Fan 0 RPM, hardware or software error?

cn flag

I have a new computer and after approx. two weeks I noticed the unit heating up and the fan no longer on. I have checked and despite the heat, it is always at 0 RPM. I was unable to find any fan options in the BIOS.

Is there an easy way to check if this is a hardware or software fault?

Many thanks!

My system:
Kubuntu 21.04
Lenovo Thinkpad L13 Yoga 2nd Gen

Update 1 (2021-06-16)

@Terrance Thanks for the tip with the Live USB!

I ran the live USB without installing Kubuntu and the laptop was quite hot and I heard no fan. I then installed lm-sensors (still on the live USB) via

sudo apt install lm-sensors 

and checked the fan speed with:

sensors | grep -i fan 

I still get

fan1: 0 RPM

Can I then assume that I have a hardware fault?

If you boot to a Live USB that will eliminate your installed OS as being the issue. The fan should be running all the time the system is turned on.

It was indeed a faulty fan, which has been now replaced.

Strangely

sensors | grep -i fan 

is still showing

fan1: 0 RPM

But fan is running and temperatures much lower.

How did you determine the issue was in hardware?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
