Noctua NH-D9L

Noctua NH-D9L

The NH-D9L is a premium grade dual tower CPU cooler that has been designed to provide excellent quiet cooling performance at a
height of only 110mm. Its comparably low
profile (15mm lower than classic 9cm tower coolers such as the NH-U9S) doesn’t only guarantee full 3U compliance but also makes the NH-D9L ideal for compact HTPC and
Small Form Factor cases that have airflow paths parallel to the mainboard. Thanks to its 95x95mm footprint, the NH-D9L clears the RAM and PCIe slots on all Intel based
and most AMD based ITX mainboards. The included NF-A9 premium fan supports automatic speed control via PWM for outstanding quie
tness of operation and a second,
optional NF-A9 fan can be added for further improved performance in dual fan mode. Topped off with the trusted, pro-grade SecuFirm2 multi-socket mounting system,
Noctua’s proven NT-H1 thermal compound and full 6 years manufacturer’s warranty, the NH-D9L forms a highly compact premium package for space-restricted applications.

Low-profile tower design for better airflow efficiency
While most low-profile coolers blow air towards the motherboard, the NH-D9L is a tower style
cooler that bows parallel to the mainboard, which allows for superior airflow efficiency in cases
with front intake and rear exhaust fans that create an airflow path parallel to the mainboard.

3U compatibility
Whereas classic 9cm coolers with up to 125mm height fit 4U rack mount cases, the NH-D9L’s
reduced height of 110mm allows it to also fit 3U chassis. This makes it ideal for noise-sensitive
3U applications in fields such as audio or video processing.

100% compatibility with PCIe cards on mini-ITX
Many Intel LGA115x based mini-ITX mainboards have the PCIe slot sitting right next to the
95x95mm socket zone. While larger coolers that exceed this zone are likely to block the PCIe
slot, the 95x95xmm sized NH-D9L provides full compatibility with PCIe cards, be it on ATX,
microATX or ITX.

NF-A9 premium fan
The highly optimised NF-A9 premium fan features Noctua’s proprietary AAO frame as well as
sophisticated aerodynamic design measures such as Flow Acceleration Channels, which allows it
to further improve the renowned efficiency of Noctua’s previous 92mm models and contributes
to the NH-D9L’s superior cooling performance.

Dual fan ready
The NH-D9L includes an extra set of fan mounting clips for users who want to achieve even better
cooling performance by adding a second, optional NF-A9 to the front fin stack. Using the y-cable
supplied with the NF-A9 PWM retail fan, both fans can be connected to one CPU fan header.

SecuFirm2 mounting system
Noctua’s SecuFirm2 mounting systems have become synonymous with quality, safety
and ease of use. Supporting Intel LGA115x (LGA1150, LGA1151, LGA1155, LGA1156),
LGA2011 and AMD (AM3(+), AM2(+), FM1, FM2(+)), the SecuFirm2 mounting
included with the NH-D9L guarantees perfect contact pressure and maximum convenience
on all current sockets.

PWM support and Low-Noise Adaptor
The NF-A9 92mm fan supplied with the NH-D9L supports PWM for convenient automatic
speed control through the mainboard. In addition, the maximum fan speed can be reduced
from 2000 to 1550rpm using the supplied Low-Noise Adaptor for even quieter operation.
