Laptop Overheating? Causes, Prevention, and Quick Fixes

Keep temperatures under control and prevent thermal throttling.

1) Clean Dust from Vents and Fans

Dust blocks airflow and raises temperatures.

Use compressed air through the vents; for deep cleaning, open the back panel if comfortable.

2) Replace Thermal Paste

Old paste dries out and loses conductivity.

Apply high‑quality thermal paste between CPU/GPU and heatsink; follow model‑specific guides.

3) Use a Cooling Pad and Hard Surface

Soft surfaces block intake vents.

Keep the laptop on a stand or hard desk; consider a USB cooling pad.

4) Adjust Performance and Fan Profiles

High performance modes create more heat.

Use Balanced mode; enable manufacturer fan control utilities to increase fan curve.

5) Check Background Processes

Runaway tasks can spike CPU/GPU usage.

Use Task Manager to end heavy processes; scan for malware if usage is unexplained.
