Well, the fans just went 100% on kernel 4.4.14-040414-generic after about a day of normal operation. Any advice on what other information to collect?

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.
