Get Synology NAS CPU temperature via SSH

• In DSM 7 the CPU temperature is shown as "Thermal status" in "Control Panel > Info".
• Active Insight, and DSM 6, refer to CPU temperature as "System temperature".

Works for Intel, AMD and Marvell CPUs in DSM 7 and DSM 6. Also works for Synology models with more than 1 CPU.

• v2.2.5 and later may work for Realtek, Annapurna, STM, Mindspeed and Freescale CPUs.
• To report any problems create an issue and I'll add support for your CPU.

If you schedule the script in Task Scheduler you should enable logging and set the log_directory in the included syno_cpu_temp.conf

1. Download the latest version Source code (zip) from https://github.com/007revad/Synology_CPU_temperature/releases
2. Save the download zip file to a folder on the Synology.
3. Unzip the zip file.

How to enable SSH and login to DSM via SSH

/volume1/scripts/syno_cpu_temp.sh

Note: Replace /volume1/scripts/ with the path to where the script is located.

1. See How to schedule a script in Synology Task Scheduler
2. Enable log and set log_directory in the included syno_cpu_temp.conf
   • syno_cpu_temp.conf needs to be in the same folder as syno_cpu_temp.sh

To enable logging edit the included syno_cpu_temp.conf

Log=yes
Log_Directory="/volume1/backups/diskstation/logs"

Note: Replace /volume1/backups/diskstation/logs with the path to where you want the log saved.

If the script won't run check the following:

1. If the path to the script contains any spaces you need to enclose the path/scriptname in double quotes:

   "/volume1/my scripts/syno_cpu_temp.sh"

2. Make sure you unpacked the zip or rar file that you downloaded and are trying to run the syno_cpu_temp.sh file.
3. Set the syno_cpu_temp.sh file as executable:

   sudo chmod +x "/volume1/scripts/syno_cpu_temp.sh"
