The Dark Rock Pro 4 is a dual-tower air cooler engineered for effective high-end CPU thermal management. It carries a thermal design power (TDP) rating of 250W, making it suitable for use with high-wattage processors and moderate overclocking applications. The heatsink utilizes seven high-performance copper heat pipes to rapidly transfer thermal energy away from the nickel-plated copper base plate. This efficient thermal dissipation is facilitated by the large aluminum fin array, which is optimized for maximum surface area and heat exchange.

Cooling performance is handled by two distinct Silent Wings PWM fans operating in a sequential configuration: a 120mm unit and a 135mm unit. These fans incorporate Fluid Dynamic Bearings and maintain a rotational speed range of 1200 RPM minimum to 1500 RPM maximum. The acoustic profile is managed aggressively, ensuring a low noise output that peaks at 24.3 dB under maximum speed. The robust mounting kit accommodates current generation Intel and AMD platforms, including LGA 1700 and AM5, for versatile system integration.
