Dear customer,
Thank you very much for choosing the Noctua NH-D15S.
Built on the basis of the legendary NH-D14 and carrying
on its quest for ultimate quiet cooling performance, our
flagship model NH-D15 is an elite- class dual tower cooler
for the highest demands.
I'm confident that you will be able to sense some of the
research, attention and care we've put into making this
cooler.
Enjoy your NH-D15S!
INSTALLATION MANUAL
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
centre on our website (ncc.noctua.at) and verify that the
cooler is fully compatible with your motherboard.
Please also make sure that your PC case offers sufficient
clearance for the cooler and that there are no compatibility
issues with any other components (e.g. tall RAM modules).
Double check that the heatsink and fan clips do not make
contact with the VGA card, other PCIe cards, motherboard
heatsinks or any other components.
Noctua cannot be held responsible for any damage or losses
caused by compatibility issues.
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 support@noctua.at.
Multilingual versions of this manual are available on our
website: www.noctua.at/manuals
Yours sincerely,
Roland Mossig, Noctua CEO

  • Page 3: Attaching The Backplate

    Position 1: Position 2: LGA1200/115x LGA1700 Fix the bolts using the NM-ICS1 clip-on spacers. Note that 2 extra clip-on spacers are supplied in case any are lost or damaged when removing the bolts at a later point. Attaching the backplate Caution: The supplied backplate will install over the motherboard’s stock backplate, so the motherboard’s stock backplate must not be taken off.
  • Page 4 LGA1200/115x LGA1700 NM-IPS1 (black) NM-IPS3 (blue) Use hole position 1 for LGA1200/115x (LGA1150, LGA1151, LGA1155, LGA1156) and hole position 2 for LGA1700 (LGA17xx family): Position 1: Position 2: LGA1200/115x LGA1700 Caution: Make sure to use the correct hole position on both ends of the NM-IMB2 mounting bars so that they will not be misaligned.
  • Page 5 Caution: Choose the alignment of the mounting bars according to the desired final orientation of the cooler. Orientation A Orientation B Caution: Make sure that the curved sides of the mounting bars are pointing outwards. Fix the mounting bars using the four NM-ITS1s thumb screws.

Transporting your system For LGA1200/115x (LGA1150, LGA1151, LGA1155, LGA1156) apply a single 4-5mm dot in the centre: Caution: Applying too much thermal paste will lower heat conductivity and cooling performance! Fastening the heatsink to the CPU Caution: Please first take off the fan as well as the protec- tion cover at the bottom side of the heatsink.
  • Page 7: Fan Setup

    Fan setup Reattach the fan using the supplied steel clips: Connect the fan to the motherboard’s CPU fan header. Depending on your CPU and the temperature inside the case, you may interconnect the supplied NA-RC7 Low- Noise Adaptor (L.N.A.) in order to further reduce the fan’s operating noise.
