Mounting heat sink
i Use only the heat sink supplied with your system!
Be sure to use heat conducting material between the processor and the heat sink. If a heat
conducting pad (rubber-like foil) is already applied to the heat sink, then use it. Otherwise you must
apply a very thin layer of heat conducting paste.
Heat conducting pads can only be used once. If you remove the heat sink, you must clean it and
apply new heat conducting paste before you remount it.

► Depending on the configuration variant, you
must pull a protective foil off the heat sink or
coat the heat sink with heat conducting
paste before fitting it.

model - with four screws or push it into the
mounts.
