Power off video card until reboot from command line?
I have "headless" machine with video card, I use very rarely, only if I want physical access to it. The cooler of this video card became old and started to produce bad noise.
Can I disable this video card in such a way, that it:
1) will turn on again on reboot
2) a cooler stop to rotate
I did
lspci | grep VGA
sudo lspci -vs 01:00
to know it's module then I put
blacklist radeon
into
/etc/modprobe/blacklist.conf
but this didn't help.
How to accomplish?

First, look for Bus ID of the graphic card. A possible method is lspci | grep VGA. An output example is:
XX:XX.X VGA compatible controller: NVIDIA Corporation Device 1b80 (rev a1)
Now, you can disable temporally this GPU assigning the value 1 in a file called “remove” inside the correct path of this PCI device. Changing XX with previous Bus ID values.
sudo echo 1 > /sys/bus/pci/devices/0000:XX:XX.X/remove
This command will disable the GPU in runtime. A restart will put the GPU available again. I tested it with a Nvidia GPU in a CentOS 7 server. Maybe the path is different for other GPUs or GNU/Linux distributions. I hope this configuration disables the cooler too.
