2.22 - Heatsink Retention Frame Installation
After you are done installing the processor(s), you should proceed to installing the
retention frame and heatsink. The CPU heatsink will ensure that the processors do not
overheat and continue to operate at maximum performance for as long as you own them.
Overheated processors are also dangerous to the health of the motherboard.
The backplate assembly prevents excessive motherboard flexing in the area near the
processor and provides a base for the installation of the heatsink retention bracket and
heatsink.
Because there are many different types of heatsinks available from many different
manufacturers, a lot of them have their own method of installation. For the safest method
of installation and information on choosing the appropriate heatsink, use heatsinks
validated by AMD. Please refer to AMD's website at www.amd.com.
