Step 1
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 2
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.
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.
Step 3
Installing the mounting bars
First put the plastic spacers onto the bolts of the backplate, then
add the mounting bars.
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 4 thumb screws.
Caution: Gently tighten the screws until they stop, but don't use
excessive force.
