since I upgraded to 21.04, I realized the CPU fan is working with more sound and speed, even when I'm in online classes or watching a YouTube video or just I'm in Firefox.

I didn't have this problem with the earlier versions, even when temperature of the exhaust air was so high.

This mostly occur when I turn the laptop on or put in the charger but eventually there were times when it happened in normal situations.

in the first line of top command output there is whoopsie-upload with usually CPU usage in 50-100 percent. output of top command

output of sensors command

today I get an update for linux-firmware and after update it seems the fan speed losses some speed but the temperature has risen.

Edit :

logs of journalctl -S "2021-06-14 00:00:0" | grep whoopsie is more than 18000 lines full output, few lines of output:

  • @ChanganAuto there is nothing, as I can see. – Mohammad javad Jun 14 '21 at 22:13

  • If you see that whoopsie-upload very often, some process is crashing frequently on your machine. Finding out which one that is and why that happens should be your first priority. Check the journal. – HuHa Jun 14 '21 at 22:17
  • @HuHa how I can check it? – Mohammad javad Jun 14 '21 at 22:19

  • @HuHa did you mean that disable the error reports ? – Mohammad javad Jun 14 '21 at 22:28
  • No, I wrote find out what crashes and why. Suppressing the error message is not going to get you anywhere. – HuHa Jun 15 '21 at 07:00
  • @HuHa I stopped the whoopsie-service and removed everything in /var/crash/ , restart it and now whoopsie is not in top output.(help from another forum), but I still hear the fan sound. – Mohammad javad Jun 15 '21 at 07:27
  • Stopping whoopsie-service just disabled the error reporting. I keep telling you: You should find out what keeps crashing and why. – HuHa Jun 15 '21 at 08:18
  • I'm not good in English, and can't understand the post you send :/ , I checked journal and wrote few lines of output for whoopsie-service, I restarted the service and now it's not in output of top but the fan still works fast. someone in another forum told me do that ! – Mohammad javad Jun 15 '21 at 10:13
