So yeah, airflow may not be the hardest thing ever, it's just physics but I still want to make sure I don't fluff this up :D

My case is an NZXT Phantom 410 and I want to replace the two stock fans, and add more fans to get the best cooling possible. My idea was this:

YOUR BASKET
3 x Akasa AK-FN062 Apache Black Super Silent 140mm Fan - 4 Pin PWM £14.99 (£44.97)
3 x Scythe Gentle Typhoon 120mm 1850 RPM - 3 Pin £14.98 (£44.94)
Total : £89.89 (includes shipping : FREE).



I was thinking of setting it up like this:

My Alpenfohn cooler is using the stock fans, and they're currently blowing towards the extraction fan (and is doing a mighty fine job!)

Any help is appreciated. Thanks! :D

I would run 2 front and 1 bottom in with 1 back top and 1 back exhausts. Let the front top vent just let air out as needed. This will give you positive airflow and not suck dust in except though intake fans which I assume you will have filters on.

Raising your case up so it has 50mm gap between case and floor/desk will mean your bottom fans have unrestricted airflow. As it is the case make the bottom fans try to suck air though from a surface area about 1/3 of the surface area of the fan.

I have my case exactly like this and it's very cool inside.
 
Awesome thanks for clarifying guys!

I won't be getting an intake fan on the bottom, I don't want my computer propped up but it's a good suggestion. Added some fan filters to the list also :D

As long as you have a filters on all the fans you should be fine on whatever set you do.
 
Ideally you want more fan cfm in than out so the intake fans are pushing air out of case. If exhaust fans are pulling harder than intakes are pushing than air will be sucked in through all the holes, seams, cracks, optical drive, etc. and pull dust in though them... and dust then collects on all of these leaks too. If intake fans are pushing more air in the opposite happens and dust only collects on filters.
 
The Scythe Gentle Typhoons have good static pressure and so are good for radiators and heatsinks, however I'm not sure I'd pick them for case fans.
Higher CFM fans with a lower dB would probably be preferable for case fans. Well, they would be if I was doing it...
 
CFM vs static pressure is a double edged sword. Fans by their very nature create static pressure in order to create airflow. If there is no pressure differential there is no airflow. Higher pressure air displaces lower pressure air. Radiators and heatsinks resist airflow more than other components in case do but filters, grilles, HDD cages, GPUs, cabling are all resistance to flow of air... and static pressure to required to overcome this resistance. Some reports say a normal mesh grille will restrict 20% or more and similar reports for filters. Of course the higher the static pressure of the fan the less filter and vent grilles will restrict the airflow. And of course the more restriction there is the louder the fans will be.

Myself I use Thermalright TY-140 fans (1.89 H2O / 74cfm / 21dBA) for case and TY-143 fans for cooler (?.?? H2O / 130cfm / 45dBA) Same fan with faster motor; 1200rpm more maximum rpm so H2O is probably 3.?? H2O

At same speeds both make the same static pressure, cfm and dBA. At 660-750rpm without filter/grille I can't hear them. With filter/grille I can hear them at 40cm. At 900rpm they are audible at 2 meters. Stress testing they run 1150rpm and can just be heard at 3 meters.. and all my fans run the same speeds.
 
Will this set up be adequate cooling a GTX670 Windforce SLI set up? I know the Windforce cards like to recycle air, hence I want decent cooling to overcome this when I buy the second card.
