There
is an excellent little utility to monitor hard drive temperature. Most
modern computer hard disk including SSD comes with S.M.A.R.T
(Self-Monitoring, Analysis, and Reporting Technology). It is a
monitoring system for computer hard disks to detect and report on
various indicators of reliability, in the hope of anticipating failures.
The hddtemp or smartctl utility will give you the temperature of your hard drive by reading data from S.M.A.R.T. 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 a simple command line tool or as a daemon to get information from all servers.
Sample outputs:
Type the following pacman command to install hddtemp under an Arch Linux distro:
Type the following dnf command to install hddtemp under a Fedora Linux distro:
Type the following zypper command to install hddtemp under an OpenSUSE Linux distro :
Untar and install hddtemp using the following commands:
Install hard disk temperature database at /usr/share/misc or /etc directory:
TYPE could be SATA, PATA or SCSI. If omitted hddtemp will try to guess
Sample outputs
Use telnet or nc / netcat command to to get a temperature from a remote box:
OR
Sample outputs:
Sample outputs:
Sample shell script to shutdown box if temperature >= 55°C (download link):
You can run script using a cron job on Linux or Unix-like system:
Append the following to run cron job every 10 minutes to check for disk temp:
Sample outputs:
Set ALERT_LEVEL as per your requirements. Please refer to your hard disk manual for working temperature guideline. Here is general temperature guideline (extracted from Seagate SV35.2 Series Hard Drives Web Page):

$ sudo pacman -S hddtempType the following dnf command to install hddtemp under a Fedora Linux distro:
$ sudo dnf install hddtempType the following zypper command to install hddtemp under an OpenSUSE Linux distro :
$ sudo zypper install hddtempA note about source code installation
You can also perform source code installation. Download the source code tar ball here.$ wget http://download.savannah.nongnu.org/releases/hddtemp/hddtemp-0.3-beta15.tar.bz2Untar and install hddtemp using the following commands:
$ tar -jxvf hddtemp-0.3-beta15.tar.bz2
$ cd hddtemp-0.3-beta15
$ ./configure
$ make
$ sudo make install
Install hard disk temperature database at /usr/share/misc or /etc directory:
$ cd /usr/share/misc
# wget http://download.savannah.nongnu.org/releases/hddtemp/hddtemp.db
Monitor Hard Disks Temperature With hddtemp
Let us see usage, syntax and examples of hddtemp command. The syntax ishddtemp disk

How do I monitor hard disk temperature on Linux?
To see temperature for the /dev/sda, enter the following command:$ hddtemp /dev/sdaSample outputs
/dev/sda: WDC WD2500YS-01SHB1: 25°CAbove output indicate that my hard disk temperature is 25°C. If temperature is higher than 60°C , consider cooling options immediately.
How Do I Find Out Remote Server HDD Temperature?
By default hddtemp bind to TCP/IP port 7634. You need to run hddtemp in daemon mode. Login on remote box and start it as follows to monitor /dev/sda, /dev/sdb, /dev/sdc, and /dev/sdd:# hddtemp -d /dev/sd[abcd]Use telnet or nc / netcat command to to get a temperature from a remote box:
$ telnet remotebox 7634OR
$ nc 192.168.1.100 7634Sample outputs:
|/dev/sda|Samsung SSD 850 EVO mSATA 500GB|45|C|You can format it as follows using the awk command:
nc centos7-box 7634 | awk -F'|' '{print $2 " " $4 $5 "(" $3 ")"}'Sample outputs:
/dev/sda 45C(Samsung SSD 850 EVO mSATA 500GB)
Shutdown Linux Computer If Temperature >= 55
To power off / shutdown computer, run following command via cron tab (cron job) file:t=$(hddtemp /dev/sda --numeric)
[ $t -ge 55 ] && /sbin/shutdown -h 0Sample shell script to shutdown box if temperature >= 55°C (download link):
#!/bin/bash # Purpose: Shutdown server if disk temp crossed $ALERT_LEVEL # Author: Vivek Gite {https://www.cyberciti.biz/}, under GPL v.2.x # ----------------------------------------------------------------- HDDS="/dev/sda /dev/sdb /dev/sdc /dev/sdc /dev/sdd /dev/sde" HDT=/usr/sbin/hddtemp LOG=/usr/bin/logger DOWN=/sbin/shutdown ALERT_LEVEL=60 for disk in $HDDS do if [ -b $disk ]; then HDTEMP=$( ${HDT} --numeric ${disk} ) if [ $HDTEMP -ge $ALERT_LEVEL ]; then $LOG "System going down as hard disk \"$disk\" temperature ($HDTEMP) crossed its limit." sync;sync $DOWN -h 0 fi fi done |
$ sudo crontab -eAppend the following to run cron job every 10 minutes to check for disk temp:
*/10 * * * * /root/bin/chk-disk-temp.bashhddtemp command options
To see usage, run:$ hddtemp --helpSample outputs:
-b --drivebase : display database file content that allow hddtemp to
recognize supported drives.
-D --debug : display various S.M.A.R.T. fields and their values.
Useful to find a value that seems to match the
temperature and/or to send me a report.
(done for every drive supplied).
-d --daemon : run hddtemp in TCP/IP daemon mode (port 7634 by default.)
-f --file=FILE : specify database file to use.
-F --foreground : don't daemonize, stay in foreground.
-l --listen=addr : listen on a specific interface (in TCP/IP daemon mode).
-n --numeric : print only the temperature.
-p --port=# : port to listen to (in TCP/IP daemon mode).
-s --separator=C : separator to use between fields (in TCP/IP daemon mode).
-S --syslog=s : log temperature to syslog every s seconds.
-u --unit=[C|F] : force output temperature either in Celsius or Fahrenheit.
-q --quiet : do not check if the drive is supported.
-v --version : display hddtemp version number.
-w --wake-up : wake-up the drive if need.
-4 : listen on IPv4 sockets only.
-6 : listen on IPv6 sockets only.

Say hello to smartctl Utility
If you have smartctl utility installed, try it as follows to get temperature data:# smartctl -d ata -A /dev/sda | grep -i temperature
smartctl -A /dev/sdb | grep -i temperature
Set ALERT_LEVEL as per your requirements. Please refer to your hard disk manual for working temperature guideline. Here is general temperature guideline (extracted from Seagate SV35.2 Series Hard Drives Web Page):
| Operating | 0 to 60 degrees C |
| Nonoperating | -40 to 70 degrees C |
| Maximum operating temperature change | 20 degrees C per hour |
| Maximum nonoperating temperature change | 30 degrees C per hour |
| Maximum operating case temperature | 69 degrees C |
