BE QUIET Dark Rock 4 135 mm Silent Wings Fan CPU Cooler – Black

Back in 2009 Alpenfhn released one of the most famous coolers in PC industry the Brocken. After 2 years of R&D including hours of thermal simulations and customer feedbacks we proudly present the consequent advancement the Brocken 2.

The ideal performance of the Brocken 2 is ensured by using the new 140mm WingBoost2 premium fans that come with the cooler. With the new aerodynamically revised s-shaped wing geometry and the new WingBoosts we both could increase the airflow as well as improve the static pressure at lower noise.

The RockMount mounting system ensures a simple and secure installation of the cooleron the sockets 2011, 1366, 115x, AM3(+), AM3, AM2(+), AM2 and FM1.

HighEnd Heatpipes with gapless H.D.C-technology:Thanks to the gapless H.D.C technology the five high performance heatpipes have direct contact to the cpu.

Asymetrical heatsink for enhanced flexibilityDue to the asmetrical heatsink all memory slots can be populated even if high heatspreaders are used on the modules.

WingBoost 2 fanThe first generation of WingBoost fans already proved its exellent performance in various reviews. With the new aerodynamically improved wing geometry we could not only increase the airflow but as well inprove the static pressure at lower noise.

Many users ask themselveswhat are WingBoosts? WingBoosts are ridges on the impeller that guide the air on the air-inlet side of the impeller. Using the WingBoost 2 technology air turbulences are reduced wich leads to a lower noise level at full speed.

With the improved S-Shape geometry we could reach a higher static pressure compared to conventional designs.

RockMount – Mounting systemThe RockMount system assures a easy and save mounting on Socket2011, 1366, 115x, AM3(+), AM3, AM2(+), AM2 as well as FM1.
