How to reduce the first-speed fan speed of VIM3 under the CoreELEC system?

Hello @UncleFat2026

If your VIM3 MCU version is 0x03 and above then you can control the speed via the duty.

Check the MCU version:

i2cget -f -y 4 0x18 0x13

Setup the FAN PWM duty: 0~100

e.g. setup 30% duty.

i2cset -f -y 4 0x18 0x8a 30
