Nvclock able to change fanspeed Nvidia-Settings not.

I am unsure of what the nvidia-auto-select mode does. If it helps, here are the applicable sections of my xorg.conf:

Section "Monitor"
    Identifier     "Monitor0"
    VendorName     "Unknown"
    ModelName      "Unknown"
    HorizSync       28.0 - 33.0
    VertRefresh     43.0 - 72.0
    Option         "DPMS"
EndSection

Section "Device"
    Identifier     "Device0"
    Driver         "nvidia"
    VendorName     "NVIDIA Corporation"
EndSection

Section "Screen"
    Identifier     "Screen0"
    Device         "Device0"
    Monitor        "Monitor0"
    DefaultDepth    24
    Option         "Coolbits" "5"
    SubSection     "Display"
        Depth       24
    EndSubSection
EndSection

Just let system to choose best choice. Nothing to do with the problem.

Have found on internet that /etc/X11/xorg.conf.d/50-device.conf have to be modified.

Section "Device"
#		Identifier "Default Device"
    Identifier  "Video Card"

#		Driver "radeon"
    Driver    "nvidia"

  ## Required magic for radeon/radeonhd drivers; output name
  ## (here: "DVI-0") can be figured out via 'xrandr -q'
  #Option "monitor-DVI-0" "Default Monitor"

    Option    "Coolbits" "5"

EndSection

Have removed /etc/X11/xorg.conf.

Command are accepted :

linux-srv:/local/zypper_install # /usr/bin/nvidia-settings -t --query [fan:0]/GPUCurrentFanSpeed 
53

linux-srv:/local/zypper_install # nvidia-settings -a "[gpu:0]/GPUFanControlState=1" -a "[fan:0]/GPUCurrentFanSpeed=90"

  Attribute 'GPUFanControlState' (linux-srv:0[gpu:0]) assigned value 1.

  Attribute 'GPUCurrentFanSpeed' (linux-srv:0[fan:0]) assigned value 90.

linux-srv:/local/zypper_install # /usr/bin/nvidia-settings -t --query [fan:0]/GPUCurrentFanSpeed 
90

linux-srv:/local/zypper_install # nvidia-settings -a "[gpu:0]/GPUFanControlState=1" -a "[fan:0]/GPUCurrentFanSpeed=30"

  Attribute 'GPUFanControlState' (linux-srv:0[gpu:0]) assigned value 1.

  Attribute 'GPUCurrentFanSpeed' (linux-srv:0[fan:0]) assigned value 30.

linux-srv:/local/zypper_install # /usr/bin/nvidia-settings -t --query [fan:0]/GPUCurrentFanSpeed 
30

Thank you for your help.
