A Closer Look

The Pure Rock doesn't have the same appeal as the Dark Rock 3. You won't find dark nickel plating. To save on cost, you will see regular copper heatpipes and aluminum fins instead.


The single tower design is comprised of four Ø6 mm heatpipes that transfer heat from the copper base to forty-eight aluminum fins. Nothing really new here, but the quality is very good for the price, so here's to hoping performance lives up to expectations.


The top has a solid aluminum top plate with be quiet!'s logo in black. The heatpipes themselves have aluminum caps, which adds to the cooler's quality feel, all while keeping its appearance clean. The heatpipes are, as is typically the case in single-tower designs, arrayed in a U-shape. They do not make direct contact with the CPU. Instead, the base itself absorbs the heat to then pass it on to the heatpipes and to the fins from there. The four copper heatpipes are evenly spaced throughout the heatsink. You will also notice the two cut outs on both sides of these aluminum fins and the slightly angled nature which reaches its deepest point in the middle of each fin.


The cooler's base is far from a mirrored finish and has visible machining marks. While the base is of decent quality, it's not quite on par with the likes of the Dark Rock 3, which is fine considering the Dark Rock 3 costs twice as much as the Pure Rock.


be quiet!'s fan measures in at 120 mm x 120 mm x 25 mm and belongs to the SilentWings family. The fan's model number is BQ PUW2-12025-MS-PWM, and it makes use of a unique airflow-optimized fan-blade design that reduces noise and turbulence. As the model number suggests, it supports PWM. No LEDs and no fancy colored rings, this is just a 120 mm fan of solid quality.
