Lenovo Yoga 520 + Linux fan problems

Hi all,

i got a Lenovo Yoga 520 notebook Intel® Core™ i5-7200U CPU @ 2.50GHz × 4 running Linux Fedora 30 OS.

I'm really satisfied about the notebbok but i'm experimenting problems with the fan. When performing cpu intensive (but not so intensive) tasks, the CPU warms up and switch into protection mode (400MhZ). 

I'n mot able to determine if the fan is working but, since i do not ear any rumor i suppose the fan is not working.

May it depends on Linux? is there  eway to check fan status?

 

Best

In Fedora 30 you should be able to run "inxi -F".  In the output toward the bottom it should show temperature of CPUs and fan speed

Re: Lenovo Yoga 520 + Linux fan problems

Hi Dave,

you are right but ir seems that there is not a fan sensor installed on this notebook.

When asking for fan speed the output is always the same (doesnt matter which tool i used):

 

Fan speed (RPM): N/A

 

Is it correct? Should i expect the fan speed?

Hi Max,

 

    It seems you cannot get the fan speed by tools such as inxi, lm_sensors  on some of the IdeaPad products. In this case, I suggest to find the processor with the highest CPU comsumpsion by 'top' command. A better choice for monitoring the CPU temperature and processors at the same time is 'glances', you can installl by:

sudo dnf install glances

or use 'pip3':

pip3 install --user glances
