Linux Ubuntu bionic xfce
I managed to find a solution by hunting the Web to control the curve of Nvidia's grabbo (controlling the fan according to the temperature of the grabbo) on Linux.
/path/to/script
#!/bin/bash
#Make sure to enable nvidia-xconfig --cool-bits=4
#This new script works with version 378.13 driver
#Old script is not functional (on Arch, at least)
#Changed up some options and flags for nvidia-settings
#Added some comments for clarity, in case other people want to make improved forks
#enable headless mode
#request lightdm installed - apt install --no-install-recommends xorg lightdm for debian/ubuntu

if [ "$headless" = true ] ; then
export DISPLAY=:0 XAUTHORITY=/var/run/lightdm/root/:0

#Enable user defined fancontrol for all gpu
nvidia-settings -a "GPUFanControlState=1"
while true
do

#Get GPU temperature of all cards
for gputemp in $(nvidia-smi --query-gpu=temperature.gpu --format=csv,noheader);do
if [ "$verbose" = true ] ; then
echo "gpu ${i} temp ${gputemp}";
fi
#Note: you need to set the minimum fan speed to a non-zero value, or it won't work
#This fan profile is being used in my GTX580 (Fermi). Change it as necessary
#If temperature is between X to Y degrees, set fanspeed to Z value
