There are parts of your computer that work to prevent extreme temperatures.
One of them is HDD Thermometer. Thanks to it, you can see the temperature of the hard drive. The number in the system tray indicates the current temperature of it.
When the temperate gets too high(default 60 ° C), you can run external applications, shutdown the computer, and send it to hibernate, etc.
HDD Thermometer functions on every part in your computer that has its own thermoter. It warns you about trouble by sounding an alarm when the temperature is too high.
