The Wiert Corner – irregular stream of stuff

Some combinations of hardware/OS will result in high FAN speed despite low power usage on Dell R730/R730xd systems.

For me, altering the BIOS or iDRAC thermal settings did not solve it, nor did updating all firmwares to the most recent versions, so I went digging further.

Below are some links in case I want to resolve that (after figuring out that Dell R730 and R730xd are 13G systems).

There are lots of quotes in them as it will help me find back the information later on.

Note to self: I really wonder what the difference between raw 0x30 0xce and raw 0x30 0x30 is (I think 3rd party PCIe support and forced fan speed level) and how they differ from the system.thermalsettings.ThirdPartyPCIFanResponse setting.

1. Install [Wayback/Archive] Dell EMC OpenManage BMC Utility,v9.1.0 | Driver Details | Dell Singapore
   

   Dell BMC Utilities accompany Dells Baseboard Management Controllers (BMC) to extend their remote management and scripting capabilities. Included in the BMC Utility package are Serial Over LAN Proxy (SOLproxy), IPMI Shell (IPMISH), and the Open Source IPMI Tool. The SOLproxy allows the servers serial console to be redirected to a remote client. IPMI Shell and IPMI Tool allow local and remote IPMI management of a server.

   On other operating systems, you can also install any package containing a recent version of the ipmitool.

2. Follow steps from [Wayback/Archive] How To Disable The Third-Party PCIe Card Default Cooling Response On PowerEdge 13G Servers. | Dell Singapore
   

   Symptoms

   The default automatic cooling response on PowerEdge 13G server for third-party PCIe cards provisions airflow based on common industry card requirements. Our thermal algorithm targets delivery of maximum 55C inlet air to the PCIe card region based on that industry standard.

   For some cards may not need additional cooling above the baseline (such as ones that have their own fan), Dell has enabled an OEM IPMI based command to disable this default fan response to the new PCIe card.

   Note that the ability to disable this feature only removes the fan response associated to the addition of third-party PCIe card and does not compromise original thermal algorithm based cooling needs. If the fan speeds were already high due to other system needs, then disabling this feature may not have an effect.

   Resolution

   ENABLE/DISABLE Third-Party PCIe card based default system fan response:

   1. Download and install OpenManage BMC Utility.
   2. Enable the “IPMI over LAN” in iDRAC of the target machine, this can ben done via iDRAC Web GUI or BIOS Setup.
   3. Go to the installation folder of OpenManage BMC Utility, run the following commands:

   Set Third-Party PCIe Card Default Cooling Response Logic To Disabled
   ipmitool -I lanplus -H <IPADDRESS> -U <USERNAME> -P <PASSWORD> raw 0x30 0xce 0x00 0x16 0x05 0x00 0x00 0x00 0x05 0x00 0x01 0x00 0x00

   16 05 00 00 00 05 00 00 00 00 (Enabled)

I found these via a few other links below:

• [Wayback/Archive] Tell me there are more silent fans for a Dell R730xd server, please! : homelab
  

  You can control fan speed with ipmi tools.
  Also, there’s some BIOS settings. I can’t recall details, but mine only bursts the fans to about 50% speed for < 1 second on bootup so I must have changed a setting there :)

  I added a boot script to my R720 to use ipmi tools to set fan speed to about 12% – the server is next to my wife and she doesn’t complain, so you know it’s as quiet as normal PC.
  As for temps, I ran extended benchmarks and the CPUs got into the 60-65C range and was stable there, so I’m not concerned about monitoring temps and varying fan speeds.

• [Wayback/Archive] Dell PowerEdge fan control with ipmitool – individual fan speeds : homelab
  

  I couldn’t find any info about this here or elsewhere on the internet, but I was playing around with ipmitool today and figured out how to control PowerEdge fans individually (at least on my T630).

  The command to turn on manual control is:

  ipmitool -I lanplus -H $IP -U $USER -P $PASS raw 0x30 0x30 0x01 0x00

  and to turn it off is:

  ipmitool -I lanplus -H $IP -U $USER -P $PASS raw 0x30 0x30 0x01 0x01

  Controlling all fans at once can be done with:

  ipmitool -I lanplus -H $IP -U $USER -P $PASS raw 0x30 0x30 0x02 0xff 0x##

  where ## is 00 to 64, which is mapped to 0% to 100%.

  All the above info is available all over the place, but it turns out the same command can be used to target individual fans too:

  ipmitool -I lanplus -H $IP -U $USER -P $PASS raw 0x30 0x30 0x02 0x?? 0x##

  Where ?? is a zero indexed fan number and ## is as above. Fan 1 is 0x00, fan 2 is 0x01, etc. If you use a an incorrect number it will throw an error on ipmitool and not cause any damage.

  I needed this because my computer has different fan zones, and I wanted the CPU zone to have a lower RPM than the PCIe zones, and now I can. Much quieter.

  I hope this is useful!

  I’ve developped a little Docker container based on someone else’s to set manual fans speed and monitor CPUs temperatures. Don’t hesitate to check, use & help : github.com/tigerblue77/Dell_iDRAC_fan_controller_Docker

  …

  To my knowledge they all mention controlling fans, but none of them show how to control each fan individually. They all use the 0xff parameter which sets the speed for all the fans at once. Using 0x00 to 0x05 allowed me to set each of the 6 fans to different speeds.

  Or even easier, just SSH to the idrac interface (same credentials) and run this racadm command:

  Works great on my R420’s, though I believe they removed this feature for the x40 generation….

  Also, make sure your pcie cards can actually handle low airflow. It’s not a problem for my Mellanox Connectx-2’s (they barely hit 50-60c in a PC case with no direct airflow), but other cards (HP 10gbit controllers come to mind) might start to get a bit crispy with this method. Also be wary of anything with batteries close to the heatsink like RAID controllers.

  …

  Thanks for posting this. I ran into this solution just recently as well. I’ve been meaning to make a post since the only thing I’ve found on here was to use static fan speeds.

  I’ve found this to work on my R320 and R520. For those servers, it looks like you need at least IDRAC version 2.x.x or higher for the command to work.

  On the R520 with a Mellanox connectx-2 and a P400 gpu, with 3rd party response disabled and idrac version 2.10.10, fans will go down to 10% (under 3k rpm) and it’s pretty quiet. Going past 2.10 will have the fans go to 30%.

  On the R320 with just a connectx-2 card, fans go down to 8% even with idrac updated to 2.60.

  • [Wayback/Archive] Add undocumented Dell OEM fan control commands · Issue #30 · ipmitool/ipmitool
    

    As is well known in /r/homelab on reddit, there are some OEM commands for (at least) the 11th Gen Dell PowerEdge servers which can be used to alter the fan control.

Then, of course, it’s the matter at hand – these are undocumented and entirely unsupported by Dell, and could possibly damage hardware, even. It doesn’t feel right to mix them with the rest of the commands.

    so I have tested my r710 and can confirm that 0x00 is 1200 rpm, 0x64 is 12360rpm and 0x01 through to 0x64 ramp up as they go up. 0x65 has no effect and error’s. 0x0a is 2160rpm and is about as quiet as my dell optiplx7010 and a fridge/freezer.

    The hex values correspond to PWM %. 0x64 = 100 in decimal. This works down to the minimum fan speed. This is where it can get dangerous. Some users in reddit posts reported setting the value too low turns the fan off which can lead to heat related failures.
    On my Dell R720xd 0x64 is ~17500RPM, 0x1a is ~6000RPM, 0x14 is ~4900-5000RPM, 0x0a is ~3300RPM, 0x05 is ~2500RPM. My fans show a minimum speed for 960RPM which looks like that’d be around 0x01. I don’t want to set them to that speed at this time and I don’t think anyone else would either.

  Q

  I have a pair of Broadcom NetXtreme 57711 10GbE cards. I put one in a Dell R710; it boots with the card fine, the OS (CentOS 7) recognizes it, and all seems well. However, when I put the other card in an R730xd (also running CentOS), something unexpected happens: the R730xd’s fans kick into high speed as soon as the system starts to boot the OS, and run continuously at high speed no matter what is happening. The fans do not run at full speed when interacting with the Lifecycle Controller or the BIOS screens. They only start spinning at full speed when the computer starts to boot the OS and before the OS comes up, so it doesn’t seem to be a function of the OS.

  I’ve updated the R730xd’s firmware to the latest versions available, I’ve tried setting the CPU performance profiles in the BIOS, and I’ve tried setting the thermal profile in the iDRAC, but nothing seems to change the behavior; the system always goes into full-on jet-engine mode. Googling reveals at least one other person encountering similar fan behavior related to adding a PCI card to an R730xd (though it’s unclear whether it’s the same card – it doesn’t appear to be).

  What am I doing wrong? More importantly, can this behavior be changed, so that the fans do not stay stuck at full speed?

  A

  Dell hardware that ships with a server as a configured item – which IIRC those broadcoms where – is almost never comparable between generations. Dell tends to put custom firmware that hooks into all their management systems on these things.

  So the short of it is the part is probably not comparable, won’t be supported, and will cause weird issues like what you are seeing.

• [Wayback/Archive] Noisy Dell R730XD : homelab
  

  Before I added all my components that trigger high fan operation (both 3rd party PCIe devices, as well as non-Dell SSDs), mine would go down as low as 20% (the minimum it will go without manual IPMI controller), whereas yours are humming along 53%. That’s roughly what mine was doing when I first put in my PCIe risers for NVMe drives and it started spinning up high.

  I use https://github.com/spacelama/R710-Fan-Control/ on my R730XD, as I have non-Dell SSDs installed and it’s the only way to keep fans below 60%. You need to enable the virtual network interface for iDRAC to be connected to directly from your running OS, otherwise you will need to setup a user for the script to connect as over your regular network.

  There is another I’ve seen floating around since back then called the “Poweredge shutup” script as well 😂 no experience with it but it seems solid.

  It may be worth looking in the event log of your iDRAC for everything since you put the Quadro in, sometimes it has useful tidbits.

  Also possible it’s still doing the “third party PCIe device” reaction if your Lifecycle controller hasn’t run a inventory of your server since before you removed the Quadro. If you don’t have it set to do it at every boot, you might need to re-enable that temporally. I don’t recall if you can ask it to do it for a single reboot, or if you need to re-enable doing it every boot and then disable it again…

  I have new server Dell t430 2 xenon e5-2640v3 64gb ram, 2x 1TB samsung evo 850 ssd and 2x Intel PCIE p3500 400gb ssd. When I installed Intel PCIe ssd server fan ramp up to 80% and is very loud. I tried changing fan profiles to low fan speed and it did not help. Then I tried disabling third party PCIe device fan response, still same speed but iDRAC now shows 4200 rmp instead of 10080 rmp. iDrac logs shows that PCIE ssd was detected normaly and no further action was required. Fan speed goes back to normal only when I uninstall these pcie ssd. Ordered external fan from dell, maybe it will help a little I don’t know what to do anymore. Help.

  [Wayback/Archive] Dell Fan Noise Control – Silence Your Poweredge : homelab

  there were some threads complaining about server noise in this sub the last days. I did some research on how to manually controlling the PowerEdge fans.

  I read threads on this sub and other boards and found a lot of commands. These are already widely known, but I wanted to list them again. Maybe they will help others.

  I tested them with my R210II, T620 and T330. So basically a 11th, 12th and 13th generation PowerEdge. Although you might have to change the sensors’ names accordingly.
