Hello there,
I am currently using Lenovoy50-70 with kali linux 2017.3.

uname -a
Linux abhi 4.14.0-kali1-amd64 #1 SMP Debian 4.14.2-1kali1 (2017-12-04) x86_64 GNU/Linux
I have tried some solutions like :
sudo apt-get install lm-sensors 

sudo apt-get install fancontrol

sudo sensors-detect

sudo service kmod start
I am getting problem in following output:
sudo pwmconfig
# pwmconfig revision 6243 (2014-03-20)
This program will search your sensors for pulse width modulation (pwm)
controls, and test each one to see if it controls a fan on
your motherboard. Note that many motherboards do not have pwm
circuitry installed, even if your sensor chip supports pwm.

We will attempt to briefly stop each fan using the pwm controls.
The program will attempt to restore each fan to full speed
after testing. However, it is ** very important ** that you
physically verify that the fans have been to full speed
after the program has completed.

/usr/sbin/pwmconfig: There are no pwm-capable sensor modules installed
I tried to solve above problem but no luck. Any suggestion?
