    Thanks for you post
    I have a H340 running 12.04 with 3 x 2TB drives
    I use snapraid daily to create a recoverable image incase a drive goes down ( which it has in past)
    I also have the LEDbrightness controll working.

    The one thing I would like to do is increase the H340 side fan to 1100 as you have done

    I would like to do this manually
    Hand you give me some idea how you did this as I find conflicting approaches on the NET


    Ps I have looked at replacing by Synology or Pegasus but always come back to my comfig as the best option for me

    Did you install the amd64 or i386 version of Ubuntu server? Since the atom z230 is a single core CPU, I suspect it will not support 64 bit OSs, is it correct? I would like to change my H340 to Ubuntu recently and hence this question. Thank you!

    Hello, i do not have the /sys/devices/platform/dme1737.2160/, i am on debian 9.8 on a acer easystore H341. Slightly different CPU, thats all, i think…

    I did a “find /sys/ -name “*pwm*”, which turned up 0 results, and a
    rgrep “pwm” /sys/ >/pwmlist 2>/pwmlist2, that filled the “pwmlist” file with
    /sys/kernel/debug/tracing/available_filter_functions:pwm_get_backlight [i915]
    /sys/kernel/debug/tracing/available_filter_functions:pwm_set_backlight [i915]
    /sys/kernel/debug/tracing/available_filter_functions:bxt_hz_to_pwm [i915]
    /sys/kernel/debug/tracing/available_filter_functions:spt_hz_to_pwm [i915]
    /sys/kernel/debug/tracing/available_filter_functions:lpt_hz_to_pwm [i915]
    /sys/kernel/debug/tracing/available_filter_functions:pch_hz_to_pwm [i915]
    /sys/kernel/debug/tracing/available_filter_functions:i9xx_hz_to_pwm [i915]
    /sys/kernel/debug/tracing/available_filter_functions:i965_hz_to_pwm [i915]
    /sys/kernel/debug/tracing/available_filter_functions:vlv_hz_to_pwm [i915]
    /sys/kernel/debug/tracing/available_filter_functions:pwm_enable_backlight [i915]
    /sys/kernel/debug/tracing/available_filter_functions:pwm_setup_backlight [i915]
    /sys/kernel/debug/tracing/available_filter_functions:pwm_disable_backlight [i915]
    where would i go to change those PWM settings?
