be quiet. Dark Rock Pro 4 CPU Cooler


At the front of the Dark Rock Pro 4, the view is mostly of the Silent Wings 3 120mm fan, which covers the fin stack from top to bottom, but has a bit of width lacking in coverage. Below the fins and the fan, there are seven heat pipes, but two are bent in behind another pair, making them difficult to see at this angle.


From the side, our view is of, from left to right, a 120mm fan, a ninety-fin tower, the 135mm fan, and another ninety-fin tower, and all but the front fan covered with a thick layer of aluminum at the top. At the bottom, we get a better idea of the bends of the heat pipes, and can now see how seven pipes are used.


Looking at the back of the cooler, not only do we see the fin stack, but we also see that the fins are shaped differently in sections, and is found on the leading edges as well. Doing this to a set of fins allows the fans to spool more pressure in specific areas, to "boost" the ability of the lower CFM fans cooling them.


As we gander at the left side of the cooler, we see a mirror image of what we found on the right side. Covering much of what is there from the other side, we will address the fan heights now. The 135mm fan sits low in the cooler and covers the majority of the fins, both pulling through the front stack, and pushing through the second. As for the front fan, it is smaller, so that, along with the notch in the first three fins, allows for better RAM clearance.


The top of the cooler is made of aluminum, it has been brushed, and is anodized black. The "be quiet." name in the center pops, and we also see sixteen caps, but only fourteen of them cover heat pipe tips. The two on either side of the nameplate are removable and are used as access holes for mounting the cooler.


The base of the cooler is made of two parts and different metals. The top section, which is a pre-cooler as well as where the cross-bar mounting takes place, is made of aluminum. The lower section is made of copper and is what transfers the heat from the CPU to the heat pipes.


The view of the bottom of the cooler shows us a few things. It is easier to see all seven of the 6mm heat pipes now, and following them to the finds shows that dimples are used in the fin stack, which helps with efficiency. Lastly, we can see the nickel plated base, which is currently protected with a plastic sticker.


With the protective cover removed, we find that the base is machined quite well, with just the faintest hint of a circular pattern found. As many are, this base is also higher in the middle, which helps with mounting pressure, which in turn helps with efficiency.
