Why Do I Need Cooling?
As you’ve most likely experienced with a laptop on your lap, computers produce a lot of heat! This is similar to a car engine getting hotter as it’s put through more work. The higher the revs the more the heat. As a computer gets more stressed, it puts out more heat. Most processors (the engine of the computer) nowadays actually slow themselves down as they get hotter, this is called thermal throttling, and it protects the processor from damaging itself. In emergencies, the computer will turn itself off or restart itself if it detects very high temperatures.
