Ive looked around and ive learned a little bit about positive pressure and negative pressure and what not, but maybe someone here with a similar build can shine a little light for me.

LINK: Heres my case fan set up .

A) is a negative pressure set up..
B) is a positive pressure setup
C) and D) are similar, except C pulls heat from over the CPU/Heatsink and D) blows air onto it, and exhausts to the right.
.If i have the option, should the HYPER 212 fan point to the back exhaust or should i point it to the top? I do plan on overclocking a least a little bit. IF i can maintain decent temps, id like to OC the GPU too. So any thoughts?

fractal design core 3000 tower
amd fx 6300
hyper 212 EVO
m5a97 2.0 m/b
8 GB ddr3 1600mhz
asus radeon hd 7870 1.0Ghz core, 2 gb ddr5

hmmm...how about moving one of those 140mm top fans to the side panel? on my case the side panel fan will blow directly onto the back of the mobo where the cpu would be. I like the idea of more intake fans, because in principle, the back fan will be more efficient in moving heat out? if this is the choice i make, would buying a higher quality fan for exhaust be a worthy investment?

if i went with B) i would probably make the CPU fan pull on the other side directly into the back exaust (Good idea?) my only real fear is the top vents have no filters...does this mean i should use them as exhaust? or should i make a makeshift filter? or can i just dust regularly inside my case and not worry

No need to worry for the Dust. Components are made to get dusty. Just clean your pc every 2-3 mouths with compressed air. Dont worry for fan spining direction, air from top will not make it spin in other side becouse i youse almost same case like you whitch has 2x 120 mm fans on top and they are putting in air from top on my Coolermaster 612 :)

i think youre right about this, at first i thought about rising heated air conflicting with the top fans pushing it down..but then i thought worst case it will create a heat pocket of some sort? but with 2 intake fans in the front, i think the heat will find its way out the back corner, but then i worry, since theres not anywhere else for the heat to escape from...are C and D bad ideas? with 2 fans by eachother going opposite directions?
