I couldn't find any other topic about this so here we go:

At first, my laptop fans went full speed every few minutes or so for like 5 seconds every time, that got fixed by a bios update. Now it is silent, always, and that's the problem right now, even if it is almost too hot to touch the fans won't speed up so it doesn't cool enough. I looked everywhere for a manual way to turn the fan speed higher (like MSI has on their laptops) but I couldn't find a way.

My question: Can I fix this somehow, is there a setting I missed, is there anything at all I can do about this?

I am also interested in this... Is there any software to regulate the fan speed on new X1 Extreme (version February 2019)?

Hi Quinten0109! Welcome to our forums community. Is the settings set to high performance? Try enabling the Intelligent Cooling under the Think Vantage app. Observe if the issue persist.

Hi Jwes_Lenovo,

Thanks for your response, I started noticing the issue while it was set on Intelligent cooling so I already tried changing it to Performance mode or Cool & quiet mode but the issue persisted, so I reenabled Intelligent cooling.

Try uninstalling and reinstalling the Lenovo Think Vantage app. Run the update then reinstall all available updates. Check if the issue persist.

This all what you are discussing is valid only for Windows OS right?

Yes it is. Did you install another OS on this machine? If you're running Linux, you're laptop is tested to work fine on Ubuntu 18.04.

Yes. I have ubuntu 18.04 and still looking for some application/software for regulating fan speed.

The problem is that the fans are completely dead if the cpu temp drops under certain degree. (Don't know exactly at which point). And then they turn on again at some certain degree. BUT this is the problem. They spin up to very high rpm and then they are too loud because of the speed at which they are spinning.

IMHO when I could get fans to spin always at minimum. (Never turn off) the fans would never have to speed up at some high rpm because the cpu temp wouldn't reach those very high temperatures.
