Configure RealTemp to Shutdown Windows After CPU Reaches High Temperature

In the summer time, if you are hiding in your air-conditioned house or office then everything is fine. But the moment you walk out and start using your notebook computer, the CPU starts to heat up and the temperatures may go very high. Even though all modern processors are designed with high temperature protection and the CPU cooling fan keeps the CPU properly cooled down, operating your computer at high temperatures can bring down its overall life.

If you do not want your CPU to go above a temperature range, then you can use RealTemp to automatically shutdown your PC in any such event. The program does not support shutting down PC directly, but it does support launching an alert program when your CPU crosses a certain temperature. We can use this feature to auto-shutdown your PC when high temperatures are reached. Here is how:

  1. Download from and extract it to any folder of your choice. You will see two files launcher.exe and launcher.bat. When launcher.exe is run, it simply executes launcher.bat. So you can enter your shutdown command in launcher.bat. The default command is shutdown /s /t 100 which shutdowns your Windows PC after 100 seconds, but you can modify it to your liking.
  2. Download RealTemp from and extract it to a folder.
  3. In the main window of RealTemp, click on the Settings button.Shutdown PC After High CPU Temp
  4. Select the checkbox Alarm temperatures and change the temperature when RealTemp should execute the Alarm executable. For a typical CPU, 80°C is a good temperature. If you have selected the Fahrenheit temperature unit, then use temperature value in that unit.
  5. Click on the Alarm EXE button and choose launcher.exe from step 1 above.Shutdown PC After High CPU Temp
  6. Click on the OK button and you are all set.

If you do not want to use as mentioned in these instructions, you can create your own BATCH script and convert it into an EXE file using one of the BATCH to EXE tools available on the internet.
