Currently I have one intake fan on the front and side (blowing on the video and pci cards) of my case, and one outake fan on the back plus the powersupply fan. I would like to put another fan on the inside of my case without, a blow hole, to blow on my cpu. Will this cause a temputure problem since air from inside the case is being blown on the cpu, instead of fresh air from outside. I don't want to put another blow hole for the cpu fan because then i would have 3 fans blowing air in(front, side, cpu side} and only 2 blowing out(power supply fan, back fan). Any thoughts.
