This post will guide you how to check CPU and HDD or SSD disk temperatures using a command from the command line under openSUSE Linux operating system. How do I use sensors tool to monitor and display the CPU temperature in your OpenSUSE Linux system. How do I use hddtemp tool to check hard disk temperature in Linux.

- Hddtemp Command
- Checking CPU Temperature using Sensors Command
- Checking Hard Disk Temperature using Hddtemp command
Sensors Command
Sensors command can be used to show the current readings of all sensor chips. or set all limits as specified in the configuration file.
The syntax of Sensors command are as follows:
sensors [ options ] [ chips ] sensors -s [ chips ] sensors --bus-list
Options:
-f, --fahrenheit: Print the temperatures in degrees Fahrenheit instead of Celsius.
Hddtemp Command
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.
The syntax of the hddtemp command is as follows:
hddtemp [options] [type:]disk...
Checking CPU Temperature using Sensors Command
To check CPU temperature using sensors command from the command line in your OpenSUSE system, and you need to install it firstly. You can serch sensors package if it is available in the default repository of your openSUSE system with the following zypper search command, type:
$ sudo zypper search sensors
Outputs:
linux-hxqn:~ # zypper search sensors Loading repository data... Reading installed packages... S | Name | Summary | Type --+----------------------------------------+-------------------------------------------------------------+----------- | ftsteutates-sensors | Sensors config ftsteutates | package | libQt5Sensors5 | Qt 5 Sensors library | package | libQt5Sensors5-32bit | Qt 5 Sensors library | package | libQt5Sensors5-imports | QML imports for the Qt 5 Sensors library | package | libmate-sensors-applet-plugin0 | MATE Desktop sensors applet shared libraries | package | libmate-sensors-applet-plugin0-32bit | MATE Desktop sensors applet shared libraries | package | libqt5-qtsensors-devel | Development files for the Qt 5 Sensors library | package | libqt5-qtsensors-devel-32bit | Development files for the Qt 5 Sensors library | package | libqt5-qtsensors-examples | Qt5 sensors examples | package | libqt5-qtsensors-private-headers-devel | Non-ABI stable experimental API for the Qt5 Sensors library | package i | libsensors4 | Hardware health monitoring library | package | libsensors4-32bit | Hardware health monitoring library | package | libsensors4-devel | Hardware health monitoring library | package | mate-applet-sensors | MATE Desktop panel applet to display sensor readings | package | mate-applet-sensors-devel | Development files for mate-sensors-applet | package | mate-applet-sensors-lang | Translations for package mate-sensors-applet | package | monitoring-plugins-sensors | Check hardware status using lm_sensors | package | pcp-pmda-lmsensors | Performance Co-Pilot (PCP) metrics for hardware sensors | package | sensors | Hardware health monitoring for Linux | package | sensors | Hardware health monitoring for Linux | srcpackage | xfce4-panel-plugin-sensors | Hardware Sensor Plugin for the Xfce Panel | package | xfce4-panel-plugin-sensors-devel | Development Files for xfce4-panel-plugin-sensors | package | xfce4-panel-plugin-sensors-lang | Translations for package xfce4-panel-plugin-sensors | package
From the above outputs, you would see that sensors package is available. You can now install it by the following zypper install command, type:
$ sudo zypper install sensors
Outputs:

Then you need to detect hardware monitoring chips installed on your OpenSUSE system with the following command:
$ sudo sensors-detect
Outputs:
linux-hxqn:~ # sensors-detect
# sensors-detect revision 3.4.0-8 (2016-06-01)
# System: innotek GmbH VirtualBox [1.2]

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
Silicon Integrated Systems SIS5595... No
VIA VT82C686 Integrated Sensors... No
VIA VT8231 Integrated Sensors... No

Intel 5500/5520/X58 thermal sensor... No
VIA C7 thermal sensor... No
VIA Nano thermal sensor... No
Some Super I/O chips contain embedded sensors. We have to write to
standard I/O ports to probe them. This is usually safe.
Do you want to scan for Super I/O sensors? (YES/no): Yes
Probing for Super-I/O at 0x2e/0x2f
Trying family `National Semiconductor/ITE'... No
Trying family `SMSC'... No
Trying family `VIA/Winbond/Nuvoton/Fintek'... No
Trying family `ITE'... No
Probing for Super-I/O at 0x4e/0x4f
Trying family `National Semiconductor/ITE'... No
Trying family `SMSC'... Yes
Found unknown chip with ID 0x0b00
Some systems (mainly servers) implement IPMI, a set of common interfaces
through which system health data may be retrieved, amongst other things.
We first try to get the information from SMBIOS. If we don't find it
there, we have to read from arbitrary I/O ports to probe for such
interfaces. This is normally safe. Do you want to scan for IPMI
interfaces? (YES/no): yes
Found `IPMI BMC KCS' at 0xca2... Success!
(confidence 8, driver `to-be-written')
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
Probing for `National Semiconductor LM78' at 0x290... No
Probing for `National Semiconductor LM79' at 0x290... No
Probing for `Winbond W83781D' at 0x290... No
Probing for `Winbond W83782D' at 0x290... No
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

Now follows a summary of the probes I have just done.
Just press ENTER to continue:
Driver `to-be-written':
* ISA bus, address 0xca2
Chip `IPMI BMC KCS' (confidence: 8)
Driver `coretemp':
* Chip `Intel digital thermal sensor' (confidence: 9)
Note: there is no driver for IPMI BMC KCS yet.
Check https://hwmon.wiki.kernel.org/device_support_status for updates.
Do you want to overwrite /etc/sysconfig/lm_sensors? (YES/no): yes
Unloading i2c-dev... OK
Note: 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(3), or more generally by the lm_sensors tool suite.
Now you can run the following sensors command in your system to display CPU temperature information, type:
$ sensors
Outputs:
