Running a 60mm thick 3x120 rad on either side in the back, with fans in push config for both (psu did not allow for 4x120 rad sadly). One is intake and one exhaust, so it's a straight crossflow of air.
For the front half, I have a 140mm fan on top exhausting and a 140mm fan in the 5.25 bay for intake. This pulls air from the back chamber where the rads are, I have a 140mm case fan under the 3x120 rad to help feed this more air.
Now the top of the back chamber has a 140mm fan opening and the very back panel has 2x140 openings. Is anyone using these? I feel like these would cause issues with the radiator air flow. I have half a dozen spare 140mm case fans and wondering if it's worth while to use these spots, keep them open, or try and seal them?
