4. Visual inspection

The Dark Rock 3 model has an attractive design the heatsink being completely black. The cooler is accompanied by a 120mm fan from the SilentWings line, model BQ SIW3-13525-Mf-PWM. The cooler utilizes 6 nickel-plated aluminum heatpipes, each has a 6mm diameter.

The cooler utilizes 51 aluminum fins which are painted black, these fins make direct contact with the heatpipes.

The 6 heatpipes are arranged in a U shape to facilitate heat dissipation, these make contact with the base of the cooler but not direct contact with the CPU itself. Mounted on the base of the cooler we find a small secondary radiator.

Like the heatpipes, the base of the cooler is made out of nickel-plated copper. The base is brushed to a mirror finish.

The top part of the cooler maintains the minimalist look of the cooler, the metal is brushed. In the middle we find the manufacturer’s logo also the caps of the heatpipes are made out of aluminum and painted black.

Software used for testing the cooler:
–    AIDA64 Extreme Version: 5.50.3600 (9/29/2015)
–    Intel Burn Test v2.54
–    Prime95 28.5

The cooler was tested with the CPU at the default turbo frequency of 3.9 GHz and overclocked to 4.5 GHz with a core voltage of 1.187 V.
Also the included fans have been used at their maximum speed.
The room temperature was approximately 26°C (78°F), with 2°C margin of error.
The idle test consists of the CPU sitting idle at the desktop for 30 minutes, the temperature was measured at the end of the test.
The settings of the software used are the following:

Intel Burn Test v2.54 – Stress level: Maximum
Prime95 28.5 – small FFT
AIDA64 Extreme Version – Temperature monitoring.
Each test was conducted for 40 minutes.

The test results are as follows:

Full Loadload

 

The noise level was measured at three different distances from the fans (10cm, 20cm, 30cm.) the noise was measured with a margin of error of ± 5 db.

The space between the DIMM slots and the front fan is approximately 31mm.

6. Final thoughts

The Dark Rock 3 cooler stands out through its exceptional build quality and its low noise when the fan is at its maximum RPM.  The thermal performance is good for a cooler of this size, the Dark Rock 3 model being approximately 7 degrees behind a good AIO cooler.
Another feature of this cooler and the BeQuiet! brand is the attention to details, starting from the base of the cooler which is polished to a mirror finish, the black heatpipes and the included fan.
The main drawback of this cooler is the insufficient space for the RAM memory, at 31mm only memory with low heatsinks will fit under the cooler’s fan, also the fan extends over one RAM slot.
In conclusion, although the price of this cooler is high, it is justified by the exceptional build quality & materials used, and the included fan. The thermal performance is good for a cooler of this size and the included fan is one of the most silent fans.
