ProLiant DL20 Gen10 very noisy

[Pierrot Robert]

Hello,

I have a brand new ProLiant DL20 Gen10 server and it is very noisy. According to iLO, the Fan #3 is always running at around 50%. All temperatures are way below acceptable range in iLO.

What I tried do far:

• Reset the NVRAM using the S6 switch
• Install "iLO 5 Channel Interface Driver for Windows Server"
• Install "Agentless Management Service"
• Install "Advanced Power Capping Microcontroller Firmware"
• Update iLO 5 firmware to 2.47
• Install "Gen10 Service Pack for ProLiant version 2019.12.0"

Any ideas ot tips ?

Hope you have already referred following advisory:

https://support.hpe.com/hpesc/public/docDisplay?docLocale=en_US&docId=emr_na-a00083154en_us

addition to that

Please try to change Increased cooling Mode in the RBSU and check the status.

RBSU ->advanced Options->Fan and Thermal Options-> Thermal Configuration->Increased cooling Mode

Save and exit.

Hi,

According to the advisory I already installed "Agentless Management Service"

Setting the cooling mode to "Increased cooling Mode" in RBSU is actually making things worse, all fans at are 55%

Try to disable "Collaborative_Power_Control" and check.

Incase issue persist kindly share installed hardware and software information..

also

how about the ambient temperature ?

[Pierrot Robert]

Hi,

"Collaborative Power Control" is grayed out in RBSU

ambient temperature is my office, so around 20 °C

I have my ML350p Gen8 set to "Optimal Cooling". It's the best compromise I could find. "Increased Cooling" and especially "Maximum Cooling" is too loud.

What are your "Power Profile" and "Power Regulator" settings configured to?

[Pierrot Robert]

"Power Regulator" is at "Dynamic Power Savings Mode"

"Workload Profile" is at "General Power Efficient Compute"

[6BQ5]

Your power settings are lower than mine. My Power Profile is set to "Maximum Performance" and my "Power Regulator" is set to "Static High Performance". With E5-2697 V2 processors in my ML350p crunching SETI@Home the fans are running fast and loud..

Are you running any power hungry programs?

[Pierrot Robert]

I do not run anything except Windows Server 2019 right now. I want to solve the noise issue before I put the server in production.

A quick Google search :

It looks like you are not alone in your complaint about the volume of the fans. They probably prioritized running cool instead of running quiet.

Which processors are you running inside your DL20? I looked up pictures of that server and it looks like a tiny 1U high design. Those fans must be teeny tiny. So, in order to move enough air through the box those fans must spin and wail like cats overdosing on cocaine.
