be quiet! Dark Rock Pro 4 @ TechPowerUp
 

be quiet! looks to recapture the high-end air-cooling crown with the new and improved Dark Rock Pro 4. It is a dual-fan, dual-tower design that will certainly turn a few heads. However, it won't be due to noise. Silent and powerful, this new challenger looks to dethrone Noctua's NH-D15.
