I have the same issue with a Lenovo D10 workstation equipped with a Intel 5000 chipset. I've been working with Lenovo for 3 months now trying to find a solution. In our research we found that simply rebooting the machine will "reset" the fan control circuit so it returns to normal operation. The cause of the problem on the Lenovos seems to be something to do with the way the motherboard senses the internal temp of the case. It's possible your server is experiencing the same issue and it's a Intel chipset issue. Lenovo has found the fan issue exists on a wide number of workstations, but most users don't experence it due to the fact that it requires the ambient temp inside the case to climb while the machine is in standby. I experience the issue randomly and rebooting or going back into standby and exiting again corrects the problem. Lenovo also discovered that it's possible to incorrectly connect the fans to the motherboard causing them to run at 100% power instead of automatically based on the motherboard control. Double check the fans are wired up correctly. If neither solution works, the last resort measure Lenovo came up with was to perform a recovery BIOS flash to completely reprogram the chipset in case it was corrupt.
When the fan are spinning too loud, it can be due to:
1. Wrong system fans are connected on the board.
2. Incompatible chassis and wrongly configured SDR.
3. Compatible chassis with a wrongly configured SDR
4. Bios Settings wrongly configured.
I will personally try to check if the chassis is on the compatibility list and the system fan headers are correctly connected and then update the following:
The recommended upgrade method, if not updating a hot-swap controller (HSC), is:
Reboot, and verify BIOS settings
The recommended method with an HSC(backplane) is:
Reboot, and verify BIOS settings.
After the update of these firmware, i will go onto the bios and Advanced, System Acoustic and Performance Configuration, Throttling Mode set to Open Loop,
Set fan profile as Acoustic and Altitude set 300 or less.
Other than this, next steps will be to verify the sel log and verify the release notes of the firmware if there is anything mentionned.
Hope these are useful,
As suggested by Aryan in the last post, do check all the possibilities. I have looked into many complaints on SR2520SAX that has a S5000VSA (value series motherboard) in it. What people usually do is, they update FRUSDR, select the Acoustic option in BIOS and even set the altitude however they would not be a little careless in referring to the motherboard manual to see if all the connections are properly made. One such system that initially spun our heads had the FRUSDR updated with the correct chassis specified, altitude and acoustic settings customized accordingly with all the ducts properly installed but as soon as the fan connection was made in the right place, the noise drastically reduced. I'd advise you check all the possibilities that Aryan has suggested and if you still fail, post a supporting JPG of your BIOS configurations and fan connections so that we are further able to assist you.
Thank you and have a nice day!

Many thanks for all your replies. We actually did exactly what Javed described but we also did a quick check on the fan cabling (with the idea in mind that intel will surely have done it right). From your comments I see that we definitely need the double check the cabling.
The server is actually in production state and I'll will only have a chance to check your suggestions early next week.
So far thanks for your help Douglas, Aryan and Javed. I will post if we found the cause of the noise.
Hi Arayan and Javed
The problem is with the loud fans is still there. We got only one chance to work on the server in the mean time. We checked (and touched) the fan cabling but that did not help.
We are using Windows 2008 Server Standard (64bit edition).
The next step was to run the intel one boot flash update utility (flashupdt) once again. That actually did have a great effect at the moment. At the very end of the update process of flashupdt, the fans did reduce its speed dramatically. We were very happy at the moment. We then restartet the server and during the boot process the fans also reduced its speed and noise. Very late in the boot process of windows 2008 (in german its named "Systemeinstellungen werden übernommen" on the screen which means something like "applying system properties") the fans started to run in full speed and on full noise level again and never reduced its speed since. Another reboot did not change anything.
Thanks a lot, disabling the IPMI-service did the trick. The server runs with reduced fan speed now. Everything seems perfect, as far as I can tell.
I hope that we can leave the IPMI-service disabled.
Here are the answers to your questions:
- The system LED was amber before but is now green
- We had two critical messages in the SEL saying that the fans were in critical low state (and two warnings that the fans are in low state and going lower). Now the log has no more warnings or critical entries.
- We did install Intel System Management Software (Intel Active-System-Console 3.0)
- We did not update any management pack from Microsoft
Thanks for all the help.
Now i will explain to you where does the problem comes from? This is from my opinion - nothing documented :-) Windows 2008 has its own IPMI driver
which conflicts with the Intel System Management Software IPMI driver. Actually this is due to the Windows 2008.
When the system LED is green, it means everything is OK. Amber can be due a couple of reasons like redundancy failure, system fans problem etc.
Anyway, i am glad that i could help you in a certain way - as an advice check on Microsoft website and Intel Website if they mentionned something about it.
