Note: Make sure that the heat sink is level with the motherboard.

-The heat sink is not completely secured with the screws.
• Do not move the secured heat sink.

Removing a Processor
To remove the CPU, prepare for removal referring to steps 1 and 3 of the installation
procedure and do the reverse procedure of steps 11 to 4. To remove the heat sink, first
remove the screw, slightly move the heat sink, and then completely remove the heat
sink.
Caution:
•
Do not remove any CPU unless it failed.
• After the operation, heat may make the cool seat at the bottom of the
heat sink adhere to the CPU. To remove the heat sink from the CPU, first
turn the heat sink to the left and right lightly to make sure that the heat
sink is not stuck to the CPU. Removing the heat sink together with the
CPU may cause the CPU and/or socket to be damaged.
