Title: CPU/GPU Fans suddenly go 100% RPM on Asus ROG G752VT Status in linux package in Ubuntu: Incomplete Bug description: 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. --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.2 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC1: whale 3068 F.... pulseaudio /dev/snd/controlC0: whale 3068 F.... pulseaudio CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 18.04 HibernationDevice: RESUME=UUID=ada9b595-bbf2-40a3-8575-5908492bb969 InstallationDate: Installed on 2014-10-20 (1333 days ago) InstallationMedia: Ubuntu 14.04.1 LTS "Trusty Tahr" - Release amd64+mac (20140722.2) MachineType: ASUSTeK COMPUTER INC.
