As for the fastening, a pair of flexible clips are already attached to the cooler, so you only have to put the fastening frame on the mainboard:

The standard mainboard’s frame is used to mount the cooler on Socket 478: just put the processor into the socket, add some thermal paste and close the clips – the whole procedure takes less than a minute of your time!

The Socket 754/939 fastening is more or less acceptable. You install a frame like the one that stands on Socket 478 and snap the cooler up to it.

This cooler is a square – it doesn’t have a shorter and longer side. That’s why the socket orientation on the mainboard plays no role. You can attach a fan to any side of the cooler, directing the air stream anywhere you like.

The LGA775 frame is assembled exactly like for the Scythe Shogun, i.e. slowly and inconveniently.

Fortunately, I tested the Ninja right after the Shogun and didn’t have to repeat that dull procedure. By the way, be careful when you are handling this cooler – the heatsink plates are soft and bend down just too easily, and they also have sharp edges.
