Precision 7820 BIOS update fans run fast
I have a DELL Pecision 7820 that since I updated the BIOS the fans run loud.
Is there going to be a UPDATE to the BIOS soon because this is annoying when it ran real quiet before the update.

I have a same problem. The fans run faster when I upgrade the BIOS from Version 1.7.1 to 1.8.2. I use the system diagnosis tools to check the fans speed. Please see the following two figures: the first one is for 1.7.1 and the second one is 1.8.2. Almost all the fans run about 3-4 times faster. This is the reason why the 7820 with new BIOS makes annoying noise.

I have the same problem. Updated the firmware yesterday and since the fans are clearly audible on normal operation while the system was nice and quiet before.
Changing the settings in the BIOS only serves to make the fans even louder, nothing makes them quiet again.

I have now downgraded to 1.3.3, and finally the workstation is quiet again. The reason I picked that specific version is that the next one (1.4.1) is the only one that mentions something about fans in its release notes ("Enhanced the FAN detection and failure reporting mechanism.").
Of course this means that I am now 3 "Urgent" and 2 "Recommended" BIOS updates behind. Thanks, Dell.

I am guessing they are going to leave those speeds?
I liked silent running when not pushing the system.

Hi folks,
I'm considering purchasing a DELL 5820 or 7820 workstation. Just curious if the latest BIOS update v1.9.2 for 7820/7920 solves the noise problem? Thanks!

Definitely not - you need to stay on 1.7.1 to resolve the issue.
I had to downgrade from 1.9.2 to enjoy the previous silent mode.

Have you guys put in service chats/calls about this? I would. They can sometimes forward these concerns on to the engineers. Hopefully. Also, since you are in this boat, would you rather have stability and security with the latest updates or quieter fans with the previous BIOS versions?

Well the downgrade fails going from 1.10.3 back to 1.7.1 on the ME Firmware part just thought I would give a head up to everyone.

Wow, I can't believe this still isn't fixed. I rolled back and won't be updating until this is fixed. Thank you all who reported this is going on.
Dell, are you listening? Can you please address this?

Suggestion: Download HWiNFO (HardWare info). I haven't heard any complaints about it.
One OP (original poster) had her fans get loud. She went through almost all the possibilities - Replaced CMOS battery; replaced thermal paste; computer, vents, and fans were clean; etc. Other tips and videos weren't working. When she downloaded HWiNFO, fans were quiet again. As far as I know, it doesn't just keep them at a fixed speed.

I found that when i removed all disks from flexbay, the fans ran quiet.
