Fans are running constantly
Hi, I have Dell Pro Max 14 MC14250 with Ubuntu 24.04. I have an issue with fans - they are running constantly. Not fully, I would say on 40-50%.
- I have checked processes, there is not anything greedy (as of now, only 9% maximum by Chrome, and next 1.75% CPU by gnome-shell),
- I have checked sensors, all of them are 50.0°C maximum.
- The battery has full capacity (and besides I am plugged in to the electricity),
- This notebook is relatively new (09/25), always kept indoor, so I do not believe it has dust inside.
- The fans run also when I turn off everything, and put energy mode to Balanced or Power Saver,
- I have tried Live USB Try Ubuntu, the fans were running as well, so I believe it has nothing to do with the operating system directly.
Can somebody advise how to solve this? I can live with this issue but I believe it is not normal and it would shorten the lifespan of the laptop.
Thank you.

Since the fans run constantly even on a Live USB ("Try Ubuntu"), the issue is almost certainly a hardware or BIOS/UEFI-level firmware behavior rather than a software problem within Ubuntu. High-performance models sometimes default to an aggressive fan curve or an "Always On" setting to remain cool.

Hi
I believe the fan control is not fully achievable on that model (Dell Pro Max 14 MC14250),
however the interweb LLM suggests this...........
Short answer: You can usually stop the Pro Max 14’s fans from running full‑speed on Ubuntu 24.04 by
(1) installing Dell-specific utilities (i8kutils or dell-bios-fan-control),
(2) enabling the kernel module that exposes Dell SMM fan controls, and
(3) running a userspace fan manager (i8kmon or a systemd service) to apply temperature-based curves — but exact steps depend on whether the BIOS allows user control on your MC14250 and on whether the fans are exposed via /sys.
