[SOLVED] Fan Cooling tips

[itz_artemis]

I have in my Corsair 400 case a H100i Radiator with 2 noctua 120m fans pulling air , 2 noctua 120m fans on the top, and one 120m noctua fan on the back. The radiator is placed in the front of the case and the 2 fans are pulling air thru the RAD into the case, the two top fans are pulling air downward int
o the case, and I have the back fan as an exhaust fan pulling air out of the case. My general question, is this fan set up optimal or should I change them around. Thank you all for the help

I realized that I also need to look into static pressure vs airflow. Currently all of my fans are Noctua NF-F12. So I would also appreciate the help in which noctua fan line I should use for the radiator and air flow. Static pressure vs air flow is confusing me and im unsure why a NF-F12 wouldnt suffice as an option of the radiator

Too much air in and too little out,
High static pressure fans are mostly used for radiators when they are set to blow thru it. Reason being is that radiators present more resistance to air because of small openings in it and need more pressure
For case fans higher flow is better as you need to push thru as much air as possible with least number of fans. Too many fans place improperly can be worse than too few properly used.
If you want Noctua fans, they make both types that look same, only difference is in fan fins shape.

Are these the correct case fans I would use
Noctua NF-A12x25 PWM

Also, how would you recommend to have fan placement set up. I was kind of coming to the conclusion that one exhaust fan in the back wont take out enough of the air coming into the fan

Radiator fans count as about 90% of air flow for the case comparing to case fans in same configuration. That fan is good for either application so no problem using them.
Your rad fans are placed OK but top ones need to be reversed so they blow out. If they are set as intake they would interfere with flow thru radiator because of too much pressure in the case.
Air low is is primary concern, positive or negative case pressure is much less important. Some say that positive pressure in the case helps with dust collection but I have never seen that effect.
