A cooler this large is going to put some stress on your motherboard. The mounting hardware included seems like it is up to tackle this job, but are you? A cooler of this size must be a little difficult to maneuver inside a case. I will be installing it in an open air test bench like setup.

Step 1: Steps 1 and 2 are interchangeable. I chose to first attach the mounting clips to the heatsink itself. This is done rather simply with 4 screws. If you would like to mount the Orochi in a certain manner for a specific orientation in your case, the bracket may be applied whichever way you like.

Step 2: Attach the mounting bracket and backplate to the motherboard. Again, fairly straight forward. Since this cooler will only be used for testing purposes and will be removed shortly, I chose not stick the backplate to the motherboard as they are almost impossible to remove. If you have the same mindset, it makes installation a little more difficult as you must hold the backplate on the back of the motherboard, hold the clips on the front of the motherboard with plastic washers underneath, and screw them together from the back of the motherboard. I usually recommend that manufacturers stay away from separate plastic washers and have them pre-applied to the mounting bracket to save some hassle.

Step 3: Apply thermal paste and attach the heatsink. First, hook one side of the heatsink (as seen on the left) into the latches on the mounting bracket. Then, lower the heatsink until the clips on the other side can be properly positioned and hooked on to the mounting bracket.

That would be it for the installation of the Orochi, as you can see it makes my ATX board look like an mATX board with its sheer size.
