be quiet! Dark Rock Pro CPU Cooler 3, Intel / AMD

The Dark Rock Pro 3 offers an excellent balance of performance and volume and of the highest possible reliability. The improved cooling efficiency (250W TDP) and a very quiet operation (only 26.1 dB (A) at maximum power) prove that the Dark Rock Pro 3 the perfect balance of cooling and quiet operation provides – simply uncompromising silent cooling of superlatives.

Immensely high cooling efficiency

    The improved wave-shaped contour of the cooling fins with small dots on the surface to increase air circulation and contribute to a stronger convection efficiency without increasing the overall volume
    Optimized Double-Tower layout is easier, thus enabling a higher cooling capacity
    Support an additional 120mm fan for exceptional cooling requirements (fan brackets are included)
    Seven high-performance heat pipes with copper coating and aluminum caps bring the heat to the optimum point of the cooling fins and drive the heat permeability at its maximum
    The immensely high cooling capacity of 250W TDP offers a low temperature even at maximum operating
    New arrangement of heatpipes has an enhancing effect on the cooling ability

Virtually inaudible operation

    Two Silent Wings PWM fan (external: 120mm, inner: 135mm) offer a sophisticated fluid dynamic bearing with copper core and a dynamic gewuchtetes drive for optimal cooling with absolute smoothness
    Inner 135mm Silent Wings PWM fan, equipped with nine air-flow-optimized fan blades and an innovative six-pole motor for low vibration and smooth operation
    Decoupled fan assembly with vibration isolating elements on the heat sink
    Maximum 26.1 dB (A) even at 100% PWM function
