Installing the CPU heatsink and fan
The Intel® LGA775 processor requires a specially designed heatsink and fan assembly to ensure optimum
thermal condition and performance.
• 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 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.
Note:
Make sure that you have installed the mainboard to the chassis before you install the CPU fan
and heatsink assembly.
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.
Note:
Orient the heatsink and fan assembly such that the CPU fan cable is closest to the CPU fan
connector.
Make sure to orient each fastener with the narrow end of the groove pointing outward.
(The photo shows the groove shaded for emphasis.)
