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.
