Award-winning NH-D14 cooler
Tens of thousands of enthusiast users all over the world swear by the NH-D14’s quality and performance. Recommended by more than 250 international hardware websites and magazines, it is renowned to be one of the best high end coolers on the market.

6 heatpipe dual radiator design
Providing more surface area, better heat-distribution and superior airflow efficiency than conventional tower style heatsinks, the NH-D14’s six heatpipe dual radiator design was developed to provide ultimate quiet cooling performance in dual fan mode.

Dual NF-P14/NF-P12 PWM fan setup
The NH-D14 sports a premium quality dual PWM fan setup consisting of Noctua’s award-winning NF-P12 (120mm) and NF-P14 (140mm) fans, both of which feature Vortex-Control Notches, SCD technology and SSO-Bearings in order to achieve a perfect balance of performance and quietness.

Custom designed PWM IC with SCD
Supporting fully automatic PWM speed control, the NH-D14 SE2011’s NF-P12 and NF-P14 fans use Noctua’s novel, custom designed NE-FD1 PWM IC that integrates Smooth Commutation Drive (SCD) technology. By providing smoother torque impulses, SCD suppresses PWM switching noises and thus make the fans quieter at lower speeds.
