What causes laptop overheating?
Overheating in laptops can be attributed to several factors, the most common being dust accumulation, malfunctioning fans, thermal paste degradation, and insufficient ventilation. Dust and dirt can clog air vents, making it difficult for the cooling system to dissipate heat. Fans may not operate efficiently due to mechanical failure or dirt buildup, leading to inadequate cooling. Additionally, over time, thermal paste that ensures good heat transfer between the CPU and heatsink can dry out and lose its effectiveness.
Another contributing factor is excessive usage of demanding applications or running multiple programs simultaneously. Heavy tasks, such as gaming or video editing, generate significant heat. If the laptop’s cooling system isn’t capable of handling the increased load, it can lead to overheating.
