Noctua NH-D9L User manual

Required mounting parts:
Dear customer,
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.
Enjoy your NH-D9L!
Yours sincerely,
Roland Mossig, Noctua CEO
This manual will guide you through the installation process of the
SecuFirm2™ mounting system step by step.
Prior to installing the cooler, please consult the compatibility list
on our website (www.noctua.at/compatibility) and verify that
the cooler is fully compatible with your motherboard.
Should you encounter any difficulties, please check the FAQs on
our website (www.noctua.at/faqs) and don’t hesitate to contact
our support team at [e-mail].
Noctua cannot be held responsible for any damage or losses
caused by compatibility issues.

Removing the mainboard
In case you want to use the cooler on an assembled system and
your case doesn’t have a cut-out at the rear side of the mainboard
tray, you first have to remove the mainboard from the case in
order to be able to install the supplied backplate.
Step 1
2x NM-IMB2 Mounting Bars1x NM-IBP2 Backplate
4x NM-ITS1 Thumbscrews4x NM-IPS1 Spacers
Place the backplate on the rear side of the mainboard so that the
bolts stick through the mounting holes.
Caution: Please make sure that the three cut-outs in the
supplied backplate align with the screws of the mainboard’s stock
backplate.
Installing the mounting bars
Caution: Choose the alignment of the mounting bars according to
the desired final orientation of the cooler:
Step 3
First put the plastic spacers onto the bolts of the backplate, then
add the mounting bars.
Attaching the backplate
Caution: The supplied backplate will install over the mainboard’s
stock backplate, so the mainboard’s stock backplate must not be
taken off.
Step 2

Caution: Make sure that the curved sides of the mounting bars are
pointing outwards.
Fix the mounting bars using the 4 thumb screws.
Caution: Gently tighten the screws until they stop, but don’t use
excessive force.
Applying thermal paste
If there are residual traces of thermal paste or thermal pads on
your CPU, please clean them off first. Then press a small drop
(4-5mm diameter) of NT-H1 onto the centre of the heatspreader.
Step 4
Caution: Applying too much thermal paste will lower heat
conductivity and cooling performance!

Then put the heatsink onto the CPU and screw it to the screw
threads of the mounting bars.
Caution: Tighten the screws until they stop.

Fastening the heatsink to the CPU
Caution: Please first take off the fan and the cardboard between
the fan and the fins as well as the protection cover at the bottom
side of the heatsink.
Step 5
Fan Setup
Step 6
Reattach the centre fan using the supplied steel clips:
Connect the fan to the mainboard’s CPU fan header. Depending
on your CPU and the temperature inside the case, you may
interconnect the supplied NA-RC7 Low-Noise Adaptors (L.N.A.)
in order to further reduce the fans’ operating noise.
Caution: When using the L.N.A., check the temperature of your
CPU using appropriate software (e.g. the respective applications
of your mainboard manufacturer), in order to evade automatic
throttling of the CPU due to the increased temperature. If the
cooling performance is insufficient, please increase case
ventilation or remove the L.N.A.
Even with high-grade products and strict quality control, the
possibility of defects cannot be eliminated entirely. Therefore,
we aim at providing the highest possible level of reliability and
convenience by offering a warranty period of 6 years and direct,
fast and straightforward RMA service.
Should you encounter any problems with your NH-D9L, please
don’t hesitate to contact our support team ([email protected]).

Adding a second fan
The NH-D9L includes an extra set of fan clips and anti-vibration
strips for installing a second NF-A9 fan to the front fin stack in
push/pull mode in order to further improve cooling performance.
The y-cable supplied with the retail NF-A9 fan can be used to
control the speed of both fans via the same mainboard fan header.

Installing the mounting bars
First screw the NM-IBT2 bolts into the screw threads of the
LGA2011 socket frame.
Step 1
Then put the NM-IMB2 mounting-bars onto the bolts.
Caution: Make sure that the curved sides of the mounting bars are
pointing outwards.

Step 2
Caution: The SecuFirm2™ mounting system requires a back-
plate, which is preinstalled on most AMD mainboards. If your
mainboard doesn’t have a backplate, please contact our support
team at [e-mail].
Removing the retention module
If your mainboard uses a retention module for CPU cooler instal-
lation, please remove it first. The SecuFirm2™ mounting system
will install directly to your mainboard’s stock backplate on the rear
side of the socket.
