[SOLVED] Fractal Design Focus G Mini Case fans

[mikaspetr612]

I have a fractal design FOCUS g mini and i am thinking about adding an extra fan in The back. Is it a wise desicion to add it or should i add more or keep The two front ones

I would put one in the back as exhaust and keep the two in the front, that should be more then enough for a good airflow in the system.
