Side Case Fan

I'm in an odd predicament right now. I used to have my side fan blowing air into the case, which brought down the temperature of the case. I realized that my CPU temperature was quite low, but my video card took very long to cool down. When I opened my case, I noticed a lot of the hot air stayed in the case, leaving my video card constantly warmer than what it should be. I decided to switch the position of the fan, so that it blows air out. My video card temps were much, much lower (my 7900GTO idols at 33-34 degrees Celsius), but my CPU now idols at 43-45 degrees, as compared to the 37-39 degrees when the fan was blowing in.

This being said, I have a fairly cheap case. It has support for a side fan and a rear fan, but it seems as though I can't put an 80 or 120 mm fan in the front of the case. Before I open my case, I was wondering if perhaps I should set my back fan to blow inside the case, while the side fan blows out the air. Would this work with success?
 
Well, as most people will say, you need to have one blowing in, and the other blowing out. If your case doesn't support ANY front / intake fans, I'd replace the case. If you're up for it, you could probably mod the side and top of the case to use 1 or more 120mm fans which would increase airflow. My recent project is going to have 4 120mm fans sucking air from the side, 2x80mm fans in the rear to exhaust by the cpu, and 1x120mm fan at the top of the case exhaust air out the top, and 1x120mm fan to exhaust air in front of the hard drives.

Good luck
 
no it won't if you have a normal ATX setup.
Your PSU blows air out, and having the back fan blow air in will only cause that warm air from the PSU to be recycled back onto your heatsink.

If the PCI slots under the gfx card are empty, simply remove the slot covers and tie a 120mm fan to exhaust that hot air out of the case.
