Hi everyone. I got 4 case fans + cpu cooler fan in my Corsair 100R case.
Fan 1, 2 and 4 are 120mm running @ 8-900 rpm
Fan nr. 3 is a 120mm running @ 1200 rpm
Now, I've noticed air leaks into the case from the unused vent hole nr. 5
Is this good? Should I close it with some tape or maybe move fan nr. 1 to vent hole nr. 5? I was undecided whether to put a fan right above cpu heatsink or top middle...
