be quiet! Dark Rock Pro 4 Review @ Vortez
 

The Dark Rock Pro 4 offers the user up to 250W of heat dissipation via a twin-tower design; that’s more than enough to deal with any current consumer CPU, even with a sizeable overclock. That heat is extracted via 7 copper heat pipes, transferring it to the ceramic coated, black fins on either tower. There’s also a pair of be quiet!’s Silent Wings fans to ensure airflow is aplenty - a 120mm on the front and a 135mm inside.
