Why overheating is bad for your computer

No one likes getting all hot and bothered, and the same goes for your computer! Here’s what can happen and what you can do to avoid it.

When your computer overheats, it can cause damage to its internal components, leading to slower performance, crashes, and even permanent damage.  

  • An overheated processor slows down and works less efficiently. In a computer system that functions properly, the fans should activate when the processor begins to overheat.  
  • Most laptop batteries have lithium-ion batteries that can be harmed by heat. The added heat and increased chemical reaction reduce the battery life and amount of time it stays charged. With prolonged exposure to high heat, the battery may even become unusable.
  • Overheating can also cause your computer to shut down unexpectedly, which can be frustrating if you're in the middle of working on something important (say goodbye to that best-selling book!).

So, what can you do?

Make sure your computer is well-ventilated. This means keeping it in a room with good airflow, and not placing it in a cramped space like a cabinet or under a desk. You can also use a cooling pad or fan to help keep things cool.

Keep your computer clean. Dust and dirt can build up inside your computer and block the fans and air vents, which can lead to overheating. Regularly clean your computer with compressed air or a soft cloth to prevent this from happening.

Avoid using your computer on soft surfaces like beds or couches. These surfaces can block the air vents on the bottom of your laptop, which can cause it to overheat. Instead, use your computer on a hard, flat surface like a desk or table.
