kojack Posted April 28 Share Posted April 28 I have noticed since I did a bios and full software update my fan is running alot more than normal. Any ideas where to look to see what is causing it? 1 Workstation - Dell XPS 8940 - desktop creative powerhouse Mobile Workstation - Dell inspiron 5406 2 in 1 - mobile creative beast Wifey's Notebook - Dell inspiron 3169 - Little gem for our businesses Link to comment Share on other sites More sharing options...
Aaron44126 Posted April 28 Share Posted April 28 Thoughts... 1. Do a full system shutdown and then turn it on again from a cold boot, if you have not done that yet... That will reset the EC if something about the BIOS update process itself caused it to change fan behavior. 2. Check Task Manager "Details" tab and sort processes by CPU usage. Make sure there isn't a rogue background process gobbling CPU time. (With today's many-core CPUs, even low values in the CPU use % column are concerning. For example, in a system with eight logical cores [4 cores + hyperthreading], 12% CPU use [100% ÷ 8] represents a full core of activity, shouldn't be happening on an idle workload, and would most likely cause the fans to spin up.) 3. It's possible that Dell bungled the fan tables in the latest BIOS update. Wouldn't be the first time. You can roll back to the previous BIOS version and see if it behaves better. 2 Apple MacBook Pro 16-inch, 2023 (personal) • Dell Precision 7560 (work) • Full specs in spoiler block below Info posts (Windows) — Turbo boost toggle • The problem with Windows 11 • About Windows 10 LTSC Spoiler Apple MacBook Pro 16-inch, 2023 (personal) M2 Max 4 efficiency cores 8 performance cores 38-core Apple GPU 96GB LPDDR5-6400 8TB SSD macOS 14 "Sonoma" 16.2" 3456×2234 120 Hz mini-LED ProMotion display Wi-Fi 6E + Bluetooth 5.3 99.6Wh battery 1080p webcam Fingerprint reader Also — iPhone 12 Pro 512GB, Apple Watch Series 8 Dell Precision 7560 (work) Intel Xeon W-11955M ("Tiger Lake") 8×2.6 GHz base, 5.0 GHz turbo, hyperthreading ("Willow Cove") 64GB DDR4-3200 ECC NVIDIA RTX A2000 4GB Storage: 512GB system drive (Micron 2300) 4TB additional storage (Sabrent Rocket Q4) Windows 10 Enterprise LTSC 2021 15.6" 3940×2160 IPS display Intel Wi-Fi AX210 (Wi-Fi 6E + Bluetooth 5.3) 95Wh battery 720p IR webcam Fingerprint reader Previous Dell Precision 7770, 7530, 7510, M4800, M6700 Dell Latitude E6520 Dell Inspiron 1720, 5150 Dell Latitude CPi Link to comment Share on other sites More sharing options...

How can I back track bios updates? I have tried everything else you mentioned. Edit: I just looked in task manager my CPU is being used between 8-24% off and on. Nothing to cause the fans to be hitting hard. I use this system daily and never had fans going unless I was doing a video edit encode etc. 1 Workstation - Dell XPS 8940 - desktop creative powerhouse Mobile Workstation - Dell inspiron 5406 2 in 1 - mobile creative beast Wifey's Notebook - Dell inspiron 3169 - Little gem for our businesses Link to comment Share on other sites More sharing options...

Go to dell.com/support, look up your system model, and go to driver downloads. You should be able to find old BIOS versions in there. Just run the .exe to install. Two gotchas: Occasionally they release a BIOS update and you will see in the release notes that you can't downgrade if you upgrade to this version. It is not always possible to downgrade. Also, in BIOS setup there is an option to block BIOS downgrades, which you might have to disable. 2 Apple MacBook Pro 16-inch, 2023 (personal) • Dell Precision 7560 (work) • Full specs in spoiler block below Info posts (Windows) — Turbo boost toggle • The problem with Windows 11 • About Windows 10 LTSC Spoiler Apple MacBook Pro 16-inch, 2023 (personal) M2 Max 4 efficiency cores 8 performance cores 38-core Apple GPU 96GB LPDDR5-6400 8TB SSD macOS 14 "Sonoma" 16.2" 3456×2234 120 Hz mini-LED ProMotion display Wi-Fi 6E + Bluetooth 5.3 99.6Wh battery 1080p webcam Fingerprint reader Also — iPhone 12 Pro 512GB, Apple Watch Series 8 Dell Precision 7560 (work) Intel Xeon W-11955M ("Tiger Lake") 8×2.6 GHz base, 5.0 GHz turbo, hyperthreading ("Willow Cove") 64GB DDR4-3200 ECC NVIDIA RTX A2000 4GB Storage: 512GB system drive (Micron 2300) 4TB additional storage (Sabrent Rocket Q4) Windows 10 Enterprise LTSC 2021 15.6" 3940×2160 IPS display Intel Wi-Fi AX210 (Wi-Fi 6E + Bluetooth 5.3) 95Wh battery 720p IR webcam Fingerprint reader Previous Dell Precision 7770, 7530, 7510, M4800, M6700 Dell Latitude E6520 Dell Inspiron 1720, 5150 Dell Latitude CPi Link to comment Share on other sites More sharing options...
kojack Posted June 27 Author Share Posted June 27 A new Bios was released this past week. It fixed all the issues, and make the system much faster in the process. I think they gooched the previous one and went to work resolving those issues. All is great again. Got extra battery life while unplugged, get faster system use and quiet! phew!
