Little help with case fans please?

[Mihael_7]

So, i've bought NZXT S340, it has 2 case fans, one on the rear and another one at the top, do i need anymore fans than that?

What is the difference in temperatures with those 2 and more?

If i'm buying more, how will i connect it to PSU if it has limited amounts of male molex cables?

EDIT: This is my first time building a PC.

What hardware do you have, and what are your priorities for this build?


Regarding hardware, please include the motherboard, CPU, GPU, PSU, any aftermarket coolers, hard drives, SSDs, etc.

Priorities may include:
Reliability, Maximum Overclock, Noise Levels, Gaming Performance, etc.

Remove the top fan and mount it in the front of the case blowing in.
That should be enough cooling unless your PC is going to be in the 400 Watt area under load.
Depending on the fan and motherboard they can be plugged into the motherboard or PSU
