goes in one ear and out the other... but more in or more out?

wow that was a crappy subject. But really, i have heard many conflicting views... should I have more air coming into my case or more air going out of it. From what I have heard people like a negative pressure because positive pressure creates heat in itself. I have heard people like positive pressure because it keeps dust out. I dont know if either of these are right or what is right... so anybody please chime in with your view and your reasoning.

I don't have a definitive answer for you. But, how does this sound: try to reach a near equilibrium with almost as much air going as going out. You'll never be able to get it to be completely equal, but this is not rocket science and if you get it close enough it should work fine.

i've always read more in is better than more out. i did my mod yesterday and i got a 5C drop on my load temp! that's after running prime95 for 2 hours. that's pretty good i would think... i used to get 39-40C under load, but now i never go over 34C, so i'm happy with my mod.

i have one 120mm panaflo 68cfm going in and one going out. the front hole is completely cut out but the exhaust is not cut. i just put the fan where they have the pre-punched holes. so i have more going in than out.

Most will tell you to slight overpressure your case with more in. Look at the amount of airflow restrictions where you mount your fans. Direct blowholes on the intake & chrome grills on the exhuast will reduce total restrictions & improve air movement through the case
