Why is My Laptop Overheating and How to Fix It

“Laptops cram high-performance chips into thin enclosures. Dust, blocked exhaust vents, and dried-out thermal paste cause temperatures to rise, leading to lag and sudden shutdowns.”

Follow these checks systematically to diagnose the root cause:

1. 1Clear Cooling Vents

   Look for exhaust vents. Blow compressed air through them to remove accumulated dust.

2. 2Use on a Hard Flat Surface

   Avoid placing the laptop on beds, blankets, or laps. Soft fabrics block the bottom intake vents, raising temperatures in minutes.

3. 3Monitor Temperature Software

   Use tools like HWMonitor to check CPU/GPU temperatures. Idle temp should be under 50°C; anything above 90°C under load indicates throttling.

4. 4Adjust Power Plan

   Set Windows battery mode to 'Balanced' or limit CPU maximum state to 99% in advanced options to disable aggressive boost clocks.

5. 5Replace Thermal Paste

   If the laptop is over a year old, open the chassis, clean the heatsink, and apply high-quality thermal paste (e.g. Arctic MX-4).

Overheating is usually caused by dust blocking exhaust fins or dry thermal paste that fails to transfer heat from the silicon die to the copper pipes.

Keep these hardware safety rules in mind to protect your circuits:

• Avoid using vacuum cleaners directly on vents as they create static electricity.
• Elevate the back of the laptop using small risers or bottle caps to increase bottom airflow.

If your laptop fan makes a grinding noise or doesn't spin at all, or if temperatures remain above 90°C after cleaning, book a doorstep thermal paste repaste service.
