Did you get it?
also you can use nvidia-settings or nvidia-smi...
nvidia-smi just gave me a text readout. Didn't see way to edit anything.
nvidia-settings brings me to a nice nVidia GUI that I can go through. but none of the settings are editable. (greyed out). at least they were until I stumbled upon this setting to modify the xorg.conf file to add in "coolbits 28". Now the nvidia-settings can be changed a little.
I can modify the fan (which was one of my biggest things)
Now just trying to see if I can play with the clock/mem settings at all
