It has two spots on the side to put 120-80mm fans. I have an extra 120mm and many 80mm fans. Is it worth it to add the fans or will I be putting to much positive airflow into the case? I have the following:
140mm on top as exaust
120mm bottom front as intake
2x140mm push/pull as exaust for back radiator
I agree a side fan should blow air into the case. I would highly recommend it if you're water cooling your CPU. I noticed a 15c drop in surface temps from the heatsinks surrounding the CPU when i installed a RAM fan. I'd imagine a side intake would produce a similar effect.
I have a mid tower, and I had to put my fan into the bottom slot on the side. I think there would have been an issue, as fans stick out at least an 1". Also, my GPU has a power cord that goes in on the side rather than opposite the back of the computer. (weird design, and really stupid)
