Psensor is a graphical hardware temperature monitor for Linux.

It can monitor:

  • the temperature of the motherboard and CPU sensors (using lm-sensors).
  • the temperature of the NVidia GPUs (using XNVCtrl).
  • the temperature of the Hard Disk Drives (using hddtemp).
  • the rotation speed of the fans (using lm-sensors)

Installation

First step is to install lm-sensors:

sudo apt-get install lm-sensors

Then, starts the detection of your hardware sensors:

sudo sensors-detect

Verify that it works:

sensors

It should display something like:

coretemp-isa-0000
Adapter: ISA adapter
Core 0: +46.0C (high = +76.0C, crit = +100.0C)

coretemp-isa-0001
Adapter: ISA adapter
Core 1: +44.0C (high = +76.0C, crit = +100.0C)

…

Install psensor from ppa:

sudo apt-add-repository ppa:jfi/ppa
