When
you
receive
a
new
microprocessor,
you
will
also
receive
a
new
heat
sink
and
vacuum
pen.
You
must
use
the
new
heat
sink
with
the
new
microprocessor.
If
you
use
the
old
heat
sink
with
the
new
microprocessor,
your
computer
might
over
heat
and
could
cause
intermittent
problems.
Important
Do
not
touch
the
gold
contacts
on
the
bottom
of
the
microprocessor.
Use
the
vacuum
pen
provided
to

and
install
the
microprocessor.
If
you
must
touch
the
microprocessor,
touch
only
the
sides.

the
microprocessor.
Important
Leave
your
computer
turned
off
for
at
least
one
hour
before
removing
the
microprocessor
to
allow
the
thermal
interface
between
the
microprocessor
and
the
heat
sink
time
to
cool
down.
