APU & Cooler Installation
When you are installing the APU, make sure the APU has a cooler attached on the top
to prevent overheating. Meanwhile, do not forget to apply some thermal paste on APU
before installing the heat sink/cooler fan for better heat dispersion.
Follow the steps below to install the APU & cooler correctly. Wrong installation will
cause the damage of your APU & motherboard.
1. Pull the lever sideways away from the socket. Make sure to raise the lever up to a
90-degree angle.
2. Look for the gold arrow of the APU. The gold arrow should point as shown in the
picture. The APU can only fit in the correct orientation.
3. If the APU is correctly installed, the pins should be completely embedded into
the socket and can not be seen. Please note that any violation of the correct
installation procedures may cause permanent damages to your motherboard.
4. Press the APU down firmly into the socket and close the lever. As the APU is
likely to move while the lever is being closed, always close the lever with your
fingers pressing tightly on top of the APU to make sure the APU is properly and
completely embedded into the socket.
