intothesocket.
Forexample:ThenewestPentiumIIIprocessor(FC-PGA2package).
Please make sure the CPU type is supported by the motherboard.
If you do not match the CPU socket Pin 1 and CPU cut edge well, it will cause
improper installation. Please change the insert orientation.

Please use Intel approved cooling fan.
We recommend you to apply the thermal paste to provide better heat
conduction between your CPU and heatsink.
Make sure the CPU fan power cable is plugged in to the CPU fan connector,
this completes the installation.
Please refer to CPU heat sink user’s manual for more detail installation
