BCC Hardware posted a review on the Scythe Ninja Plus HSF

At first glance the Ninja Plus looks like it has 12 heatpipes. In reality there are 6 heatpipes that wrap clear around in a large "U" shape. This give every side of the fins a fair shot at cooling the pipes. Down the center of these fins in a hole that goes all the way down to the bottom. You can see in the picture above and on the left that there are some fins on top of the heatpipes as well. In the picture above and on the right you get a look at all the goodies that come in the package. The Scythe Ninja Plus should mount on Socket 478 motherboards without any of the mounting hardware, but if you run an Athlon 64 system, you'll need to use the black plastic bracket using the motherboards backplate.
