I noticed I get fan settings if I add a Coolbits option under my xorg.conf for the device since asking my question. I can not find a list of various coolbits anywhere with Google, but found on the ArchLinux a setting of "4" gives me manual fan speed control. When automatic since the latest update the fan doesn't go over 40% though. I will try the debian packages but I'll have to uninstall the current driver. I like to run the latest drivers so I really prefer to just install from nvidia's upstream binary blob installer.
