Dear customer,

Thank you very much for choosing 

a Noctua cooler for your Intel 

LGA1200/LGA115x system. We always like to think of our coolers 
as safe long-term investments: Not only are they built to last, 
but we also provide upgrade kits so that you can keep using 
your trusty Noctua heatsink whenever you do a system upgrade. 

Enjoy your Noctua cooler on LGA1200/LGA115x!

 

 

Yours sincerely,

 

 

Roland Mossig, Noctua CEO

Required mounting parts:

Caution: Choose the alignment of the mounting bars according to 
the desired final orientation of the cooler: 

Orientation A

Orientation B

First put the NM-IPS1 plastic spacers onto the bolts of the  
backplate, then add the NM-IMB2 mounting bars. Use hole 
position 1 on the mounting bars. 

  Installing the mounting bars

Place the NM-IBP2 backplate on the rear side of the motherboard 
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 motherboard’s 
stock backplate.

Caution: Make sure to install the fastening brackets in the correct 
position.

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 mother-
board tray, you first have to remove the motherboard from the 
case in order to be able to install the supplied backplate.

  Removing the motherboard

Then fix the new NM-SFB2 fastening brackets to the cooler (you 
can either use the original screws or the supplied NM-SSC1 
screws). Tighten the screws until they stop, but do not use exces-
sive force (max. torque 0.5 Nm).

  Fixing the fastening-brackets to the cooler

1

Caution: The following cooler models already use the NM-SFB2 or 
compatible fastening brackets, so if you use one of these models, 
please skip this step and directly proceed to the next one:  
NH-D14 SE2011,  NH-D15 SE-AM4 and NH-L9x65 SE-AM4. If 
you use the NH-U12S SE-AM4 you can also skip this step, but in 
this case, you need to use the NM-IMB3 mounting bars supplied 
with the cooler rather than the NM-IMB2 bars supplied with this 
kit in step 2.

First take off the original fastening-brackets from the cooler by 
unscrewing the four short screws.

Caution: The supplied backplate will install over the motherboard’s 
stock backplate, so the motherboard’s stock backplate must not 
be taken off.

This manual will guide you through the installation process step 
by step using an NH-U12P heatsink as an example. Please note 
that the installation procedure is identical for all models.

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 [email protected].
