Troubleshooting System Cooling Problems
CAUTION: Many repairs may only be done by a certified service technician. You

• System cover, cooling shroud, EMI filler panel, memory-module blank, or
back filler bracket is removed.
• Ambient temperature is too high.
• External airflow is obstructed.
• The cooling fan is removed or has failed. See "Troubleshooting Cooling
Fan" on page 112.
• The expansion card installation guidelines have not been followed. See
