The HSF type will depend on the default processor model. The
figures below show the HSF types available for the Altos G330
system.

connector.
(2) Loosen the four HSF mounting pins.
(3) Twist the HSF sightly to break the thermal grease bond loose.
Once the thermal grease bond is broken, lift the HSF away

patch facing upward. Do not let the thermal patch touch the
work surface.
5 Use an alcohol pad to wipe off the thermal grease from both the
HSF assembly and the processor socket retention plate.
