How to Build a Computer with
AMD Socket A Athlon or Duron Processor
Part 3 - Setup the Motherboard

Install the Processor. 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 Socket
A 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
20. Inspect the heat sensor (3) to be sure it hasn't
been pushed into the socket. If needed, bend it gently upward so it
will make contact with the bottom of the CPU.
21. Inspect the CPU for bent pins
Unlatch and raise the socket lever (2), orient the knocked-off corner
of the CPU as shown to the right, and carefully and gently insert it into
the socket. Never force a CPU into its socket.
23. Inspect the sides of the socket to be sure the CPU
is properly seated and latch the leaver.
24. 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. 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 scratch the bottom
of the heatsink.
25. If the heatsink already has a thermo pad attached,
follow the manufacture's and AMD instructions for preparing it. Usually,
it has a protective film that is easily pealed off.
You must employ a quality thermal compound, whether
it is already affixed to the heatsink or not.
26. If the heat sink does not have the thermo compound
already attached, clean the raised part of the bottom of the heat-sink fan
with a quality degreaser and wash and a lint-free cloth (or lens cleaner). Rubbing
alcohol, and, if you are careful not to shred it, a good quality Kleenex
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 or rubbing
alcohol, and gently apply it to the surface of the die. This is one time
you absolutely want to be sure you take take those anti-static precautions.
28. 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 is a good way of doing this.
If you are using thermal grease, don one disposable vinyl glove on the hand
you most favor and dab a little (very little) on the end of your index finger.
This works much better than putting the compound on
the CPU die and then trying to smear it over the surface. It's better
to have too little compound on your finger than too much. You can
always add more.
Carefully dab the compound on the surface of the CPU die and no where else. Cover
the entire surface with a thin, even, nearly semi-transparent coat of compound. No
Do not apply heatsink compound to the bottom of the
31. 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.
