I was just reminded of how useful this was for me, since i was too lazy to setup fan curves in the cli with pwmconfig. This took me 10 minutes of tinkering and my temps went down a lot under load on my gpu and the machine is a lot more silent when idling.
What happens when the daemon is stopped depends on the implementation of your drivers. I have driver for my mainboard fans that is not in the mainline linux kernel but maintained by a single guy that just recently added the functionality to give back the control to the motherboard (bios settings).
Long story short: if you disable coolercontrol and notice that your fans don’t change their speed when the temperature rises / falls, or act like they did from the bios settings, reboot your system.
In my case it does.
