Fan Noise ML350 gen11
Hello,
We have a problem with loud fans on 2 new ML350 Gen11 servers.
The servers are up to date.
The fans are constantly running at over 21%.
We installed an ML350 gen11 last year and the fans are running at 11%. This is not up to date.
So it must be a driver, firmware or BIOS update.
No ML350 gen10 servers have this problem, the fans are running at 6-8%.
Maybe others have this problem and a solution.
Thanks

Re: Fan Noise ML350 gen11
Hello,
I have installed the generic Gen11 Agentless Management Service for Microsoft Windows x64, unfortunately the speed of the fans does not change. It is still at 23% and is too loud.

Re: Fan Noise ML350 gen11
Hi @peterb68
If the fan speed is high even after installing AMS, this indicates a possible hardware issue. Further troubleshooting needs to be performed to isolate the issue further. You may consider performing a server power drain to begin with. To do so, shut down the server, disconnect all the external cables including Power, Network, and External devices, then press and hold down the power button.

Re: Fan Noise ML350 gen11
I have now done what you described. After 20 minutes the fan speed increases again to 25%. So this is not a solution.

Re: Fan Noise ML350 gen11
Hi @peterb68 ,
Please try following steps -
1) Verify that the thermal configuration and should be optimized as per the CPU utilization.
2) If third party hardware such as HBAs, controllers etc are installed, test by removing one by one.
3) Remove all the RAM DIMMs and start with minimal required number of DIMMs.
4) Swap the disks and run the server with minimal disks.
5) Check the lab AC must be in proper degree, server should be seated with good air flow.
Refer this blog.

Re: Fan Noise ML350 gen11
Good morning, I also have the same problem on the ML350 gen11, minimum temperatures and constant fans at 50%. No proposed solution helped, in fact after updating the drivers and firmware in April the problem got worse. I have another ML350 gen11 purchased 6 months ago and no problems but it has older out of date drivers and firmware. So the problem concerns an update that occurred in the last 6 months. I opened a support ticket to HPE but to date no response.

Re: Fan Noise ML350 gen11
Good morning, in my case it was solved by performing a fw downgrade of the HPDA version to HPD9 of the 2 300 GB SAS disks
