I just bought 4 Scythe S-Flex 120mm Fans. I was planing on installing all 4 on the door of my case. That would leave me with 5 intake and 1 exhaust out the back. I have room for 1 more fan on the top but was just gonna leave it empty b/c heat rises. Does anyone have a similar setup? Do you think that would be too much intake? I don't know much about the whole cooling thing.
