Are you trying too keep voltages down too keep your fan speed down, or do your temps get too high at normal voltages?
Personally I would just try and live with it - my rig is SO loud now, but after a week ive gotten used too it.
Lower voltages are helping to keep my temps down and it is also reducing the stress on my PSU (every little bit helps).

Have you tried reversing the cards at all? Sometimes one of the two cards will by nature run cooler ... obviously you'll want to make that your top card.
The top card is the cooler card, but that is only because of the fan speeds. If I set my fans to run at 50%, then the top card's fan is rotating at 2600 RPMs, and the bottom card's fan is rotating at 2000 RPMs. That is a big difference as far as the amount of air getting sucked in to the top card compared to the bottom. If I set the speed to stay at 50% up until 70C, then the bottom card will kick into a faster speed as it will reach that 70C barrier quite quickly (being that the fan is only running at 2000 RPMs). Yet, that higher speed is still relatively quiet, and lets my card settle at about 74C under intense gaming. On the other hand, when the top card reaches 70C, and the speed increases by the same amount as both card are bound by the exact same fan profile, the fan becomes a leaf blower. Yes, it will cause the card to cool down even faster and return to under 70C, but then that will cause the fan speed to drop again and the card will hit that 70C barrier again. Thus, the top fan is switching back and forth between quiet and a leaf blower, and it is very, very annoying. Hence, my need for separate fan profiles.
