Linux find NVMe SSD temperature command

The procedure to show NVMe SSD temperature on Linux is as follows:

1. Open the terminal application
2. Install nvme-cli tool on Linux using your package manager
3. Run sudo nvme smart-log /dev/nvme0 Linux command to display temperature information for NVMe SSD

Let us see how to install nvme-cli and display temperature using the command line options.

How to install nvme-cli on Linux

Run the following command as per your Linux distro.

Ubuntu/Debian Linux

Type apt command or apt-get command:
sudo apt install nvme-cli

Fedora Linux

Execute the following dnf command:
sudo dnf install nvme-cli

Arch Linux

Type pacman command:
sudo pacman -S nvme-cli

OpenSUSE or Suse Linux

As usual run the zypper command:
sudo zypper install nvme-cli

Alpine Linux

Use apk command as follows
sudo apk add nvme-cli nvme-cli-doc

How do I display NVMe PCI SSD temperature on Linux

First, login as root user using the su command or sudo command:
sudo -i
OR
su -
Now, check NVMe temp in Linux:
sudo nvme smart-log {Device_Name}
sudo nvme smart-log /dev/nvme0
sudo nvme smart-log /dev/nvme1n1
The ‘{Device_Name}’ may be either an NVMe character device. For example, /dev/nvme0) or an nvme block device such as /dev/nvme0n1. Use the grep command to filter out data:
sudo nvme smart-log /dev/nvme0 | grep '^temperature'
Use bash for loop for multiple devices as follows:

 # /dev/nvme0 and /dev/nvme1
for d in /dev/nvme{0..1}
do 
 echo "$d - $(sudo nvme smart-log $d | grep '^temperature')"
done

Conclusion

You learned the nvme Linux command that we used to find NVMe SSD temperature. This command has many more options. See the man page by typing the following man command or visiting the project page online here:
man nvme
