gnome-shell-extension-freon

Freon is a GNOME Shell extension for displaying the temperature of your CPU, hard disk, solid state, and video card (NVIDIA, Catalyst, and Bumblebee supported), as well as power supply voltage, and fan speed. You can choose which HDD/SSD or other devices to include, what temperature units to use, and how often to refresh the sensors readout, and they will appear in the GNOME Shell top bar. **NOTE** that if you want to see GPU temperature, you will need to install the vendor's driver and any related packages. (Nouveau unfortunately won't work for Nvidia cards.) * hard drive temperatures requires that you probe the `drivetemp.ko` kernel module. One way is to add the file /etc/modules-load.d/drivetemp.conf with a single line saying drivetemp * Nvidia GPU temperatures require the `nvidia-settings` application, typically installed with the proprietary Nvidia drivers. * Bumblebee + Nvidia requires `optirun`. * AMD GPU temperatures requires `aticonfig`, part of AMD Radeon Software (formerly known as AMD Catalyst).
