Adjusting fan speeds when using SLI

Ok, so I am having a little bit of a problem with manually controlling my fan on my second video card. I have used both rivatuner and even the the nvidia tool (I know that it is very unreliable and is not very effective).

The primary card will run at 95% fan speed at all times like I have set it to run, but the second card will revert right back to auto (when it runs at auto-adjusting it never rises above 10% fan speed). I have to minimise and manually ramp it up to 100% for a bit to cool it off when I am done playing or if I minimise. The core on the second card rises to mid and upper 70's now, yet the primary card's core caps out in the 50's.

I have 2x XFX GeForce 8600 GTS XXX cards SLI'd. I thought that it might be a driver issue, but I have reinstalled drivers twice now and it doesn't seem to help. I have Rivatuner set to have the fans run at 95% on startup, but only the primary fan takes effect. I even altered the nvidia control panel default profile settings to run both at 95% fan speed, but that still doesn't help my second card. Anyone know of a way to fix this?
 
I've never seen this problem before, but I'm going to link to this RivaTuner guide anyway: http://www.vaguesoft.com/index.php?pageid=rt207. This might help, setting up core specific fan settings. I use it on my SLI 8800gt setup, and it runs perfectly. Make sure you have the hardware monitor recording at all times. It doesn't have to log any data, just run.
