So you've presently got your CPU cooler running rear to front airflow in that pic. Whereas your rear case fan is exhausting air from inside to out, so front to rear.I noticed when I took this photo the fans were the wrong way round, I misunderstood the triangular direction notches. But saw that it didn't match the installed case fans.
The outer fan just sits a little higher as it rests atop the ram. Vengence LPX which hasn't got a very large heatsink anyway
Derp, understood your phrasing now.
