• Concerns about sensors-detect dangers (trying to adjust fan speeds)

    The last few months I’ve been wanting to adjust the fan speed on my laptop (a Lenovo 310-15ISK) through fancontrol, but have been hesitant due to # sensors-detect being able to “permanently damage hardware”.

    However, I am able to run $ sensors to monitor temperatures (and nothing else apparently).

    $ sensors
    Adapter: Virtual device
    temp1:        +31.0°C  
    Adapter: ISA adapter
    Package id 0:  +30.0°C  (high = +100.0°C, crit = +100.0°C)
    Core 0:        +28.0°C  (high = +100.0°C, crit = +100.0°C)
    Core 1:        +29.0°C  (high = +100.0°C, crit = +100.0°C)

    That got me thinking, is running # sensors-detect necessary in order for $ sensors to be able to measure temperatures?
    In other words, has # sensors-detect been automatically executed during the installation process?

    And if yes:

    • Since no fan seems to be detected, does that mean I cannot adjust its speed?
    • Does this make it safe to run it again, myself?
  • I should also mention that neither can # tlp-stat measure the fan speed:

    +++ Temperatures
    CPU temp               =    31 [°C]
    Fan speed              = (not available)

    (sorry, for some reason I could not edit my initial post)

  • Use sensors-detect as root to detect and generate a list of kernel modules.
    Note: A systemd service is automatically enabled if users answer YES when asked about generating /etc/conf.d/lm_sensors.
    Answering YES also automatically starts the service (immediately)

    But mostly it is not hanging sensors output to get more sensors visible…
    Some sensors modules seems to be not ctiv without so give it a try, it will not harm your system in mostly all cases ( ;) )
