Hello everybody, I'm building a new system in a couple of weeks and have opted for the Corsair Air 540 case. I have a few questions about my planned fan configuration and I'd appreciate any advice you guys could give.

Basically, my plan is to cool my CPU using a Corsair H100i with a push/pull configuration coming into my case from the top mounting position. I plan on using two Corsair Air Series SP120 High Performance Edition High Static Pressure 120mm fans on the top and bottom of my radiator.

I will be exhausting air from the back of the case using an Air Series AF140 Quiet Edition High Airflow 140mm Fan.

On the front of the case I am deciding whether to use three of the aforementioned 120mm fans or two of the 140mm fans. I plan to intake air through the front.

I'm pretty new to this whole thing, and air optimization is feeling like a daunting task. My main concerns are the air pressure inside the case, considering I would be drawing air from the top in a push/pull configuration and from the front and exhausting it out of the rear fan. Would this cause any issues?

Would it be better mounting three 120mm fans on the front or two 140mm fans?

Also the fans I have chosen are a concern as I'm generally unsure on case fans and I'm sure this is just a case of classic overthinking. But as they say, better safe than sorry!

Honestly, when I make a system, I NEVER buy fans for it when I first build the system. I use the stock fans on the case for a couple weeks, then IF im not getting the temps I want, or the noise levels I want, I change them out.

Trust me, use the 3 included fans with the case first before buying more. Also, leave them where they are already mounted.

I would do the same with the h100i.


Regarding the flow, the classical setup is intake from the front, and exhaust from the back and top. Try that out first.

Okay, I'll take your advice and leave the fans as they are for now.

And if I do decide to make the changes then I'll try that setup.

Thanks a bunch :)

Just quickly, could I ask the reason for this? Just for future reference.

The reason for that classical setup is because hot air rises. You want to take advantage of that, buy going with the natural flow of the hot air.

E.g if you intake from the top, you would be pushing back the hot air that is trying to naturally rise up. this causes turbulence inside your case. However, this effect is not as dramatic as it sounds. It makes little difference in temps, but its best to start out this way, so you always have a point of reference in case you do make changes to your setup. This way you can tell if you improved or degraded the cooling performance of your case, by changing the flow of air.

I would experiment with different setups once you make your system and see what works for you.
