What that can do is bypass your fan filters (especially if you have unused fan slots/vents) and leave you with a dusty/dirty system sooner than you'd expect.
In short, try to have a positive case pressure using combinations of CFM, placement/direction and rpm (fan controllers are nice!)

Good Luck!
What is CFM? I have 5 fans all together...one blowing out in back, one blowing in from the front, one in side blowing in, one in the bottom blowing in, and one in top blowing out.

Cubic Feet per Minute. A meausre used to describe how much air a fan (or other devices) can move. Notice the CFM listed on all these fans here? Hopefully that makes more sense now

@ Case1

Just add two top exhaust fans and your good to go [2 x intake (front/side) plus 3 x exhaust (top/back)].

IMO, swapping the side fan to the bottom as an intake would be better but could result with more dust entering the case if there's no fan filter. Having both side and bottom fan would disrupt airflow, it's better to have just one of the two (side or bottom) while keeping two on top as exhaust.

These are great Zalman fans: ::: Zalman, leading the world of Quiet Computing Solutions :::

Just make sure you get a few of these to go with them to run them in 5v: ::: Zalman, leading the world of Quiet Computing Solutions :::

For my setup at least, I found having the top 200mm fan as intake lowered temps more than having it as exhaust. I have 2 x 200mm front (bottom) intake, 2 x 140mm front (in the 5 1/4 bays) intake, 140mm bottom intake, 200mm side intake, 200mm top intake. I have the 2 x TY-140s on my Silver Arrow blowing out the back through a 140mm Ultra Kaze 3000 exhaust.

Not the quietest setup but I don't mind a little noise; I like things cool.
