The motherboard (a S2600CP4) is preinstalled in the system, so the cabling should be correct.
When I first turned the system on. both fans ran at hight speed. After doing the firmware update, the top fan (Fan 2) is running correctly. But the lower fan, which I believe is fan 1, is still running very fast.
I have updated the firmware using the EFI a second time.
When updating the FRU, I see the following messages.
The system detects the Intel Server Chassis P4000M Non Redundant Fan SKU is detected,
8 x 3.5 Hot Swap Backplane 1 is deteced

Do you want to update the chassis info area of the FRU? I choose "N"
Do you wan to enter the chassis manufacturer name (Additional Field 1)? I choose "n"
Do you want to update the system info area of the FRU? I choose "n"
It does show FRUSDR update completed.
When I go into the BIOS under System Information I see: BMC firmware revision 1.22.6890, ME Firmware rev. 02.01.07.328, SDR rev. SDR Package 1.11.
I have played around with the System Acoustic and Performance Configuration, but those changes did not make any difference.
Any suggestions would be appreciated.
You have covered most of the troubleshooting listed in our article http://www.intel.com/support/motherboards/server/sb/CS-022809.htm "System Fan runs Too Fast or Too Loud". I would recommend inspecting the installation of the side cover to make sure it is properly mounted. If it is, I would recommend recording the logs of your system using our https://downloadcenter.intel.com/Detail_Desc.aspx?DwnldID=24237 Intel System Information Retrieval Utility to investigate what might be triggering the fan speed.
