Why Is My Computer Overheating?
A computer that feels warm during normal use is not necessarily overheating. The concern is excessive heat: very hot surfaces, fans running constantly, major slowdowns, unexpected shutdowns, or repeated warnings about temperature.
What’s happening?
Computers use fans and vents to move heat away from the processor and other components. When airflow is blocked or the computer is working unusually hard, temperatures can rise.
Common causes
- Dust blocking vents or fans
- Using a laptop on a bed, couch, blanket, or other soft surface
- Heavy programs or many browser tabs using the processor
- A fan that is failing or making unusual noises
- A room or workspace that is already very hot
- Internal hardware or cooling problems
Things you can safely try
- Move the computer to a hard, flat surface with open space around its vents.
- Close programs and browser tabs you are not using and see whether the fans settle down.
- Check that vents are not covered by papers, clothing, furniture, or other objects.
- Restart the computer and see whether the heat returns during ordinary use.
- If you can safely see dust around external vents, gently clean the outside without opening the computer or forcing anything into the vents.
Stop here
If the computer becomes extremely hot, shuts down unexpectedly, gives a temperature warning, smells like burning, or makes a failing-fan noise, stop using it and get it checked. Do not open a laptop or desktop power supply yourself.
