I finally came to the conclusion that I need to add a case fan to my current PC. The fans on the CPU, GPU, and power supply aren't just cutting (for my liking actually). My main question is about the size of the fan. I have a big case (can hold 3 graphics card, multiple drives, and still have room for fans) so should I be looking at 120mm or 140mm fans?

I'm guessing that the 120mm fans will move less air than the 140mm fans, but the 140mm fans will be louder than the 120mm. Is the difference that noticeable in the system?

Finally, what about getting 2 fans? I understand that an intake fan and an outtake fan is optimal. However, should I just start with an outtake fan then add in an internal fan later or just get both now?
