FYI, higher static pressure = lower airflow (given the same fans).
If you have two front fans, and you add two identical spec'd exhaust fans, you have more airflow due to lower static pressure in the case.
Depending on case design, you may be better off with different setups, but the laws of physics still apply.

Here's another chenming case (mine):
same basic setup - 2 80mm exhaust, 2 80mm intake, psu exhaust, and two 80mm rad fans up top. That setup (and a 50% setting on the GPU) keeps my cpu and my GPU at or under 55C, with the fans all on quiet mode.
The taller chenming allows for two (or three if you didn't get the koolance one as the pumps went there) 80mm front fans (one per each harddrive cage), two 80mm exhaust, PSU exhaust, and a 92mm exhaust up top, at least mine does but the PSU isn't in sideways - they had different backplates up there)
