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 pulled the NVMe drive. And the computer is quiet. Will see if it stays quiet all day.
I understand Alan says that the November Bios should fix it, but considering the start of this thread was October of last year, I'm not 100% confident that it'll be remedied. Dell support was clueless when my first machine's motherboard & SSD fried.
You'd think if a fix was in the works, they would have been aware of it when replacing parts and ultimately my whole machine.
Sad that I was shoehorned into getting this Dell workstation because of a corporate contract.

As a costumer with the same problem: I can assure, the November BIOS will fix the loud fan/NVMe-problem for the Precision 7820/7920 Tower.

Another customer with a brand new Precision 7820 tower with same problem, chiming in. I've bookmarked the page and will be waiting for the update.

The noise mainly come from two rear fans. Therefore, if we can reduce the rear fans speed, the workstation will not make loudly noise.
I found that the linux tools i8kutils could help us to control fan speed. So I program a fan tool which can not only read all fans speed but also make two rear fans at low speed. It works on my dell 7820 workstation with Redhat 8.0 system. Please note that all fans will be reset after power off.

I think the LATEST BIOS update made the fans run quiet again.
I just wish it didn't take so long to get this update.
But thanks DELL I have been waiting awhile for this.

Wow, this took a long long time to fix it officially.
I can confirm, that the latest BIOS-Update 2.4.1. solves the describes problem for me.
I hope I will be recovered from my BIOS-update-phobia someday

I don’t know, folks, my fans still randomly go to loud speeds after updating to 2.4.1. Perhaps it’s better but I wouldn’t call the issue “fixed” on my end.
Alan, do you know if the 2.4.1 update was supposed to address the loud fans issue?

@jasond916 going by your statement I don't think you have the same issue that the BIOS revision was designed to resolve. It was designed to address fan noise at idle amongst other points outlined in the release notes.
As others have stated, it has resolved that issue for them.
Your system fan sounds like its operating normally but it also could be your perception of the issue.
My suggestion would be to run HWINFO64 and note down what the fan speeds are when the system is "going to loud speeds"

Copy that. Thanks for the reply, Alan! I’ll look into that.

This was never fixed? I have a Precision 7820 built in 2021 and it does this same thing. I have the latest BIOS, but every time I put an NVME drive in there it sounds like a leaf blower.

@TRGemm
I've a 7820 built prior to 2020 (june 2018 to be precise), and I've never experienced sound issues linked to the fans ( I use a nvme in the flexbay ) except for a bearing issue that resulted in changing one fan under warranty. For personal reasons (I don't need the subsequent changes/fixes) I'm at bios 2.6.3 .
It's always VERY quiet
To be precise, I have 1 x nvme in the front flexbay , and 3 x sata hdd installed internally, with 1 x flexbay empty for a 2nd nvme/u.2 unit

Hey there, is anyone still having this issue on the latest bios? I'm using a PCI NVME so removed the contents of the flexbay + set the thermal options to quiet in the BIOS but the machine still seems to run unnecessarily loud. Interestingly I have a Precision 7810 that does not have this issue at all.
My HWInfo screenshot is not displaying here but the max temp on sensors 0-7 is 38c but fans are all running at 1500rpm. CPU/GPU temps are fine and thermal paste has been replaced.
