If you would like to check hardware health like CPU temperature, hard disk temperature, fan speed, etc,. I would like to advise you to go with lm_sensors & hddtemp.
lm_sensors (Linux monitoring sensors) is a free and open-source application that provides tools and drivers for monitoring temperatures, voltage, and fans.
It’s a CLI utility and if you are looking for alternative tools. I would suggest you to go for s-tui : Stress Terminal UI is a terminal UI for monitoring your computer.
sensors is used to show the current readings of all sensor chips.
sensors -s is used to set all limits as specified in the configuration file.
sensors –bus-list is used to generate bus statements suitable for the configuration file.
sensors-detect is an interactive program that will walk you through the process of scanning your system for various hardware monitoring chips, or sensors, supported by libsensors, or more generally by the lm_sensors tool suite.
sensors-detect will look for the following devices, in order:
- Sensors embedded in Super I/O chips.
- Hardware monitoring chips accessed through ISA I/O ports.
- Hardware monitoring chips reachable over the SMBus or more generally any I2C bus on your system.
hddtemp will give you the temperature of your hard drive by reading Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.) information on drives that support this feature.
Only modern hard drives have a temperature sensor. hddtemp supports reading S.M.A.R.T. information from SCSI drives too.hddtemp can work as simple command line tool or as a daemon.
These tool provides some essential command line utilities for monitoring these devices. Also, it helps you to find out a defective hardware components on your system.
How to install lm_sensor & hddtemp in Linux
There are various ways to install lm_sensor & hddtemp in Linux, depending on which Linux distribution you use.
Pre built packages are available in most of the Linux distribution official repository so, use the appropriate distribution Package Manager to perform the installation.
For Fedora system, use DNF Command to install TLP.
$ sudo dnf install lm-sensors hddtemp
For Debian/Ubuntu systems, use APT-GET Command or APT Command to install TLP.
$ sudo apt install lm-sensors hddtemp
For Arch Linux based systems, use Pacman Command to install TLP.
$ sudo pacman -S lm-sensors hddtemp
For RHEL/CentOS systems, use YUM Command to install TLP.
$ sudo yum install lm-sensors hddtemp
For openSUSE Leap system, use Zypper Command to install TLP.
$ sudo zypper sensors hddtemp
How to configure lm-sensors in Linux
Once you have installed, run the following command to configure lm-sensors in Linux. It will prompt you to confirm many times while you configuring the lm-sensors on your system and simply say YES to all.
sensors-detect will generate the /etc/conf.d/lm_sensors configuration file which is used by lm_sensors.service and defines the kernel modules to be loaded on boot.
$ sudo sensors-detect
# sensors-detect revision $Revision$
# System: LENOVO 80NV [Lenovo ideapad Y700-15ISK] (laptop)
# Board: LENOVO Allsparks 5A
# Kernel: 4.19.6-1-MANJARO x86_64
# Processor: Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz (6/94/3)
This program will help you determine which kernel modules you need
to load to use lm_sensors most effectively. It is generally safe
and recommended to accept the default answers to all questions,
unless you know what you're doing.
Some south bridges, CPUs or memory controllers contain embedded sensors.
Do you want to scan for them? This is totally safe. (YES/no): YES

Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.

Some hardware monitoring chips are accessible through the ISA I/O ports.
We have to write to arbitrary I/O ports to probe them. This is usually
safe though. Yes, you do have ISA I/O ports even if you do not have any
ISA slots! Do you want to scan the ISA I/O ports? (YES/no): YES

Lastly, we can probe the I2C/SMBus adapters for connected hardware
monitoring devices. This is the most risky part, and while it works
reasonably well on most systems, it has been reported to cause trouble
on some systems.
Do you want to probe the I2C/SMBus adapters now? (YES/no): YES

Install Psensor in Linux
psensor is a graphical hardware temperature monitor for Linux. The application is designed to be simple and easy to use. The CPU and memory consumption are not significant.
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 ATI/AMD GPUs (not enabled in official distribution repositories, see the instructions for enabling its support).
- the temperature of the Hard Disk Drives (using hddtemp or libatasmart).
- the rotation speed of the fans (using lm-sensors).
- the CPU usage (since 0.6.2.10 and using Gtop2).
