I am currently stuck in an odd situation where my CPU fan can only be installed on one side of my cooler due to ram issues (I've got a Hyper 212 EVO), and it is currently fighting my rear exhaust fan by pulling the air from the back of the case and blowing it through the fins. I am curious to know if I flip the fan, but keep it on the same side (it would be pulling air from the other side of the cooler through the fins) if it were to cause a problem when it comes to cooling, or if it will cool just as well.
