Best quick/easy way to control case fan speed? - idillicah - 09-19-2020
Hello!
I have this case: https://kksb-cases.com/products/kksb-rock64-case-steel?_pos=1&_sid=1f3178bfc&_ss=r
It includes a little fan (which is quite noisy, haha), and it works fine just by using the pins on the board.
But it goes at full blast all the time. I was wondering if you guys could help me figure out a way to have a voltage control setup tied to CPU temp?
I remember seeing something for the RPi with Python, but I can't seem to find it.
any help is appreciated.

I've not tried these yet because I can't get my fan to respond at all (which GPIO pins did you use?) but they seem well-worth a look.

I use ats to control the case fan in my RockPro64, it works fine. I've also just manually set the fan speed with e.g.
echo 50 > /sys/devices/platform/pwm-fan/hwmon/hwmon3/pwm1
(You must be root of course)
edit: just realized this thread is about Rock64, not RockPro64...

If you don't want to spend CPU cycles soft-PWMing in userspace, you can use a microcontroller and gpio-fan in the dts to get the same thing done with no userspace daemons or python scripts.
