Removing the mainboard
Step 1:
In case you want to use the cooler on an assembled system,
you first have to remove the mainboard from the case in order
to be able to install the supplied backplate.
Caution: On LGA1366 and LGA1156/1155, the supplied back-
plate will install over the mainboard’s stock backplate, so the
mainboard’s stock backplate must not be taken off.
Required mounting parts:
First put the four bolts into the holes appropriate for your
mainboard’s CPU socket.
