I have one fan on the upper half of my case in the back about an inch down from the power supply, now my question is: should this be intake or outtake? The powersupply is outtake and I was wondering if I needed some sort of intake, but I was worried becasue the fans are near each other and I thought having the one fan be in take with the powersupply being outtake would essentially cause them to cancel each other out. What do I do?
