I am getting this annoyance from time to time, on my current machine, a Thinkpad X1 gen4, running a fully updated Manjaro. I had the same problem on my previous machine, a Thinkpad T440, and also having it on my second laptop an old HP ProBook 4520s:
every once in a while, the CPU fan spins up to 100% and remains pegged there, regardless of the load. Htop tells max 4% load, but the fan noise is still there, even after hours of not using the laptop. Not even a restart solves the problem. Only shutdown and start-up again.
It does not appear to be linked to any update, btw.
I would like to avoid having to shutdown the laptop just to get rid of the fan noise. Are there other things that I could do to somehow “reset” the fan speed from the command line? Any pointers to what I should investigate or configure or install are greatly appreciated. Thanks in advance!
provide system info:
Hi @dorin00, and welcome!
Try tlp, available from the
$ pamac search tlp [...] tlp [Installed] 1.5.0-5 community Linux Advanced Power Management
And it has a UI, also in the
community repository, that will install it:
$ pamac search tlp [...] tlpui [Installed] 184.108.40.206-1 community A GTK user interface for TLP written in Python [...]
So, it can b e installed with:
pamac install tlpui
That can possibly help, and I hope it does!
You can find another program to control your fan. I use
nbfc, for example. Here, you can find some other options.
Maybe limit your CPU performance peak on AC and DC ??
Using tlpui → Processor → CPU_Perf , i use 80% with boost.
