LGA115x
Caution: The supplied backplate will install over the mother-
board’s stock backplate, so the motherboard’s stock backplate
must not be taken off.
Attaching the backplate2
Place the 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.
First put the plastic spacers onto the bolts of the backplate, then
add the mounting bars.
Installing the mounting bars3
Caution: Choose the alignment of the mounting bars according to
the desired final orientation of the cooler:
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 (max. torque 0.6 Nm).
If there are residual traces of thermal paste or thermal pads on
your CPU, please clean them off first. Then press a small drop
(3-4mm diameter) of NT-H1 onto the centre of the heatspreader.
Applying the thermal paste
Caution: Applying too much thermal paste will lower heat
conductivity and cooling performance!
