Cause
• The system temperature sensor is reading over threshold.
• An air baffle is missing or not installed properly and causing a disruption of the airflow.
• The processor heatsink is not installed as indicated in the server documentation.
• A required fan is not installed in the server.
Action
1. Update the server to the latest firmware versions, such as BMC firmware, system BIOS, option
firmware, etc.
2. Verify the Temperature sensor. Fan speeds can be high if a sensor temperature is over threshold.
3. Verify that all air baffles and required blanks, such as drive blanks, processor heatsink blanks, power
supply blanks, etc., are installed.
4. Verify that the correct processor heatsink is installed.
5. Verify that the correct fan is installed.
Excessive fan noise (high speeds)
Symptom
Fans are operating at high speeds with excessive noise.
Cause
Fans can generate noise if running at a high speed (as expected) or when at low speed if there is an
issue with the fan.
Action
1. In the BMC WebUI, navigate to the Sensor page.
2. Click the Fans sensor.
3. Verify the fan status and fan speed. Fan speeds greater than 60% are expected to be loud.
4. If the fan is running at a speed higher than expected, see Fans running at a higher than expected
speed .
Excessive fan noise (low speeds)
Symptom
Abnormal/rattling noise observed at low fan speeds might indicate an issue with the fan.
