1.3.2 Installing the heatsink and fan The AMD Athlon™ 64FX or AMD Athlon™ 64 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance. Make sure that you use only qualified heatsink and fan assembly. To install the CPU heatsink and fan: 1. Place the heatsink on top of the installed CPU, making sure 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, make sure that a Thermal Interface Material is properly applied to the CPU heatsink or CPU before you install the heatsink and fan assembly.
