Before that, you need to install the libgpiod library using the following command.
sudo apt install gpiod
sudo apt install python3-libgpiodThen run the command python3 pwm_fan_control_gpiod.py to make PWM fan work properly.
PS: I actually used ChatGPT to help me do this.
There is an error in the "Configuring Different gpipchip number and pwmchip number for Raspberry Pi 5 hardware" section at https://wiki.geekworm.com/X729-script web page.
sed -i 's/pwmchip0/pwmchip2/g' x729-fan.shThis command is changing pwmchip0 to pwmchip2 value in the x729-fan.sh script. It is incorrect because the Pi 5 board is using pwmchip0 as shown below:
Also, it can be proved according to the journal log where it is clearly seen that the service is failing with error.
I have changed pwmchip2 back to pwmchip0 in the x729-fan.sh script, but the fan is not working.
Could you assist please if the problem with the fan itself or if the script is not working as expected? This is a new x729 board that I recently received.
