I don't have the cooler you mention, but from what I read, you can pull the air out the back like you want. I don't know what the cost to performance would be though. It seems that you might gain a degree or two, but that is speculation.
I also think that pointing the cooler up will also gain a degree or two as well. This depends on your case, of course, but most cases favor front to back, even with a top exhaust. I accidentally put my cooler facing up once, and decided to try it out. I have a top exhaust and everything. I gained a few degrees compared to front to back.
