A simple kludge that can help you in this case:
Using some light cardboard or heavy paper, and some glue, make a duckt 
going between the fan of the video card and some opening of the case 
from whitch it can get fresh air.
Next, place another peice as a wall between the CPU and the video card 
to force the heated air away from the card.

You may also make a funel connecting to the CPU fan to help limit it 
re-aspiring it own heated air. Fashion it so that it goes toward some 
opening in the case or an intake fan.

anything else...
If you use corrugated cardboard, it's also somewhat effective at 
reducing the noise level a little.
