I just put together my new build in a Coolermaster CM Storm Scout 2 case.

Specs:
AMD FX 8350 (watercooled w/ AMD FX block/radiator with 2 fans)
MSI 970A-G46
Geil EVO Veloce 1866 DDR3 16GB
Visiontek 7850 2GB (OC to 1000mhz GPU/1245mhz RAM)
Seagate Momentus 750 GB Hybrid HD
Thermaltake TR2 700watt PSU

My question is how many 120mm case fans would you recommend, and in what configuration? I am prepared to buy 4 if necessary. Thanks!

if you want a dirty computer that's one way to do it.

Generally you want "possitive pressure" meaning more intake then exhaust in your case if you want to keep the internals cleaner. negative pressure cases tend to suck dust into the system like a vacuum cleaner. No amount of lint screens will help either... as the dust will be sucked through any opening in the case, and most cracks and openings are not "dust" screened.

that said, you want airflow to flow from the bottom front to the top back of the case.

So the would 3 intakes (1 front, 2 side) and 2 exhausts (top) e good then? Won't that produce a lot of noise?

not with good fans. Noctua fans are so quiet you hear wind blowing, but no fan noise. There are definitely ways to make a number of fans quiet... that said the utility of those options are questionable because chances are your CPU/PSU and especially your GPU are all far louder than any number of cheap case fans you stick in there.

personally i don't like side fans unless you have mosfet heatsinks that need wind blowing on them... as they tend to break up the lower front to upper back airflow in the case. the few times i've used them i've put fans inside the case itself to keep the airflow flowing in the direction i wanted.

looking to get a new case and doing some research i came across this thread; Question:

if i have more air sucking into the case than blowing out, wouldnt that mean i would have more dust sucking in and not as much blowing out?

i guess i am thinking very simply. no matter what the intakes will bring in dust, but a stronger exhaust force would suck and blow the dust out, wouldn't it?

It seems like most cases come stock with more intake fans setup then exhaust fans, at least the cooler master storm scout 2 i am looking at has 2 intake and 1 exhaust
do you have any links of tests of this, for reference?

Have seen a number of discussions of negative and positive pressure that tend to assume the fans are running full-tilt. Wanted to add a non-expert perspective to the mix. Am setting up the Storm Enforcer with a very common config of 200mm intake and two fans out 120mm in the rear and 200mm on top. The CPU cooler and exhaust fans I have plugged into the motherboard and the front fan directly to the PS via Molex. This way the front fan runs continuously and the exhaust fans slowly or not at all; despite the noise I prefer the comfort of regular airflow. The result is under normal operating conditions (98% of use), I have positive pressure and do not get dust buildup, but when load demands, the exhaust fans tilt and we have negative pressure and good cooling. What I like about negative pressure under load is that the MB can keep speeding up the fans until it gets the air it wants to some extent. Pulling a little dust 2% of the time should not cause untenable problems. Is this sound logic?

the point is you can control the intake point. With a positive pressure case (more intake then out) you can get dust screens on the intake points to keep dust out. With a negative pressure case, dust gets sucked into every opening; the effect is quite amazing to watch. i tried it with my antec 902, and needed to dust the inside the case every 2 weeks. dust was everywhere. when that case is set up for positive airflow, the dust filters need cleaning every 2 weeks and i can skip the interior cleaning once every 5 or 6 weeks.

that makes more sense;

so if there is a "suction" in the case (more exhaust then intake), dust will start to suck in from open vents, cracks, ports... but if there is a stronger suction/intake, then i can control where the air/dust is getting sucked in from and filter those areas!

so the only other option is saran wrap my entire case and poke holes where my fans are lol.

i say that jokingly but i kinda did that with my antec 900. the antec has 2 fans in the front, but the leds were too bright when downloading over night (computer is near the head of my bed).

so i unplugged the front (top) fan, i removed the front frame, and placed saran wrap over where the front (top) fan is and then put the front frame back on. i was thinking of doing something similar with the side fan vent on the case as well. i figured it would create a better (more direct) air flow if i blocked "intake leaks" , not even thinking it would also help block dust.
