After applying the backplate, you slide the mounting bracket through the bottom of the cooler and place it on the notch I showed you earlier. From here you just apply your thermal grease and screw it down. You might be thinking, “Okay, so the screws keep it from going up and down, and the notch keeps it from going right, left, forward, and backward, then what keeps it from rotating?” Yeah, that's what I was thinking, too. Nothing helps with that, you just screw it down so hard that you couldn't move it if you wanted.
As you can see, since there is so much room before the fins start on the heatpipes, there are absolutely no issues with clearance over the surrounding capacitors and memory, etc. You can make the cooler face any direction if you have the room. I aligned mine so that the fan would point directly towards the rear exhaust fan and all hot air would be ushered promptly out of the case.
Here are some pictures of the cooler fully installed. The knob on the fan controller is a little wider than my expansion slot, so I had to pop it off to install it, but that's not a big deal. The blue LED fan is pretty, but you can't really see much of it except on the mounting bracket because the fins block out most of the light. The cooler fits nicely in the case with a few millimeters before it would be too tall to put my side panel on correctly. Awesome, it's in, let's test it out.
