Causes for computer overheating

What are the main causes for computer overheating?

At times your computer overheats due to various reasons. If the system is kept in a high temperature environment, you might experience overheating in your system. The other possible reasons can be the corruption of the software that controls the fans or due to defective cooling fans in the system. Excessive or continuous use of your computer for long hours can also be a reason for overheating. The consequences of overheating can be error messages being displayed or system damages, some of which can be irreparable. If the air circulation inside the computer is blocked or dust accumulation in the system can also be some of the reasons behind the computer overheating. Overheating can reduce the lifespan and destroy the hardware components within your computer, leading to data loss and irreparable damage. An overheated computer will also exhibit declining performance.

Given below are some of the causes and tips to avoid overheating in computers:

  • Clean your computer

  • Shut down system

  • Cooling devices

Clean your computer

Dust can slow down the fans or other mechanical components inside your computer. Dust particles will also act as an insulator causing heat inside the system to increase. The dust accumulated on the hardware components increases the chance of overheating the computer as it obstructs airflow inside the system. You should regularly clean your computer to remove the dust particles from the system.

Shut down system

After continuous usage, shut down the system and allow it to cool. Make sure that you keep your system turned off when you are not using it. Computer overheating can occur when you use your system in high temperatures for a continuous period of time. It is recommended to use your computer in a cool environment preferably an air conditioned environment.

Cooling devices

Your computer can also be cooled with the help of cooling devices. These cooling devices have extra air channels that provide the necessary ventilation for the computer and prevent it from overheating. These cooling devices are simple plastic trays on which the computer could be placed and worked on. They generally have small holes on the surface which allow air flow to the base of the computer, when kept on them.
