2.3.2 Installing the CPU heatsink
The Intel
®
LGA1150 processor requires a specially designed CPU heatsink to ensure
optimum thermal condition and performance.
• When you buy a boxed Intel
®
processor, a specially designed CPU heatsink or a
CPU heatsink with a CPU fan assembly is included depending on the package. If you
buy a CPU separately, ensure that you use only Intel
®
certified multi-directional CPU
heatsink or CPU heatsink with CPU fan.
• Use an LGA1150-compatible CPU heatsink and CPU fan assembly only. The LGA1150
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.
