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 iLO web interface, navigate to the Information > System Information page.
2. Click the Fans tab.
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."
