1.6.2 Installing the CPU heatsink and fan
Intel ® LGA775 processors require 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, making sure that
the four fasteners match the
holes on the motherboard.

• 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 Intel ® -certified multi-directional
heatsink and fan.
• Your Intel ® LGA775 processor 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 you have properly applied Thermal Interface Material to
the CPU heatsink or CPU before you install the heatsink and fan
assembly.
Make sure that you have installed the motherboard to the chassis before
you install the CPU fan and heatsink assembly.
Make sure 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.
