That's about the maximum you want them to be at, I'd suggest getting more fans.

Is your case closed? If so try leaving it open and letting it breathe open air for a while and see where the temps go. If they go down then you need more airflow in and out of the case. Also if they are side by side I would suggest loosening up the screws and putting a spacer between the tops of the cards so that they have can bring in more air.

Watercooling is not really a good idea due to complexity and cost.

Are you overclocking? If so, turn it down, and be sure to lower the memory clock as low as possible.

It's possible the ambient temp in your room is too high as well.

What case do you have them in? 6990's are pretty big and with dual gpu's they are putting off a lot of heat. Compounded by the fact that they blow some of that hot air back into the case from the back end of the card. You need a case that can ventilate a lot of heat.

I would place the mobo on a desk somewhere, your temps will probably drop by 15 degrees celcius.

You didn't have the fan maxed? No wonder it was hot.

...You don't max gpu fans for no reason.
Especially the 6990, at maxed its about 80 decibels, which is over the safety limit for humans.

It's better to be pissed off, than to be pissed on.

you are going to struggle in the summer with that setup, I have an antec 300 which for a budget case has excellent airflow had a 6870 +5870 in there, I'm thinking about picking up one of the HAF or lanboys (antec man). Invest in a good case it will save you stressing about coming home to a towering inferno.

It's only going to get hotter, but you can always adjust your core clock and turn it down a notch if it must be. There are always options to keep it running within reasonable temp, but you just might not like the ghash out of it. Ambient really is big part of keeping temps low regardless of fan speed after a certain threshold.
