Design and Functionality

At first glance Scythe NINJA 2 heatsink didn’t rally change compared with the predecessors. It is the same tower-heatsink, although, this time it has grown a little bigger. It measures 116 x 116 x 152mm and weighs 705g:

The heatsink is built on six copper heatpipes 6mm in diameter that go through the cooler base in two rows. The heatsink array consists of 27 aluminum plates, which is 4 plates more than the first and copper revisions had. Each plate is ~0.35mm thick and is placed at a 4mm distance from the next plate. There is an aluminum heatsink installed at the bottom of the cooler right above the heatpipes:

The plates are shaped differently. Now there is a square hole in the center of the heatsink instead of a round one, and there are no diagonal slits any more:

Looks like this - together with a few extra plates - is how Scythe engineers managed to increase the heat dissipating surface of the new NINJA 2 cooler and thus improve its cooling efficiency. Moreover, the heatpipes in Scythe NINJA 2 heatsink are spaced out at a bigger distance from one another, just like in NINJA Copper model:

This way they can distribute the heat flow more evenly over the aluminum heatsink plates.
