Hey guys! I hope you can help.
So I was cleaning my PC recently, and I noticed that there dust particles that are too big to pass through the filtered fan intake that is on front of my case, not to mention, that I have a 360 mm rad in front, that should act as a filter too. (somewhat) So I did a bit of research about it, found a vid from an unamed youtuber (name starts with a "J") Which is about airflow in your case. And that negative air pressure is the culprit, since it forces air in to unfiltered openings in your case.
So here is my fan lay out.
3x - 120 mm SP fans front
2x - 140 mm stock case fan top
1x -140 mm stock case fan rear
2x - 70 mm AF fans rear
Right away, you can see the ration of the fans will give out a negative pressure. I am not looking at adding fans for intakes. What type should I go for? SP or AF? Not that 3 of them will be mounted at the rad, for a push and pull set up.
Thanks!
