I will tune the fan controls later to give more fine control. It is all about the duty cycle and period of square wave. We might be looking at 50-200Hz instead of last released 1kHz, and previously 100kHz.

The command on its own when entered into terminal results in "command not found". It seems like a bash file, but when I searched for it: no results. If it is a bash file, where is it located so I can test it?

Code:
/usr/local/sbin

Currently the fan works in an on/off mode (at least for me):
Code:
nano /sys/class/hwmon/hwmon0/pwm1


The range should be from 0 - 255, but for now ... for me ... 0, 1 and 2 are 'off' while 3 and up is 'on'.

I connected a standard 12 V computer case fan. Around 80 the fan starts spinning slowly. But it vibrates until I set the value around 240.

Couple of things: I am still new to all of this too so I am with you! Have you successfully booted your machine and cannot get the fan to work or are you asking how to get everything set-up for the first time? If you need help getting it set-up the Noob page is where I started. 

If you just need help with the fan, then log into the terminal and type in the code that starts with "nano" in the reply above. It should pull up a screen with a zero in the top left and some commands at the bottom. Change that zero to a number between 0-255 then hit Ctrl+X and type Y or yes when it asks if you want to over write. That should turn your fan on. I am having an issue though with these settings not being enforced when I reboot. So I have to go back in to turn the fan back on.

I connected a fan but I'm not sure it's getting enough power. It's a 120mm fan. Am I risking damage with this size fan?

Hello gonde,
There are different possibilities for that..
On kernel 4.4.138-1097-rockchip-ayufan-gb5128c0a1684( its what I have ), I use ats
But with newer kernels I don't know if it work ok( I haven tested yet )

Then you would  be able to control Fan, with that Tutorial..
