I think Illuminatri is probably right but another possibility is that the "good" side is the side facing the fan. If this is true you could try increasing the "Minimal layer time" from 7 seconds to maybe 10 seconds but I have found 5 seconds is usually plenty.

I suspect that it's a problem in the slicing itself - your settings look sane, and the minimum layer time of 7s should be giving long enough for it to cool between layers. I think that probably the head is backtracking to start the new layer, and its causing problems. This can happen with shapes like this, where the print segments are long, but the corners precess around the shape.
Older versions of Cura had problems with this and would keep trying to move back to the vertex nearest the origin to start the next layer.. that may be what is happening here too. When the head moves back, it drags back over the print, oozing, and making a mess.
Can you post the gcode here as an attachment, or email it to me at gcode@fbrc8.com, and I'll take a look to see what's happening?
