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.
Using that, I made my CPU run about 10° to 15°C cooler without changing
anything else...
If you use corrugated cardboard, it's also somewhat effective at
reducing the noise level a little.
