Optiplex 3080 fan noise after bios update to 2.1.1

I just updated mine to 2.2.1 but unfortunately no change on the fan noise, still loud as previously reported. 

Same thing here. Bios 2.2.1 is installed but fan is still noisy.

We need a video to hear the fan while booted into the BIOS. We can then forward the link to the Optiplex team.

The fan spins too fast.

It's as easy as that.

Please look at this =

BIOS Causes the Fan to Overspin on the OptiPlex 3080, 5080, and 7080, and Precision 3440 Small Form Factor

did not solve mine...

Sadly it seems like this problem is still not resolved, months after first reported. 

3080 MFF, updated BIOS to very latest, fans now running at 1800RPM

Really disappointing that Dell have not fixed this... these are not cheap computers.

Oh no! If only I had discovered this thread before.

I have now exactly the same problem!

Gave my dad a brand new DELL 3080 Micro. I ordered it brand new and the first thing I did was install a new SSD and then installed Windows 11 fresh. Everything was great! I was really happy with the purchase because even during the installation of Windows 11, the PC was not particularly noisy.

Then after everything was done, the PC automatically pulled probably a firmware update and at the next restart (the last before I gift wrapped the device) it was installed by itself....

Well....and now we have - after the birthday - the device connected  and I'm shocked how unbearably LOUD the PC is without doing anything at all with it!

Even if the PC is just in Windows 11 - nothing is done, no programm opened, the fan runs very audible!

It makes no difference whether I then start intensive programs such as InDesign, Word, etc.. Idle = Loud / Programs = Loud.

Super annoying.

What can be done? There seems to be no new firmware from Dell yet and also no workaround? ;-(

Is it not possible to somehow turn down the fan via external software? I have already tried "SpeedFan", but it does not detect any fan and nothing changes

Diagnostic - my PC also seems to run at a very high RPM for Idle....

Fan Noise 3080 - Looud :-(

Hi

Got a brand new Optiplex 3080 micro and got exactly the same issue after 2.2.1 bios udpdate.

Just got in diagnostics these result for cpu fan :

Current : 1826

Low : 1602

High : 1828

So I got the exact same problem.

Fan run constantly at around 1800rpm.

For a daily use it is really annoying.

I got the exact same noise in idle mode as  @Fischwaage

His video represent my case.

Any firmware update will be released to solve that ?

Thanks

Hi Chris,

I just purchased a new OptiPlex 3080 MFF and I am suffering from the same annoying problem - after upgrading to Win11, Dell command center automatically updated the bios version to the latest (2.2.1.) and from than the fan is spinning on full power all the time - even when the PC is idle - the fan is always rotating on full speed causing a very loud noise!

 Here is a video proving the loud noise-

please release an update to the BIOS solving this annoying issue as soon as possible.

Eyal

You can clearly see that after a fresh boot, there is not any heavy app that is currently running, but the fan is still spinning very fast causing a "bzzzzzzzzzzz" sound-

Hello,

Same problem with a 3080 micro present after unpacking yesterday and still present after 2.2.1 bios upgrade. CPU Fan is ~1800rpm.
