Why does my laptop get so hot? That is a question that the majority of people with laptops will have. This is because this is almost an unavoidable situation that all laptops run into without regular maintenance. So why does your laptop get so hot?
After so long, dust will begin to build up on the cooling components that are designed to keep laptops running at a decent temperature. If the airflow that they need is blocked by the dust then the efficiency of the cooling components can be reduced by more than half. It can reach a critical point that can cause more heat than the laptop can get rid of. Most people would think that too much dust wouldn’t get stuck, but the laptop heatsink is slightly magnetic so it will actually attract some dust that can cause a domino effect. In time, a blanket of dust can form that almost completely blocks the airflow. Since it will act like a cloth, there will be some airflow that you can feel coming through the laptop vents. However, the dust can’t dissipate heat like the heatsink can. Therefore, the dust will become very hot which will cause a buildup of heat inside of your laptop.
The only real way to stay away from this problem is to clean your laptop cooling components regularly. The compressed air can isn’t going to do the job. The “compressed air can” may break up the blanket of dust that has formed, but the dust will still be in there. In some cases, the new blanket that forms can be thicker than the one before it. You will have to open up your laptop to get the dust out completely. This will allow your laptop heatsink to have adequate airflow.
After cleaning your laptop heatsink, you will notice that your computer will be so much cooler than it was before. This will greatly extend the life of your laptop and prevent damage to other components connected to your laptop. You will also be able to answer that dreadful question, “Why does my laptop get so hot?”
