Noctua’s dual-tower NH-D14 is stepping down from the throne to make way for a new updated design. The NH-D15 delivers dual-tower heatsink cooling and silence just as its predecessor has in a more efficient design, utilizing new fans and being mindful of taller memory modules.
Like the award-winning NH-U14S, the new NH-D15 uses Noctua’s NF-A15 1500 RPM fans for superior silence and airflow over the NH-D14’s NF-P14 fan. PWM controls allows for smooth fan control while a low-noise adapter is also included as an alternative which lowers the maximum fan speed to 1200 RPM.
The NH-D14’s fin stack has been re-arranged to provide better heatpipe spacing in the NH-D15, moving from 140mm to 150mm for a more uniform heat distribution. For better RAM compatibility in single fan mode, the NH-D15’s lower fins provide 64mm of clearance, even on Quad-channel RAM mainboards.
As with all latest Noctua heatsinks, the NH-D15 uses the updated SecuFirm2 multi-socket mounting system, simplified for easier installation and also comes with an NT-H1 thermal compound. The NH-D15 is backed by a 6-year warranty and has a suggested retail price of EUR 89.90 / USD 99.90.
