Excessive fan noise (high speeds)

Symptom

Fans are operating at high speeds with excessive noise.

Cause
Fans can generate noise:

  • When running at a high speed (as expected)

  • When at low speed if there is an issue with the fan

Action
  1. Verify the fan status by accessing the Fans view of the HPE OneView Enclosures screen.

    For more information, see the HPE OneView Help for HPE Synergy on the Hewlett Packard Enterprise website (http://www.hpe.com/info/synergy-docs).

    Fan speeds greater than 60% are expected to be loud.
  2. If the fan is running at a speed higher than expected, see "Fans running at a higher than expected speed."
