2x Top Fans as Exhaust Have no Use?

I have a storm scout 2 case with 4x intake (2x front, 1x hdd, 1x bottom), and 3x exhaust (2x top, 1x rear). I also have a vertically positioned 212x with 2 fans in push-pull.

In spite of having more intake (positive air pressure), I feel like my system is having more of a negative air pressure. I say so, because the 3 exhaust fans have no obstacle, as opposed to my 2 front intake fans which is obstructed by the HDD cage, and the bottom fan intakes the least amount of air. Of the 4 intake fans, only the HDD fan brings in the most air.

I'm thinking of making the two top fans as intake. Is that ok? If I do that, only the rear fan wil act as an exhaust. What can I expect (both good and bad) from having that setup?

yes... dont make the top fans intakes. that would be a problem.

while positive pressure is suggested, negative pressure isnt going to hurt. negative pressure just tends to suck dust into every little nook and cranny of your case.

if you're that worried just disconnect one of the fans on top and use it elsewhere or not at all. or do as pat suggested and get some higher cfm intake fans.

Yes, I think I'll keep it as it is right now. When I'm gaming, the 2x top exhaust fans really help in dissipating internal heat (I feel the warm air going out.) What concerns me the most is when I'm not gaming. Since my rear and 2x top exhaust fans are plugged in directly to the PSU, I have no means of switching it off and it runs at max speed all the time.

As for my 2x front intake fans, I believe I'm already using a high-cfm one. It's a 4-pin, 120mm, 64CFM fan which is optimized for static pressure (which in my opinion, is really necessary to push air through the HDD cage blocking its path.)

That would be a viable option if I'm using a closed-loop liquid cooler. Problem is, I'm air cooling in push/pull config, taking air from the front, through the heatsink, towards the rear exhaust fan.

I can do that, but I have to horizontally-align my 212x, which I'm not quite a fan of.

I've read where supposedly you can get better temps with a heatsink oriented that way, but I'm not sure.

I flipped my heatsink and re-timmed at the same time, so I'm not sure if it was better or worse than before. It did cause RAM heatsink clearance issues, but I digress.
