editing fanspeed

[axed]

I have a 9500GT that I would like to edit the fan speed. I got a new heatsink/fan for the graphics card, but the new fan does not spin fast enough. I need to change the fanspeed to higher rpm. In windows, I used the nvidia control panel to set the fan speed, but I have a hackintosh and cannot use any Windows software programs, so I need to manually edit the fanspeed in the BIOS. I saved the bios file with gpu-z and tried to edit the fanspeed with nibitor, but all the fan settings are grayed out. I was wondering what I am doing wrong here?

How many pins come off of the GPU fan? If it's two, there is no fan control.

There was two pins on the original fan and also the replacement fan, I am able to control the fanspeed through nvidia control panel, but this is not an option for me when I am using OS X. According to gpu-z, the default fanspeed runs at 30%. I would like to change the fan speed to a higher speed.
