2.5 - 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
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 .
