Installing The Heatsink - HP LP 1000r Service Manual

Chapter 6
NOTE

Installing the Heatsink

Once the processor is installed, the heatsink must be installed on top of the processor. A thermal patch on
the bottom of the heatsink provides thermal bonding between the heatsink and the processor. The thermal
patch must be replaced if the heatsink is removed (even temporarily) from the processor. You will find extra
thermal patches taped to the PCI card cage inside the server.
1. Remove the heatsink from the shipping container. Do not touch the thermal patch on the bottom
of the heatsink.
2. Inspect the thermal patch. Replace the patch if it is damaged:
a. Make sure you are grounded with a static-dissipating wrist strap.
b. Remove the damaged patch. If you are reinstalling a heatsink on a processor, also scrape
off any thermal material remaining on top of the processor chip. You may use your fingernail
to scrape the material off.
c. To install a new thermal patch, peel off the backing, and place the patch in the area marked
at the center of the heatsink.
CAUTION

Installing the Processor on the System Board
No speed switch settings are required for the supported processors (867 MHz, 933
MHz, or 1 GHz) in the HP Netserver. These processors rely on the internal settings
within the processors and do not rely on external switch settings on the system
board.
Heatsinks are not reusable unless the thermal patch is replaced each time the
heat sink is removed, even if it is temporarily removed and reinstalled on the
same processor.
