Installing the CPU heatsink and fan

The Intel

LGA1156 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, ensure that you use only

Intel

-certified multi-directional heatsink and fan.

• Your Intel

LGA1156 heatsink and fan assembly comes in a push-pin design and

requires no tool to install.

• Use an LGA1156-compatible CPU heatsink and fan assembly only. The LGA1156 socket

is incompatible with the LGA775 and LGA1366 sockets in size and dimension.

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

connector.

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.

Push down two fasteners at a time in

a diagonal sequence to secure the

heatsink and fan assembly in place.

If you purchased a separate CPU heatsink and fan assembly, ensure that the Thermal

Interface Material is properly applied 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.
