2.3.2 Installing the CPU heatsink and fan
The Intel ® Core TM 2 Duo / Core TM 2 Extreme / Pentium ® D / Pentium ® 4 / Celeron
®
LGA775 processor requires a specially designed heatsink and fan assembly to
ensure optimum thermal condition and performance.
To install the CPU heatsink and fan:
1. Place the heatsink on top of the
installed CPU, ensuring that the
four fasteners match the holes on
the motherboard.

of the groove
• When you buy a boxed Intel ® Core TM 2 Duo / Core TM 2 Extreme / Pentium ®
D / Pentium ® 4 / Celeron ® processor, the package
includes the CPU fan and heatsink assembly. If you buy a CPU separately,
ensure that you use only Intel ® -certified multi-directional heatsink and fan.
• Your Intel ® Core TM 2 Duo / Core TM 2 Extreme / Pentium ® D / Pentium ® 4 /
Celeron ® 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, ensure that
you have properly applied Thermal Interface Material to the CPU heatsink
or CPU before you install the heatsink and fan assembly.
Ensure that you have installed the motherboard to the chassis before you install
the CPU fan and heatsink assembly.
Ensure to orient each fastener with the narrow end of the groove pointing
outward. (The photo shows the groove shaded for emphasis.)
Orient the heatsink and fan
assembly such that the CPU
fan cable is closest to the CPU
fan connector.
