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.

if one already has set their (primitive) curves in the crappy bios interface, does this just override them once the daemon is running?

In my case it does.

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.
