Cause of Laptop Overheating

Every laptop or desktop equipped with a central processing unit which act as brain as simple as human brain, processor needs to be cool every time as human brain because if your mind is not cool you will make wrong decisions or you feel frustrated. same thing happens with the laptops when processor heats-up it starts freezing, slow processing etc.

To make the processor cool Heat sink and fan placed in the laptop, heat sink absorbs heat and fan makes the heat sink cool by thronging air from it, this is the same technology which used in air conditioners.

In case of air conditioners heating coil absorb heat and fan on the back make it cool by passing cold air from heating coil that’s why air conditioners threw hot air from the back. In case of air conditioner cooling coil needs to be clean every year.

Main cause for laptop overheating is heat sink choking, normally fan sucks air from the bottom and by passing it trough the heat sink threw the hot air from the back. While sucking air from the bottom it sucks dust partials as well which results heat sink chocking and due to cloaking air can’t pass from the heat sink which results heat sink not cooling down which cause laptop overheating.

Second main cause for overheating is faulty fan, if fan is faulty then obviously it can’t make heat sink cool which results laptop overheating.
