Hardware Installation
Do not apply the paste if the fan / heatsink already has a
patch of thermal paste on its underside. Peel the strip that
covers the paste then place the fan / heat sink on top of the
CPU.
2. After placing the fan / heat sink on top of the CPU, latch the
retaining clip on one side of the fan heat sink onto the pro-
truding tab on the side of the socket.
3. Push down the other retaining clip until it latches and lock
onto the protruding tab on that side of the socket. Make sure
there is sufficient air circulation across the CPU fan and heat
sink.
4. Connect the CPU fan's cable connector to the CPU fan con-
nector on the system board.
