With
the
heat-exchanger
assembly
at
an
angle
as
shown
in
the
illustration,
carefully
align
the
heat-exchanger
assembly
with
the
microprocessor
and
the
heat
exchanger
bracket
on
the
system
board.
Make
sure
that
the
alignment
pins
(the
two
heat-exchanger
nibs
that
are
closer
to
the
microprocessor)
protrude
through
the
alignment
hole
(the
opening
in
the
side
of
the
heat
exchanger
socket)
and
that
the
flange
of
the
heat
sink
rests
under
the
lip
of
the
heat-sink
socket.
6.
Gently
press
the
assembly
into
place.
7.
Close
the
heat-exchanger-assembly
release
latch,
catching
it
under

Thermal
grease
The
thermal
grease
must
be
replaced
whenever
the
heat
exchanger
has
been
removed
from
the
top
of
the
microprocessor
and
is
going
to
be
reused
or
when
debris
is
found
in
the
grease.
To
replace
damaged
or
contaminated
thermal
grease
on
the
microprocessor
and
heat
exchanger,
complete
the
following
steps:
1.
Place
the
heat-exchanger
assembly
on
a
clean
work
surface.
2.
Remove
the
cleaning
pad
from
its
package
and
unfold
it
completely.
3.
Use
the
cleaning
pad
to
wipe
the
thermal
grease
from
the
bottom
of
the
heat
exchanger.
Note:
Make
sure
that
all
of
the
thermal
grease
is
removed.
4.
Use
a
clean
area
of
the
cleaning
pad
to
wipe
the
thermal
grease
from
the
microprocessor;
then,
dispose
of
the
cleaning
pad
after
all
of
the
thermal
grease
is
removed.
