How is managed automatic fancontrol ?

Hi.

I use fancontrol to manage fan speed for CPU and GPU.
I feel that main fan (extractor connected to "fan2" on Motherboard, "fan1" beeing CPU fan) runs mainly too slow. But I don't know how to configure fan speed and which temperature to watch.
Anyway, in most cases, automatic control is fine. Could you explain me how is managed automatic fancontrol ? Is it linux kernel or simply motherboard who controls it ? Is there a way to configure a higher level for fan speed without setting up a correlation between fan speed and a specific temperature ?

Thanks for your help.

At first I would start at the BIOS. If it is not too old, there should be options to control it either depending in the temp or static.

There is https://wiki.gentoo.org/wiki/Fan_speed_control/lm_sensors%27_fancontrol for the software side.
