Hello guys.
So I'm planning to purchase a gaming rig, link here:

My question is how many fans do I need for the NZXT S340 case.
It cames with a fan on top and one in the back.
Now, I don't want it to be an overkill but I do want proper cooling, especially in summertime, since I live in Italy and there is a lot of humidity here.

Any advices for me?

So it has these spaces:

Front: 2x 140/2x120mm
Top: 1x 140/120mm (1 x 120mm FN V2 Fans Included)
Rear: 1x 120mm (1 x 120mm FN V2 Fan Included)

I'd suggest filling it up with two more at the front - two front intake, two outtake (top and rear) is nicely balanced.

So I need to get two more to put them in front and a third one to put it in the back (since it already has one in the back). This way I'll have x2 front, x2 back and x1 top.
Is that correct?
 
What ever you use to cool the CPU and GPU does not change the need for 2 case fans at the front, and 1 at the back.

And yes, Noctua fans are amazing. I went with a CM 212 EVO CPU cooler when my Intel cooler fan died at about 8 months, and I wanted more air flowing through the 212 EVO. I put a NF-F12 fan on it, and despite ambient temps climbing as summer arrived, my CPU is still 5 degrees cooler than it was. I'm sure my 3 Noctua case fans have helped as well.
