Instructions for installing the CPU and heatsink-fan are presented in more
detail in our article on
How to Install an AMD Socket A Athlon or Duron Processor.
If you have never done it before, that article and AMD's
AMD Processor and Heatsink Installation Guide should be
reviewed before proceeding. Many AMD Socket A Athlon and Duron
processors are damaged during installation. Reading those articles
could save your CPU.
Inspect the heat sensor to be sure it hasn't been pushed into the socket.
If needed, bend it gently upward so it is vertical. The thermisters
I've seen on three of these motherboards do not quite touch the bottom of
4. Inspect the CPU for bent pins
Unlatch and raise the socket lever all the up, orient the corner of
the CPU with the arrow towards the corner of the socket as shown to the
right (upper left in the picture), and carefully and gently insert it into
the socket. Never force a CPU into its socket.

6. Inspect the sides of the socket to be sure
the CPU is fully seated, and latch the leaver.
7. You may want to reposition the fan on top of
the heatsink for better routing of the fan wires to the connector on the
motherboard. I didn't as it was not required for this fan, which towers above
the motherboard. Many CPU fans can be reoriented by unscrewing the
four mounting screws rotating the fan assembly to the desired orientation
and screwing the fan back down. Evenly tighten and do not over-torque
the screws. Take care not to scratch the bottom of the heatsink.
Unbox the heat-sink fan and slowly and carefully remove the covering
protecting the thermo pad. This may leave some residue behind on the heatsink. I would removed it form the metal part of the heat sink with
a quality degreaser and wash and a paper towel. Rubbing alcohol should
work. Be careful not to get any of it on the thermo pad, the square
thing on the round copper part of the heatsink.
9. A good, lint-less way to clean the CPU die is
to put on a clean, disposable vinyl glove, wet the end of your index finger
with degreaser-wash (one that does not leave any kind of residue) or rubbing alcohol, and gently apply it to the surface
of the die. A kleenex or paper towel will do the job. This is
one time you absolutely want to be sure you want to take anti-static
10. Look at both heat sink and CPU at an angle
with good lighting to be sure no lint or dirt is left behind. A bench
mounted, magnifying glass with a light in the middle is a good way of doing this.
11. Verify that all four rubber standoffs are
still on the CPU! The CPU cannot be operated without them to keep the
heatsink flat on, and in full contact with the die and to maintain an air
gap between the heatsink and the CPU components outside of the die.
Note the step on the bottom of the heat-sink fan. Position the
heatsink so it can step over the raised part of the socket. Be careful
not to apply force on the spring clips unless the heat sink is squarely on
the CPU. That can break the die (the little square, shiny thing in the
middle of the processor, the actual CPU) loose from the rest of the
processor or crack it. Hook the end of the spring clip at the opposite side from
the step over the lug on the socket. If you take your time you can do
it without any noticeable force on the CPU.
This is the tricky part and does apply force on the rubber standoffs and on
the die... Suggest reading all of this step before before attempting it.
The other end of the spring is attached with a screw driver. Make sure
the screw drive is properly inserted in the spring as shown, hold the heatsink-fan firmly so that it is squarely on the CPU, properly positioned,
and does not ride up on the step on the socket. It will take some
noticeable force to get the clip on the lug. Be very careful not to
let the screw driver slip off the spring and damage the motherboard. Hold on, catch the lug, push down, out a little, and in.
14. Look along the sides and make sure the
heatsink-fan is positioned properly and not riding up on the step.
Yes, you can unlatch it and adjust it if need be.
15. Plug the fan wire into the jack marked CPU
FAN on the motherboard, neatly coil-up the excess CPU fan wire, and
zip-tie it to keep the wire out of the CPU fans, and trim the access with
diagonal cutters. Zip ties have three purposes in a PC: keep wires out
of fans, improve ventilation, and produce a neat, professional appearance.
If a new computer arrives without zip-tied wires it was not built by a
