Re: HP ML350e Gen8 Fan Noise

[ Edited ]

It seems that there may be multiple fan-based issues described in this thread; both constant, loud fan noise and periodic cycles of "sirening" noise.

We had a server with the "sirening" variety of noise, this is the general config and how the issue was resolved.

ML350p Gen8, Server 2008 R2

Cooling set to Optimal

PCIe card - HP SC11Xe Host Bus Adapter - if the card is uninstalled the issue goes away

Steps attempted:

Applied SPP 2013 (current), all applicable updates

Applied array controller firmware 3.54

Reset iLO

Reset NVRAM

Unplugged server, left cold for 5 min.

 

None of these steps corrected the issue. I was then advised by HP support to make this adjustment:

From the RBSU, select:

Power Management Options > Advanced Power Management Options > PCIe Gen 3 Control

For the slot where the add-on PCIe card is installed, toggle the setting to Disabled.

 

While the SCSI HBA above is the recommended HBA for this server, ours was 6 years old and does not support the PCIe 3.0 standard. The server has been quiet since the adjustement was made.

Re: HP ML350e Gen8 Fan Noise

I am in the same situation with a new server here at work.

 

The point is, when I get into the RAID controller setup (which is, AFAICS, a Linux based environment) the fans slows down correctly. So I think HP may have kernel patches or other configurations around that never made into distributions and affect the ability to control fans.

 

This is really disappointing.

Re: HP ML350e Gen8 Fan Noise

It seems the lastest Firmware upgrade (SP62937) have some effect on the issue. The fan is still running at a fixed speed but at least it is a lower default so you can actually keep the server in the same room as you are...

Re: HP ML350e Gen8 Fan Noise

I had the motherboard replaced, upgraded to the latest firmware (J02 07/02/2013) and latest iLO firmware 1.30. Also added in a missing HD blank and the PCI fan baffle. This has reduced the fan speed (and noise level) from just above 50% to 30%. At 30% the noise is still noticeable but not screaching like before.

 

I read reviews that the ML350p G8 generates the noise barely above whisper level. There seems to be an issue with ML350e G8 model. If the 'p' version runs so quietly, why not the 'e' version.

 

This is a great server if not for the noise it generates.

 

HP, please pull your resouces and help identify the issue and resolve it.

Re: HP ML350e Gen8 Fan Noise

Hi,

 

Just a short status update for those who face the same problem as me.

 

I have the same "loud fan noise" problem with a HP ML350e gen8 server without any extension cards running SLES 11 SP2 xen kernel. Yesterday I installed the new HP firmware (BIOS), and the speed of the fans went down to ~30%. Still loud, but it is better than 57%. Then I installed the hvpsa kernel modul from HP altough I don not use the B120i controller, but the fans are still at 30%. The motherboard has been replaced months ago.

Re: HP ML350e Gen8 Fan Noise

Not sure if this will help, but i have a ML 350e Gen8 straight out of the box with the fan noise issue that you all appear to have. My solution:

 

F9 and go into bios setup. Find cooling which i think was in advanced and change it from increased to optimal cooling.

 

Fans are now at an acceptable level.

 

Hope this helps.

Re: HP ML350e Gen8 Fan Noise

Hey guys!

 

Did anyone solve the noise problem with HP ML350e Gen8? I'm considering returning mine as fans don't go slower then 29% - still not acceptable noise level for office space :/

 

Thanks,

Kamil

Re: HP ML350e Gen8 Fan Noise

[ Edited ]

We had success in sorting the fluctuating fan noise issue on a variety of ML350p Gen 8s

 

The fans now run at 6/27/27 which is acceptable for an office environment

 

It appears the Power Management Update  3.2 Sept 2013 Online ROM Flash for Windows x64 - Power Management Controller (HP ProLiant Gen8 Servers) sort this one out.

 

When conducted along with the latest release of the P72 system bios, the SmartArray v4.68 update and the iLO 1.32 update, the fan noise stabilises regardless of load

 

Sadly, the PMU firmware can only be flashed from a windows based environment, so those of you on ESXi like us will need to boot onto a Windows 7/8/2008R2/2012 install on a seperate disk be it in the RAID or as an additional drive plugged into the internal sata ports.

 

From testing, the fluctuating (and in fact, increased) fan noise will happen with pretty much any PCIe card put in the server regardless of settings. HP tell me the increased fan speed is by design due to increased airflow needed for expansion cards, but the fluctuating is a firmware bug.

 

Hope this helps!

Re: HelRe: HP ML350e Gen8 Fan Noise

Did someone already found a compatible USB 2.0 or 3.0 PCI-E card which doesn't increase the fan speed?

Does HP have this cards and what are the partnumbers?

 

I use a HP Proliant 350e G8 and the fan speed increases from 6% to 25 - 30% if I install a Startech 4 port USB 3.0-card (PEXUSB3S4V).

Re: HP ML350e Gen8 Fan Noise

Also experencing this issue on server,

 

We have installed a P410i RAID card and installed all updates as suggested by HP Tech Support.

 

This update has also been installed with no effect - 

 

As per the design the Gen8 servers tend to speed up the fans in case there is a PCI card installed.

This happens as the normal flow of the air is obstructed causing the fans to run at higher RPM for optimized cooling.

 

As per the report I can see :

    5     4x/x4     PCI-E Slot 5      PCI Express Gen2 x8   HP Smart Array P410 Controller

 

Which could be a cause of the issue reported.

 

Advised is to

> ensure we are running the latest firmware for the HP Smart Array P410

> Controller

 

* RECOMMENDED * Online ROM Flash Component for Windows - Smart Array P212, P410, P410i, P411, P711m, P712m, and P812

 

By downloading, you agree to the terms and conditions of the HP Software License Agreement.

http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/psi/swdDetails/?sp4ts.oid=3883931&sp...

 

 

 

 

 

After this update made no difference we went back to HP and got the following reply - 

 

Issue : High Fan Speed

I had a detailed discussion with the Senior Engineer and they have also confirmed that the steps that we performed so far were the only work around for this issue.

As per the design the Gen8 servers tend to speed up the fans in case there is a PCI card installed.

This happens as the normal flow of the air is obstructed causing the fans to run at higher RPM for optimized cooling and also they are designed to be used in  data centers .

 

 

I am yet to give up hope as we have a few of these servers out in the real world and would like HP to address this option rather that assume these servers as all in DataCenters around the world.

Re: HP ML350e Gen8 Fan Noise

Hi we are also experiencing this issue on a HP ML350p Gen 8 Server, this started when we added two new hard disks and changed the RAID configuration from RAID 5 to RAID 1+0, we have ESXi VMWare vSphere 5.5.0. Besides our disk controller is the P420 Smart Array 1GB FBWC, in our case the fluctuation happens when the temperature sensor for "Disk or DiskBay 1 08-HD" start to increasing without any logical reason from 35 celcius grades (normal temperature) up to 52 celcius, then the fans are elevating till 99.49%, the problem in our case is a system degradation due to a high DPC (Deferred procedure call) Queue by second in processor. We just have SQL Server 2008 R2 in a Windows 2008R2 virtual machine, so the big problem is impacting our transactional system. So if you think we have a very related issue I will appreciate you sharing more information with us.

Re: HP ML350e Gen8 Fan Noise

My experience...

 

We have a dozen clients with new ML350e Gen8 servers. A couple of them required add-on cards like USB 3.0 or eSata connections. Although it would be nice of HP to include at least USB 3.0 on these servers natively, we find other options for small businesses who can't afford more expensive enterprise equipment. 

 

Anyway, we have updated ALL firmware to the latest version as of this posting. The only change from a stock server (using HP brand drives) is the addition of a PCIe card in the top slot (can't recall which number).In addition to the firmware updates I have tried every other suggested solution in this post to no avail. That includes the latest power management firmware, PCIe Gen3 Control and the correct thermal settings in the BIOS (Optimal). These particular servers have only a single CPU and no additional fan kits. Before adding the PCIe cards the fans where whisper quiet. 

 

Fans have the same behavior on both machines in questions, typically between 29% & 36%

 

It seems none of the fixes suggested here work for us. I sure hope HP listens and releases a full fix via BIOS, which seems to be the only solution.

 

Thanks all

Re: HP ML350e Gen8 Fan Noise

Dear Marin_uk

I don't know if this has been adressed yet, seeing i didn't scroll through the entire thread but this is an advisory released by HP which might help : http://h20566.www2.hp.com/portal/site/hpsc/template.PAGE/public/kb/docDisplay/?spf_p.tpst=kbDocDispl... .

Kind regards

Re: HP ML350e Gen8 Fan Noise

We have fixed our issue!!

 

I wanted to update everyone with an update that fixes the issue for us.  After following everything on here and other sources we had another look at the board and the onboard Raid Controller.

 

We noticed that our model had the option to install a  Smart Array Flash Backed Write Cache (512MB) (p/n -631922-B21)

 

We have since purchased this and installed it into our server ...... fans now running at 8-10%.   We have removed the other raid card installed and the system is up and running without issues.

Re: HP ML350e Gen8 Fan Noise

Incredibly mine stopped making noise after I updated the whole firmware as it went from 75% to 43%.

I also disconnected the Ambient temp connector!!

 

Now I disabled the PCI Gen 3 in Advanced options and I am at 6%!!

Re: HP ML350e Gen8 Fan Noise

Like others I've experienced the fan noise issue:

 

http://www.mikelaverick.com/2014/01/return-to-the-homelab-part2-hp-ml350e-gen8/#more-4947

http://www.mikelaverick.com/2014/02/return-to-the-homelab-part-4/

 

In the end I raised a support call with HP. They told me this is a known issue with non-HP Parts. The suggested I did firmware updates, but if these didn't work it wasn't their problem but mine. As I suspected a firmware update and tinkering with the BIOS settings had zero or nominal effect - when compared to disabling my Intel Dual Port Cards. 

 

The moral is never fit anything to a HP server that isn't from HP because the warranty T&C will invalidate any further support and you'll be left with the "this is a know issue" response. Who'd a thunk that, I niavely thought PCI was an industry standard?

 

Anway, throughout my research I remember someone saying that it was possible to disable the thermal detection on the PCI bus by some jumper/cable-pull on the motherboard.

 

For the life of me I can't find that in my search history, nor can I find a suitably detailed circuit layout to attempt this workaround (yes, I'm aware of the risks...) The alternative is yanking out the card, ebaying them and then giving HP even more of my valuable cash...

 

Regards

mike

Re: HP ML350e Gen8 Fan Noise - keeps happening - there must be a serious problem with these servers

We have a server which has had its mother board replaced 3x times.  Problem of excessive fan speeding and then servr crashing keeps happening.  The server is 100% HP with the latest firmware, so we are just left in the lurch - cannot HP take this seriously and investigate properly, and stop just replacing motherboards, as this does not cure the problem.  It is obviously something more deep that needs urgent tracking down.
