HPE DL380 Gen10 Fan Noise

[sdfafafafa]

We have a few VMs and two drive arrays on a DL380 Gen10 server.  After a recent firmware and OS update (ESXi customized 7.0.3 from HP) the fan speeds have doubled and now run at 29-49%, which is obnoxiously loud.  Nothing about the environment or the load has changed.  Does anyone have any suggestions? We've been putting up with this for a week now.

Did you have any luck resolving this? I'm having the same issue with 2 DL380 Gen 10s and the only change I'm aware of is iLO updating to 3.04

Greetings!

As per the screenshot, I could see 3rd party drives. Please test the server with HPE drives and check the result.

The non HP drives have never been a problem until the firmware update - The server ran fine for a full calendar year.  We can test this after hours.

-> Also verify Ambient/environmental temperature where the server is located. 

-> Verify that all air baffles and required blanks, such as drive blanks, processor heatsink blanks, power supply blanks, etc., are installed. to ensure proper air flow within server.

-> Please ensure thermal configuration is set to Optimal cooling

@BPSingh We removed all non-HP drives and rolled back system BIOS to 2.7.2 and the fan noise is still very high.   Does anyone have any further suggestions?  Nothing else has changed in the environment, ambient temperatures are stable.

Please check the version of ILO, SPS and Innovation Engine running on the server. Update to the latest version and check the result. If the issue continues, please create a support case and provide the AHS logs so we can pinpoint the root cause.

We are experiencing the same after updating to iLO 3.04. We have reverted back to 3.03 at the moment.

It looks like after updating to 3.04 the temperature sensor 27 for embedded lom is missing:

sensors on 3.03:

sensors on iLO 3.03

sensors on 3.04
sensors on iLO 3.04

fan speed on 3.04:

fan speed on iLO 3.04

Downgrade the ilo firmware.

3.04 > 3.03 

Resolve after Downgrade.

Update ilo to 3.06, sensor 27-LOM is active and fan speed is normal:
