1.4.2Installing the CPU Heatsink and Fan

The Intel® socket 479P Core™ Duo / Core™ Solo / Core™ 2 Duo CPU processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance.

Note! ! Install the motherboard to the chassis before you install the CPU fan and heatsink assembly.

!When you buy a boxed Intel® processor, the package includes the CPU fan and heatsink assembly. If you buy a CPU separately, make sure that you use only an Intel® - certified multi - directional heatsink and fan.

Caution! If you purchased a separate CPU heatsink and fan assembly, make sure that you have properly applied Thermal Interface Material to the CPU heatsink or CPU before you install the heatsink and fan assembly.
