Fan control on second video card?

[allenbina]

BACKGROUND:

I have two 9600gts in sli that I use to game lightly in windows. I use my machine mostly in windows but need osx for some work in final cut pro. I installed osx with only one video card (added efi strings in aitkos v7) and it works great, both dvi connections work, fan control works, the whole lot. The problem is every time I want to use osx, I need to open my case, take one card out (unplug hds too, but thats because for some reason osx likes to make errors on my ntfs formatted disks) and restart my computer.

 

Osx boots fine with both cards, the first card is still recognized and both monitors work on the card, but the second card is not recognized (to the best of my knowledge. no dvi connections work on it). at boot, it is normal for the video card fan to spin at 100% until it gets into an os (.nix / win) when something throttles down the speed of the fan based on temps. When i boot into osx with both cards, the second card continues to spin at 100% which drives me insane. This thing is loud and high pitched.

 

QUESTION:

I want to know how to control the speed of the second video card fan (without taking it out ).

 

SETUP:

I have a p5ne-sli that uses the nforce chipset. It works great with iatkos 10.5.7 and the voodoo kernel w/ chameleon 2. Two 9600gt 512 msi cards. 4 gigs of memory. nforce ethernet works finally. nothing else plugged in. The efi strings I added were the dvi / dvi from the iatkos v7 dvd.

 

BACKGROUND:

I have done lots of research and I'm either too stupid to figure it out or its a lot of spam or the blind leading the blind. If anyone has any ideas, it would save me from opening my case every time I want to boot into osx.
