When installing: Apply 1 gram (approx.) of thermal
grease to the underside of the fan
assembly, spreading it evenly with the
provided spatula. Do not apply thermal
grease directly to the CPU. Then, when
the fan is in place, tighten the screws in
this order: A; B; and C.
Caution: When installing, be sure the screw that was
moved from position 2 to 3 above, is
returned to its original location.
