What Are The Main Causes of A Laptop Overheating?

An estimated 9 out of 10 times your laptop will overheat simply because of a lack of airflow.  Over an extended period of time if a laptop builds up enough dirt and debris in the fan blades, inside the case, in exhaust vents and other places, it will completely limit airflow and prevents the computer from being able to cool itself down.  This can cause extreme problems if left untreated, including hardware failure.

How Does a Laptop Overheat? 

In most circumstances, a build up of outside debris on the heatsink inside your computer, in the fan blades and exhaust vents restricts airflow through the laptop case.  When there is little or no airflow through the laptop case, the components inside of your computer become hot.  Air is not able to flow through the heatsink of the CPU causing the processor to run hot, when the temperature of the CPU becomes hotter than the CPU is able to handle, it can cause severe hardware failure and slowly damage the hardware inside the laptop.  In a clean case, the heat from your laptop computer's components (CPU, graphics card, hard drive, etc) is sent through a series of metal pieces aka the heatsink, this heatsink creates a larger metal surface for the heat to travel to, increasing the surface area available for cool air to blow across, thus cooling down your components.  It operates in a very similar way to the radiator on your vehicle.  When these components are clogged with dust, the heat transferred has no way of being cooled down and continues to heat.

How Do I Know if My Laptop Computer is Overheating?

Every computer is different; however, the symptoms are generally the same with every laptop computer.

Left unchecked, these issues will always multiply and become worse, possibly ruining the hardware inside of your laptop permanently.

How Do I Fix an Overheating Laptop?

There are numerous ways to fix an overheating laptop if the root cause is a lack of airflow.  Take a trip to your local walmart or hardware store and purchase a can of compressed air.  With the straw attached to the can, blow the air into the fans and exhaust vents of the laptop.  This will loosen the dust from your intake and fans and exhaust, and allow air to flow through.  Without disassembling the laptop, this will only be a very temporary fix as the dust will remain inside of your laptop.  Many people would recommend using a shopvac or hose attachment on a vacuum to remove the dust compeltely.  While this can work well, you risk putting strain on the small components inside of your laptop case.  The best way to ensure there is no debris inhibiting airflow is to open the laptop, and blow the dust out completely.
