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, click Power & Thermal in the navigation tree.
  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 higher speed than expected, see "Fans running at a higher than expected speed."
