Why is my laptop overheating even during basic tasks?

Many laptop users encounter overheating issues even when performing basic tasks like browsing the web, checking emails, or running lightweight applications. While it may seem unusual for a laptop to heat up under minimal usage, there are several factors that can contribute to this problem. One of the most common causes is dust buildup in the cooling system . Over time, dust accumulates in fans and air vents, restricting airflow and preventing the laptop from dissipating heat efficiently. Without proper airflow, internal components such as the CPU and GPU can quickly reach high temperatures, causing the system to throttle performance or even shut down unexpectedly to prevent damage. Another factor is aging or dried thermal paste . Thermal paste facilitates heat transfer between the processor and the cooling system. If the paste dries out or becomes less effective over time, heat will not be conducted properly, leading to higher temperatures during operation. In such cases, reapplying hi...
