be quiet! Dark Rock 5 Review

The be quiet! Dark Rock 5 sits a step below the Dark Rock Pro 6 in be quiet!'s dual-tower air lineup, dropping to 6 heatpipes and losing the semi-passive quiet mode while keeping the same quiet-first Silent Wings fan pairing. It handles up to 250W of TDP, aimed at buyers who want most of the Pro 6's cooling without its flagship price.

Thermal Performance

Six heatpipes and a dual-tower heatsink handle up to 250W of TDP, a genuine step below the Dark Rock Pro 6's 300W ceiling but still comfortable for most mainstream and moderately overclocked builds.

Fan Design and Noise

The same 135mm-plus-120mm Silent Wings PWM pairing used on the Pro 6 keeps noise low, though the Dark Rock 5 drops the Pro 6's hardware performance/quiet toggle switch and semi-passive full-fan-stop mode.

Comparison to Alternatives

Against the be quiet! Dark Rock Pro 6, covered elsewhere on this site, the Pro 6 adds a semi-passive silent mode and a higher 300W TDP ceiling, while this Dark Rock 5 costs meaningfully less for buyers who don't need the extra headroom. Against the DeepCool AK620, also covered elsewhere on this site, the Dark Rock 5 is quieter at comparable loads, though the AK620 is the better straight value pick.
