Ninja Copper: Scythe's 5th Year Celebration

These photos show the steps to installing the NinjaCU on a socket 775 board.

Step 1: CPU support plate goes beneath the CPU socket of the motherboard. Screws go in from the bottom. (Note: We used a similar plate from another Scythe heatsink mounting kit.)

Step 2: The screws from the bottom go into the two bars on top. (Note: There's a touch too much TIM on the CPU in this pic.)

Step 3: Flip the NinjaCU over and...

...mount the 478/775 clip with four screws. (The screws have not been inserted yet). Note that the clip can be rotated 90 degrees if so desired, mainly to keep the fins on the small aluminum fins at the base in line with fan airflow.

Step 4: Secure the heatsink to the four mounting points. This is a two step process. First, two ends of the clips hook from underneath; the other two ends clip from above. A fair amount of tension must be applied for step two. Don't have RAM installed when you do this; you may also require a pair of small needle-nose pliers.

On our 775 board, clearance was quite tight. The rim of the clip around the base just barely cleared the small capacitors around the socket. In the last photo above, the capacitors appear to be touching the heatsink. They are not, however. The clearance is probably about a millimeter.

The hooks look pretty short.

Although the tension on the clips is high, the hooks on the tabbed ends don't seem as long as they could be. One has to assume they've been tested on a vertically mounted motherboard in a typical midtower case, but it's not really that confidence-inspiring. This is a two-part mounting system, and in the end, we're still relying on a pair of steel clips to hold up over a kilogram of cantilevered mass.
