Hello,

The iDRAC functions as the fan controller for the server. I would recommend restarting the iDRAC to see if that helps. You can do that through command line using "racadm racreset" if OpenManage Server Administrator or RAC tools are installed. Alternatively, you can also shut the server off, unplug it from power, then hold the power button down for 30 seconds. 

If the fan still spins high, you can swap the fans to see if the issue follows the fan, or the location on the board.

Can you also ensure iDRAC and BIOS FW are upto date and check the behavior.

I have reset the idrac from the administration panel, following these same steps: https://www.youtube.com/watch?v=9HAeUAXXpag

and I still have the same problem

the version of the BIOS is up to date:

Hi,

Usually, when fans run at full RPM, this is because the iDRAC is out of date. This is because iDRAC is the feature that controls fans. Could you update also iDRAC? via link https://www.dell.com/support/home/en-us/drivers/driversdetails?driverid=xdxnf&oscode=ws8r2&productcode=poweredge-r710 Mostly cases iDRAC FW is resolve that fan issues unless there is a hardware error.

Also, you can check C1E state in BIOS. When C1E is disabled in the system BIOS, the fan RPM has to be increased to ensure the long-term reliability of these processors. When the C1E deactivation feature is not required, use the Custom profile and enable C1E.
