- If the loading on this individual blade server is high, that should be normal to request the high fan speed.
- You can use IPMITool to get the blade server’s sensor state. If there’s sensor in abnormal state, it may request the high fan speed as well. Contact Dell Support (bottom of page) if you need further assistance on the blade server.
