CPU fan runs continuously

I have a Lenevo Ideapad 720S-13IKB (Type 81BV) with Ubuntu 20.04 in it. Note: Support page.

Even when my computer is at idle and using less than 5% of processing power and less than 1GB ram my computers fan makes loud noise and it runs every time .

My idle CPU temperature resides in the range of 40C to 45C which is medium hot. The weird thing is that the fan runs at really at high speed even when RAM being used is less than 1 Gb and processing power being used is less than 5% and it is really annoying.

Hope i can get some help with this.

Initially my fans were running a lot too. But installing tlp worked really well for me. Fans rarely spin now and the system stays cool. Just follow: sudo apt install tlp for Ubuntu. For other distributions and OS, follow Official TLP documentation

Just FYI, my system is a Dell Inspiron 15 7572 (running Ubuntu 20.04)

@CapTen101 I thought so because I am having the same problem on desktop PC. In Windows the fans are quiet, but in Ubuntu they constantly run on higher speeds for some reason. And there are no high loads in my case. So I thought that rather a bug / misconfiguration in fan speed rather than fans responding to high CPU load.
