2.4.3. Installing.the.CPU.fan.and.heatsink.assembly
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, make sure 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.
8. Insert the load lever under the
retention tab.
If you purchased a separate CPU heatsink and fan assembly, make sure 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.
