My laptop fan runs continuously even when not using the application. CPU fan speed is 2300 RPM. Is that normal? This is my first time using elementary OS.

Use the top command in Terminal and check the %CPU column.

  • Good suggestion. I sometimes have one or more -bash commands eating up resources. After killing them, CPU usage (and thus fan speeds) return to normal. – Magnus Teekivi Dec 10 '17 at 9:42
  • Thanks for answering my question. My CPU is about 40%. When I use windows fans will turn slower when the machine is not working. But in the elementary os, it always rotates at a high speed. Does windows have BIOS, elementary not? – Soju Dec 11 '17 at 12:18
  • I think it's some software you installed that keeps running in the backgraound after you close it. That's why I suggested the top command to see which app is consuming CPU. – cristian mos Dec 11 '17 at 17:27

The top command is what was needed. THX alot. Ad first I tried to find out with gnome system monitor..it showed me 0% CPU usage. top command

identified high CPU usage of packgagekitd

, which is an update lookup and for the reason my fans where spinning full time. Just in case you experience the same issue..after using top, type:

sudo killall -KILL packagekitd

and quite time is back again.BTW, I'm new to Elementary Os..I started with Juno..
