    How to detect and control fans speed

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

    Code:
    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 :
    Code:
    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:
    Code:
    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?

    First thing I would check is to see if the software installed ok. Any errors in dmesg, or /var/log? If all is well there, I'd check the manufacturer's site, and verify the fan speed control work on non-Windows o/s.

    I don't see the error. It's a message. What problem are you facing?

    Just FYI, not all laptops allow to control it.

    Thanks for the reply. So whether it will be controlled from the BIOS automatically?

    Ya its a message which i also commonly seen on the internet for different distros but they have solved their problem in some cases. I was trying to follow this guide for the fan control after which i struck at that place.

    Thanks

    Thanks for the reply but i was unable to find that whether my fan will be controlled in non-windows os.
