This will help the fans. Let me know if it helped.

Hello, this was one of HPE's solutions. Other solutions were to
update/downgrade different drivers and go back to previous versions of
the BIOS. They are all done.
The problem is that the fans make less noise (more than a Gen10) but
they do not ventilate the processor enough.
They frequently accelerate for a few seconds with a consequent increase
in noise.
The processor easily exceeds 70ºC without workload.
With workload it has reached 91ºC.
Thanks.

Yes,  i can confirm,  i have taken the bios back to 1.46 and the fans work fine and are not excessively Loud,  however the CPU without any load runs between 55 and 71 at the moment,.

[Rihan]

I think everyone needs to Raise a Support Ticket to HPE. I have applied AMS Update (https://support.hpe.com/connect/s/softwaredetails?language=en_US&collectionId=MTX-ada99fb833d94a8b )to a few of the servers and they seem to be okay for now.  Also i belive setting up the Servers using Inteligent Provisioning also helps.

Confirmada la solucion con la version de la Bios 1.46

Google Translated: 

Solution confirmed with Bios version 1.46

[Richard Brindle]

Yes,  i can confirm,  i have taken the bios back to 1.46 and the fans work fine and are not excessively Loud,  however the CPU without any load runs between 55 and 71 at the moment,.  I have installed all the software and drivers that everyone on the forum suggested,  basically 2 options

bios 2.12 and bios 2.16 server sounds like a jet engine even when server has booted up and it quietens down after 4-5 minutes occasionally this has not happened and had to reboot a second time.

bios 1.46 fans runs normally but CPU temp is out of control when there is a load on it,    just need a happy medium

[Rihan]

@Richard Brindle Have you tried running the LAtest version of AMS?

I have put the servers on 2.16 and ran the latest Version of AMS and it has helped.

Let me know if that helps .

He aplicado TODAS las soluciones del foro, que son las mismas que me han dado los tÉcnicos de HPE. Tengo el caso abierto desde hace un mes.
La solución es dejar los ventiladores con bajo nivel de ruido y añadir un ventilador de 7 cm (para poder poner los conductos de ventilación) detrás del disipador del procesador. De ésta forma la temperatura se mantiene 20ºC por debajo de la que tiene normalmente. El problema es que no hay dÓnde fijarlo ni de dónde obtener la corriente (tengo el ordenador tumbado con el ventilador posado en la parte trasera del disipador y la corriente de una fuente externa).

I have applied ALL the solutions on the forum, which are the same ones that the HPE technicians have given me. I have had the case open for a month. The solution is to leave the fans at a low noise level and add a 7 cm fan (to be able to put the ventilation ducts) behind the processor heatsink. In this way the temperature is maintained 20ºC below its normal level. The problem is that there is nowhere to fix it or where to get the power from (I have the computer lying down with the fan placed on the back of the heatsink and the power from an external source).

[ISL1]

So I've been working with HPE Support and they have replied with.....

"I have worked with our ERT team, and they have suggested is it not advised to run the server without the air baffle. Also Our ERT team is already aware of the issue and currently working on a solution for the same.  So we will continue working with our ERT for a solution on the same, and share updates on the progress. "

So they know there is an issue with the air baffle design and none of the solutions given work at all.

The whole issue is down to a design flaw with the air baffle which I raised with them when opening the call.

No fix in the pipeline, 

[pmrgoncalves]

This is completely ridiculous...

Setting up a new HP110Gen11, it comes from factory with bios v2.12, boot it up and the noise is horrible.

Did a upgrade to v2.16, still the same issue...

Sold one a few months ago and had the same issue, at that time I had to downgrade bios, as told here, to version 1.4x.

So after this time HP still have not solved this issue, that is really competent from HP...

As for the current one, just downgraded it to 1.46 and it is running normally, as it should.

I think HP should test these updates before sending hardware to customers.

[Alexg60]

Same issue here. Been back and forth with HP support, collected logs, ran the updates and nada. 

[Malte3]

Downgrade to BIOS v1.46 has resolved the issue for me so far.

[RobertoFC]

Sí, volver a la versión 1.46 de la BIOS reduce el ruido, pero también reduce la ventilación. En "reposo" la CPU llega a los 70ºC, con carga de trabajo los supera con mucha facilidad y se acerca a su máximo de 93ºC. Tengo abierta incidencia con HPE por esta ventilación deficiente, que han elevado a un ingeniero de nivel L2, pero no dan respuesta.
El servicio de HPE es bastante deficiente. La solución es añadir ventilación adicional. Ya estamos buscando servidores de otras marcas.

Yes, reverting to BIOS version 1.46 reduces noise, but it also reduces ventilation. In "rest" the CPU reaches 70ºC, with workload it exceeds them very easily and approaches its maximum of 93ºC. I have an open incident with HPE for this poor ventilation, which they have escalated to an L2 level engineer, but they have not responded.
HPE service is quite poor. The solution is to add additional ventilation. We are already looking for servers from other brands.

[art76]

Keep in mind the SPP updates are usually not the latest updates within, and can be a few weeks/months old already. So searching and finding the individual updates at HPE support will get you the latest.

I believe the firmware update from F10 also uses the SPP as its source in the background, as we've found it showing updates that were lower version numbers on some new servers.

[art76]

For reference, tested on a brand new ML110 Gen11 (Xeon Gold 5416S) over the last couple of days. In a cool room, probably about 20c in there.

Factory BIOS v2.16 and server sitting with 3x SSD's installed, and waiting at Server 2022 install screen observed (actually heard from another room), Fan 1 - 23%, Fan 3 - 80%.

Updated BIOS to latest, v2.20, same everything else, Fan 1 - 20%, Fan 3 - 67% (CPU 40c). Quieter, but still loud enough that if you were in same room it would be annoying.

Updated iLO to latest, v1.59 just in case, no change. Update SPS to latest 6.1.4.47, no change.
Changing fan settings to maximum cooling, rebooted, changed back to Optimal cooling, rebooted, no change, high noise/flow.

Installed Server 2022. No change, noisy.

Using SPP, installed Agentless Management Service and after a reboot, the server is running quietly, 52c, 7/8% fans.

Ran Prime95, getting up to 100% CPU usage, and fans came up to about 10/33% and CPU to 80c, but you could have that in the same room and be OK with it. Left Prime running for a while and got up to about 83c, and fans 11/36% but still ok.

Rebooting server and it is 30/70%, and then after windows loads a few minutes later, back to 7/9%, quiet, CPU at 60c.

Keeping an eye out for any newer BIOS or SPS or other firmware to see if these will ever be quiet without loading software into the OS like the Gen10s were.

[ISL1]

After long ongoing case with HPE we have had a full refund.

Findings that with the Air baffle, there is not enough airflow to the core components, mainly the CPU

Temperatures on CPU is over 80C which with these temps the fans try to compensate by raising randomly and annoyingly.
Without the baffle the fans are quieter, but findings here is all temperatues on core components are very high and not recommended to run without it.
Keeping fans running at 23% in ILO seems to be the sweet spot for temperatures to be acceptable with CPU steady at 74C, but with this the fans are constant in the background and not really acceptabe in office environment.

HPE ERT team and level 4 team have kind of admitted there are issues with this Fans / Temperature issues and have no real fix.
This issue is a design flaw and with the inadequate air flow to the system and until this is addressed, none of the recommended actions are appropriate and is not a technical problem that can be resolved with bios updates etc

[Richard Brindle]

Mine is now in production,  using bios 1.46 and all latest drivers,  cpu is resaonable steady between 55 and 65,   the fans do spin up very regaular for a few seconds,  i have had to put the server in a separate room from the main small office,  i am hoping HP are going to design and ship out new Air Baffle's,

[NunoR]

Hello

As far as I nkow, the model is still available for purchasing. Will HP remove it from the market? 

[ISL1]

Hi Nuno

Unsure if they will as depends how much noise they get on this.

IMO it will only really be an issue with the Server in Office environments with no Server room, so may not be enough to pull form the market

[GLSoft]

Hello all,
Running my new ML110 G11 with BIOS 1.46 and all others fw + drivers up to date.
And now it seems to be OK.

But I think it will be my last buy with HP.

Thx to everibody in this channel

[RobertoFC]

Hola, efectivamente todo parece OK.... hasta que revisas la temperatura del procesador y ves que tienes una parrilla marca HPE.

Hello, everything seems OK... until you check the processor temperature and see that you have an HPE brand grill.

[AlexGaab]

En realidad estoy teniendo un problema y aun más con el tema de ruidos del ML110 GEN 11 podrían ayudarme ya que es un problema realmente molesto en que la marca debería apoyar, he intentado de todo, el hardware esta bien, he enviado los logs sin embargo no estoy recibiendo un asesoramiento adecuado

Google Translated: 

I'm actually having a problem and even more so with the noise issue of the ML110 GEN 11. Could you help me since it's a really annoying problem that the brand should support? I've tried everything, the hardware is fine, I've sent the logs, however I'm not receiving adequate advice.

[Mr_Techie]

@AlexGaab 

Good day! 

Refer the response shared here: https://community.hpe.com/t5/proliant-servers-ml-dl-sl/hp-proliant-dl20-gen-10-plus-fan-noise/m-p/7215791#M187088

This might help you. 

[GLSoft]

Hello,

Did somebody try this ?
Any other news from HP ?

Possible to buy very 'silent' fans and not F35 reactors ?
From HP or others ...
