1.6.2 Installing the CPU Heatsink and Fan

The Intel® Core™ 2 Quad/ Intel® Core™ 2 Duo LGA775 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance.

zInstall the motherboard to the chassis before you install the CPU fan and heatsink assembly.

zWhen you buy a boxed Intel® Core™ 2 Quad/ Intel® Core™ 2 Duo 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.

zYour Intel® Core™ 2 Quad/ Intel® 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 you have properly applied Thermal Interface Material to the CPU heatsink or CPU before you install the heatsink and fan 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.

Orient the heatsink and fan assembly such that the CPU fan cable is closest to the CPU fan connector.

Make sure each fastener is oriented as shown, with the narrow groove directed outward.
