Be Quiet! Dark Rock Pro C1 Dual Tower CPU Cooler Review

Trendiness is evident instantly after taking the Dark Rock Pro out of the its packaging. Black fans combined with the full-aluminium cover and dark nickel plated finish create an elegant appearance.

Both of the Silent Wings PWM fans can operate at up to 1700 RPM for a rated noise output of 20.0 dbA. A 300,000 hour MTBF ensures that you aren’t likely to be needing to change these fans any time soon.

Wave-design aluminium fins are employed to reduce prevent extra noise being created while maintaining maximum airflow levels. A specific fan-clip channel makes positioning the front 120mm fan at a user-definable height an option.

Serrated fins and an airflow-enhancing channel should ensure that the pair of 1700 RPM fans offer excess performance without becoming a liability.

A black-finish aluminium cover hides the potentially ugly summit of Be Quiet!’s heatsink creating an elegant design. 14 steel heatpipe caps are located on the cover which ensures that the sturdiness of the heatsink remains constant.

7 6mm nickel-plated copper heatpipes exit the CNC machined base. The base isn’t quite a mirror finish but is still fairly shiny. Be Quiet!’s engineers chose to have each heatpipe entering the fin array at different location ensuring an even spread of the cooler’s thermal load.

An innovative 4-pin PWM splitter is built into 1 of the 120mm fans. This splitter ensures that users such as myself can have both fan’s speeds controlled via the motherboard’s PWM header even when only 1 header is available.
