Introduction, Specifications, and Pricing

Even though we have tested many of the Be Quiet coolers in years gone by, on various test systems, it is now time to see how well they do against coolers on the newest system, finally. With what we hav3e seen in the past, we expect certain things from the cooler we are about to see.


Build quality is top-notch, putting Be Quiet in with a select few coolers out there with the likes of Noctua, Phanteks, and Thermalright. Usability had issues in the past with specific motherboards in the past, but this is something that has been addressed, and with a name like Be Quiet, noise is something we should not be dealing with from their coolers.

The Dark Rock Pro series of coolers have been around for quite some time, and is the answer to the Noctua NH-D15/15, being a dual-tower CPU air cooler. Along the way, Be Quiet has made minor changes. Things like the hardware, size of the cooler, fans, and even the coating technologies have all been studied, and the best options of the time applied to the cooler.

Specifically to the latest iteration of the Dark Rock Pro cooler, it also comes with a 250W TDP, and there is also a TR4 variation. Be Quiet are still using Silent Wings PWM fans in varying sizes to reduce the volume of the cooler as much as possible. So, while the Cooler will eat up most of the real estate at the top half of the motherboard, with a lack of noise and the all-black look we have liked for years, it is difficult not to stop and admire what Be Quiet is offering.

At this time, we are speaking of the Dark Rock Pro 4, the latest multi-tower cooler from Be Quiet. What we are about to see is a cooler that is the current pinnacle of what this series of coolers can do. Even though we know these coolers are built to high expectations and lack the noise of many other cooling options on the market, we are still going to take a close look at what the Dark Rock Pro 4 is all about. Putting it through the testing, and mulling over the results before we get excited, yet it is hard, based on aesthetics and ease of mounting, not to admire what Be Quiet has done with this cooler.


Grabbing the specifications from the site, we have a lot of information to go over, starting with the general data section. Here we find the Dark Rock Pro 4 name, and the overall 145.7mm long, 136mm wide, 162.8mm tall, and the 1.13kg weight dimensions. It is also where the 250W TDP is listed, as well as the compatibility. On the Intel side of the fence, it will fit any LGA115X sockets, LGA1366, LGA2011, and V3, as well as LGA2066. On the AMD side, it will fit all of the AM and FM sockets, but if you want it to go with a TR system, there is another specific model for that application. We then see the use of Silent Wings 3 fans, that fans are removable, and even the dB(A) ratings of the fans from in-house testing.

Moving to the heat sink section, we see that the cooler is not as wide as the 135mm fan, and is why the length dimension is reduced here. There are ninety aluminum fins stacked on the heat pipes. The base material is copper, which has been machined and then nickel plated. Taking the heat load from the base of the cooler into the fins are seven heat pipes, all of which are 6mm in diameter, and are again made of copper. As for the coloration of the tower, rather than opting for anodization, this time all of the fins and the heat pipes have been covered with black ceramic spray paint.

To find out what sort of cooling potential is to be had, venture to the fan specifications. We find there that there are a 120mm fans and a 135mm fan. The larger fan rides between the towers, while the smaller of them pushes air through the front, yet offers more room under it for RAM. The 120mm fans will run at a maximum speed of 1500 RPM, on a fluid dynamic bearing, powered with a six-pole motor.

The 135mm fan will spin at 1200 RMP using the same style of motor and bearing, what we see following these numbers are the power requirements, that they both are 4-pin PWM controlled, and that they should last 300,000 hours. As to the airflow and pressure, we can find specifications in the 50 CFM and 1.79 mmH2O range for the 120mm fan, but as to the 135mm fan, they do not sell it individually, so we have no information on hand for it.

Locating the Dark Rock Pro 4 is relatively easy to do at the major e-tailers out there, and when found, we see the cost is the same across the board. Both Amazon and Newegg are asking $89.90, and come with free shipping to members. This is cheaper than many AIOs on the market currently, which is a good thing, but the flip side has shown us some impressive sub $50 coolers to compete with the Dark Rock Pro 4 as well. While we will be going over features, changes, and what the DRP 4 brings to the table, it is the charts that will tell the tale, and as such, we hold our tongues at this time.
