I did a little maintenance on my system just now including applying a fresh layer of TIM, and cut a new 120mm hole in the side.
Well I do have a HAF which is the definition of exemplary airflow with the down side of it collecting dust like you wouldn't believe. Since I was bored and curious I decided to re-arrange the hsf to go front to back. I pretty much re-built the whole computer since I had to take out the mobo to get to the mounting because the hole in the mobo try doesnt line up with my mobo's cpu mounting. Cleaned out all the dust, replaced thermal paste on the NB and cleaned up some wires while I was at it. So far temps are still the same or even a little higher now but since I'm using as5 I will probably see a little drop after it goes through its curing phase.
As for your rig I definitely wouldn't be comfortable having the hot air from the cpu blow into my psu. Also, from my own testing, a single fan pulling always performs worse than the same fan pushing. This was true on both my H50 and the 212+. Why don't you have yours going front to back? Also try taping the gap between fan and hs, it dropped my temps another 3c. I did mine about a year ago and thought I was clever, now I see everyone taping theirs
