R750XS, Windows Server 2022, After install Hyper-V, Reboot server: Fan run 100%
I have installed windows server 2022.
Everything works fine, After I installed Hyper-v and installed a virtual machine.
Everything is still working fine, but when I reboot the fan runs at 100% and won't slow down.
If I shutdown it and then turn it back on, it runs fine again

Hello,
Has anything changed on the server after purchase such as parts removed or parts added?
If so you may try returning to original configuration and testing.
Check and confirm you have all the firmware and drivers up to date.
Next try running the diagnostics to check for hardware issues.
Boot to <F10> and run the diagnostics. Note any errors and continue testing.
Try giving the server a flea power drain, reseat fans, then test a normal reboot check results.
drain flea power (shut down, disconnect power cables and Network cables, hold in power button 20 seconds with cords removed).
After flea power drain, system has to set for 3 minutes for DRAC to reset without any power plugged in
At this time reseat all the fans.
Then plug in NIC and power but wait 2 minutes before power on to give DRAC time to initialize.
Test a normal reboot after booting the server.
=====================================

We have 3 dell R750XS servers.
- The first one was bought half a year ago
BIOS Version 1.10.2
iDRAC Firmware Version 6.10.80.00
Everything works fine.
- 2 recent servers purchased 1 week ago:
BIOS Version 1.13.2
iDRAC Firmware Version 7.10.30.00
Both servers have the above problem.
I think the IDRAC driver has a problem.
We can downgrade it to: 6.10.80.00

I tried reinstalling only windows server 2022.
At this time plug in 1 network port.
Updated network driver, chipset, windows update to the highest version.
Everything works perfectly.
I plugged in another network port and when I rebooted, the problem occurred.
IDRAC fan control does not operate correctly when additional network ports are plugged in

Hi
I have the same issue.
I have two Dell PowerEdge 650XS servers (18 months old) and after doing routine firmware updates on 22/04/2024 using DSU PowerShell command, I've got an annoying new problem that didn't occur before.
When you reboot the server using the windows OS (server 2019) , on reboot the fans run at 100% permanently. How ever when you do a graceful shutdown from Windows OS, and then power on using the iDRAC the fans start normally, at 15% ish.
We've reported this to Dell support but dont have a hotfix for this yet, and they cant explain why this is.
I'm curious about the reported bug in new iDRAC firmware 7.10.50.00.
Please can you share more details so I can refer my Dell engineer support to the same issue?
