I think you should flip your radiator around so the inlets are facing the pc. The fans, i think, should be sucking air in from inside the case because in the back is where its all hot. Also, if you flip your rad around you wont have that foot or so of tubing sticking out of ur pc to the rad, looks to me like its asking for a little kid to tug on it or a cat to play w/ it.
