Fan
When the cooling modules operate under normal conditions, the cooling fans run at a low speed. The
cooling fans raise their rotation speed to increase the airflow under the following conditions:
•
Component failure: If the cooling module, PSU, or temperature failed.
•
Elevated temperature: If the temperature breaches the upper threshold set for any of the interior
temperature sensors.
During the initialization stage, the cooling fans operate at a high speed. The speed is lowered when the
initialization is completed and no errors are detected.
