It all fans blow in, no hot air can leave...
you dont need fan's to exhaust your case. you can play with the balance of fans to controll dust build up. simple. There are two basic set ups, one you set the fans so you have more air being fed into the case than you are pulling out. This will lower
your computers dust intake. the other basic combo is to have more exhaust than intake, this turn's your PC in to a giant bagless vaccume, sucking all kinds of bits,pices,dirt,link,dust,fanily pets, small kids,yata yata. it all depends on what fans your using, what case your using, fan placement,and the innards of your computer as to weather positive or negitive is better. For my system I'm not using any fans to exhaust, what fans i'm using are intake only and it yeilds better load temps than any other set up thus far. tons of crap to dictate witch set up is best for you, dont worry to just grab a fan and flip it around, or move it out of the PC to see what works, each system is different
best of luck keeping you gizmo cool
