Attaching the mounting bars
First put the plastic spacers onto the screw threads, then fix the
mounting bars using the 4 long screws.
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 support@noctua.at.
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.

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

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 2
Caution: Applying too much thermal paste will lower the heat
conductivity and cooling performance!
