1. High ambient temperature
2. Incomplete seating of the CPU cooler
3. Lack of thermal compound / uneven distribution
4. Lack of case-side airflow
Check to make sure that the CPU fan is physically spinning. Confirm that the BIOS is set to cool the fan according to your configuration. Some mainboards default to a low, manual speed setting.
