Chapter 6 Installing an Additional Processor

Refer to the heatsink installation procedure earlier in this chapter.
CAUTION To prevent damage to the replacement processor, remove the
old patch and install a new thermal patch to the bottom of the
heatsink before installing it on the new processor.
The heatsinks are not reusable unless the thermal patch has
been replaced each time the heatsink is removed. Each time
the heatsink is used on the processor, some of the thermal
material is removed from the thermal patch, which could
cause poor heat transfer and overheating.
