2.3.2 Installing the CPU heatsink and fan
The Intel
®
LGA1155 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
®
-certied multi-directional heatsink and fan.
• Your Intel
®
LGA1155 heatsink and fan assembly comes in a push-pin
design and requires no tool to install.
• Use an LGA1155-compatible CPU heatsink and fan assembly only. The
LGA1155 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.
2. 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.
