Why computers overheat: cooling problems, warning signs and safe checks before contacting a repair service.
Common causes
Dust, dried thermal paste, blocked vents or a failing fan can prevent proper cooling.
Safe checks
Use the computer on a hard surface and make sure the air vents are not covered.
When service is needed
Persistent noise, performance drops or shutdowns under load require cleaning and temperature testing.
Interpret temperature alongside symptoms
One temperature reading is not a diagnosis. The model, current workload and any loss of performance all matter. Compare normal use on a desk with the laptop’s previous behaviour. If it becomes hot while apparently idle, check background applications. Stop demanding tasks if shutdowns recur. Inspection determines whether cleaning or another repair is needed.
Practical checklist
- Keep vents clear and use a hard surface.
- Record the application running when the problem appears.
- Do not judge the need for thermal paste replacement by fan noise alone.
