be quiet! Dark Rock Pro 2 CPU Cooler
From the front it seems the 120mm SilentWings fan selected to act as the main intake is a bit undersized. Compared to the 135mm on the Dark Rock 2, this doesn't seem to cover the fins near as well.
Looking from the side I see it was used to leave more room for the memory since the dual-tower design will use up a lot of room around the CPU socket region. After the first tower and before the second, a 135mm SilentWings fan is used to give air an extra push as it makes its way through both stacks of fins.
The exit side of the Dark Rock Pro 2 is flat and pretty plain. So instead I would rather point out that without a bit of creativity, you can't add a third fan; and did you get a look at all of those heat pipes?
The top has a similar cover to the Dark Rock 2, just this time it is slightly larger and has a different offset for the caps that cover where the seven heat pipes pass through each tower. As you can see they help keep the air in the middle of the cooler with the chevron pattern of the pipe layout.
The safety sticker is blocking the view a bit to actually see the solder bits as the pipes leave the base, but you can see that each fin uses a pressed on fit to secure the fins to the pipes.
The base is very flat and so smooth that I couldn't pick up on any milling marks. In fact the base on the Dark Rock Pro 2 seen here is much more level across the entire surface with very minimal deviation towards the extreme edge of this base. We saw a little deviation with the Dark Rock 2, but not here.
There is definitely some more hardware available to use with this cooler, but for my purposes I went ahead and installed the LGA1155/1156 brackets so that I am ready for the next stages of installation. Everything but the screwdriver is provided in the hardware kit to fit even some very old sockets right on up to the latest FM1 and LGA2011 motherboards.
With the fan removed you can see that the saw-toothed pattern isn't lost in this design. While the cut into the fins may not be as deep in the middle as we saw with the Dark Rock 2, both towers have this cut and any bit helps to disturb the air and make the air passing through pick up more heat.
