Right according to my (poor) memory,I have 2 AP120's (they are all Corsair Silent AP 120's,I know,I should have got some AF 120's,but the AP's were on offer!) in the front,sucking air in,one in the bottom sucking in,the XFX (SeaSonic) black edition,modular PSU (750-850w),which has an option to only turn the PSU fan on when needed (that is on),4 pumping air from the case,out through the watercooler (Corsair H100),and one more in the back,pushing air out...So that would be 3-4 pushing air in,and 5 sucking air out...
