Installing the CPU heatsink and fan

The Intel

Pentium

D / Pentium

4 / Celeron

/ Core™2 Duo LGA775 processor

requires a specially designed heatsink and fan assembly to ensure optimum
thermal condition and performance.

•

Install the motherboard to the chassis before you install the CPU fan and

heatsink assembly

•

When you buy a boxed Intel

Pentium

D / Pentium

4 / Celeron

/ Core™

2 Duo processor, the package

D / Pentium

4 / Celeron

/ Core™2 Duo LGA775

heatsink and fan assembly comes in a push-pin design and requires no
tool to install.

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.

To install the CPU heatsink and fan:
