be quiet! Dark Rock Pro 5 | Dual-Fan Air Cooling

The be quiet! Dark Rock Pro 5 Processor Air cooler 120/135 mm Black 1 pc(s) delivers immense cooling performance with virtually inaudible operation. This air cooler is designed for users with demanding workstations or heavily overclocked systems who require high thermal dissipation without excessive noise. It combines a dual-fan layout with a solid black aesthetic, fitting seamlessly into high-performance UK builds.

Key Technical Metrics

Near-Silent Operation at Low Loads

This cooler utilises two fans with Fluid Dynamic Bearing (FDB) technology for longevity and reduced friction. At low speeds, the noise level measures just 8.9 dB, which is effectively silent in most environments. Because the fan speed min is 1300 RPM, it provides consistent airflow even when your system is idle. This makes it an excellent choice for quiet office work or media consumption.

High-Performance Heat Dissipation

The Dark Rock Pro 5 features a solid copper base plate and seven 6 mm heat pipes. These pipes efficiently transfer heat away from the processor to the aluminium fins. With a Thermal Design Power (TDP) rating of 270 W, this cooler handles intense processing loads. In practice, it supports demanding workstations and overclocked CPUs without thermal throttling.

Broad Socket Compatibility

This air cooler supports a wide range of processor sockets. It fits Intel LGA 1150, 1151, 1155, 1200, and 1700. It also supports AMD Socket AM4 and AM5. Because the mounting hardware accommodates both modern and older generations, it offers flexibility for upgrades. However, you should verify physical clearance inside your PC case before purchase.

Dual-Fan Layout and Dimensions

The unit includes two fans: a 135 mm front fan and a 120 mm middle fan. The fan dimensions are 135 x 135 x 25 mm and 120 x 120 x 25 mm respectively. The total cooler height is 168 mm. This compact depth of 145 mm helps maintain compatibility with most mid-tower cases. The black coating provides a uniform look that matches modern builds.

PWM Control and Fan Speeds

The fans support 4-pin PWM connectors, allowing your motherboard to regulate speed automatically. The primary fan runs between 1300 and 1500 RPM, while the second fan runs between 1700 and 2000 RPM. This dynamic control ensures cooling capacity scales with your system’s thermal demands. At high speeds, noise reaches 23.3 dB, remaining quiet under load.

Sustainable and Certified Design

This cooler holds sustainability compliance with Triman and UL ECOLOGO certificates. It also carries CE, RoHS, cTUVus, UKCA, and WEEE compliance certificates. For UK buyers, the UKCA marking confirms it meets UK regulatory standards. The mean time to failure (MTTF) for the fans is rated at 300,000 hours, indicating long-term reliability.
