What?

gigfun - Utility that takes control over your nVidia video card coolers to keep it cool and steady.

Why?

My GeForce 3090 Ti can not control its own coolers! So that is a kludge to do it programmatically.

How?

The program works as a daemon. When the GPU temperature rises it runs the coolers faster and vice versa. Daemon must be started with Xorg because in requires "Coolbits" options (see below).

Requirements

Go >= 1.16;
nvidia-settings;
nvidia-utils (утилита nvidia-smi);

Setup

Setup the option "Coolbits" how it is described here:

# /etc/X11/xorg.conf.d/nvidia.conf
Section "Device"
    Identifier "Device0"
    Driver     "nvidia"
    Option     "Coolbits" "4"
EndSection

Copy systemd unit to a local user and enable it:

install -D -m 0644 /usr/share/gigfun/service.example ~/.config/systemd/user/gigfun.service
systemctl --user daemon-reload
systemctl --user enable --now gigfun.service
