Hi Dan, Sorry for the delayed reply here. > as a fresh owner of the Helios4 NAS (batch 3) I've prepared a rpm with > some bits to make the user experience better.

I'll take a look at that, should be straight forward to fix. > - udev rules for the temperature sensors symlinks from Armbian > - fancontrol config file using the symlinks > - Requires: lm_sensors for fancontrol, i2c-tools for the OLED display > shipped with batch 3 So I think most of the above things around fan control should be handled with a cooling-map, then it would be handled automatically by the kernel thermal subsystem. You can see an example ine Odroid XU* devices in the upstream and looking at the Helios4 DT I don't think it should be too difficult to add. It would negate all of those bits. arch/arm/boot/dts/exynos5422-odroidxu3-common.dtsi > The fancontrol config is set for the single PWM control (j10) that's > available in mainline (and Fedora) kernels.
