I'm glad it worked for SLI tooribbell:
worked a bit on the SLi deal this afternoon.
used the optimized dynamic control rules under the low level, with cloning enabled.
worked as advertised.
confirmed by GPU-z that both cards are ramping up their fans and the hardware monitor in RT notes a nice duty cycle curve.
only problem is the 8800 GTs have god-awful fans and sound like mini leaf blowers when they are ramped to 100%.
thanks again for the advice.
