It seems there is free software fan control (for GPU), but it seems it
depends on the owned hardware.
See here https://askubuntu.com/questions/22108/how-to-control-fan-speed
It should be mostly about the motherboard, and the GPU fan.
but what to look for? Is knowing that nouveau supports the GPU enough (what
about the mobo)?
This (https://nouveau.freedesktop.org/wiki/PowerManagement/) seems to
indicate that Power Management is still a work in progress for some GPU.
I know about a case having PWN. Can this be controlled by free software?
Else there's something like this, which supposedly only rely on hardware (and
me checking the temp).

Lembas, thanks to your advice, I'm picking the power supply last. It seems in
needs to be powered not only to the mobo, but to the GPU as well. Thanks to
h-node, and the nouveau website, I found (way) better and cheaper.
There should be two case fans, the GPU fan(s), the power supply's fan (not
sure I should mess with this one, and the CPU's ones.
