Some NVidia cards actually allow you to control the fan speed in
software -- might look into this before cutting wires and soldering
resistors. I will be doing this too (on my PCI 8400 GS) as soon as I
get my distro installed and working. I may need a better heatsink
though, as even with the fan full-speed the heatsink gets hot to the
touch just in console mode!

I believe you will just need to experiment, gradually slowing it down
until video stutters. Then gradually start undervolting it until it
becomes unstable. Please keep us posted on any progress you make, and
I will post here too if/when I get mine working too.
