WARNING: The heat sink may become hot during normal operation. Allow sufficient time for the heat sink to
cool before you touch it.
CAUTION: For maximum cooling of the processor, do not touch the heat transfer areas on the heat sink. The
oils in your skin can reduce the heat transfer capability of the thermal grease.
2. Remove the side cover.
