be quiet! DARK ROCK 5 Processor Air cooler 12 cm Black 1 pc(s)

The be quiet! DARK ROCK 5 is a compact high-performance air cooler with a 120 mm fan that reaches up to 2100 RPM. It delivers efficient heat dissipation with an airflow of 93.5 m³/h and a maximum air pressure of 2.73 mmH2O, while Fluid Dynamic Bearing ensures quiet operation and long-term reliability. The cooler measures 136 mm (W) x 101 mm (D) x 161 mm (H) and comes in a black finish.

Advantages

The DARK ROCK 5 combines strong cooling capacity (TDP up to 210 W) with a compact form factor that preserves compatibility with many PC builds. Its 120 mm fan offers a balance of airflow and low noise thanks to Fluid Dynamic Bearing and optimized blade design. The black finish and modest dimensions allow for installation in a variety of systems without obstructing memory slots or other components.

Suitable for

• Gaming desktops requiring reliable air cooling
• Workstations with medium to high CPU load (up to 210 W TDP)
• Compact PC builds where cooler height and clearance matter
• Systems prioritizing low acoustic noise

How to use

Mount the DARK ROCK 5 on a compatible CPU socket following the manufacturer's installation instructions and using the supplied mounting hardware. Apply an appropriate amount of thermal paste to the CPU heatspreader before installing the cooler. Ensure the fan connector is attached to the CPU fan header on the motherboard and verify clearance for surrounding components. Adjust fan control in BIOS or via software if needed to manage noise and cooling performance.

Recommendations

For best results, use a high-quality thermal paste and periodically check that the fan and heatsink are free of dust. Configure fan curves to balance noise and temperature according to workload; for sustained heavy loads, allow higher fan speeds within the specified 2100 RPM limit.
