The Dark Rock 4 is a high-performance air cooler engineered to maintain thermal stability in computing environments handling demanding workloads. The unit utilizes a robust single-tower heatsink design, where heat is efficiently transferred from the copper base plate through six nickel-plated heat pipes to a dense aluminum fin array. Heat dissipation is managed by a single 135 mm Silent Wings fan, which employs a Fluid Dynamic Bearing (FDB) for prolonged operational stability.

Fan speed is regulated via PWM support, allowing rotational adjustment up to 1400 RPM based on current processor load requirements. The cooler is certified for a Thermal Design Power (TDP) rating of 200 W, supporting substantial CPU overclocking capabilities. Installation hardware is provided to ensure broad compatibility with a range of modern and legacy Intel and AMD platforms, including LGA 1700 and AM5 sockets. The total height measures 159.4 mm, requiring verification against specific chassis clearances.
