WARNING: Before working inside your computer, read the safety information that
shipped with your computer. For additional safety best practices information, see
the Regulatory Compliance Homepage at www.dell.com/regulatory_compliance.
WARNING: The heat sink may be very hot during normal operation. Be sure that it
has had sufficient time to cool before you touch it.
CAUTION: Do not perform the following steps unless you are familiar with hardware removal and replacement. Performing these steps incorrectly could damage your system board. For technical service information, see the Setup Guide.
Removing the Heat Sink
CAUTION: To ensure maximum cooling for the processor, do not touch the heat transfer areas on the processor heat sink. The oils in your skin can reduce the heat transfer capability of the thermal grease.
NOTE: The original thermal grease can be reused if the original processor and processor heat sink are reinstalled together. If either the processor or the processor heat sink is replaced, use the thermal grease provided in the kit to ensure that thermal conductivity is achieved.
Clean the thermal grease from the bottom of the heat sink and reapply it.
Align the screws on the processor heat sink with the screw holes on the
chassis.
CAUTION: To prevent damage to the processor follow the marked sequence, this ensures equal pressure on the processor at all times.
Use the marked sequence on the processor heat sink to tighten the four
captive screws at the lower end of the processor heat sink.
Replace the screw that secures the heat sink to the chassis.
