Having an exhaust fan will just make a low pressure spot there, meaning all that air coming in is just going to flow towards the exhaust fan. Another way to think of it is the exhaust fan will rob the GPUs of the cool air that should be pushed out the back.
Positive pressure from the front and top (assuming the bottom is covered) will force air out of the back of the case. Removing the PCIE covers will make that flow easier.
The only way to get heat out of a tight situation like that is to simply make the case have more pressure in it than your room does. All the GPU heat will be pushed out of the case if you do that.

RePasting the cards will help and so will reducing voltage as mentioned above.
