Asus M4A77D - Manual (Page 20)

1.6.2 Installing the heatsink and fan
Ensure that you use only AMD-certified heatsink and fan assembly.
To install the CPU heatsink and fan:
1.
Place the heatsink on top of the installed CPU, ensuring that the heatsink fits properly
on the retention module base.
• The retention module base is already installed on the motherboard upon purchase.
• You do not have to remove the retention module base when installing the CPU or
installing other motherboard components.
• If you purchased a separate CPU heatsink and fan assembly, ensure that a Thermal
Interface Material is properly applied to the CPU heatsink or CPU before you install the
heatsink and fan assembly.

the CPU, heatsink, and the retention mechanism. If the instructions in this section do not
match the CPU documentation, follow the latter.
2. Attach one end of the retention bracket to the retention module base.
