I just installed ubuntu and I'm trying to fix the fan issue because it's alwaysi working , even when I open the laptop, I'm using an asus rog. I was trying to follow this tutorial How to control fan speed? but got stucked to the part when I type sudo pwmconig , there it asks me 

Are you sure that
you want to setup this output for manual control? (n)

and after I press n, it says There are no usable PWM outputs. Any tips for solving would be highly appreciated, really looking to fix this major issue. BTW, I installed lm-sensor and this is what I got till the end

                       (emerg = +135.0°C, hyst =  +5.0°C)

I've faced the same problem on a similar Asus laptop and ended up writing my own fancontrol config, since I was unable to get pwmconfig working.

Here's what I ended up using.

/etc/fancontrol

INTERVAL=2
DEVPATH=hwmon3/pwm1=
DEVNAME=hwmon3/pwm1=
FCTEMPS=hwmon3/pwm1=hwmon3/temp1_input
FCFANS=hwmon3/pwm1=hwmon3/fan1_input
MINTEMP=hwmon3/pwm1=50
MAXTEMP=hwmon3/pwm1=100
MINSTART=hwmon3/pwm1=60
MINSTOP=hwmon3/pwm1=30
MINPWM=hwmon3/pwm1=30
MAXPWM=hwmon3/pwm1=255

With this config I could start fancontrol by running sudo fancontrol and as a deamon with sudo service fancontrol start

I found it useful to run watch sensors and stress --cpu 4 when tweaking the config to confirm that fancontrol keeps the temperature at a ok level, even when all cpu cores were running at 100%.
