(I know this has pry been covered before but I couldn't find it.) I have a standard tower ATX case. Currently it has one fan on the back taking in air which the cpu fan then pulls thru the heatsink. (the cpu is at teh upper right of the mobo when standing up.) Then the power supply has one fan on the bottom taking air out of the case and one at the back blowing out. I am getting four more fans in today. I was going to put one at the front bottom taking in air. One on the side of the case taking in air. (not sure best place to put it. i.e. above video card or processor, or at bottom) One on the top of the case taking air out. And I was thinking the last fan would also go on top. Does this sound good? Should I switch the fan on the back of the pc to take air out? Thanks for the help. P.S. I also have a fan controller to controll the 4 new fans so they won't always be on. Just during high graphics applications and when it is really warm in my room.
