removed from the heat sink or fan sink, do not touch the thermal grease on the
bottom of the heat sink or fan sink or set down the heat sink or fan sink.
Note: Removing the heat sink or fan sink from the microprocessor destroys the
even distribution of the thermal grease and requires replacing the thermal
grease. Setting down the heat sink or fan sink onto any surface when the
thermal-grease protective cover is removed will contaminate the thermal grease.
If the thermal grease becomes contaminated with particles, it must be replaced.
For information about replacing contaminated thermal grease on the heat sink or
fan sink, contact IBM Integrated Technology Services. For the most up-to-date
phone numbers, go to http://www.ibm.com/planetwide/, or in the U.S. and
Canada, call 1-800-IBM-SERV (1-800-426-7378).
