Tower Plus EBT2250, Bios fan settings in sleep mode
<Moved out of old XPS Desktops board and into new system Dell Pro Desktops board. DELL-Admin>
I recently purchased a Tower Plus EBT2250 in which fan speed increases when in sleep mode when there no activity such uploads or downloading and makes very little difference when thermal fan settings are changed to quite mode. No available updates and scan preformed are not indicating outdated drivers on Dell Support Assist. Fans seem to whirling up and down and stop to quite when PC is waken up.

The fans are running while the whole computer is asleep, or you mean while the monitor sleeps?
Personally, I never use Computer Sleep-Mode or Hibernation with my desktops (as they are plugged into the wall).

@sergio.rueda ,
Well then, that is not actually Sleep-Mode at all.
That is usually just Windows-11 doing File-Indexing, Anti-Virus Scans, Windows Update agent or other routine maintenance tasks while it's ON, but it can tell you are not actually using it.

@Tesla1856 It seems odd that fans are heard through out whirling up and down as soon as the monitor goes to sleep and when awaken fans as all of the sudden are quiet. I would understand if processing but wouldn't be more when I'm processing and not heard in this manner.

As soon as my monitor goes to sleep fan (s) ramp up and down and as soon my monitor is awaken fan (s) are quiet again.
I run powercfg /REQUESTS and I got: [SERVICE] \Device\HarddiskVolume7\Windows\System32\svchost.exe (Schedule)
Windows will execute '\StarVPNService' scheduled task that requested waking the computer.
Windows will execute '\StarVPNService' scheduled task that requested waking the computer.
So I run powercfg /REQUESTSOVERRIDE process StarVPNService Would this be right to stop the service/App? I found this on Reddit: https://www.reddit.com/r/Windows11/comments/1klaffk/finally_solvedfixed_high_fan_speed_and_cpu_usage...
I also found the following which causes fans to Ramp up as soon as monitor goes to sleep. I have disabled Phone link but fans still ramping up.
Would appreciate help in resolving this.

Like I said ... background services are doing their thing.
If the fans don't run, the computer is going to overheat.
Maybe uninstall your Star-VPN and see if the fans get more to your liking.

I will keep on troubleshoot this as this isn't normal for fans to ramp up and down constantly as soon as monitor goes to sleep.

Our EBT2250 does not have this problem. I ran POWERCFG/ REQUESTS and got this:
"margin: 0; ;margin: 0;">SYSTEM:
None.
AWAYMODE:
None.
EXECUTION:
None.
PERFBOOST:
None.
ACTIVELOCKSCREEN:
None.
I did NOT get a SERVICE one? Could that be a clue?
Also if you run powercfg /SYSTEMPOWERREPORT you can get a long HTML file with reams of data, most of which you need to expand to see that could provide more info? Although I can see any direct info to fans in it?
I have not checked the BIOS settings, but they was never changed are at the default setting.
BIOS Version/Date Dell Inc. 1.15.0, 3/9/2026 is installed.
