** Description changed:

  After upgrading from Ubuntu 16.04 to 18.04, I've noticed that CPU and
  GPU fans suddenly go full throttle. It doesn't seem to depend on
  temperature, could happen when 32 °C reported, sometimes the laptop can
  work for day or two without this issue, but eventually it happens. The
  only way to stop fans is to power off the laptop, power on (fans go 100%
  at this point again), power off during BIOS splash screen and power on
  again. Seems to happen more often after waking up from a sleep.
  
  Things tried:
  
  Upgrading BIOS to latest available on ASUS site to the date of writing.
  No change.
  
  asus-fan kernel module (https://github.com/daringer/asus-fan). Detects
  both fans and shows correct speed in /sys/class/hwmon/*/fan{1,2}*, but
  does not seem to control it and does not prevent going full throttle.
  
  4.17.0 kernel from Ubuntu mainline builds. Doesn't seem to affect the
  issue.
  
  Userspace fan control software (https://github.com/hirschmann/nbfc). Can
  control speed of both fans to the point where they go full throttle,
  after that has no effect on them.
