While the tempeture still at below 60C I don't think there is a reson for the fan to run at such high speed.
Are there any thing that I can do to solve it? The fan has been run at 94% for a few days .

Get the below changes done in RBSU:
System Configuration > BIOS/Platform Configuration (RBSU) > Advanced Options > Fan and Thermal Options >Thermal Configuration>Optimal Cooling

Check the status now.

If it is already set to "Optimal Cooling" change the cooling mode to "Increased Cooling." and check for issue resolution.

If still issue perist shutdown the server
Drain the flea power by disconnecting any power input, all the external cables (including Power and Network), external devices and pressing and holding down the power button for 10 seconds.
Check the fans and be sure the air flows over the drive.
Reseat the fans. Also reseat any PCI cards if connected.

The following steps may be performed to clear NVRAM using the system maintenance switch on the system board:
a. Extend the server from the rack, remove the access panel, and locate the system maintenance switch (refer to item 1 in figure 1 below).
b. Move switch S6 from default 'Off' position to 'On', install the access panel and connect the power cable to the walljack and power it on.
c. When a message indicates that a maintenance switch has been turned on and the unit has been reset, power it off, remove the power cable from the walljack. Remove it from the rack,
remove the access panel and reverse switch S6 to 'Off' and then power the server back again.

Connect power cables again and see if the server behaves normal.
If still same issue reduce the server to minimum configuration.
Remove all external PCI cards attached to server.
Start adding parts in incremental manner to isolate the faulty component.

I work for HPE

Thank you for the help !   I tried to change to increased cooling and reboot, nothing changed. But after unplug the power cable for 10sec and reboot, the fan won't run at full speed any more.

Hello, @twtaps_school 

Just want to let you know of a much simlper solution.  Simply login to iLO and select "Cold Boot".

That will do the trick, no need for any more trouble.  This is always needed after firmware flash, it's on the documentation.

I appreciate this ticket is now fairly old but wanted to add to the thread for any future viewers.

Having recently (back in January 2020) purchased a DL380 Gen 10, we experienced the same issue shortly after installation, following a reboot - in our case, 4 fans running at 94% and the other 4 running between 40 and 50% Following 'flea power release' steps did resolve and we did not encounter the issue again until yesterday when, following a reboot, we were back up to 94% fan speed. It appears HPE have released an update back in April to address this in the form of Innovation Engine Firmware release Specifically for us, the CPU temperature was not listed in the iLO interface temperature panel suggesting it couldn't read the value.

Windows release for :

As per the release notes, you do need to complete a reboot following the extraction to initiate the update.

If not already installed, the Channel Interface Driver. will be required. As always, worth checking for future releases before updating.

Cheers. You solved an issue we had with a client.
