freon

Freon is a fork of gnome-shell-extension-sensors,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. For the GPU temperature, you may need to install the vendor's driver for best results.

This extension supports GNOME Shell 3.12+ (To check other versions, modify "shell-version" in "metadata.json")

NOTE: Freon relies on lm_sensors. You must run sensors-detect before Freon will be able to detect and display hardware temperatures. To see GPU temperatures, you will also need the driver and related packages from your GPU's vendor -- see the list of dependencies.
