You are throwing good money after bad basing cooling upgrades on the Asus cpu measurment from that motherboard. Here are some comments from me regarding exact same mobo and its temperature readings about a year ago:
"Of course it is hard to know how effective that this method of cooling ever was since in-socket probes are notorious for being cooled by secondary methods. You can see in the individual test graphs that not only was the Asus socket probe incorrect in absolute terms, it was not even able to reproduce the proper order for the coolers performance. To further complicate things for the end user, it tends to underreport temperatures when cooling solutions are not performing well, and overreport temperaratures when the cooling is performing well. This is due to the approach that Asus has taken (a probe with a high temperature compression combined with a 10-11C offset to correct for this). The end result is that people who spend lots of money on cooling and tweaking may needlessly mess with their setup trying to figure out why it isn't performing up to par, while people with dangerously inadequate cooling may have a false sense of security. All around it is pretty much worthless."

Just went and looked at my Maze3; there is indeed a "short side" and a "long side" wrt the mounting holes location to the edge. You should probably mount it so that the short side is the one facing the raised part of ZIF socket. I don't have it mounted at this time, so I can't tell whether mounting it the opposite way would catch the raised part of the socket though.
