Immense Cooling Power
For AMD TR4 motherboards

No compromise in silence and performance for overclocked systems and demanding graphics applications! Dark Rock Pro TR4 is designed for AMD TR4 only and provides an impressive rating of 250W TDP.
Virtually Inaudible Operation
Even at 100% PWM fan speed noise is an insignificant 24.3dB(A)
The two Silent Wings PWM fans feature advanced fluid-dynamic bearings, smooth six-pole motors and airflow-optimized fan blades. The front Silent Wings 3 fan provides extremely high air pressure, thanks to a funnel-shaped air inlet in the frame. Decoupled fan mounting with vibration-isolating elements on the heat sink.


Highly Advanced Design
The core features that result in high-end cooling
Dark Rock Pro TR4 is equipped with seven advanced technology 6mm copper heat pipes that maximize the heat conductance. Airflow-optimized, wave-contoured cooling fins with small dots on their surfaces increase the air circulation. The special black coating with ceramic particles makes a perfect transfer of heat possible.


Double-Tower Layout
Powerful cooling for your components
Dark Rock Pro TR4 contains two aluminum heat sinks. The cutouts provided enhance its RAM compatibility. Two fans are pre-installed. It is also possible to add another 120mm fan for even better cooling.


User-Friendly Elegance
Stylish and easy to install
The mounting kit for the Dark Rock Pro TR4 cooler is completely black, perfectly matching the black design of the cooler itself. You can conveniently install the cooler on the motherboard from above. The brushed aluminum top cover with its diamond cut finish adds a touch of elegance to this high-end cooler.
