22h IOH Therm Margin 1. Check for clear and unobstructed airflow into and out of chassis.
2. Ensure SDR is programmed and correct chassis has been selected.
3. Ensure there are no fan failures.
4. Ensure the air used to cool the system is within the thermal specifications for the system (typically below 35°C).
