Proper way to control fan with a GTX 770 ?

What is the correct way to enable control of the fan within nvidia-settings. I have the 770 GTX and use the latest drivers.

I put this in my: /etc/X11/xorg.conf.d/20-nvidia.conf file.

Section “Device”
Identifier “Device 0”
Driver “nvidia”
VendorName “NVIDIA Corporation”
BoardName “GeForce GTX 470”
Option “RegistryDwords” “PowerMizerEnable=0x1; PowerMizerDefaultAC=0x3;”
Option “Coolbits” “12” <—8 & 4


Do I also need to put these in the “Device” section within my main ‘xorg.conf’ file within /etc/X11 ??

I am running Mageia (Cauldron) 64 Bit.
